Appendix C--Investigations and Contaminant Tables
Investigation and related site information were reviewed, and an initial selection was made of contaminants that warrant additional evaluation for deciding (in Public Health Implications Section, beginning on Page 14) whether exposure to them has public health significance. Thus, discussion of the contaminants chosen here, does not imply that human exposure has occurred or that exposure would actually result in adverse health effects. The contaminants selected are presented in Tables C1 - C17, in this Appendix, beginning on Page 52.
Initial contaminant selection considered the following factors:
In constructing Tables C1 - C17, most contaminants that were selected by the preceding criteria in one medium were also included in every other relevant media table. The data tables include selection comparison value information where pertinent, including:
The EPA Toxic Chemical Release Inventory (TRI) also was searched to determine whether it contained information about industrial chemical releases for the area. None of the release information identified in the inventory is pertinent to these evaluations (29).
On-site information described in this subsection was gathered during the following investigations programs:
During the May, 1986 sampling conducted by FIT one sludge sample was taken from each of Pits 1 -4. The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. Chromium exceeded its ATSDR comparison values only for the child who habitually ingests soil-like materials. The following organic contaminants were detected and have no comparison value: benzo(a)anthracene, 2-hexanone, 2-methylnaphthalene, chrysene, and phenanthrene. Lead and potassium were also detected and do not have a comparison value. The contaminants and concentration ranges are listed in Table C1.
During the September, 1987 sampling conducted by Kerr-McGee two sludge samples were taken from Pit 5. No contaminants exceeded ATSDR comparison values. The following organic contaminants were detected but have no ATSDR comparison values: benzo(a)-anthracene and chrysene. During this sampling event, Kerr-McGee did not analyze for inorganic contaminants (Table C1).
During the May, 1988 sampling conducted by TAT nine sludge samples were taken from Pit 5. None of the organic contaminants sampled exceed ATSDR comparison values. The following inorganic contaminants were detected at levels which exceeded ATSDR comparison values: arsenic, cadmium, and chromium. There is no comparison value for lead, mercury, or vanadium (Table C1). Cadmium and chromium concentrations exceed only the values for the child who habitually ingests soil-like materials.
During the 1990-92 sampling performed for the Remedial Investigation Report (RIR), each pit was spot tested for field Ph and acidity and Pit 3 was also tested for ignitability. Deep samples were taken from the waste material sludge in Pits 1, 2, 4, and 5 for total chemical analysis. The following constituents exceeded ATSDR comparison values: antimony, arsenic, barium, beryllium, cadmium and manganese. There is no comparison value for chrysene, copper, lead, 2-methylnaphthalene, phenanthrene and vanadium. Antimony, barium, cadmium, chromium, and manganese exceed only comparison values for the child who habitually ingests soil-like materials (Table C1).
During the May, 1986 sampling conducted by FIT one sludge sample was taken from each of Pits 1 -4 and analyzed for radioactive contaminants. The following radioactive contaminants were detected above national background levels: radium-226 (surface), radium-228 (oral), thorium-232 (surface), thorium-230 (surface), thorium-228 (surface), thorium-227 (surface), and lead-210 (oral and surface). Other radionuclides analyzed for included uranium-233,234 and polonium-210 (Table C2).
During the May, 1991 sampling conducted by Kerr-McGee, 20 samples were collected from Pit 4 (10 random and 10 biased radioactive "hot spots"), 15 samples from Pits 1, 2, and 3, and 12 samples in Pit 5 to determine radioactive contamination present at the Kerr-McGee Cushing refinery. The following radioactive contaminants were detected at levels above background: thorium-232 (surface), gross gamma exposure (surface) and total uranium (Table C2).
In September, 1944, Kerr-McGee sampled 21 hydrocarbon waste deposits, which are smaller than Pits 1 - 5; deposit locations were identified by examining aerial photographs and by other site activities (Table C1). The following inorganic and organic contaminants were found at levels that exceed ATSDR comparison values: antimony, arsenic, barium, benzo(a)pyrene, beryllium, cadmium, chromium, manganese, nickel, silver, and zinc. There are no comparison values for aluminum, benzo(a)anthracene, benzo(b)fluoranthene, benzo(ghi)perlene, calcium, cobalt, copper, dibenzofuran, iron, lead, magnesium, mercury, 2-methylnaphthalene, naphthalene, phenanthrene, potassium, and sodium. Chromium, pyrene, silver, and zinc exceed only comparison values for the child who habitually ingests soil-like materials. Barium, cadmium, manganese, and nickel exceed comparison values for all children.
During the May, 1986 sampling conducted by FIT eight soil samples were taken, at an unstated depth. Locations of the samples are described as low concentration soil samples taken from north, south and west of Pit 4, low concentration samples taken south of the north fence line in an old tank area, low concentration sample taken from a ponding area south of Pits 1,2 and 3, and a low concentration sample taken near an above ground tank area north of the south boundary. The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. The following organic contaminants were detected but have no comparison value: chrysene, 2-hexanone, and phenanthrene. N-nitrosodiphenylamine levels exceeded the ATSDR comparison value. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic, chromium, nickel, and zinc (Table C3). Calcium, cobalt, copper, iron, lead, and mercury do not have comparison values. The concentrations of chromium and nickel exceed only the comparison value for the child who habitually ingests soil-like materials.
During the May, 1988 sampling conducted by TAT six soil samples from an unstated depth were taken. The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. This site assessment did not detect any organic contaminants at levels which exceed ATSDR comparison values. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic, barium, cadmium, chromium, manganese, and nickel (Table C3). Copper and iron do not have comparison values. Of these inorganic contaminants, concentrations of barium, cadmium, chromium, manganese, and nickel exceed only the comparison value for the child who habitually ingests soil-like materials.
During the 1990 to 1992 sampling for the remedial investigation report, several samples of soil and rock were taken (depth unstated). Inorganic contaminants that were detected at levels that exceed ATSDR comparison values include: arsenic, barium, beryllium, chromium, manganese, and nickel (Table C3). Of these, barium, chromium, manganese, and nickel exceed only the comparison value for the child who habitually ingests soil-like materials. Calcium, cobalt, copper, iron, lead, were elevated, but do not have comparison values. Analyses for VOCs and SVOCs showed only ethylbenzene (not listed in Table C3) was detected at a very low concentration.
During the May, 1986 sampling conducted by FIT eight soil samples were taken at unstated depths from the Kerr-McGee site and analyzed for radioactive contaminants. The following radioactive contaminants were detected at elevated levels: radium-226, uranium-233, and -234, uranium-235, thorium-232, natural thorium, thorium-230, thorium-228, thorium-227, and lead-210. Samples also were analyzed for radium-228 and polonium-210 (Table C2). Background concentrations of radium-226/228, uranium-234/238 and thorium-232 radionuclides are typically 1-4 pCi/g. The typical background for uranium-235 is about 0.02 pCi/g. Those radionuclides that are decay products of uranium and thorium have the same general values if the soils are undisturbed; these include, but are not limited to, Pb-210, Th-230/228, Po-210, Bi-214, and Pb-214. Background levels of gamma radiation are not as standard, as they are dependent on altitude and geology. A rule of thumb is that background gamma radiation levels are on the order of 30 µR/h or less.
During the November, 1989 sampling conducted by Kerr-McGee twelve soil samples were collected. The following radioactive contaminants were detected at elevated levels: radium-226, uranium-238, thorium-232, and gross gamma in and around the former uranium/thorium processing buildings. These were the only radioactive contaminants analyzed for in this investigation (Table C2).
During the May, 1991 sampling conducted by Kerr-McGee approximately 200 soil samples were collected for radiologic analyses. Soil samples indicated that the following radioactive contaminants were present above background values: uranium-233 and -234, uranium-235, uranium-238, thorium-232. Radium-226 was analyzed for in some isolated samples and the uranium isotopic composition was used to determine the percent of enriched uranium present. These samples were from various depths and were collected from excavations of trench areas and other "hot spots" identified in the gamma survey (Table C2).
As part of the site decommissioning process, analyses was reported in 1994 for about 40 soil samples taken in each of four large segments of the property used for oil refining and storage activities (Table C2). For comparison purposes, background levels also are shown in that table for soil sampled off-site. Each of the locations where abnormal values were recorded will be remediated.
During the May, 1986 sampling conducted by FIT six sediment samples were taken from Skull Creek or its tributaries, three of which were on-site samples (Table C4). The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: barium, chromium, and manganese. Their concentrations exceed only the comparison value for the child who habitually ingests soil-like materials. Lead does not have a comparison value. Benzo(a)pyrene was the only organic compound that exceeded ATSDR comparison values. The following organic contaminants were detected and have no comparison value: cyclohexanes (several); cyclopropane, 1-methyl-2-(methylp); dimethyl decane; dimethyl heptane; hexane, 2,2-dimethyl; hexanol, 3-methyl; isoctanol; oxirane, 2-(1,1-dimethylethyl)-3-ethyl; pentane, 2,3-dimethyl; 1-pentene, 2,4-dimethyl; trichloropropylene; and trimethyl pentane.
During the September, 1987 sampling conducted by Kerr-McGee three sediment samples were taken to assess the sediments located in Skull Creek near Pit 5 (Table C4). No inorganic contaminants were analyzed. Chrysene and naphthalene are the only organic contaminants which were detected that do not have an ATSDR comparison value. Other detected organic contaminants do not exceed a comparison value.
During the March 1988 sampling conducted by TAT for evaluation of Property A, one sediment sample was taken from Skull Creek within the eastern Kerr-McGee boundary (Table C14). The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic, barium, beryllium, chromium, and manganese. Calcium, cobalt, copper, lead, and vanadium have no comparison values. Barium, chromium, and manganese exceed only those comparison values for the child who habitually ingests soil-like materials.
During the May, 1988 sampling conducted by TAT four sediment samples were taken from Skull Creek near Pit 5. The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: antimony, arsenic, barium, beryllium, cadmium, chromium, and manganese (Table C4). Cobalt, copper, lead, mercury, and vanadium have no comparison values. No organic contaminants were detected. Antimony, barium, cadmium, chromium, and manganese exceed only those comparison values for the child who habitually ingests soil-like materials.
During the 1992 sampling for the RIR seven sediment samples were collected on-site. For samples taken from tributaries near Pits 1, 2, 3, and 4, arsenic, barium, beryllium, chromium, and manganese were detected at levels that exceed ATSDR comparison values (Table C4). There is no comparison value for cobalt, copper, iron, lead, and vanadium. Chrysene and also benzo(ghi)perylene (which is not listed on Table C4) were detected at a very low levels and have no comparison value. Barium, chromium, and manganese exceed comparison values for the child who habitually consumes soil-like materials. For samples taken on site from Skull Creek (including some taken adjacent to Pit 5), arsenic, barium, beryllium, chromium, and manganese were detected at levels that exceed ATSDR comparison values. There is no comparison value for calcium, cobalt, copper, iron, lead, magnesium, mercury, and vanadium. Chrysene and phenanthrene were detected at very low levels and have no comparison values. Barium and chromium exceed comparison values for the child that habitually consumes soil-like materials, while manganese levels exceed ATSDR comparison values established for all children.
During the May, 1986 sampling conducted by FIT three sediment samples were taken from the Kerr-McGee site and analyzed for radioactive contaminants. The following radioactive contaminants were detected: radium-226, thorium-228, and lead-210 (Table C2). ATSDR is not aware of a substantive body of information about background radionuclide concentrations in stream or river sediment. It is reasonable to believe concentrations are similar to background levels in soils (described earlier in this section) although solutioning is likely to result in somewhat lower levels for certain nuclides.
During the November, 1989 sampling conducted by Kerr-McGee two sediment samples were collected. Radium-226 and thorium-232 were detected (Table C2).
During the May, 1991 sampling conducted by Kerr-McGee 12 sediment samples were collected from 4 locations in Skull Creek for radioanalysis. Sediment samples indicated that the following radioactive contaminants are present: thorium-232, and gamma exposure along the creek banks (Table C2).
Groundwater - Monitoring Wells
In March, 1990 Kerr-McGee sampled 41 monitoring wells on the property. FIT sampled 9 monitoring wells that are located on the site near the waste pits in 1986. The following inorganic contaminants from the 1990 sampling event were detected at levels which exceed ATSDR comparison values: arsenic, barium, beryllium, cadmium, chromium, lead, manganese, mercury, and nickel. Aluminum, calcium, cobalt, iron, magnesium, potassium, sodium, and vanadium have no comparison values. The levels of barium, chromium, manganese, nickel, and vanadium exceed the comparison values established for both children. The following organic contaminants were detected in the 1990 sampling at levels which exceed ATSDR comparison values: benzene, bis(2-ethylhexyl)phthalate, and naphthalene (Table C5). 2-Methylnaphthalene was also detected but does not have a comparison value.
In 1990-92 extensive sampling was conducted for the RIR. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: antimony, arsenic, beryllium, cadmium, chromium, lead, manganese, nickel, and selenium. Calcium, cobalt, magnesium, potassium, and sodium were detected at elevated concentrations but do not have comparison values. Organic contaminants detected which exceed ATSDR comparison values include: benz(a)anthracene, benz(a)pyrene, bromodichloromethane, chrysene, and naphthalene. 2-Hexanone and 2-methylnaphthalene were also detected but do not have comparison values (Table C5). The levels of antimony, cadmium, chromium, manganese, nickel, and vanadium exceed the comparison values established for both children and adults. The 1990-92 sampling also indicated elevated levels of sulfates (22.1-9,190 mg/L) in the groundwater monitoring wells. The Vamoosa-Ada Aquifer had maximum sulfate levels of 393 mg/L. These are very close to and exceed the EPA Proposed Maximum Contaminant Levels for sulfate.
In May, 1986, FIT sampled 9 monitoring wells that are located on the site near the waste pits; the following radioactive contaminants were detected: radium-226, radium-228, uranium-233 and -234, uranium-235, uranium-238, thorium-228, lead-210, and polonium-210 (Table C6) The concentrations of radionuclides in monitoring wells are well below the proposed MCLs. In an 1991 EPA survey as reported in the Federal Register, approximately 72% of the sites had uranium levels above 0.1 pCi/L and 70% of those sites had levels between 0.1 and 20 pCi/L (31).
During the May, 1986 sampling conducted by FIT two of the five surface water samples were taken from on-site locations. The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. The only organic contaminant detected at a level which exceeds an ATSDR comparison value (derived for drinking water) is bis (2-ethylhexyl)-phthalate. The following inorganic contaminants were detected at levels which exceed ATSDR drinking water comparison values: arsenic, beryllium, cadmium, chromium, lead, manganese, and selenium (Table C7). Calcium, iron, magnesium, potassium, and sodium do not have comparison values.
During the September, 1987 sampling conducted by Kerr-McGee three on-site surface water samples were taken and sampled for organic contaminants. Benzene, bis(2-ethylhexyl)phthalate, and trichloroethylene were detected at levels which exceed ATSDR comparison values (derived for drinking water)(Table C7).
During the March, 1988 sampling conducted by TAT to characterize Property A off site, one surface water sample also was collected onsite in Skull Creek near the eastern boundary of the Kerr Mc-Gee property (Table C7). Manganese was detected at levels which exceed ATSDR comparison values (derived for drinking water) (Table C7).
During the May, 1988 sampling conducted by TAT four surface water samples were taken from on-site locations and analyzed for organic contaminants. The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. Benzene, bis(2-ethylhexyl)phthalate, and bromodichloromethane were detected at levels which exceed ATSDR comparison values (derived for drinking water) (Table C7).
Surface water samples were collected for the 1990-92 RIR. For samples taken from creek tributaries near Pits 1, 2, 3, and 4, inorganic contaminants detected at levels that exceed ATSDR comparison values include: antimony (for child and adult), beryllium, chromium, manganese (for child and adult), nickel, and vanadium. Aluminum, calcium, cobalt, iron, magnesium, potassium, and sodium were also detected at elevated concentrations but do not have comparison values. Organic contaminants that exceed comparison values include: benzo(a)pyrene, benzo(a)anthracene, and N-nitrosodiphenylamine. Phenanthrene was also detected but do not have comparison values (Table C7). Samples taken on site in Skull Creek, (including samples adjacent to Pit 5) showed concentrations were less than found in the tributaries (possibly due to dilution effects of creek flow). Magnesium and sodium are slightly elevated but do not have a comparison value. 2-Methylnaphthalene and a few other organic compounds not shown in Table C7 were detected at low concentrations for which there are no comparison values.
Kerr-McGee conducted ambient air particulate sampling on site in 1994 to evaluate gamma dose levels via that medium (Table C2). The sampling results suggest that the values recorded were at acceptable levels.
In 1994, Kerr-McGee placed thermoluminecent dosimeters at multiple locations onsite, including along on fences surrounding some Radioactive Materials Areas. (Table C2). The environmental gamma dose recorded was at acceptable levels.
B. Off-site Investigation Data
The data presented in this subsection were collected during the following site investigations:
During the March, 1988 sampling conducted by TAT to characterize off-site sludges on Property A, located east of the Kerr-McGee northeastern boundary (Figure 1), five sludge samples were taken. Sludges there are believed to result from the former refinery operations conducted on that property. Analysis of the samples indicated the presence of the following inorganic contaminants at levels which exceed ATSDR comparison values only for children that habitually ingest soil-like materials: barium, manganese, and silver (Table C8). Chromium exceeded the comparison values for all children. Copper, iron, lead, and sodium do not have comparison values. Samples were analyzed for VOCs, SVOCs, and other organic compounds; none were mentioned in the data report. No radionuclide analyses were performed. Contaminants found in sludge are most likely associated with former refinery operations conducted on that property.
During the March, 1988 sampling conducted by TAT to characterize off-site soils on Property A, several soil samples were taken. Contaminants found in soil there are likely to be the result of former refinery operations on the property and background soil conditions. Analysis of the samples indicated the presence of the following inorganic contaminants at levels which exceed ATSDR comparison values: antimony, arsenic, barium, beryllium, cadmium, chromium, manganese, and zinc (Table C9). No ATSDR comparison value is available for calcium, cobalt, copper, iron, lead, mercury, thallium, and vanadium in soil. Antimony, barium, cadmium, chromium, manganese, and zinc exceed the comparison value for children who habitually consume soil-like materials. Samples were analyzed for VOCs, SVOCs, and other organic compounds. The source document reports that unidentified semivolatiles were detected in soils but does not identify concentration or state whether they were found in sample(s) on or off Property A.
During that same sampling event, one sample was taken on residential property immediately north of Property A. Contaminants found on that property might be the result of aerial deposition from former industrial activities on Property A or Kerr-McGee properties or from background conditions. Analysis showed the presence of the following inorganic contaminants at levels which exceed ATSDR comparison values: arsenic, barium, chromium, and manganese (Table C9). No ATSDR comparison value is available for lead and mercury in soil. Barium, chromium, and manganese exceeded the comparison value for children who habitually consume soil-like materials. Samples were analyzed for VOCs, SVOCs, and other organic compounds. The source document reports that unidentified SVOCs were detected in soils but does not identify concentration or state whether they were found in sample(s) on or off Property A.
Samples also were taken in 1995 at the Deep Rock School, located on the east side of Linwood Avenue, near Kerr-McGee's southeast property boundary (Table C9). Contaminants there are likely to result from background conditions. Analysis of the samples showed that barium and chromium slightly exceeded comparison values only for children who habitually ingest soil-like materials. No ATSDR comparison value is available for lead in soil. Samples were analyzed for VOCs and SVOCs; none were detected. A radioactivity survey on school property yielded readings between 10 and 15 microRoengtens per hour; background levels were 10 microRoengtens per hour--these values indicate there are no substantive radioactive levels on the school property.
In 1995, several samples were taken of soil on a large property south of Property A, by Deep Rock Road, that has a residence and analyzed for radioactivity (Table C9). One sample was by the house, the others were by Skull Creek. Results show no evidence of elevated radioactivity.
Investigation in 1994 by Kerr-McGee for the final radiation survey of four large areas used for oil refining and storage activities on site included results for 54 background samples taken off site; most were taken near the west property line, but all within ½ mile of the property. Those data have been included in Table C2 to provide a convenient comparison with results for on-site soils. Typically, ATSDR finds that background concentrations of radium-226/228, uranium-234/238 and thorium-232 radionuclides are on the order of 1-4 pCi/g. The typical background for uranium-235 is about 0.02 pCi/g. Those radionuclides that are decay products of uranium and thorium have the same general values if the soils are undisturbed; these include, but are not limited to, Pb-210, Th-230/228, Po-210, Bi-214, and Pb-214. Background levels of gamma radiation are not as standard, as they are dependent on altitude and geology. A rule of thumb is that background gamma radiation levels are on the order of 30 µR/h or less.
During the May, 1986 sampling conducted by FIT six sediment samples were taken, three of which were off-site samples. Contaminants found are likely to result from former operations on Kerr-McGee property and from background conditions The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic, chromium, and manganese. Cobalt, iron, and lead do not have comparison values. Chromium and manganese exceed the comparison value for children that habitually consume soil-like materials. Benzo(a)pyrene was the only organic contaminant detected which does have an ATSDR comparison value (Table C10).
During the March, 1988 sampling conducted by TAT, two sediment samples were collected in Skull Creek and a tributary near Property A, downstream of the Kerr Mc-Gee property. The contaminants found are likely to result in part from former activities at Kerr-McGee and Property A and from background conditions. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic, barium, beryllium, chromium, and manganese (Table C10). Cobalt, copper, iron, lead, mercury, and vanadium do not have comparison values. Barium an manganese exceed the ATSDR comparison value only for children who habitually ingest soil-like materials. Samples were analyzed for VOCs, SVOCs, and other organic compounds. The source document reports that unidentified SVOCs were detected in sediment but does not identify location or concentration.
During the March, 1988 sampling conducted by TAT to characterize Property A, several sediment samples were collected in drainage courses and in a pond on the property. The contaminants found are likely to result from former refinery activities on the property and \from background conditions. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic, barium, beryllium, chromium, manganese, mercury, and zinc (Table C10). Cobalt, copper, iron, lead, mercury, and vanadium do not have comparison values. Barium, chromium, manganese, mercury, and zinc exceed the ATSDR comparison value only for children who habitually ingest soil-like materials. The source document reports that unidentified SVOCs were detected in sediment but does not identify location or concentration.
In December, 1995 two sediment samples were taken from Skull Creek and a tributary downstream of the site by a team of Kerr-McGee and ODEQ personnel who split most of the samples. Some of the contaminants found may result from refinery operations on either Kerr-McGee or Property A. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: antimony, arsenic, barium, beryllium, chromium, and manganese (Table C10). Aluminum, calcium, cobalt, copper, iron, lead, magnesium, mercury, potassium, sodium, and vanadium do not have comparison values. Barium, chromium, and manganese exceed the ATSDR comparison values only for children who habitually ingest soil-like material. Twenty-three common organic chemicals were detected. Fifteen of those have ATSDR comparison values; none of the comparison values were exceeded. The remaining 8 contaminants have no comparison values. Information about organic analyses is summarized in a note at the end of Table C10. Radiologic analyses of creek sediments showed values that were at background levels (see note at end of Table C11).
During the May, 1986 sampling conducted by FIT three sediment samples were taken from Skull Creek and tributaries, up and down stream of the site, and analyzed for radioactive contaminants. The following radioactive contaminants were detected: radium-226, thorium-228, and lead-210 (Table C11). ATSDR is not aware of a substantive body of information about background radionuclide concentrations in stream or river sediment. It is reasonable to believe concentrations are similar to background levels in soils (described earlier in this section) although solutioning is likely to result in somewhat lower levels for certain nuclides.
During the September, 1989 sampling conducted by FIT, five Cushing municipal wells (all public wells are located more than 1 miles to the south and southeast of the site) were sampled. Contaminants found are likely to arise from background conditions. The samples were analyzed for inorganic contaminants. Lead and manganese levels slightly exceeded ATSDR comparison values derived for drinking water. Iron and sodium were the detected at elevated levels but do not have ATSDR comparison values (Table C12). Samples were analyzed for volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), and other organic chemicals. None were detected. During the November, 1989 sampling conducted by FIT, three of the five public wells sampled in September 1989 were re-sampled. The samples were analyzed for inorganic contaminants and a limited number of organic contaminants. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic and beryllium. Calcium, cobalt, and sodium have no comparison values (Table C12). Samples were analyzed for VOCs, SVOCs, and other organic chemicals. None were detected.
ODEQ has provided results of samples taken in several public wells in 1994 and 1995 (Table C12). Contaminants found are likely to arise from background conditions. Samples were analyzed for inorganic parameters, for VOCs and a few semivolatile compounds SVOCs. The following inorganic contaminants were detected at levels which exceed ATSDR comparison values: arsenic and manganese. Iron and sodium have no comparison values. No organic chemicals were detected.
The December, 1989 document Comments of Kerr-McGee Corporation in Response to EPA's Proposed Listing of the Cushing, Oklahoma Site, includes a radioactive chemical sampling analysis of municipal water wells. Gross alpha measurements are below the MCL; gross beta was measured at a levels of 2.65 to 3.39 pCi/L, below the Primary Drinking Water Standards gross beta screening value of 50 pCi/L. The November, 1989, resampling of public wells by FIT included analysis for radium-226, uranium-234, 235, 238, thorium-227, 228, 230,232, bismuth-214, lead-214, and gross alpha (Table C13). There is inconclusive data to determine the source of several of the radionuclides in municipal wells. The concentrations of radionuclides are well below the MCLs.
During the March, 1988 sampling conducted by TAT to characterize Property A, a private well sample was collected on that property (Table C14). Analysis of the sample did not identify any inorganic contaminants at levels which exceed ATSDR comparison values. No ATSDR comparison values are available for calcium, iron, potassium, and sodium. No VOCs, semivolatile compounds (SVOCs), or other organic chemicals were detected. This residence is not connected to the public water system and, therefore, is probably using the well as a source of potable water.
Samples were also taken in March 1988 from three wells located within ¼ mile of the site--this includes one well at a former residence that had been "on site" (within the site boundaries defined in Figure 1) on Linwood Avenue, near Deep Rock Road. None of the maximum values reported were from that well. The other wells sampled are on the east side of Linwood Avenue; one is immediately north of Property A and the other is a short distance south of Skull Creek. ATSDR's information suggests that those wells either have not been used for potable water or have not been used in that way for many years. Samples were taken during the November, 1989 sampling by FIT, and the 1989 and 1990 sampling by the Payne County Health Department for OSHD, and one well was resampled by ODEQ in July, 1995 (Table C14). Sample analyses showed the following inorganic contaminants at levels which exceed ATSDR comparison values; arsenic, beryllium, lead, manganese, and zinc. Cobalt, iron, and sodium do not have comparison values. Two wells were analyzed for VOCs, SVOCs and other organic chemicals; the other was analyzed for VOCs. Some unidentified SVOCs were detected in the well located just north of Property A. No organic compounds were detected in the other two wells.
During the December, 1989 and January 1990 sampling conducted by the Payne County Health Department for OSHD, nine private wells located ½ to 3 miles from the site were sampled and analyzed for several inorganic contaminants (Table C14). A few of those are used as a potable water source potable The following were detected at levels exceeding the ATSDR comparison values: lead and manganese. There are no comparison values for iron. One of the nearest of this group of wells was analyzed for VOCs; none were detected.
During the December 1995 sampling by Kerr McGee and ODEQ, a sample was taken (and split) from a private well being used for potable water supply immediately east of the site (south of Property A) on Deep Rock Road (Table C14). None of the metals detected exceeded ATSDR comparison values. VOCs and SVOCs were analyzed for and not detected. The split samples also were analyzed for radioactivity (Table 15B); values were not elevated.
During the 1989 and 1990 sampling conducted by the Payne County Health Department for OSHD, eleven private wells were sampled for radioactivity. One well is on former private property located "on site" near Linwood and Deep Rock Roads, by the east edge of the site. The detected radioisotopes were below levels of public health concern (Table C15).
The November, 1989 sampling by FIT of private wells included a well sampled for radium-226, uranium-234, 235, 238, thorium-227, 228, 230, 232, bismuth-214, lead-214 and gross alpha contamination (Table C15). The values recorded were below levels of health concern.
During the May, 1986 sampling conducted by FIT three of the five surface water samples were taken from off-site locations of Skull Creek and its tributaries. The samples were split, EPA possessing one set of the samples and Kerr-McGee the other. The samples were analyzed for both inorganic and organic contaminants. The following inorganic contaminants were detected above ATSDR comparison values (derived for use as drinking water): arsenic, beryllium, cadmium, lead, and manganese. Calcium, potassium, and sodium concentrations were elevated but do not have comparison values. No organic contaminants were present above ATSDR comparison values (Table C16).
During the March, 1988 sampling conducted by TAT, two samples of water were taken from Skull Creek and a tributary near Property A, downstream of the Kerr-McGee property (Table C16). Manganese was detected at levels above its ATSDR drinking water comparison value. No comparison value is available for sodium. No organic compounds were detected.
During the January and February, 1989 sampling conducted by the Payne County Health Department four area ponds were sampled for the following inorganic contaminants: barium, copper, iron, lead, manganese, sodium, and zinc. Only manganese concentrations exceed ATSDR drinking water comparison values (Table C16). None of the samples were analyzed for organic compounds. None of the ponds are in watersheds that would be affected by site runoff. Two ponds are more than a thousand feet from the southwest part of the site. A third is several hundred feet north of the property, and the fourth is about a thousand feet east.
During the March, 1988 sampling conducted by TAT to characterize Property A, two surface water samples were collected from Skull Creek and a tributary downstream from Property A. Analysis of the samples indicated the presence of the following inorganic contaminants at levels which either exceed an ATSDR comparison value: manganese, or they have no comparison value: potassium, and sodium (Table C16). Organic compounds were not detected.
During the December 1995 joint sampling by Kerr-McGee and ODEQ, several samples were taken of creek water downstream from the site. Representative concentration information are provided on Table C16. Organic compounds were not detected. No ATSDR comparison values were exceeded. Radiologic analyses results are provided in Table C17. Values are not elevated and are consistent with data found in surface water reports issued by EPA in their Environmental Radiation Ambient Monitoring System program reports..
During the Oklahoma Department of Health's Private Well and Pond Sampling near the Kerr-McGee Cushing Refinery, conducted from October, 1989 through April, 1990, four ponds were sampled for radioactivity. Gross alpha measurements are below the MCL; gross beta was measured at a levels of 2 to 4 pCi/L. These are not present at levels of concern. Radium-226/228 appears to be slightly elevated above the current MCL of 5 pCi/L but below the proposed MCL (Table C17).
During the May, 1986 sampling conducted by FIT four off-site surface water samples were collected from Skull Creek. The following radioactive chemicals were detected: radium-226, radium-228, uranium-233+234, uranium-238, thorium-232, thorium-230, thorium-228, lead-210, and polonium-210 (Table C17). These are not present at levels of concern.
