PUBLIC HEALTH ASSESSMENT ADDENDUM
MOTCO, INCORPORATED
TEXAS CITY, GALVESTON COUNTY, TEXAS
ENVIRONMENTAL CONTAMINATION AND OTHER HAZARDS
The environmental media sampling program at MOTCO began with two EPA-sponsored studies by Black And Veatch in 1981 and 1982. Additional sampling was conducted by Woodward and Clyde in 1984 and 1986, and by CH2M Hill in 1984 and 1985. The types of environmental media sampled included surface and subsurface soil, shallow and deep ground water, surface water, sediments, and aquatic biota (fish and crabs). The pit wastes were also sampled. The samples were analyzed for Hazardous Substances List (HSL) metals and copper, volatile and semi-volatile compounds (HSL organics), pesticides and polychlorinated biphenyls (PCBs). Appendix C shows the locations of the monitoring wells, borings, and pits. Appendix D lists the chemical compounds that were analyzed in the laboratory.
We selected and discussed these contaminants based upon the following factors:
In the data tables that follow under on-site contamination and off-site contamination, the listed contaminant does not mean that it will cause adverse health effects from exposures. Instead, the list indicates which contaminants will be evaluated further in the Health Assessment. When selected as a contaminant of concern in one medium, that contaminant will be reported in all media.
The data tables include the following acronyms:
ATSDR Health Assessment Comparison (HAC) values are contaminant concentrations in specific media that are used to select contaminants for further evaluation. These values include Environmental Media Evaluation Guides (EMEGs) and other relevant guidelines. EPA's Reference Dose (RfD) is an estimate of the daily exposure to a contaminant that is unlikely to cause adverse health effects.
We conducted a search of the Toxic Chemical Release Inventory (TRI) for the zip code area containing the MOTCO site. The TRI did not list any facilities having chemical releases in this area for 1987-1989. Industries in the zip code area adjacent to MOTCO reported 59 releases in 1987, 55 releases in 1988, and 47 releases in 1989. Several chemicals included in these reported releases are the same as those identified as MOTCO site contaminants.
1. Soil Contamination
The on-site soil investigation was divided into three general areas of sampling: (1) topsoil (0-6 feet); (2) shallow subsurface (depths to 50 feet); and (3) deep subsurface (depths below 50 feet).
In 1983, 11 surface (0.5-1.0 foot) soil samples were obtained along the northwest, southeast and southwest perimeter dikes at locations that showed visible evidence of dike leakage and five surface soil samples were obtained at locations with no evidence of dike leakage. Woodward-Clyde Consultants screened these samples for volatile and non-volatile organic compounds and metals. Metals, volatile and aromatic compounds were detected in field tests. Metals in the surface soils were further analyzed in the laboratory. Table 1 shows the maximum levels of metals detected in the on-site surface (0.5-1.0 foot) soils. None exceeded available health assessment comparison values.

The major contaminants in shallow subsurface soil samples were semi-volatile compounds (semi-VOCs). (See Table 2.) Semi-VOC contamination was detected as far down as 50 feet. The Polynuclear Aromatic Hydrocarbons (PAHs) fluorene, naphthalene, phenanthrene, and pyrene were detected at depths greater than 50 feet.
The highest volatile organic compound (VOC) levels were located at depths greater than four feet. Benzene, 1,1,2- trichloroethane, and 1,2-dichloroethane were detected at maximum levels of 15 ppm, 640 ppm, and 1200 ppm, respectively.
The highest metal concentrations were located at depths greater than 33 feet below ground surface (BGS). The shallow subsurface soil samples containing the highest levels of contamination were located northeast of Pit 7 and east of Pit 2.
Only a few compounds were detected in the deep subsurface soil. (See Table 3.) In general, the highest concentrations of contaminants in deep subsurface soil occurred at a depths of 53-55 feet. The samples containing the highest concentrations of contaminants were located east of Pit 2 and northeast of Pit 7.

2. Ground-Water Contamination
Eight on-site monitoring wells were sampled. Six of the monitor wells were screened in the shallow aquifer (transmissive zones 1, 2, and 3) and two monitor wells were screened in the deeper aquifer (Upper Chicot). Seven of the wells were located in the eastern part of the site, with one well located northeast of Pit 1.
The majority of the ground-water contamination in the shallow aquifer consists of VOCs although some semi-VOCs and metal contamination were also detected. (See Table 4.) Contaminants with the highest concentrations were 1,2-dichloroethane (3500 ppm), 1,1,2-trichloroethane (250 ppm), vinyl chloride (116 ppm), and benzene (40.45 ppm). In addition, methylene chloride was detected at a concentration of 0.5 ppm. The highest VOC concentrations were found southeast of Pit 7. Low levels of PAHs were detected in the shallow ground water; however, bis(2-chloro-ethyl)ether was detected at 3300 ppm. The highest levels were found in the well located southeast of Pit 7. The highest ground-water metal concentrations were detected northeast of Pit 7 and close to the plant's main entrance. Metals considered contaminants of concern were manganese (9.2 ppm), chromium (0.56 ppm), cadmium (0.48 ppm), and lead (0.45 ppm).
Only two on-site wells draw water from the deeper aquifer. Both wells are located northwest of Pit 7. Contamination in the wells is limited primarily to VOCs, although a few semi-VOCs and metals are present at low levels (see Table 5). The VOCs with the highest concentrations are vinyl chloride (0.68 ppm), 1,2- dichloroethane (0.5 ppm), and 1,1-dichloroethene (0.091 ppm). In addition, benzene was detected at 0.052 ppm.
3. Waste-Pit Contamination
The majority of the on-site wastes at MOTCO are contained in seven unlined waste pits. The maximum pit depth is between 15 and 20 feet, and together the pits cover approximately 4.6 acres. Primary contaminants associated with the waste pits include chlorinated and aromatic hydrocarbons and PAHs. Polychlorinated biphenyls (PCBs) and heavy metals are also contained in the waste pits. (See Tables 6, 7, and 8.)
4. Air Contamination
Air quality monitoring was conducted at the MOTCO site in September 1981, to evaluate the necessary levels of respiratory protection for initial site remediation work. An organic vapor analyzer (OVA) was used. No contaminants of concern were identified as a result of on-site air quality sampling.
