APPENDIX C.

Public Comments & Responses PUBLIC COMMENTS AND RESPONSES
1.COMMENTThe report fails to mention in any respect the cleanup work done in anEPA supervised removal action in 1983 and 1984.

RESPONSEThis information can be found in the document under the Site Descriptionand History section, page 2, last paragraph.

2.COMMENTThe report suggests on page 38 that the elevated levels of sodium, andpotentially other contaminants, could be migrating from the site to privateresidential wells. The report also suggests that the site is the cause of theelevated levels of sodium found in the residential wells.

RESPONSEThis information was reviewed and appropriate changes were made to thedocument. There is no evidence to indicate that the site is the source ofthe elevated levels of sodium in the groundwater. This has been stated inthe document in the first paragraph of the Conclusions section.

3.COMMENTThere are no residential wells between the site and Finley Creek.

RESPONSEThis information was reviewed. Please note that there is one private wellbetween the site and Finley Creek (see Figure 3-6 of the ECC RI/FSreport.)

4.COMMENTNo geological assessment or description of the flow patterns of theaquifers under the site are mentioned in the report.

RESPONSEInformation on groundwater flow and geological assessment were addedto the document under the Demographics, Land Use, and Natural Resource Use section.

5.COMMENTIf sodium is not in the on-site well, how could the sodium in the privatewells be coming from the site?

RESPONSEIt was not our intention to imply that the site was the source of thesodium. This disclaimer is in the document in the first paragraph underthe Conclusions section.

6.COMMENTThe analytical data in the report is approximately 10 years old. Thesenumbers are not representative of current conditions and/or the potentialrisks to private well users.

RESPONSEThe purpose of the public health assessment is to assess all past, present,and future exposure pathways. In order to do this, all data collected onthe site is evaluated. As was mentioned in your comment, there has notbeen any recent additional analytical testing of this site. As the ISDHdoes not perform any environmental sampling, we are dependent on thesampling results from other agencies. Therefore, we can only evaluatedata that is available and recommend that additional sampling is neededfor a particular media.
7.COMMENTThe ISDH did not include qualifiers in the data tables.

RESPONSEIn the writing of the public health assessment, any data that is estimated orbelow their detection limit is not used in the report. Any qualification ofthe data is included in the section entitled Quality Assurance and Quality Control. In order to not just reproduce the actual reference document, werecommend that the reader refer back to the original document fromwhich the data were retrieved. This qualifier has been added to thedocument.

8.COMMENTSample depths appear to have been rounded to the nearest foot. This isnot mentioned in the document.

RESPONSEThis information was reviewed and appropriate changes were made to thedocument.

9.COMMENTThe concentration range shown for aldrin in the data table found on pageB-1 is incorrect; it should read 20 ppm. The sample location should readAE-AG.

RESPONSEThis information was reviewed and appropriate changes were made to thedocument.

10.COMMENTThe sample depth for 1,2-dichlorobenzene should be 0-1 not 8-1.

RESPONSEThis information was reviewed and appropriate changes were made to thedocument.

11.COMMENTThe report suggests that the site may have adversely affected the receivingstream, although all analytical data suggest otherwise.

RESPONSEOff-site surface water was determined to be a potential exposure pathwayas Finley Creek and its associated tributary are principal surface drainageareas for the site. The report clearly states under the Pathway Analysessection (off-site surface water), "This medium is not considered a mainsource of contaminant exposure to humans."

12.COMMENTThere are concerns that there is not evidence that there was no arsenic found in the mussels prior to the freshwater mussel study performed.

RESPONSEThis comment is beyond the scope of this document. The informationregarding the freshwater mussel study was taken from the Ecology andEnvironment 1986 Remedial Investigation and Feasibility Study.

13.COMMENTThe hypothetical future risks, if any, need to be discounted by the siteremedial work expected to be done later this year under the existingConsent Decree.

RESPONSEWe are responsible for noting any potential risk to human health in thepublic health assessment. Even though the potential risk is proposed to beremoved, we have to mention this risk none the less.

14.COMMENTThe recommendations should not suggest that the private wells areaffected by the site as there is no proof that the wells arehydrogeologically connected with the site.

RESPONSEThis information was reviewed and appropriate changes were made to thedocument. Please see page 21 under Environmental Data Gaps.

15.COMMENTThe recommendations should reflect the fact that recommendation 2, 7, 8,and 10 will be met by the Consent Decree.

RESPONSEThis information was reviewed and appropriate changes were made to thedocument.
