Carbonate was analyzed each year, but due to an error in <br />preparing one of earlier spreadsheets, the omission was replicated <br />in subsequent spread sheets. Carbonate data for 1992 was provided <br />within the report in Appendix Z and is provided below: <br />1992 0.84 mg/1 <br />The carbonate data for well OW-14 in 1991 was also included in <br />Appendix B of the 1991 report, but omitted in the spreadsheet. The <br />carbonate concentration was less than detect at .1 mg/1 in well OW' <br />14. <br />If we can provide any additional information, please do not <br />hesitate to call. <br />Sincerely, <br />~'^~~ <br />".A" <br />Michael Galloway <br />cc: E.
