Chlorides were <br />up from 325 parts per million (ppm) to 345 ppm. However, most of the <br />other parameters showed lower levels of contaminants compared to the <br />November, 1984 test results. EPA's Recommended Primary Drinking Water <br />Standard for chlorides is 250 ppm. <br /> <br />In addition to contamination in Well No. 8, the conventional and <br />miscellaneous parameters in Well No. lA were substantially higher than <br />the November, 1984 levels. Those changes are as follows: <br /> <br />Parameter <br /> <br />February, 19_85 <br /> <br />November, 1984 <br /> <br />Chloride <br />Alkalinity as CaCO <br />Total Organic CarbOn <br />Hardness as CaCO3 <br />Specific Conductance <br /> <br />35.7 mg/1 9.9 mg/1 <br />544 mg/1 187 mg/1 <br />10.1 mg/1 1 mg/1 <br />550 mg/1 233 mg/1 <br />924 mg/1 490 mg/1 <br /> <br />If you have any questions in regard to the lab results, please let me <br />know. <br /> <br />Yours truly, <br /> <br />HAKANSON ANDERSON ASSOCIATES, INC. <br /> <br />Peter R.
