The data from Legend Technical Services, Inc. shows no volatile organic <br />compounds (VOC) were detected in either well. <br /> <br />Lead was detected in both wells at concentrations sli htl above the recommended allowable <br />limit (RAL for drinkin water of 0.020 mg!1 established b the Minnesota Depanment or <br />ea IS standard was recently revised downward from 0.050 mg/L Lead can occur from "- <br />a variety of sources and is naturally occurring to some extent. At this time, we do not believe <br />the lead in your water supply is from Custom Motors as no VOC compounds were detected <br />which are anticipated to migrate faster than lead. Other possible sources of lead are pipe solder, <br />suspended solids or on-site sources. <br /> <br />You may wish to consider using bottled water or filtering your drinking water. RALs are <br />established based on a lifetime of exposure, usually 70 years, assuming a consumption of two <br />(2) liters per day of water, and then set at some risk level where a fraction of the population <br />would experience some health effect usually the one in one hundred thousand or one in one <br />million level. <br /> <br />Should you have any questions, please contact Steve Rohlf or me. Thank you. <br />~ <br /> <br />Sincerely, <br /> <br />B.A. LIESCH ASSOCIATES, INC. <br /> <br />... <br /> <br />!k~:f/V~)- <br /> <br />;thn Lichter, P.E. <br /> <br />cc: Mr. Steve Rohlf <br />maw:ltrl1894.wp/GO <br />
