Box 6 <br />Stillwater, MN 55082 <br />Re: Washington County Sanitary Landfill No. 1 <br />Dear Mr. Ryan: <br />The laboratory results of the offsite discharge of water from gradient control well <br />GCl are enclosed. Water samples were collected at the Highway 5 outfall on <br />January 28, 1991. <br />Along with the results, the NPDES Preventative Levels and the Minnesota <br />Department of Health Recommended Allowable Limits (RALs) are listed. The <br />listed RALs are newly established (January 1991) and therefore supersede those <br />referred to in the past. Of the parameters analyzed, only total phenols exceeded a <br />preventative level. Due to this exceedance, weekly sampling at the Highway 5 <br />outfall has commenced and will continue for three weeks as per the NPDES <br />permit. You will be advised of these results when the analyses are complete. <br />Samples will continue to be collected and analyzed on a monthly basis at the <br />Highway 5 outfall for volatile organic compounds, total phenols and total lead. <br />If you have any questions, please feel free to contact me. <br />Sincerely, <br />WENCK ASSOCIATES, INC. <br />Christopher D.
