minnesota department of health <br />717 s.e. delaware st. minneapolis 55440 <br />~612 2W 5,'2~ <br /> September 26, <br /> <br />1980 <br /> <br />Lloyd G. Schnelle <br />City Administrator, Ramsey <br />15153 Nowthen Boulevard NW <br />Ramsey, MN 55303 <br /> <br />Dear Mr. Schnelle: <br /> <br />Enclosed is a copy of my report on the Department of Health's <br />investigation of the public health concerns rela~ing to the <br />landfill at Ramsey. <br /> <br />Based on an evaluation of medical testing to date, analyses of <br />air, soil and groundwater samples, and a review of the <br />scientific literature, there does not appear to be a serious <br />health risk to residents from the migration of landfill de- <br />composition products at this time. However, because the <br />generation of landfill decomposition products is an ongoing <br />process, one that will continue far into the future, a long- <br />term surveillance program is recommended. <br /> <br />Specifically, the program should include: 1) evaluation of <br />the gas collection system:efficiency,-and 2) evaluation of <br />groundwater supply integrity. <br /> <br />Additionally, since the odor-causing component of the land- <br />fill gas has not been identified, further analysis of con- <br />centrated landfill gases should be considered. This service <br />could be provided by the Minnesota Department of Health after <br />new instrumentation becomes operational sometime in 1981. <br /> <br />If you have any questions regarding the report or if I can <br />be of further assistance, please let me know. <br /> <br />.Sincerely, <br /> <br />Ingr~d Ritchie, Ph D. <br />Research Scientist <br />Section of Health Risk Assessment <br /> <br />IR/ncc <br /> <br />Enclosure <br /> <br />cc:~%Tom Clark, MPCA <br /> Bob Hutchison, Anoka County <br /> Don Otter, Waste Management, Inc. <br /> Roman Koch, Engineer <br /> Fred $oucie, Attorney-at-Law <br />anequaloppo~umtyemoloyer ~¢~ <br /> <br /> <br />
