Montana State Library 19921115 map Helena, Montana Montana State Library These data include layers whose former names on the NRIS web site were "ds14", "ds15", "ds16", "ds17", and "ds25". https://ftpgeoinfo.msl.mt.gov/Data/Spatial/NonMSDI/Collections/Clark_Fork_Superfund/MTPoleContamination1992.zip http://mslapps.mt.gov/Geographic_Information/Data/DataList/datalist_Details.aspx?did={33b14155-3366-42a0-b50c-1e21d5224fe0} This layer shows areas of contamination originating from the Montana Pole Superfund site in Butte, Montana. The polygons represent areas of surface contaminants, subsurface contaminants, and the area of a subsurface floatin oil LNAPL plume. It also shows which of these areas are unable to be remediated due to the construction of Interstate 90 and shows an area where groundwater was contaminated. The layer was drawn on a 1:2000 scale paper map by Brian Antonioli of the Montana Dept of Health and Environmental Sciences and digitized at the State Library. These data were formerly available from the Montana State Library web site but were removed because they are potentially out of date. Please contact the Federal Superfund Bureau of the Montana Department of Environmental Quality if you want these data so they may tell you if newer or better data are available. If the data are not available from the Department of Environmental Quality, you may request a copy from the Montana State Library data archive. 19921111 Publication Date -112.5637 -112.5463 45.9977 45.9895 ISO 19115 Topic Category environment Contamininatione Montana Pole Montana MT Butte None The Montana State Library provides this product/service for informational purposes only.
