Ecology seeks your input on the draft Remedial Investigation and Feasibility Study for the Warden City Water Supply Wells 4 & 5 site. The RI documents the extent and locations of ethylene dibromide (EDB) contamination in soil and groundwater at the site. The FS evaluates cleanup options.
From 1971 to 1992, Simplot stored, blended, and transported agricultural chemicals, including EDB, at the site. After the City of Warden discovered EDB in wells 4 and 5, they started using wells 6 and 7. Soil at the Simplot property was found to contain EDB at levels that are a potential risk for groundwater contamination and consistent with EDB levels in groundwater.
