Remediation Injection

EPS was contracted by a Colorado consulting firm to inject ORC at a site near Rush Center, Kansas. The ORC was utilized to create barrier walls within the aquifer where petroleum related contamination was known to be migrating toward public water supply wells. The ORC was injected at different intervals within each testhole utilzing a pressure grout pump. The ORC was injected near the base of the aquifer (60-70 ft.) and near the water table surface (20-30 ft. bgs). Several monitoring wells that were previously installed at the site are currently being monitored to determine the remedial effect of the ORC-induced aquifer. EPS was contracted by a Wichita, Ks. consulting firm to inject ORC at a State Trust Fund site in Hutchinson, Kansas. The ORC was injected within the top ten feet of the aquifer (19-29 ft), and was utilized to create a barrier wall within the aquifer where petroleum related contamination was known to be migrating toward domestic wells. EPS was contracted by a Kansas City consulting firm to inject ORC at a State Trust Fund site in Newton, Kansas. The ORC was injected from the bedrock surface to the top of the aquifer, and was again utilized to create a barrier wall within the aquifer where petroleum related contamination was known to be migrating toward domestic wells. Additional ORC injection is pending dependent on analytical results obtained from surrounding monitoring wells. EPS was contracted by a Paola, Ks. consulting firm to inject ORC at a State Trust Fund site in Park City, Kansas. The ORC was injected within the top ten feet of the aquifer (17-27 ft), and was utilized to create a barrier wall within the aquifer where petroleum related contamination was known to be migrating toward public supply wells. EPS was contracted by an Omaha, Nebraska consulting firm to inject ORC at a site in Council Bluffs, Iowa. The ORC was injected within the groundwater adjacent to a lake, where underground petroleum storage tanks had had leaked. The ORC was injected in two cycles, and contaminant levels have dropped considerably within the past year. EPS was contracted by a Kansas City, Missouri consulting firm to inject potassium manganate at Fort Riley, Kansas as part of a former dry cleaning remediation project. EPS was contracted by a Kansas City, Missouri consulting firm to inject edible oil at a site in Manhattan, Kansas. Injections points were determined by field gc screening results supplied by EPS from rounds of groundwater sampling. Contamination impact is reflected and continues to be periodically monitored and injections scheduled accordingly.
