The fastest growing Horizontal Remediation Well Applications are Bio Sparge and Air Sparging Wells. Bio Sparge and Air Sparging Wells have earned the designation of workhorses due to their consistent ability to trod forward. Consultants that have used these Horizontal…
A 1000-gallon trichloroethylene (TCE) spill created an 800-foot long, narrow plume in saprolite and weathered bedrock that embodies the classic heterogeneity challenges to insitu remediation. Gravity drove the dense, non-aqueous liquid (DNAPL) 120 feet downward at varying rates, producing a vertical…
