ESI returned a winning lump sum to closure bid of $1.85 million. The then previous consultant’s lump sum bid was $30 million.
ESI then negotiated substantial modifications to the Consent Decree with the State of Kansas. The cap was removed and over 7,000 old product and waste drums were discovered and removed for disposal.
Contaminated soils were land-farmed on-site until they met Kansas soil standards allowing on-site re-use. A facility building project was allowed to make use of the formally capped area.
ESI modified the pump & treat system for better source area capture and installed a pulsed air sparge system to greatly reduce groundwater remediation time and expense. Fenton Reagent and nutrient injection to encourage chemical oxidation and bioremediation are augmenting the air sparge system.
