Abstract : This interim response action is an upgrade of the treated ground water recharge system associated with the north boundary containment/treatment system. In order to correct an hydraulic imbalance, ten gravel filled recharge trenches were constructed along the downgradient side of the barrier. Water is piped underpressure from the treatment plant through a new effluent pipe to the trenches. This should increase recharge capacity by 150 gallons per minute. The implementation plan includes the following: Mou between the army and shell concerning the north boundary trenches IRA; Scope of work; Construction work plan; Cost estimate - $490,000; Engineering specifications and engineering drawings and schematics.
