Impacted Municipal Water Supply Wells (Central Valley, California)

We provided technical support to two municipalities in litigation with PRPs over PCE/TCE contamination of water supply wells; the city's sole source of drinking water. Environmental event reconstruction techniques as well as knowledge of chloroethene fate and transport were used to determine the mechanisms (e.g. direct or sewer release) of contamination.

My involvement in the first case was "late in the game". Although it did not settle as originally envisioned by the attorneys, it resulted in the recovery of $16,000,000 in investigation and remediation costs for the city.

I was involved with the second case earlier on. This was considered a success; the city was awarded a $178,000,000 judgement and was believed to have recovered at least $41,000,000 in remediation and water treatment costs.
