Impacted Municipal Water Supply Wells (Central Valley, California)

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 near the end of litigation. Although it did not settle as envisioned by the attorneys, it did result in the recovery of $16M in investigation and remediation costs for the city.

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