A Watsonville, Calif.-based contractor and materials supplier has agreed to settle a lawsuit brought by the Santa Clara County District Attorney’s Office for allegedly allowing stormwater contaminated with heavy metals to drain into a creek.
An investigation started in 2017 showed stormwater with high alkalinity passed into storm drains from one Graniterock facility, and runoff with high levels of iron flowed into the drain at another because of lacking and ineffective treatment systems at the two San Jose facilities, according to the district attorney’s office.
