City Of Lodi Employs GAC To Remove Contaminants From Groundwater

Source: AqueoUS Vets

The City of Lodi, located in California’s Central Valley, sources approximately 50 percent of its drinking water from surface water, with the remaining supply pulled from 23 wells throughout the city. In 2018, 1,2,3-trichloropropane (1,2,3-TCP) was discovered in the north and central service area’s groundwater, a man-made, chlorinated hydrocarbon often associated with pesticides and cleaning and degreasing solvents.

According to the California Department of Public Health, granular activated carbon (GAC) is the Best Available Technology (BAT) for the removal of 1,2,3-TCP. The city contracted Deidi Construction, who then partnered with Aqueous Vets® (AV®) as a design build partner. AV supplied the GAC systems, onsite pipe and installation services targeting two wells (27 and 28) for treatment to maintain compliance with state drinking water standards.
