Municipal drinking water treatment
Municipalities are often faced with VOC contamination of their source wells. Chemicals like Vinyl Chloride and Trichloroethylene can leach into aquifers used as source water for municipal wells. When this occurs, in many cases the most cost-effective solution is to treat the water to remove the VOCs using air stripping, which has been established as a Best Available Control Technology BACT for this application.

Orange County Water District Removes PFAS With 30 Systems
In February 2020, the California State Water Resources Control Board announced revised drinking water Response Levels for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water. The new Response Levels (RLs) were set at 10 parts per trillion (ppt) for PFOA and 40 ppt for PFOS. The previous RL was 70 ppt for a combined total concentration for the two contaminants.

Ion exchange services remove groundwater contaminants
California Water Service Company had acquired another water company with approximately 100 connections, in Porterville, California, located in a remote agricultural area of the Central Valley. Their annual well testing had shown levels of nitrate at or near the Maximum Contamination Level (MCL) of 45 ppm and perchlorate was found in the groundwater at levels above the Public Health Goal (PHG) of 10 ppb. A treatment system was needed to remove both these contaminants to ensure quality potable water for the local community.
