SCV Water Moves Forward with Testing Water Treatment to Remove PFAS by Kathie Martin Jul 12, 2019 Member Submitted News The SCV Water Board of Directors approved expedited testing of treatment options for per- and polyfluoroalkyl substances (PFAS), which were recently found in groundwater in SCV’s service area. This proactive measure is in response to the State Water Resources Control Board – Division of Drinking Water’s (DDW) interim notification and response level monitoring requirements. “We are dedicated to maintaining water quality that meets all standards,” said SCV Water’s General Manager Matt Stone. “Taking immediate action to expedite testing will not only help us determine the best long-term technology to remove PFAS from our groundwater supply, but will also provide us with information needed by DDW to permit the treatment system in the future.” SCV Water has selected Water Quality & Treatment Solutions, Inc. to provide expedited bench-scale testing of PFAS treatment options. The study will focus on two treatment options, running water collected from affected wells through both granular activated carbon adsorption and synthetic ion-exchange adsorption processes. SCV Water is one of 200 plus water systems with more than 612 groundwater wells in California required to sample for PFAS chemicals. So far, SCV Water has sampled 14 wells for PFAS this year. Of the wells tested, eight were above the interim notification levels. One exceeded the response level and was immediately removed from service. Per- and polyfluoroalkyl substances (PFAS) are a group of manmade chemicals that are prevalent in the environment and were commonly used in industrial and consumer products to repel grease, moisture, oil, water and stains. These chemicals enter the environment through treated wastewater discharges, landfills and areas where the substances were used outdoors. “Our customers come first, and we continue to vigilantly monitor our water quality and implement new strategies as needed to safeguard our water supply,” noted Stone. “SCV Water has set up a team dedicated to developing a pre-emptive plan to address all aspects of the emerging PFAS issue, and we remain committed to transparently share up-to-date information on this topic with our customers.” For more information and resources on PFAS, visit yourSCVwater.com/pfas.
