The State Water Resources Control Board (SWRCB) has sent hundreds of Investigative Orders this week to various entities to assess Per- and polyfluoroalkyl substances (PFAS) chemicals in soil and groundwater. Hundreds more are planned.
Are you familiar with PFAS chemicals? They are used extensively in industry because of their resistant to heat, water, and oil. The PFAS chemicals include PFOA, PFOS, GenX, and many others. PFAS are manufactured and used in a variety of industries, including commonly used products, such as carpeting, clothing, upholstery, food paper wrappings, fire-fighting foams, and metal plating. PFOA and PFOS have been the most extensively produced and studied of these chemicals. They don’t break down and they can accumulate over time in the human body and the environment. There is evidence that exposure to PFAS can lead to adverse human health effects (EPA.gov).
On February 14, 2019, the profile of PFAS chemicals was raised significantly when the US Environmental Protection Agency (EPA) announced they are moving forward with a drinking water Maximum Contaminant Level (MCL) for PFOA and PFOS. EPA is also gathering and evaluating information to determine if regulations are appropriate for a broader class of PFAS.
On March 6, 2019, the SWRCB held a workshop regarding PFAS and the path moving forward in California. In this workshop, they announced three phases of investigation were being implemented immediately.
Phase I, now in process, includes issuing:
The California 13267 Orders require (in general) the submittal of:
Alta Environmental has confirmation of this, as one of our clients has already received an Order.
Phase II, scheduled for fall 2019, will include source investigation and nearby drinking water well sampling at:
Phase III, also scheduled for fall 2019, will include source investigation and nearby drinking water well sampling at:
Do you fall into any of these categories? Have you received an Order? If so, Alta can help you respond to the order, implement the investigation, and manage and control your risk. Please contact Mike Cassidy at Alta Environmental for further information or call 562-495-5777.
