WHAT (& WHAT FOR): PFOAS are a group of large manufactured chemicals that are widely used in various everyday items. Often used in waterproof items and nonstick pans among other products. They are used in a number of industrial processes. Improper disposal of the chemicals from industrial manufacturing has resulted in PFAS seeping down into the ground and into the water supply. These chemicals are known to be forever chemicals that do not degrade in the environment.
HEALTH IMPACT: PFAS are known to be forever chemicals that cause weakened immune systems, increased cholesterol level, increased risk of testicular and kidney cancers, and decreased vaccine response in children. EPA has concluded that exposure to PFOA and PFOS over certain levels may result in developmental effects to fetuses during pregnancy (low birth weight) or breastfed infants (accelerated puberty, skeletal variations).
LOCAL IMPACT: Both the State Water Board and the Santa Ana Water Board have initiated investigations. The PFAS investigation done by State of California Regional Water Quality Control Board reveals results that show PFAS concentrations above the current Notification Levels for drinking water. Santa Ana Water Board staff is currently working to identify potential sources of the contamination in the groundwater.
POSSIBLE RESPONSES:
Conduct wellhead treatment to treat PFAS impacted drinking water to levels below state-established PFOA/PFOS notification levels.
Obtain a more comprehensive monitoring information on potential sources of PFAS
Set Effluent guidelines, develop analytical methods and issue water quality criteria for PFAS
