Lead Hazard

WHAT (& WHAT FOR): Lead is a metal often found in pipes, and in old paint (before it was banned in paint in the late 1970s). Before 1996, lead also found in vehicle fuel resulting in  soil contamination in many communities from both paint dust and vehicle pollution. 

HEALTH IMPACT: Lead is a neurotoxin and is known to have no safe blood lead level in children. 

Has been linked to:

  1. Brain swelling, anemia, seizures, renal failure, reduced IQ, and ADHD

  2. Damages brain development in children

  3. Connected to behavioral problems like aggression and bullying, and internalizing problems such as depression and anxiety 

LOCAL IMPACT: Recent research in Santa Ana has shown that there is a disproportionately impact of solid lead contamination crisis on lower income, people of color communities. 

POSSIBLE RESPONSES: There are many ways to respond to lead contamination:

  1. Providing special health care for children with high blood lead levels, and investigating possible sources of lead exposure in homes, daycares and school, playground, etc.

  2. Implement strict housing policies where landlord and city housing officials are required to have lead inspections of homes for lead paint hazards (especially in low income, people of color communities)

  3. Requiring a minimum reduction standard for lead paint in older homes 

  4. Requiring blood lead level test as part of the routine check up for children (extremely important for children in low-income housing)

PFAS Hazard

In response to

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: 

  1. Conduct wellhead treatment to treat PFAS impacted drinking water to levels below state-established PFOA/PFOS notification levels.

  2.  Obtain a more comprehensive monitoring information on potential sources of PFAS

  3. Set Effluent guidelines, develop analytical methods and issue water quality criteria for PFAS
