In the period between 1982 to 1984 multiple studies on lab rats concluded that inhalation concentrations of ethylene oxide could be correlated to cancer development. An analysis of the results found that increased exposure showed higher incidences of tumor development in both male and female lab rats. According to the EPA EtO is carcinogenic and, “Scientific evidence in humans indicates that exposure to EtO for many years increases the risk of cancers of the white blood cells, including non-Hodgkin lymphoma, myeloma, and lymphocytic leukemia. Studies also show that long-term exposure to EtO increases the risk of breast cancer in women.”
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:
Brain swelling, anemia, seizures, renal failure, reduced IQ, and ADHD
Damages brain development in children
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:
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.
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)
Requiring a minimum reduction standard for lead paint in older homes
Requiring blood lead level test as part of the routine check up for children (extremely important for children in low-income housing)
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
