Environmental Resources

This page shares State, Federal, and local agencies and organizations' data, reports, and news on environmental topics influencing Santa Ana's environmental quality. Information will continue to be posted as it is made available.

State resources

California Office of Environmental Health Hazard Assessment (OEHHA)

The OEHHA protects and enhances the health of Californians and the State's environment through scientific evaluations that inform, support and guide regulatory and other actions. OEHHA strives for environmental justice by:

  • Identifying communities with high pollution and vulnerability;
  • Identifying who is sensitive to pollution;
  • Informing the public of chemicals that can cause harm; and
  • Assisting CalEPA in their environmental justice efforts.

To learn about the California Communities Environmental Health Screening Tool, click on CalEnviroScreen4.0 to identify census tracks at risk for multiple sources of pollution. All indicators include the most recent available data. One new indicator, the Children's Lead Risk Housing, accounts for possible lead exposures from paint and other sources in or around the home.

Department of Toxic Substances Control (DTSC)

The role of the DTSC is to protect California's people and the environment from the harmful effects of toxic substances by restoring contaminated resources, enforcing hazardous waste laws, reducing hazardous waste generation, and encouraging the manufacture of chemically safer products. They also regulate the generation, handling, treatment, and disposal of hazardous waste in California, and oversee the cleaning of thousands of hazardous waste sites in California including disposal sites and industrial sites that resulted in contamination of soil and groundwater.

Regional Water Quality Board (RWQB)

The State Water Resources Control Board (the State Water Board) was created by the Legislature in 1967.

There are nine Regional Water Quality Control Boards in California. The mission of the Regional Boards is to develop and enforce water quality objectives and implementation plans that will best protect the beneficial uses of the State's waters, recognizing local differences in climate, topography, geology, and hydrology. The City of Santa Ana is within the Region 8 Santa Ana Regional Water Quality Board< boundaries (Orange, Riverside, and San Bernardino Counties) and includes nearly 3,000 square miles and a population of almost five million people.

RWQB Project Location Database identifies sites that impact, or have the potential to impact water quality in California, with emphasis on groundwater:


South Coast Air Quality Management District (SCAQMD)

South Coast AQMD is the regulatory agency responsible for improving air quality for large areas of Los Angeles, Orange County, Riverside, and San Bernardino counties, including the Coachella Valley.  The region is home to more than 17 million people–about half the population of the entire state of California.

To report a complaint about excessive odors, smoke, dust, or other contaminants: http://www.aqmd.gov/home/air-quality/complaints

The F.I.N.D  application provides access to consolidated public information about regulated facilities. This information includes facility details, equipment lists, compliance history, reported emissions, and hearing board case details: http://www.aqmd.gov/nav/FIND/how-to-search

Orange County resources

Orange County Water District (OCWD)

The Orange County Water District is responsible for managing the vast groundwater basin that provides most of northern and central Orange County’s drinking water. As part of its groundwater management, OCWD maintains one of the world’s most advanced aquifer recharge systems to replace the water that is pumped from a variety of wells.

South Basin Groundwater Remedial Investigation and Feasibility Study focuses on a two-square-mile portion of the groundwater aquifer located under Irvine, Santa Ana and Tustin. The draft South Basin Feasibility Study (FS) report was recently posted for Stakeholder Advisory Group (SAG) review. The OCWD extended the review period making the total review period 90 days from submittal of the draft FS report for SAG review. Thus, the due date for OCWD to receive comments on the draft Feasibility Study (FS) report is July 6, 2022.

Orange County Health Care Agency (HCA)

The OC Health Care Agency serves the entire county and is charged with protecting and promoting individual, family, and community through a variety of service areas; most of which are preventive in nature. The HCA's mission is in partnership with community, to deliver sustainable and responsive services that promote population health and equity.

The HCA's ability to meet this mission will continue to include community collaboratives such as the Santa Ana Lead in Soil Roundtable and the Childhood Lead Poisoning Preventive Program, whose aims are to reduce lead exposure in soil, dust, paint, and water where families live, work, and play. Even small amounts of lead can harm a child's health. Click here to learn more about making your home lead-safe for your child. The only way to know if your child has lead poisoning is for your child to get tested for lead. As your child's doctor about a blood lead test. Many children at risk for lead poisoning have not been tested. For more information, call (714) 567-6220 or visit www.ochealthinfo.com/lead.

Orange County Environmental Justice (OCEJ)

OCEJ is a multi-cultural, multi-ethnic environmental justice organization. Their mission is to advance environmental justice by mobilizing and empowering marginalized community members. In 2018, OCEJ partnered with the University of California, Irvine Department of Public Health, UCI Community Resilience, and Jovenes Cultivando Cambios (Youth Cultivating Changes) to collect soil samples in Santa Ana to identify areas of lead contamination. In addition, OCEJ has been collaborating with the City of Santa Ana to address environmental justice and lead contamination through the City's General Plan update, the City's long-term planning document.

Local resources

Madison Park Neighborhood Association (MPNA)

MPNA is a grassroots, resident-driven, non-profit organization established in 1987 and works to promote health, education, and quality of life among the residents of the Madison Park neighborhood in southeast Santa Ana. With the support of the California Air Resources Board, South Coast Air Quality Management District, and NASA Citizen Science, MPNA received air monitors to measure pollution levels within their neighborhood. MPNA leaders have also been working with the City of Santa Ana to address environmental justice and environmental health through the City's General Plan update process.
