Soil lead contamination disproportionately impacts low-income communities of colour
Soil lead contamination is a pressing issue in Santa Ana, California, and it disproportionately affects low-income communities of colour. Santa Ana, the predominantly Latino county seat of Orange County, has taken steps to address this issue by approving a resolution that addresses both the climate emergency and lead exposure. This resolution aims to limit or prevent lead exposure among its population of over 300,000 people, and it has been praised as a potential model for other cities to follow.
The issue of soil lead contamination in Santa Ana is not new. Studies have shown that the contamination is linked to car pollution from over 100 years ago, specifically from leaded gasoline and lead-based paint. Additionally, historical vehicle emissions have been strongly correlated with lead concentrations in the soil, particularly in urban, disadvantaged neighbourhoods. The California Office of Environmental Health Hazard Assessment has recognised the danger of lead contamination and lowered the soil lead risk standard to 80ppm in 2009. However, the state has failed to enforce this standard or adequately enforce lead testing, leaving low-income communities of colour at high risk of lead exposure and poisoning.
Several factors contribute to the disproportionate impact of soil lead contamination on low-income communities of colour in Santa Ana. Firstly, minority populations often live in more contaminated environments due to systemic oppression and poor city management of general funds. Additionally, housing plays a significant role, as children living in older homes or neighbourhoods with a high proportion of pre-1950 housing are more likely to be exposed to lead. This is because these homes were painted with high concentrations of lead-containing paint, which still persists today.
The City of Santa Ana is taking steps to address the issue of lead contamination. They are working with the County's Health Care Agency and Azure Community Development to offer lead testing and abatement programs for Santa Ana households. However, there is still a lack of adequate lead testing and monitoring, leaving residents at risk of exposure to lead levels exceeding state and federal guidelines.
To effectively address soil lead contamination in Santa Ana and protect vulnerable communities, a combination of policy initiatives, increased funding, improved testing and monitoring, and remediation efforts are necessary. By prioritizing this issue and working collaboratively, the city can mitigate the health risks associated with lead exposure and create a healthier environment for all its residents.

Santa Ana's contaminated soil is linked to car pollution from 100 years ago
Santa Ana, California, is facing a public health crisis due to soil lead contamination, which predominantly affects marginalized communities of colour and lower-income groups. The city has declared a climate emergency and pledged to protect its residents from lead contamination by limiting or preventing exposure to lead and other environmental toxins.
Historical mapping and studies by researchers at the University of California, Irvine (UCI) have revealed that Santa Ana's contaminated soil is linked to car pollution from 100 years ago. UCI researchers analyzed historical data, including maps and newspapers, to understand the sources of soil-lead contamination. They identified two potential sources of lead: lead-based paint and leaded gasoline, with the latter being far more prevalent in Santa Ana.
The studies found a strong correlation between lead concentrations in the soil and historical vehicle emissions, particularly in urban, disadvantaged neighborhoods. This correlation was especially evident around the historic downtown area of Santa Ana, which has experienced higher traffic volumes over the years. The path of the historical roadways in Santa Ana remains largely unchanged, contributing to the persistence of lead contamination in the soil.
To address this issue, the City of Santa Ana is working with the County's Health Care Agency and their contractor, Azure Community Development, to offer lead testing and abatement programs for Santa Ana households. Additionally, organizations like Orange County Environmental Justice (OCEJ) are advocating for annual blood and soil lead testing, remediation treatment, healthcare access, and tenant rights to support the impacted communities.
The resolution passed by the Santa Ana City Council has received praise for addressing environmental justice and acknowledging the intersection of climate change and legacy pollution.

Santa Ana has pledged to limit or prevent exposure to lead
Santa Ana, California, has pledged to limit or prevent exposure to lead among its population of over 300,000 people. The city council approved a resolution that addresses the climate emergency and simultaneously tackles lead exposure and other environmental toxins. The resolution ensures that initiatives to combat the climate crisis are coupled with policies to address economic inequalities, environmental injustices, and public health risks in vulnerable communities.
Santa Ana is facing a soil lead contamination crisis, particularly affecting lower-income communities and communities of color. Research conducted by the Orange County Environmental Justice (OCEJ) and the University of California, Irvine (UCI) found that soil lead contamination is disproportionately impacting marginalized communities. The coalition analyzed over 1,500 soil samples, with results ranging from 11.4 to 2,687 parts per million (ppm), far exceeding safe levels.
The California Office of Environmental Health Hazard Assessment has set a soil lead risk standard of 80 ppm in residential areas, considering anything above this level hazardous to health. However, about half of the soil samples in Santa Ana exceeded this recommendation. The high levels of lead in the soil have been attributed to historical vehicle emissions and the use of lead-based paint and leaded gasoline in the past.
To address the lead contamination issue, Santa Ana is working with the County's Health Care Agency and Azure Community Development to offer a lead testing and abatement program for Santa Ana households. The city's General Plan is also being updated to include an Environmental Justice Policy Framework that prioritizes reducing the community's exposure to pollution, including lead-based paint hazards. Additionally, Santa Ana has applied for federal funding to address the hazards posed by lead-based paint.
By pledging to limit or prevent lead exposure, Santa Ana acknowledges the health risks associated with lead contamination and is taking steps to protect the well-being of its residents, especially in vulnerable communities.

Santa Ana is offering a lead testing and abatement program for households
Santa Ana, California, is facing a soil lead contamination crisis, with research showing that the contamination is disproportionately affecting low-income communities of colour. In response, the City of Santa Ana is offering a lead testing and abatement program for households in partnership with the County's Health Care Agency and their selected contractor, Azure Community Development.
The program aims to address the issue of lead contamination in the city, which has been linked to car pollution from over 100 years ago, specifically leaded gasoline and lead-based paint. The California Office of Environmental Health Hazard Assessment has set a soil lead risk standard of 80ppm, and about half of the soil samples in Santa Ana exceeded this recommendation. The presence of lead in the soil poses a significant health risk to residents, especially children, who can develop neurological issues, and adults, who can suffer from cardiovascular issues, renal problems, and cognitive deficiencies.
The lead testing and abatement program will work to identify households with lead contamination and provide solutions to mitigate the issue. The City of Santa Ana has also declared a climate emergency and pledged to protect its residents from lead contamination, with a focus on creating a healthier environment and addressing environmental injustices. This includes applying for federal funding to address hazards from lead-based paint and working with community organizations to strengthen local programs that eliminate lead-based paint hazards, particularly in residential buildings within environmental justice area boundaries.
Santa Ana's lead testing and abatement program is a crucial step in addressing the city's lead contamination crisis and ensuring the health and safety of its residents, especially those from vulnerable communities. By offering this program, the city is taking proactive measures to mitigate the impact of lead contamination and create a more equitable and sustainable future for its residents. Households in Santa Ana are encouraged to take advantage of this program to protect themselves and their families from the harmful effects of lead exposure.

Lead exposure can cause health issues in both children and adults
The City of Santa Ana, California, has pledged to limit or prevent exposure to lead among its population of over 300,000 people. This comes as a response to the city's soil lead contamination crisis, which has been linked to car pollution and the use of lead-based paint and leaded gasoline in the past.
The health effects of lead exposure in children include behavioural problems, reduced intelligence, attention span, and educational attainment, as well as anaemia, hypertension, renal impairment, immunotoxicity, and toxicity to the reproductive organs. Very high levels of lead exposure can cause severe damage to the brain and central nervous system, leading to coma, convulsions, and even death. These effects may be permanent, and children who survive severe lead poisoning may be left with permanent intellectual disabilities and behavioural disorders.
Lead exposure also causes long-term harm in adults, increasing the risk of high blood pressure, cardiovascular problems, and kidney damage. Additionally, lead exposure during pregnancy can result in reduced fetal growth and preterm birth.
