Soil Testing in Pasadena Parks: 5 Urgent Facts on Lead Risks

1. Five Urgent Facts About Lead Risks: Soil Testing in Pasadena Parks

Soil testing in Pasadena parks is more than a local concern—it’s a crucial public health initiative impacting residents, families, and youth athletes across Pasadena and Los Angeles County. Recent events, particularly after the Eaton Fire, have revealed disturbing lead levels in Pasadena soil. Infields at Washington Park and Victory Park are currently closed, as soil sampling found lead levels above 80 parts per million in some areas. While cleanup thresholds were not reached, these findings require urgent evaluation, ongoing monitoring, and, where necessary, targeted remediation.

Let’s break down the five most urgent facts everyone in Pasadena, Los Angeles County, and neighborhoods along Washington Boulevard, North Altadena Drive, Lincoln Avenue, Orange Grove Boulevard, and Eaton Drive needs to know:

1. Lead is widespread in public park soil—even in open, recreational areas. Any area with exposed soil, especially infields, baseball diamonds, soccer fields, and track or football fields, must be evaluated for heavy metals contamination.
2. Los Angeles County soil sampling has shown that soil lead levels can exceed the EPA’s safety limit of 40 mg/kg (ppm) for play areas, with Pasadena park soil sometimes measuring more than 80 ppm, and worst patches reaching four times the EPA safe limit.
3. Health risks of heavy metals in soil are especially serious for children, who are more susceptible to the toxic effects of lead, as well as for the broader community.
4. Neighborhood soil evaluation in Pasadena is ongoing, with exposed infields in key parks closed off and residents redirected to turf fields for safety until further testing and possible remediation are completed.
5. Public park soil remediation is a community-wide necessity. Timely action is needed not just in the highlighted areas but in parks, schools, community centers, and sports fields citywide, especially after environmental disasters like wildfires, which exacerbate contamination risks.

Soil contamination in Los Angeles County is not isolated to a particular street, avenue, or boulevard. In Pasadena, neighborhood soil evaluation and ongoing public park soil remediation are essential for community health, sustainability, and environmental protection.

2. Why Soil Testing in Pasadena Parks is Critical for Public Health

Regular soil testing in Pasadena parks is not just a bureaucratic procedure; it’s a science-based approach to protect our children and our environment. The recent findings from Los Angeles County soil sampling after the Eaton Fire are a stark reminder that urban parks, recreational fields, and open spaces face ongoing threats from heavy metals.

Let’s look at what prompted the urgent evaluation and closures:

• Washington Park Infields and Victory Park Infields: Both closed after elevated lead levels (over 80 ppm) were discovered.
• Two Key Neighborhoods (as announced by Pasadena officials):
  • Bounded by Lincoln Avenue, Washington Boulevard, North Altadena Drive, and the city limit
  • Bounded by North Altadena Drive, Orange Grove Boulevard, Washington Boulevard, and Eaton Drive

  Soil in these areas is under urgent review, and parks with exposed soil are being evaluated for safety.

If you have children, you may already know how quickly they come into contact with bare soil—at playgrounds, baseball diamonds, and parks throughout Pasadena and Los Angeles County. Given ongoing concerns, the city strongly encourages heavy metals tests and professional evaluation at all sports fields and youth play areas within these neighborhoods. Early and regular soil evaluation is the first line of defense against potential health risks.

3. Lead Levels in Pasadena Soil: What the Los Angeles County Soil Sampling Reveals

The Los Angeles County soil sampling effort in Pasadena has focused attention on the frequency and distribution of dangerous lead levels in soil—especially at parks, baseball fields, and recreational spaces most frequented by children. Here are the key locations and findings driving new policies in soil testing:

• Washington Park and Victory Park: Detected lead levels over 80 ppm, above the CDC’s recommended “safe” guideline of 40 ppm for play areas.
• Neighborhoods affected:
  • Lincoln Avenue, Washington Boulevard, North Altadena Drive, and the city limit
  • North Altadena Drive, Orange Grove Boulevard, Washington Boulevard, and Eaton Drive
• Robinson Park, Hamilton Park, and Alice’s Dog Park are outside the immediately identified neighborhoods and remain open, but with precautionary soil sampling and monitoring planned.

It’s critical to remember that lead “parts per million in soil” doesn’t always require direct remediation (EPA’s cleanup trigger: 400 ppm in play areas, 1200 ppm in non-play areas), but any elevation calls for ongoing evaluation, monitoring, and protective measures.

• Residents and sports participants are being redirected to turf and artificial fields where possible.
• Park closures due to soil contamination underscore the importance of sports field soil safety and swift, science-based action.

What Triggers Soil Contamination in Los Angeles County Parks?

Across Pasadena and the broader Los Angeles County, soil can become contaminated through several avenues:

• Historical use of leaded gasoline and industrial activity
• Atmospheric deposition from past emissions or nearby traffic corridors (Lincoln Avenue, Washington Boulevard, Orange Grove Boulevard)
• Aftermath of wildfires like the Eaton Fire, which can re-mobilize heavy metals previously sequestered in vegetation or topsoil

These overlapping sources necessitate a multi-tiered approach to soil safety, combining regular residential, neighborhood, and city-run park soil tests.

Why “Parts Per Million” Matters in Park Soil Safety

The metric “parts per million” (ppm) in soil is the standard for determining safe versus hazardous contamination levels. For lead, the risk increases with prolonged exposure above 40 ppm (the CDC recommendations for play areas), with more severe risks above 400 ppm.
However, even low-level chronic exposure—especially through soil dust that can be ingested or inhaled by children—poses neurological and developmental risks.

4. Health Risks of Heavy Metals in Soil: The Community Impact

Consistent soil evaluation and remediation in public parks are vital due to the severe and long-lasting health effects of lead exposure, especially on children, pregnant women, and those with compromised immune systems.

• Children’s Health Risks: Lowered IQ, learning disabilities, attention deficits, behavioral issues.
• Adults’ Health Risks: Increased blood pressure, reproductive problems, kidney and nervous system damage.
• General Population Risks (from ongoing exposure): Community-wide impacts through accumulation in the food chain and contamination of home gardens.

Areas most at risk often include infields, playgrounds, and bare soil patches where residents engage in baseball, soccer, football, or athletics—precisely the fields and parks under urgent review in Pasadena.

What Other Heavy Metals Are Monitored?

Apart from lead, the soil sampling in Pasadena parks may check for:

• Cadmium
• Arsenic
• Mercury
• Chromium

However, lead remains the most prevalent and concerning contaminant in public park settings.

By prioritizing sports field soil safety, Pasadena is setting a model for other Los Angeles County neighborhoods.

Protecting Our Most Vulnerable: Parks, Infields, and Sports Fields

• Young athletes in baseball diamonds, soccer fields, and football/track zones often experience the greatest exposure due to frequent contact with bare or dusty soil.
• By closing contaminated fields, redirecting teams to turf, and funding further testing, Pasadena is reducing these risks—demonstrating sustainability and community responsibility.

5. Park Closures Due to Soil Contamination and Remediation Steps

Public trust in our parks and recreational fields depends on quick, transparent, and effective action when contamination is found. Pasadena’s response aligns with best practices for public park soil remediation and sports field soil safety.

1. Immediate Park Closures: Infields at Washington Park and Victory Park are closed to public use while further testing is conducted.
2. Redirection to Turf Fields: Residents and youth sports groups are being redirected to safer, artificial turf fields while remediation or evaluation is underway.
3. Precautionary Evaluation: Outside the high-risk neighborhoods (Robinson Park, Hamilton Park, Alice’s Dog Park), open status remains, though exposed soil will be sampled as a precaution.
4. Comprehensive Soil Testing Required: The City of Pasadena strongly encourages soil testing at all parks and sports areas with exposed soil, not limited to the two highlighted neighborhoods. All areas must be closed to public use until heavy metals testing is complete.
5. Ongoing Communication and Transparency: Results of ongoing soil sampling and evaluation will be shared with the public to ensure trust and rapid response as needed.
