Lead Risk Overview
The average 90th percentile lead level across New Jersey water systems is 0.0033 mg/L - within EPA limits. Out of 551 ZIP codes with lead data, 1 exceed the EPA action level.
Housing Age and Lead Risk
Lead plumbing solder was banned in 1986. In New Jersey, approximately 73% of housing was built before this date, creating elevated risk of lead in residential plumbing.
Lead can enter water through:
- Lead service lines connecting water mains to homes
- Lead solder joints in copper plumbing
- Brass fixtures and faucets containing up to 8% lead (pre-2014)
With 73% of housing stock pre-1986, New Jersey has above-average risk from aging plumbing infrastructure. Targeted testing and service line replacement are priorities.
Children's Blood Lead Levels
CDC surveillance data for children tested in New Jersey:
| Year | Children Tested | BLL >= 5 ug/dL | BLL >= 10 ug/dL |
|---|---|---|---|
| 2017 | 172,524 | 2.2% | 0.5% |
| 2018 | 170,931 | 2.1% | 0.5% |
| 2022 | 154,242 | 1.3% | 0.3% |
The CDC states there is no safe level of lead exposure, particularly for children under 6. Even low levels can cause developmental delays, learning difficulties, and behavioral problems.
LCRI Funding and Service Line Replacement
The EPA's Lead and Copper Rule Improvements (LCRI) require water systems to inventory all service lines and replace lead lines within 10 years.
Federal funding for New Jersey:
| Metric | Value |
|---|---|
| FY2025 allotment | $107.8M |
| Additional subsidy | 49% (grants/forgiveness) |
| National total | $3.0B |
