Lead Risk Overview
The average of the reported 90th-percentile lead results across the ZIP codes of Nevada is 0.0017 mg/L; the EPA action level of 0.015 mg/L applies to a water system's own 90th-percentile result and is not a safety threshold (EPA's health goal for lead is zero). Out of 111 ZIP codes with lead data, 0 exceed the EPA action level.
Housing Age and Lead Risk
Lead plumbing solder was banned in 1986. In Nevada, approximately 42% 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 42% of housing stock pre-1986, Nevada has above-average risk from aging plumbing infrastructure. Targeted testing and service line replacement are priorities.
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 Nevada:
| Metric | Value |
|---|---|
| FY2025 allotment | $28.6M |
| Additional subsidy | 49% (grants/forgiveness) |
| National total | $3.0B |

Health Effects of Lead Exposure
Lead exposure affects every organ system. Key health risks include:
Children: Developmental delays, reduced IQ, behavioral problems, slowed growth
Adults: Kidney damage, high blood pressure, reproductive issues, nerve disorders
Pregnant women: Lead crosses the placenta and affects fetal development
How to Test for Lead
- Contact your water utility - many offer free lead testing
- Use a certified test kit ($20-$50) from a hardware store
- Hire a certified lab ($150-$400) for comprehensive testing
- Run cold water before drinking after water has sat in the pipes; how long depends on your plumbing and whether you have a lead service line, so ask your utility
- Install a NSF/ANSI 53-certified filter rated for lead removal

Test Your Water for Lead →Frequently Asked Questions
Does Nevada have lead in its drinking water?
The average of the reported 90th-percentile lead results across the ZIP codes of Nevada is 0.0017 mg/L; the EPA action level of 0.015 mg/L applies to each water system's own 90th percentile, not to this average. 0 ZIP codes are mapped to a water system that reported a 90th-percentile lead result above the EPA action level. Lead can enter water through older pipes and service lines even when source water is clean.
How old are homes in Nevada?
Approximately 42% of housing in Nevada was built before 1986, when lead solder was banned in plumbing. Older homes have higher risk of lead contamination from pipes, solder joints, and fixtures.
How much federal funding does Nevada receive for lead pipe replacement?
Nevada receives $28.6M in federal lead service line replacement funding (FY2025) through its Drinking Water State Revolving Fund for lead service line inventory and replacement. 49% is designated for grants or principal forgiveness for disadvantaged communities.
How can I test my water for lead in Nevada?
Ask your local water utility in Nevada whether it offers lead testing and what it costs, especially for homes built before 1986. Certified drinking-water laboratories also test for lead; home screening kits are sold as well, and prices vary.
