Although much of Reno meets baseline drinking water standards, some NV-tracked service areas show violations that merit a closer look - particularly for older housing stock.

Top Contaminants

Lead Risk

What Reno Residents Can Do

Test Your Water

• Order a certified lab test - home test kits cost $20–50 and cover lead, bacteria, and common contaminants
• Request your utility's CCR (Consumer Confidence Report) - your water provider must publish this annually
• Check your ZIP code - each area in Reno has different water systems and risk levels

Filter Your Water

• NSF-certified pitcher filter removes chlorine taste and some contaminants ($20–40)
• NSF 53-certified filter for lead - recommended for homes built before 1986
• Reverse osmosis system removes 95%+ of contaminants including lead, PFAS, and nitrates ($150–400)

Test for Radon

• Reno is in a moderate-risk radon area
• Short-term radon test kits cost $10–25
• If levels exceed 4 pCi/L, EPA recommends professional mitigation

Stay Informed

• Visit your ZIP code report for detailed, address-level data
• Sign up for EPA water quality alerts
• Review the annual water quality report from your local utility

Housing Age Profile

For most of Reno's housing stock, construction occurred after 1986 - when lead solder in plumbing was federally prohibited. The median build year of 1991 broadly reflects that newer profile.

Most homes in Reno were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Reno: Lead Risk & Vulnerable Populations

0.0004

mg/L Avg Lead (Limit: 0.015)

Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Lead risk in Reno appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Reno contains 462 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $35,293. Among ZIP codes with claim records, 50% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
