Key Contaminants Detected in Nevada City
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Nevada City's Housing Stock?
With 59% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
What does a median build year of 1987 mean for water safety in Nevada City? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used - making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Nevada City were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Nevada City: Remediation Cost in Perspective
Property equity in Nevada City runs well ahead of estimated remediation costs - a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Nevada City are relatively low compared to home values. The $1,350–$3,900 estimated range is a small fraction of median property value. Home values are 18% below the California average.
Protecting Children from Lead in Nevada City
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 59% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Nevada City.

Historical Flood-Claim Evidence for Nevada City
Historical NFIP data for Nevada City contains 10 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $67,473. Among ZIP codes with claim records, 100% 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. The <strong>$2,500</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
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.
