What's in Jefferson Valley's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Jefferson Valley Infrastructure Age
With 100% 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
The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing - from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Jefferson Valley, where the median build year is 1967, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.
Over half of homes in Jefferson Valley were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Jefferson Valley
When estimated remediation is placed alongside median property values in Jefferson Valley, the resulting ratio is low - a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Jefferson Valley are relatively low compared to home values. The $2,000–$4,100 estimated range is a small fraction of median property value. Home values are 8% below the New York average.
Jefferson Valley: Lead Risk & Vulnerable Populations
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.
Wherever 100% of local housing was built before solder rules changed - as is the case in Jefferson Valley - a faucet-level sample closes the gap that aggregate utility data cannot.

Jefferson Valley: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Jefferson Valley contains 6 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $19,381. 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>$3,000</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.
