Key Contaminants Detected in Long Valley
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Long Valley's Housing Stock?
With 66% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Long Valley's median build year of 1971 places it squarely in that category.
Over half of homes in Long Valley were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Long Valley: Remediation Cost in Perspective
Across Long Valley, the equity share taken up by estimated remediation is small - a favorable ratio for most property owners.
Remediation costs in Long Valley are relatively low compared to home values. The $1,200–$2,600 estimated range is a small fraction of median property value. Home values are 24% above the New Jersey average.
Protecting Children from Lead in Long Valley
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.
When older housing represents 66% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Long Valley address.

Historical Flood-Claim Evidence for Long Valley
Historical NFIP data for Long Valley contains 100 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $24,907. 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>$1,800</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.
