Key Contaminants Detected in Tenafly
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Tenafly's Housing Stock?
With 77% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing risk in older housing is tied to the period before 1986, when lead pipes and lead solder were still permitted in new plumbing. Tenafly's median build year is 1952, and properties from before that year might still contain lead-bearing joints or pipes. Much of that risk sits inside individual properties, which city-level water quality averages don't capture.
Over half of homes in Tenafly were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Tenafly: Remediation Cost in Perspective
Low tier for Tenafly: remediation estimated at up to 1% of what homes are worth.
Estimated remediation costs in Tenafly can be compared with local home values. The $550–$1,400 estimated range can be set against the median property value; actual costs vary by home. Home values are 101% above the New Jersey average.
Protecting Children from Lead in Tenafly
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Several steps can clarify lead exposure for a Tenafly household. The area figure, an average of ZIP-level 90th-percentile results, is 0.010 mg/L or higher, and the pre-1986 share of local homes is about 77%. The water utility's lead service line inventory shows how a home's service line is classified, a certified laboratory test measures lead at the tap, and a filter certified to NSF/ANSI 53 for lead reduction is an option where results show lead.

Historical Flood-Claim Evidence for Tenafly
Historical NFIP data for Tenafly contains 69 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $20,707. Among ZIP codes with claim records, 0% 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 $900 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.

What You Can Do in Tenafly
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. For Lead and Copper Rule, listed in the water-quality records for Tenafly: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. With 77% of homes built before 1986, lead solder is a real possibility.
