Housing Age Profile
For a household in Holmdel, a certified lab test of tap water answers what the median build year of 1982 cannot.
Most homes in Holmdel were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Holmdel Homeowners
Because the median home value in Holmdel is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in Holmdel can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 68% above the New Jersey average.
Lead Exposure Risk for Children in Holmdel
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Holmdel
Historical NFIP data for Holmdel contains 14 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $30,122. 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 $500 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 Holmdel
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Lead and Copper Rule, listed in the water-quality records for Holmdel: 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 47% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
