Housing & Infrastructure in Henderson
With 49% 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.

Housing Age Profile
A citywide median of 1983 for construction says little about any single address in Henderson. Homes built before 1986, when federal amendments restricted the lead content allowed in new pipe, solder and flux, may contain plumbing materials with more lead, and later renovations may have replaced them. An inspection of the plumbing can identify the materials, and sending a tap water sample to an accredited laboratory measures lead.
Most homes in Henderson 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 Henderson Homeowners
Estimated remediation for Henderson is a small fraction of median property value - one percent or less - though the ratio does not describe any single household.
Estimated remediation costs in Henderson can be compared with local home values. The $150–$600 estimated range can be set against the median property value; actual costs vary by home. Home values are 39% below the Maryland average.
Lead Exposure Risk for Children in Henderson
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 Henderson
Historical NFIP data for Henderson contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $38,557. 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 $300 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.
