Housing Age Profile

A citywide median of 1995 for construction says little about any single address in Myrtle Beach. 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 Myrtle Beach were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

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.

For families with young children in Myrtle Beach, two area figures are available: pre-1986 construction at about 30%, and a mean of the ZIP codes' 90th-percentile lead results under 0.010 mg/L. Testing water from the tap a child drinks from gives a home-specific result.

Myrtle Beach: NFIP Claim Records and Water-Quality Context

Total FEMA Flood Claims

Avg Reported Sum With Payment Data

43%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Myrtle Beach contains 4,092 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $42,370. Among ZIP codes with claim records, 43% 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 $580 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.
