Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Myrtle Beach Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Myrtle Beach's residential inventory spans multiple construction eras, with the median build year of 1995 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints — a plumbing practice banned that year — while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
Most homes in Myrtle Beach were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Myrtle Beach
Setting Myrtle Beach remediation figures against its property market, the resulting ratio sits comfortably in the low tier — a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.

Myrtle Beach: Lead Risk & Vulnerable Populations
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.
Through the multi-year window of EPA Lead and Copper Rule monitoring, Myrtle Beach has stayed under the action mark. Paired with a 30% pre-rule housing share, the result places lead in a lower-priority spot on the local picture — without erasing the structural gap between citywide averages and what arrives at one specific tap.

A claim count of 4091 in the NFIP database — alongside 100% of ZIP codes in FEMA-designated flood zones — points to something data alone can only partly convey: a community that has repeatedly dealt with the full consequences of significant flooding. Treatment plants overwhelmed by floodwater, private wells compromised by surface infiltration, and distribution systems stressed by pressure events are all downstream effects of the flood history Myrtle Beach's NFIP record documents.
Myrtle Beach has a significant flood history with 4,091 FEMA flood insurance claims on record, averaging $27,789 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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. Flood damage can add significantly to the estimated <strong>$2,157</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
