Housing & Infrastructure in Conway
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
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Conway, the median build year of 1995 indicates that plumbing age is a material factor in local lead risk — with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Conway were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Conway Homeowners
The equity-to-remediation ratio in Conway is moderate — worth planning for but within reach for most property owners.
Remediation costs are moderate relative to home values in Conway. The estimated $1,633–$4,300 range is manageable for most homeowners but still worth budgeting for. Home values are 13% above the South Carolina average.
Lead Exposure Risk for Children in Conway
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 35% of Conway stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.

Flood & Climate Risk in Conway
Conway's flood profile — 1334 NFIP claims over the program's multi-decade period and 100% of ZIP codes within FEMA-designated flood zones — reflects a community where flooding has shaped the local risk landscape in sustained ways. That sustained exposure has specific consequences for water quality that don't apply to lower-exposure areas. Treatment facilities handling intake from flood-saturated watersheds face contaminant loads that can exceed normal filtration capacity. Private wells in FEMA-designated zones face surface infiltration risk during every significant event. Distribution systems in areas that flood repeatedly accumulate backflow stress over time. None of these represent constant threats to water quality, but they are activated by the kinds of events that the NFIP record shows have occurred here, repeatedly, over many years.
Conway has a significant flood history with 1,334 FEMA flood insurance claims on record, averaging $31,433 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>$2,600</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.
