Housing & Infrastructure in Brunswick
With 48% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Prohibited from residential plumbing since 1986, lead solder divides Brunswick's housing stock along a timeline that the median build year of 1985 straddles. A meaningful share of homes predates the ban — a configuration that places moderate aggregate pressure on plumbing-related lead risk, distributed unevenly across neighborhoods.
Most homes in Brunswick were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Brunswick Homeowners
When estimated remediation is placed alongside median property values in Brunswick, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Brunswick are relatively low compared to home values. The $870–$2,100 estimated range is a small fraction of median property value. Home values are 10% below the Georgia average.
Lead Exposure Risk for Children in Brunswick
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 48% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Brunswick.

Flood & Climate Risk in Brunswick
NFIP data for Brunswick documents 1082 flood insurance claims across the program's multi-decade tracking period, with 60% of ZIP codes mapped into FEMA flood zones. That level of exposure creates compounding risk during major flood events: treatment systems can be overwhelmed, wells can be contaminated, and distribution infrastructure can suffer backflow — all pathways by which flood events degrade local water quality beyond the physical damage.
Brunswick has a significant flood history with 1,082 FEMA flood insurance claims on record, averaging $22,842 per claim. With 60% 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>$1,380</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.
