Dallas Infrastructure Age
Median build year of 1977 means many homes predate lead paint and lead solder regulations. Consider testing if your home has original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Newer construction dominates Dallas's residential inventory, as reflected in a median build year of 1977. The practical implication is that lead-soldered copper plumbing joints - a pre-1986 standard now federally prohibited - are an exception rather than the rule in this city, though they remain present in the older fraction of the housing stock.
Most homes in Dallas were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Dallas: 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.
Lead risk in Dallas appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

Dallas: Flood History & Water Damage Risk
Measured across the NFIP's multi-decade tracking period, Dallas shows a moderate flood record - 1614 claims and 0% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Dallas has a moderate flood history with 1,614 FEMA claims. Flood events can contaminate drinking water and overwhelm treatment systems.
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.
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.
