Key Contaminants Detected in Arlington
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Arlington's Housing Stock?
With 50% 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
The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing — from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Arlington, where the median build year is 1986, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.
Over half of homes in Arlington were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Arlington: Remediation Cost in Perspective
In Arlington, documented water and safety issues can be addressed without making a meaningful dent in home equity — the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Arlington are relatively low compared to home values. The $1,318–$3,100 estimated range is a small fraction of median property value. Home values are 26% above the Texas average.
Protecting Children from Lead in Arlington
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.
Locally, 50% of Arlington homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.

Climate-Related Water Risk for Arlington
Over the multi-decade span covered by the National Flood Insurance Program, Arlington has accumulated 1042 flood claims — a total that reflects a community where significant flooding is a recurring, documented feature of the local environment. That history has direct relevance to water quality. Each major flood event activates contamination pathways that are absent or dormant during dry conditions: treatment plants handling floodwater-saturated intake face sharply elevated contaminant loads; private wells in low-lying FEMA-designated zones — which cover 79% of local ZIP codes — can be infiltrated by surface runoff carrying bacteria, sediment, and chemical residue; distribution systems under pressure during flooding can experience backflow that draws untreated water into the supply.
Arlington has a significant flood history with 1,042 FEMA flood insurance claims on record, averaging $14,928 per claim. With 79% 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>$2,042</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.
