How Old Is Arlington's Housing Stock?
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
The story of Arlington's housing stock is one of layered development — neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 2007 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards — creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Arlington were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Arlington: Remediation Cost in Perspective
In Arlington, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Arlington are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 22% below the Arizona 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.
Reading Arlington's aggregate samples next to its housing-age figures yields a quiet baseline. Lead rests under the federal action benchmark in citywide monitoring, and only 30% of homes were built before the federal ban on solder containing lead. Households with kids — the population for whom CDC guidance places particular weight on minimizing exposure — can confirm in-home conditions with a draw-test kit, with a certified lead-removal filter available through certified retail channels if results warrant it.

Climate-Related Water Risk for Arlington
The National Flood Insurance Program captures decades of claims at the local level, building a record of cumulative community flood exposure. For Arlington, that record documents 1 claim and 100% of ZIP codes inside FEMA-designated flood zones. What makes those numbers relevant to water quality is the set of mechanisms flooding activates: heavy precipitation that floods treatment intake zones can introduce contaminants upstream of normal filtration; well casings in low-lying areas can be infiltrated by floodwaters carrying bacteria, sediment, and chemical residue; and distribution system pressure changes during flooding can create backflow conditions. These effects become more probable as flood frequency and magnitude increase — and the NFIP record indicates both are meaningful factors locally.
Arlington has a moderate flood history with 1 FEMA claims averaging $749 per payout. 100% of ZIP codes fall within FEMA flood zones. 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. Flood damage can add significantly to the estimated <strong>$1,600</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.

What You Can Do in Arlington
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
