Arjay Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
When trying to understand water quality at the household level, the year a home was built often matters more than any city-wide water report. That's because the 1986 federal ban on lead solder in plumbing, and the earlier phase-out of lead pipes before 1970, created sharp discontinuities in residential plumbing risk by construction era. Arjay's median build year of 1996 puts the city in the transition zone: a substantial share of the housing stock postdates the solder ban, but a comparable fraction predates it — with the oldest homes carrying both the solder risk and the pipe risk simultaneously. Whether any individual household sits on the safer or riskier side of these thresholds is the key question, and it's one the city-wide median alone can't answer.
Most homes in Arjay were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Arjay: 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.
Locally, Arjay's indicators line up: aggregate readings pass under the regulatory benchmark and the pre-rule housing footprint at 30% keeps lead in a background position.

Arjay: Flood History & Water Damage Risk
21 FEMA flood insurance claims are on file for Arjay, and 100% of local ZIP codes fall within federally designated flood zones — enough to put flood exposure on the planning radar, though short of the concentrated-risk threshold where treatment-system vulnerability becomes a primary consideration.
Arjay has a moderate flood history with 21 FEMA claims averaging $7,495 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 Arjay
- 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.
