Avon Infrastructure Age
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
Housing age matters for water quality because lead solder was widely used in plumbing until the 1986 federal ban. Avon's median build year of 1990 suggests a majority of homes were constructed under the newer standard — a meaningful factor when assessing household-level lead risk from tap water.
Most homes in Avon were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Avon
Given current Avon valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Avon are relatively low compared to home values. The $1,900–$4,100 estimated range is a small fraction of median property value. Home values are 64% above the Indiana average.
Avon: 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.
If aggregate samples sit below the EPA action level and just 19% of Avon's inventory comes from the pre-rule era, systemic lead is not a dominant local concern. The aggregate still cannot tell a homeowner what is actually flowing from a specific faucet on a specific morning, which is why an in-home draw exists as a separate measurement at the household tier.

Avon: Flood History & Water Damage Risk
100% of ZIP codes in Avon are mapped into FEMA-designated flood zones, and the NFIP records 9 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Avon has a moderate flood history with 9 FEMA claims averaging $7,216 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>$2,900</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.

- 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.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
