What's in Aviston's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Aviston Infrastructure Age
With 46% 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.

Housing Age Profile
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Aviston's median build year of 1999 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on — and whether it predates 1970 — is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Aviston were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Aviston
Given current Aviston 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 Aviston are relatively low compared to home values. The $300–$2,300 estimated range is a small fraction of median property value. Home values are 28% above the Illinois average.
Aviston: 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.
Once federal rules removed lead solder from new plumbing, the older inventory still in service became the active risk surface. 46% of the Aviston housing stock comes from that earlier era, and citywide monitoring has crossed the action level.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
