Housing Age Profile
Reading the housing age data for Milledgeville — median build year 1945 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Milledgeville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Milledgeville
The cost-to-equity ratio for remediation in Milledgeville is elevated — the financial planning challenge here is real and significant.
At 2.4% of home value, remediation costs in Milledgeville represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,600–$3,300. Home values here are 45% below the Illinois average.
Milledgeville: 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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 90% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Milledgeville.

Milledgeville: Flood History & Water Damage Risk
Over the multi-decade span captured by FEMA's National Flood Insurance Program, Milledgeville has accumulated a relatively small number of flood claims. That history points to a community where flood exposure is present but contained — and where the pathways by which flooding can affect water quality (overwhelmed treatment plants, contaminated private wells, distribution backflow) remain low-probability events rather than recurring concerns.
Milledgeville has a relatively low flood history with 1 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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>$2,400</strong> remediation cost per household.
