How Old Is Forrest's Housing Stock?
With 85% 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
Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1952 places Forrest's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era — and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.
Over half of homes in Forrest were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Forrest: Remediation Cost in Perspective
In Forrest, the equity share of documented remediation is meaningful enough to move the household financial perspective from routine maintenance into deliberate budgeting territory — the cost-to-value ratio is moderate, and most homeowners benefit from mapping the full scope against available budgets before committing.
Remediation costs are moderate relative to home values in Forrest. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 16% below the Illinois average.
Protecting Children from Lead in Forrest
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, 85% of Forrest homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.

Climate-Related Water Risk for Forrest
A low NFIP claim count in Forrest suggests that flood events — when they occur — have been limited in extent. That pattern matters for water quality in a specific way: the mechanisms through which flooding degrades drinking water (treatment plants taking in heavily contaminated floodwater, septic and well systems backing up, distribution pipes experiencing pressure inversions) are all stress-threshold events. They become relevant when floods are frequent enough or severe enough to overwhelm normal infrastructure. At the volume this area shows, that threshold has rarely been approached.
Forrest 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.
