Stillwater Infrastructure Age
With 96% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Stillwater's median build year of 1902 places it squarely in that category.
Over half of homes in Stillwater were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Stillwater: 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.
Older stock in Stillwater represents 96% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Stillwater: Flood History & Water Damage Risk
Flood risk in Stillwater sits in a low-exposure range — NFIP claim volume is contained and FEMA flood zones cover a small portion of the area. For residents monitoring water quality, low flood frequency generally correlates with lower probability of the contamination events that flooding can introduce: overwhelmed treatment intake, well infiltration, and distribution backflow all require significant event size to materialize.
Stillwater 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>$3,000</strong> remediation cost per household.
