How Old Is Mills's Housing Stock?
With 62% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Mills's median build year of 1977 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Mills were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mills: Remediation Cost in Perspective
Because estimated remediation claims a substantial fraction of typical Mills property equity, the household financial perspective here requires serious advance planning — the cost-to-value ratio is in the elevated tier and warrants structured preparation.
At 2.1% of home value, remediation costs in Mills represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,300–$5,500. Home values here are 50% below the Wyoming average.
Protecting Children from Lead in Mills
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 62% pre-rule share in Mills keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Climate-Related Water Risk for Mills
Mills's NFIP claim count stays on the lower side of the range, suggesting flood exposure that merits baseline awareness rather than active mitigation planning. Water-quality implications of flooding are minimal when events are infrequent and limited in scale.
Mills 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>$3,600</strong> remediation cost per household.
