Housing & Infrastructure in Crandon
With 53% 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. Crandon's median build year of 1986 places it squarely in that category.
Over half of homes in Crandon were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Crandon Homeowners
Middle of the range — Crandon homeowners face a remediation share that calls for real financial attention without reaching crisis territory.
Remediation costs are moderate relative to home values in Crandon. The estimated $950–$3,200 range is manageable for most homeowners but still worth budgeting for. Home values are 28% below the Wisconsin average.
Lead Exposure Risk for Children in Crandon
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 53% pre-rule share in Crandon keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Flood & Climate Risk in Crandon
Over the multi-decade window covered by the National Flood Insurance Program, Crandon has accumulated 1 claim — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Crandon has a moderate flood history with 1 FEMA claims averaging $8,211 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$1,900</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
