Housing & Infrastructure in Marinette
With 79% 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
Because the majority of Marinette's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1966 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Marinette 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 Marinette Homeowners
Property value and cost data for Marinette produce a moderate remediation-share classification — a level where advance financial planning has real practical value and the commitment is realistic for most homeowners who approach it deliberately.
Remediation costs are moderate relative to home values in Marinette. The estimated $800–$2,600 range is manageable for most homeowners but still worth budgeting for. Home values are 41% below the Wisconsin average.
Lead Exposure Risk for Children in Marinette
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.
Routinely in Marinette, where 79% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Flood & Climate Risk in Marinette
Over the multi-decade window covered by the National Flood Insurance Program, Marinette has accumulated 6 claims — 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.
Marinette has a moderate flood history with 6 FEMA claims averaging $1,152 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>$1,600</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.
