Key Contaminants Detected in Hanover

How Old Is Hanover's Housing Stock?
With 70% 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 Hanover's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1969 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Hanover were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Hanover: Remediation Cost in Perspective
In Hanover, the remediation-to-property-value ratio is elevated enough that homeowners who identify documented issues early have an advantage — understanding the scope, sequencing by urgency, and phasing the work against household budget capacity are the practical levers that determine whether remediation feels manageable or overwhelming at this equity tier.
At 2.6% of home value, remediation costs in Hanover represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,000–$4,000. Home values here are 25% below the Kansas average.
Protecting Children from Lead in Hanover
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 Hanover represents 70% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Climate-Related Water Risk for Hanover
Within the NFIP's national dataset, Hanover falls in moderate-exposure territory — 1 documented incident spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Hanover has a moderate flood history with 1 FEMA claims. 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>$3,000</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.
