How Old Is Mc Henry's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Banned from residential plumbing in 1986, lead solder was a near-universal feature of copper plumbing before that cutoff. In Mc Henry, where the median build year is 1990, the majority of housing falls into the post-ban category — though the older fraction of the stock still carries the residual risk that comes with pre-1986 pipe and solder materials.
Most homes in Mc Henry were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Mc Henry: Remediation Cost in Perspective
When remediation costs are measured against Mc Henry home values, the resulting ratio is in the low tier — addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.
Remediation costs in Mc Henry are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 46% above the Mississippi average.
Protecting Children from Lead in Mc Henry
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.
Despite citywide averages reading cleanly under the federal action threshold, the way utilities pull samples — from a representative subset rather than door-to-door — leaves room for individual buildings with older interior lines to behave differently than the aggregate suggests. With only 18% of Mc Henry stock predating the solder rule, that residual subset is small but real, and a draw-test kit gives the only direct read on what comes out of one faucet on a given morning.

Climate-Related Water Risk for Mc Henry
Taken together, Mc Henry's 1 NFIP flood insurance claim and 100% FEMA flood zone coverage place it in the moderate range of exposure. That middle position has specific implications for water quality. The contamination pathways that flooding can open — surface water overwhelming treatment facility intake, floodwaters infiltrating private wells, distribution pressure changes creating backflow — are not constant risks in a moderate-exposure community. But they do become active during significant flood events, and the claim record here indicates enough of those events to make flood timing an occasional factor in local water quality conversations.
Mc Henry has a moderate flood history with 1 FEMA claims averaging $11,745 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>$1,200</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.
