How Old Is Coahoma's Housing Stock?
With 54% 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
Reading the housing age data for Coahoma — median build year 1985 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Coahoma were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Coahoma: Remediation Cost in Perspective
The equity share of documented remediation in Coahoma is high — a cost-to-value ratio that places this market in the elevated tier and means most homeowners are weighing a financial decision where scoping by urgency, mapping costs against household budget, and knowing what assistance options exist are practical steps that can materially improve outcomes.
At 2.3% of home value, remediation costs in Coahoma represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $950–$2,400. Home values here are 49% below the Mississippi average.
Protecting Children from Lead in Coahoma
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.
54% of Coahoma housing dates to the pre-rule era, alongside aggregate readings hovering at the federal action mark — household-level confirmation through a draw-test kit fits the local picture.

Climate-Related Water Risk for Coahoma
Flood activity in Coahoma is neither negligible nor at the level of the highest-exposure areas in the NFIP dataset. The 22-claim record and 100% flood zone coverage suggest a community that has experienced recurrent events but has not faced the kind of sustained, severe exposure where water-supply contamination becomes a primary public health concern. It sits in a middle range where flood history merits inclusion in any complete local water quality picture.
Coahoma has a moderate flood history with 22 FEMA claims averaging $4,055 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>$1,500</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.
