Copper
Likely Pipe Material

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.

Housing Age Profile

The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing - from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Lyon, where the median build year is 1987, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.

Over half of homes in Lyon 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 Lyon Homeowners

Given current Lyon property values, the remediation share falls in the moderate tier - an indicator that the household financial perspective here calls for advance planning rather than dismissal, with most homeowners positioned to address documented issues through deliberate budgeting rather than needing to treat remediation as a significant equity event or financial emergency.

Median Home Value
$88,400
Est. Remediation
$1,500
Remediation as % of home value 1.7%

Remediation costs are moderate relative to home values in Lyon. The estimated $950–$2,400 range is manageable for most homeowners but still worth budgeting for. Home values are 31% below the Mississippi average.

Lead Exposure Risk for Children in Lyon

54%
Homes Built Before 1986
0.0027
mg/L Avg Lead (Limit: 0.015)

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.

Reading the local data together points toward a structural gap that matters more here than in low-exposure communities. 54% of Lyon stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.

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. The <strong>$1,500</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
