Housing & Infrastructure in Maywood
With 66% 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
Maywood's housing stock is predominantly older, with a median build year of 1973 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here — a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.
Over half of homes in Maywood 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 Maywood Homeowners
Is remediation financially manageable for Maywood homeowners? At a moderate equity share, generally yes — with deliberate budgeting ahead of time.
Remediation costs are moderate relative to home values in Maywood. The estimated $1,500–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 6% above the Missouri average.
Lead Exposure Risk for Children in Maywood
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.
66% of Maywood 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.

Flood & Climate Risk in Maywood
Flood activity in Maywood is neither negligible nor at the level of the highest-exposure areas in the NFIP dataset. The 2-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.
Maywood has a moderate flood history with 2 FEMA claims averaging $27,184 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>$2,700</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.
