Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Amazonia'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
Over the decades, Amazonia accumulated housing from multiple construction periods. The median build year of 1998 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited — leaving a sizable share of homes on each side of that safety line.
Most homes in Amazonia were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Amazonia: Remediation Cost in Perspective
The equity share of documented remediation in Amazonia 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 3.3% of home value, remediation costs in Amazonia 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 49% below the Missouri average.
Protecting Children from Lead in Amazonia
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 40% of the Amazonia inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Climate-Related Water Risk for Amazonia
Multiple flood events have been recorded for Amazonia through the NFIP — 116 claims in total, with 100% of ZIP codes in FEMA-designated zones — pointing to a flood exposure profile that merits inclusion in a water quality assessment without reaching high-severity planning territory.
Amazonia has a moderate flood history with 116 FEMA claims averaging $31,512 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>$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.
