What's in Marion's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Marion Infrastructure Age
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
Lead solder was federally prohibited in new plumbing in 1986. In Marion, the median build year of 1993 puts a majority of homes in the lower-risk category for that specific contamination pathway — though the pre-1986 share shown above still carries real exposure potential at the individual household level.
Most homes in Marion were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Marion
Looking at how documented remediation costs fit within Marion property values, the equity share lands in the moderate tier — a finding that positions the household financial perspective between routine maintenance and a significant budget commitment, where most homeowners can successfully address documented issues by treating the expense as a planned financial priority rather than an unexpected one.
Remediation costs are moderate relative to home values in Marion. The estimated $1,350–$3,100 range is manageable for most homeowners but still worth budgeting for. Home values are 54% above the Arkansas average.
Marion: Lead Risk & Vulnerable Populations
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.
In Marion, the older-stock footprint runs at 29% — a contained slice — and aggregate utility readings land safely under the EPA action mark. That keeps lead off the local priority list, with a one-faucet draw remaining the only direct read on a specific address.

Marion: Flood History & Water Damage Risk
Over the multi-decade window covered by the National Flood Insurance Program, Marion has accumulated 32 claims — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Marion has a moderate flood history with 32 FEMA claims averaging $22,931 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>$2,100</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.
