Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Ione Infrastructure Age
With 64% 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
Pre-1986 plumbing is not a rare legacy case in Ione — it's the dominant profile. The median build year of 1974 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Ione were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Ione
Looking at how documented remediation costs fit within Ione 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 Ione. The estimated $2,600–$5,500 range is manageable for most homeowners but still worth budgeting for. Home values are 48% below the Washington average.
Ione: 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.
64% — that captures the slice of Ione housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.

Ione: Flood History & Water Damage Risk

Ione has a moderate flood history with 1 FEMA claims averaging $54,820 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.

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.
