What's in Garden City's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Garden City 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
Post-1986 construction is where the lower lead-solder risk lives, because that's when the federal ban on lead solder in plumbing took effect. In Garden City, where the median build year is 1993, the housing stock falls broadly on the newer side of that threshold — a distribution that moderates aggregate plumbing-era risk compared to older housing markets.
Most homes in Garden City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Garden City
Because property values in Garden City comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Garden City are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 41% above the Idaho average.
Garden City: 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.
Since the federal solder ban took effect, new plumbing has been built without that pathway, and Garden City's pre-rule stock at 28% reflects a contained footprint.

Garden City: Flood History & Water Damage Risk
21 FEMA flood insurance claims are on file for Garden City, and 100% of local ZIP codes fall within federally designated flood zones — enough to put flood exposure on the planning radar, though short of the concentrated-risk threshold where treatment-system vulnerability becomes a primary consideration.
Garden City has a moderate flood history with 21 FEMA claims averaging $2,174 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>$2,200</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.

What You Can Do in Garden City
- Test your water at home. City-level data shows averages — your tap may differ. Lead testing is especially recommended given the area's lead levels.
- Install a certified water filter. Filters rated for Contaminant 0700 can reduce the most common contaminant found in Garden City's water.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
