See the record ↓Amsterdam's drinking water received a grade of B- (70.7 out of 100), indicating fair water quality. The city's 1 water system serves approximately 752 residents using surface water.
Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 59 violations on record, including 39 health-based violations. 5 remain unresolved.
Amsterdam ranks #384 out of 487 cities in Missouri for water quality, placing it among the lowest-rated in the state. The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection. As a small community water system, Amsterdam may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 12 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

03Amsterdam's ten-year track record
Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 59 violations on record, including 39 health-based violations. 5 remain unresolved.
6 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.

As a surface-water system, these water bodies may directly influence Amsterdam's drinking water supply.
05Pressure on Amsterdam's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Industrial discharge
1 facility within 10 miles reported 32 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Flood & storm history
4 federal disaster declarations on record for Bates County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
