La Belle ranks #318 out of 487 cities in Missouri for water quality, placing it below average 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. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, La Belle may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in La Belle's water
Every contaminant flagged in La Belle, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.
Near Limit — EPA Action Level: 15 ppb
Within EPA limits but above the American Academy of Pediatrics recommended level of 1 ppb — no lead level is considered safe for children. An NSF 53-certified filter provides additional protection, and running the cold tap 30 seconds after stagnation reduces exposure.Full contaminants report
