The City of Minnetrista provides drinking water to its residents from a groundwater source: four wells ranging from 253 to 787 feet deep, that draw water from the Franconia-Mt. Simon and Quaternary Buried Artesian aquifers.
The EPA has established two standards for additional contaminants in tap water:
MCL: Maximum Contaminant Level - The maximum allowable level of a certain contaminant
MCLG: Maximum Contaminant Level GOAL - The level where studies have found ZERO HEALTH RISKS, aka the "Health Limit"
Certain contaminants that absorb easily through your skin have been highlighted in orange. For those items, a Point of Entry (POE) system is recommended to treat all the water for your home/business.
