The City of Loretto provides drinking water to its residents from a groundwater source: a 615 foott deep, which draw water from the Franconia-Ironton-Galesville aquifer.
Loretto’s high level of water hardness ranges from 24-26 grains which is almost 5x harder than the national average. The high level of chlorine, total dissolved solids (TDS), and organic matter also contribute to a poor overall taste.
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.
