The EPA Maximum Contaminant Level is: 10 ppm (parts per million) or mg/L (milligrams An easy way to think of ppm is to visualize putting four drops of ink in a 55-gallon barrel of water and mixing it thoroughly. This procedure would produce an ink concentration of 1 ppm. Some other analogies that may help you visualize the scale involved with ppm and ppb: One ppm is like- one inch in 16 miles, one second in 11.5 days, 2015-08-02 Water Report Conversion. Spreadsheet that can be used to convert to water values for profile can be found here. Brewfather uses ppm values for the water profile, so your water report have to be converted to this.

Depending on your water hardness number, daily water use and the number of people in the home, you may need a smaller—or larger—grain capacity softener. contaminants, including nitrate. To assist in water safety, the EPA has set standards for nitrate levels in public drinking water systems. Although private well owners are not required to meet these standards, they do serve as a reference for safe drinking water.
