EPA Announces
Arsenic Standard of 10 ppb. Must be met by January 2006 |

| Drinking
water may be contaminated by a variety of biological, chemical
or radiologic agents. To help safeguard consumer health, the
federal government has set standards for over 80 potential
drinking water contaminants. For a summary of current federal
standards, and associated health risks, see US
EPA Current Drinking Water Standards. For more detailed
background information on these contaminants see Drinking
Water Contaminants (US EPA). |

| Water
suppliers in Utah must conform to Utah
Rule R309-200. Drinking Water Standards. Utah's quality
standards are consistent with federal standards. However,
please note the following: |

|
•
Utah has a primary standard for TDS (Total Dissolved Solids).
The Maximum Contaminant Level (MCL) for TDS is 2000 milligrams/liter
(abbreviated as 2000 mg/l). Additionally, if TDS level is
greater than 1000 mg/l, a water supplier must satisfactorily
demonstrate that no better water is available. (The federal
government has a secondary, or aesthetic, standard for TDS
of 500 mg/l.) |

|
•
Utah has a primary standard for sulfate. The MCL for
sulfate is 1000 mg/l. If the sulfate level is above 500 mg/l
the water supplier must satisfactory demonstrate that no better
water is available and the water shall not be available for
human consumption from commercial establishments. (The federal
government has a secondary, or aesthetic, standard for sulfate
of 250 mg/l.) |

There are currently no federal or state standards for sodium
