Utah Admin. Code R309-200-4 - General
(1) Maximum contaminant levels (MCLs) and
treatment techniques are herein established for those routinely measurable
substances which may be found in water supplies. "Primary" standards and
treatment techniques are established for the protection of human health.
"Secondary" regulations are established to provide guidance in evaluating the
aesthetic qualities of drinking water.
(2) The applicable "Primary" standards and
treatment techniques shall be met by all public drinking water systems. The
"Secondary" standards are recommended levels which should be met in order to
avoid consumer complaint.
(3) The
methods used to determine compliance with these maximum contaminant levels and
treatment techniques are given in R309-205 through R309-215. Utah Division of
Drinking Water adopts by reference the analytical methods incorporated in 40
CFR Parts 141, 142, and 143 as published on July 1, 2018.
(4) If the water fails to meet these minimum
standards, then certain public notification procedures shall be carried out, as
outlined in R309-220. Water suppliers shall also keep analytical records in
their possession, for a required length of time, as outlined in
R309-105-17.
