DISTRICT CULINARY USE

-- Data is derived from samples collected from 2017 through 2019 except fluoride and nitrate data, which also includes 2020 data.

1Fluoride levels in the District are adjusted to maintain levels between 0.6 and 0.8 ppm.
2The State of Utah requires monitoring for sodium even though no MCL has been established.
3The MCL for sulfate and total dissolved solids is established by the State of Utah.
– Data derived from 2020 samples.

1This value represents the running annual average for 2020.
– Data derived from 2020 samples. (Bacteria testing derived from 120 samples)

1 Highest monthly number of positive samples.
2This value represents the highest single measurement of combined filter readings taken every four hours during 2020.
3This value represents the lowest monthly percentage of combined filter readings meeting less than 0.3 NTU in at least 95% of the measurements taken each month during 2020.

-- Data is derived from samples collected from 2016 through 2019.
