`All anaytes W N be analyzed at the same laboratory except E.Coli and Total Coliform. These parameters will be analyzed at a
separate laboratory that specializes in bacteria analysis.
The above standards originated from the Colorado Department of Public Health and Environment Regulation NO.41:
https://www.colorado.gov/pacific/sites/defaulUfiles/41_2016%2806%29hdr.pctf. The more stringent standard will be used if more than one standard ebsts
for a parameter.
