Water Samples

Herriman City takes numerous water quality and chemical level samples throughout the system on a daily basis (all 365 days of the year) to guarantee water quality and safety. Due to absence or low levels present, many of the following source samples have been changed to a reduced monitoring schedule every three or six years. The Water Department also performs a full-spectrum test on all wells every other year to monitor for many contaminants not required for monitoring.

Distribution system samples	Number of samples	Additional information
Fluoride	4-5 biweekly = 9 per month	One sample is sent to the state lab per month to ensure accuracy of our test equipment
Disinfection byproduct	4 per quarter = 16 per year	Monitoring the effects of chlorine in the water.
Lead and copper	20 every 3 years	Lead and copper samples must be taken in homes that have copper water lines with seed solder installed (between 1983 and 1988). This is done to determine if the water pH is leaching contaminants out of the pipes in the home.
Chlorine residuals	30 per month = 360 per year	Presence of chlorine is an indicator that there will not be bacteria in the water.
Bacteriological	30 per month = 360 per year	Taken to ensure no bacteria is present in the water.
