Blue Diamond water quality
The Las Vegas Valley Water District produces a water quality report each year for Blue Diamond water customers, based on regular testing of the system. The Water District tests for more than 100 substances, but only those detected in Blue Diamond's drinking water are listed on the report's test results page.

Testing and treating the water supply
Blue Diamond's water supply is closely monitored. Every month, Las Vegas Valley Water District scientists collect and analyze water samples from Blue Diamond’s water supply to ensure it meets all Safe Drinking Water Act standards.
Because Blue Diamond's water supply is protected within the principal groundwater aquifer, it doesn't require the level of treatment associated with surface water sources.
Once pumped from the aquifer, Blue Diamond water is disinfected with sodium hypochlorite (chlorine) to kill any potentially harmful microscopic organisms.
The Blue Diamond Water System currently has monitoring waivers for certain chemical contaminants regulated by the Environmental Protection Agency (EPA).
A monitoring waiver means the Water District does not have to test the water for these chemicals at the frequency required by the EPA.
Waivers are granted by the Nevada Division of Environmental Protection after it has conducted a vulnerability assessment.
The assessment established that the water system is unlikely to be contaminated by these chemicals based on a study of:
- The geology of the area
- Past and current land uses (such as mining), and
- The existence of potential sources of contamination
