Kyle Canyon water quality

Message about Kyle Canyon water quality

During its most recent water testing conducted in Kyle Canyon, the Kyle Canyon Water District identified three homes where lead concentrations exceeded the Environmental Protection Agency’s "action level" of 15 parts per billion (ppb). Because lead in drinking water often emanates not from the public water supply but rather from lead-based plumbing components within individual properties, water agencies analyze water samples collected from homes within their service area.

Ten samples were taken from the Rainbow subdivision in the Kyle Canyon Water District service area. Three were above the threshold.

No lead was found in water from the Rainbow Well, which provides water to the subdivision. Because no lead was detected in the Rainbow Well and the Kyle Canyon Water District has no lead service lines, it is almost certain that the lead found in these three homes was the result of lead from the homes' plumbing fixtures and/or solder dissolving into the water at it sits in the pipes, a process called "leaching."

The Southern Nevada Water Authority (SNWA) and Kyle Canyon Water District have implemented effective countermeasures to inhibit the corrosion of plumbing and reduce the potential for leaching of lead and copper. In order for the countermeasures to remain effective, water use inside the home must be frequent, avoiding long periods of stagnation. For full-time residents, daily water use is frequent enough for the countermeasures to be effective.

For part time residents that do not use water daily, it is recommended that flushing before use occurs. Two of the homes with samples that exceeded the action level are unoccupied for large portions of the year.

Lead is a potential health threat that should not be ignored. It is particularly serious for children and pregnant women. Because homes are built using a variety of plumbing materials—particularly homes built before 1990—the only way to determine whether lead is present is by testing the household water.

Kyle Canyon residents who have questions or would like the water in their homes tested for lead should call the Kyle Canyon Information line at 702-822-8322. These tests are free of charge.

The Las Vegas Valley Water District produces an annual water quality report for Kyle Canyon water customers. The Water District tests for more than 100 substances, but only those detected in Kyle Canyon's drinking water are listed on the report's Test Results page.

Water analysis and source water assessment

Water treatment

Because Kyle Canyon'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, the water is disinfected with chlorine to kill any potentially harmful microscopic organisms.

Every month, Las Vegas Valley Water District scientists collect and analyze water samples from Kyle Canyon's water supply to ensure it meets all Safe Drinking Water Act standards.

Monitoring waivers

The Kyle Canyon Water District 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 contaminants at the frequency required by the EPA. In order to receive a waiver, the Nevada Division of Environmental Protection conducted a vulnerability assessment.

The assessment established that the water system is unlikely to be contaminated by these chemicals based on a study of:

  1. The geology of the area
  2. Past and current land uses (such as mining), and
  3. The existence of potential sources of contamination

For details about the specific chemicals for which there are monitoring waivers, please contact us.
