Zero Tolerance Logo NOTICE: Under the City Council’s Zero Tolerance Policy, the City will not blend any detectable levels of perchlorate into its water system and your water is safe. To learn more about the City Council’s Zero Tolerance Policy, click here.

Rialto's Zero Tolerance Policy

Based on the fact that there is no agreement within the scientific community, let alone by lawmakers, on just how much perchlorate can safely be ingested, the Rialto City Council has adopted its “Zero Tolerance Policy.” Under the City’s policy, if a well tests positive for detectible levels of perchlorate, that well is shut down and taken out of service. Its water is not placed into the City’s water system unless and until it is outfitted with treatment equipment and the water tests “non-detect” for perchlorate using state-approved testing methods. In this manner, no detectable perchlorate is allowed into the Rialto Water System and the citizens served by Rialto may rest assured that their water is safe. Furthermore, it is the City’s position that this is the standard to which the City should hold the polluters accountable to clean the water.  Click here to read the City's Zero Tolerance Resolution.

The City continues to monitor all applicable State health goals, standards and health studies for perchlorate.  The Los Angeles Times article can be found here. The full National Institute of Environmental Health Sciences report can be found here.
