The EPA defines a water contaminant as any physical chemical, biological, or radiological substance or matter in water and prescribes legal limits on the levels of certain contaminants in drinking water. These legal limits reflect both the level that protects human health and the level that water systems can achieve using the best available technology for treatment.
EPA STANDARDS AND THE SAFE DRINKING WATER ACT
In addition, the EPA sets water-testing schedules and methods that operators of water systems, large and small, must follow, mandating acceptable techniques for treating contaminated water. The Safe Drinking Water Act gives individual states the opportunity to set and enforce their own drinking water standards if these standards are at least as stringent as the EPA's national standards.
STATE OVERSIGHT OF WATER SYSTEMS
California directly oversees water systems within the state and reviews the results of all water systems testing.
To ensure the safe quality of the public’s drinking water, California requires that water systems must sample from the source water and within the distribution system on a schedule established for your facility.
Heritage Systems manages these events by collecting samples at the appropriate time using correct techniques, by testing the samples using approved methods and by generating submittal reports to the state.
