Key Points about Rancho Cucamonga's Water Quality:

1. Source: Rancho Cucamonga's water mainly comes from a combination of groundwater and imported water from the State Water Project and the Colorado River Aqueduct. This diverse sourcing helps in maintaining a stable water supply.
2. Testing and Standards: The water department conducts regular testing to ensure compliance with the standards set by the Environmental Protection Agency (EPA) and the California State Water Resources Control Board. These tests are aimed at detecting any contaminants like lead, bacteria, and other pollutants.
3. Water Hardness: The water in Rancho Cucamonga is known to be moderately hard, with a significant amount of calcium and magnesium minerals. This is a common characteristic in areas with mixed water sources, particularly those involving groundwater.
4. Common Concerns: Some residents report concerns such as a slightly chlorinated taste or mineral deposits on fixtures and appliances. While these issues are generally not harmful, they can be inconvenient. Residents sensitive to these characteristics might benefit from additional water treatment solutions.
