Corona’s residents can take comfort in knowing that the city’s drinking water continues to meet all state and federal standards, ensuring it remains safe and healthy to consume.

During the warmer summer months, there may be occasional changes in the raw water supply to Corona’s surface water treatment plants. This water is drawn from different zones of Lake Mathews, a key reservoir for the area. These changes can sometimes lead to stratification—a natural process where the water forms layers and doesn’t mix or aerate as it should. When this occurs, it can impact the taste and odor of the water, though these aesthetic changes do not affect its safety.

Seasonal source water changes like this are a normal part of the supply process and typically happen gradually. However, this year, the shift occurred more abruptly, making the changes in taste or smell more noticeable to residents.

Despite these occasional changes, rest assured that Corona’s drinking water remains fully compliant with all health and safety regulations. For those curious about their water quality, the city encourages residents to explore the latest Consumer Confidence Report, available at www.CoronaCA.gov/CCR.

Whether it’s the height of summer or any other time of year, you can trust that Corona’s tap water remains safe and clean.
