Class "A" waters are suitable for which use?

Class "A" waters are designated as the highest quality reclaimed water and are suitable for direct use in drinking water applications, assuming proper treatment is provided. This classification indicates that the water meets stringent health and safety standards, making it acceptable for human consumption and aligning with regulatory requirements for potable water.

Drinking water must be rigorously treated and tested to ensure it is free from contaminants and pathogens that could pose health risks. Class "A" waters undergo advanced purification processes, ensuring they are safe for direct human consumption. In contrast, the other uses listed, while important, do not require the same level of treatment and safety that drinking water does. Agricultural irrigation, industrial processes, and swimming can all use water that may not meet the same stringent qualifications, allowing for broader classifications that may include lower water quality standards.
