My last job involved managing the STORET water quality data systems for the San Francisco office of the U.S. Environmental Protection Agency. The San Francisco office is responsible for coordinating environmental programs in Arizona, California, Hawaii, Nevada and U.S. Territories in the Pacific Ocean. I am now a private contractor providing STORET related services. These links go to useful environmental information and organizations. The emphasis is on water quality information.
