The state of California actively encourages the use of properly treated wastewater for irrigation and other nonpotable purposes. This article describes current reuse practices in California and discusses contaminants of health significance in reclaimed water and their regulation by the state. The California Department of Health Services has established statewide reclamation criteria to assure health protection without unnecessarily discouraging wastewater reclamation. The regulations specify wastewater reuse standards for irrigation, impoundments, and groundwater recharge and include water quality standards, treatment process requirements, sampling and analysis requirements, operational requirements, and treatment reliability requirements. Controls on the delivery and use of reclaimed water by the state of California include guidelines that describe appropriate safety precautions and operational procedures such as cross-connection control provisions, confinement of discharge, color-coded reclaimed water lines and appurtenances, separation and construction criteria for domestic and reclaimed water pipelines, key-operated valves and outlets, fencing, signs, control of windblown spray and provisions for the protection of workers. Includes 43 references, tables.
