Future and Past Programs - Current Luncheon “Recycling Water” Speaker Californians tend to take water for granted because it’s relatively inexpensive, abundant, and easily available by just turning on the tap. However, California is now encountering increasing water supply problems and limitations. As many of you know, two-thirds of available fresh water exists in the water-rich north, but two-thirds of a thirsty population inhabits the south. Moreover, our population of approximately 37.3 million people (2010 census) may increase to between 41.5 to 52 million by 2025 and perhaps to even 63.4 million by 2040. With periodic droughts, potential climate change, reduced Sierra Nevada snowfall, lack of additional water storage behind no new dams, and increasing overdraft of groundwater supplies, we are now facing a potential water crisis additionally exacerbated by stretched water resources, no longer capable of meeting either current or future needs. Consequently, the search for additional supply now includes recycled water (RW). This is water primarily produced from domestic wastewater treatment or water reclamation plants that can purify wastewater to meet or exceed state and federal drinking water standards and render it safe for specified municipal uses. This talk will review the history of California’s RW use, California’s RW regulations and requirements, indicator and other chemical compounds required for RW in Groundwater Recharge Reuse Projects (GRRPs), and potential associated RW risks.
