Abstract
In 2000, U.S. Bureau of Reclamation (Reclamation) and twelve cost sharing partners began the Southern California Water Recycling Projects Initiative (Initiative), which is a multiyear planning study. This study was established to assist local agencies in their recycled water planning for specific projects as well as addressing regional issues that may influence water recycling in southern California. One of the main objectives of the regional component is to assess and analyze potential future brine/concentrate management issues at a regional level. This issue is of particular concern to agencies in southern California that produce recycled water because of the potential salinity increases in water supplies and increasing discharge regulations.High salinity in reclaimed wastewater affects all users of reclaimed water including agriculture, horticulture, groundwater replenishment, and industry. Salinity in reclaimed water can interfere with reuse if it results in the water not being able to meet customer water quality needs and expectations or by not meeting regulatory requirements. The degree of restriction to reuse varies from none to severe, depending on the constituent concentration and the reuse application. The major salinity-related problems faced by reclamation agencies in southern California include:
This paper will discuss the analysis, results, and information accumulated to date as part of the Initiative project including the effect of potential increases of salinity on water reuse at a regional level such as:
