Get the Data Out Real Time Data Dissemination from Isolated Monitoring Stations within the Delta American Water Works Association California-Nevada Section 2013 Fall Conference October 1, 2013 Mark Bettencourt California Department of Water Resources Municipal Water Quality Program Today’s discussion The Real Time Data and Forecasting – Comprehensive Program, a part of the California Department of Water Resource’s Municipal Water Quality Program. Program Design, Rules for Success and Goals Information Products In California, more than 20 million people rely on Sacramento - San Joaquin Delta water for all or part of their drinking water supply. Due to the organic nature of the Delta and its geographic relationship with seawater intrusion and agricultural runoff inputs, treatment of Delta water presents the challenge of providing protection from both pathogens and simultaneously from the formation of disinfection byproducts (DBP’s, chemicals potentially harmful to humans). Disinfectant (Chlorine) + Natural Organic Material (NOM) +/- Bromide → DBP’s (Trihalomethanes (THM’s), Haloacetic acids (HAA’s)) Chloroform Bromodichloromethane Chlorodibromomethane Bromoform Monobromoacetic acid Dichloroacetic acid Monochloroacetic acid Dibromoacetic acid Trichloroacetic acid Disinfectant (Ozone) + Bromide Bromate Bromate Would drinking water suppliers like to know what the quality of their source water is before it arrives at their treatment facilities? MWQP Mission Statement The mission of the Municipal Water Quality Investigations (MWQI) Program is to: a) Support the effective and efficient use of the State Water Project (SWP) as a source water supply used for municipal purposes through monitoring, forecasting, and reporting of SWP water quality. b) Provide early warning of changing conditions in source water quality used for municipal purposes. c) Provide data and knowledge based support for operational decision- making on the SWP. d) Conduct scientific studies of drinking water importance. e) Provide scientific support to the Department of Water Resources (DWR), the State Water Project Contractors Authority (SWPCA), MWQI Specific Project Committee (MWQI-SPC), and other governmental entities.

No changes are expected through the week. Current flow conditions on the Feather River at Gridley show cfs at about 5500. The NOAA River Forecast Center shows a possible stage increase through 10 August. In the San Joaquin River (near Vernalis), flow is currently just over 520 cfs. It is predicted to decrease to 430 cfs by 10 August. EC in the San Joaquin (at Vernalis) is averaging about 480 uS/cm. The predicted flow decrease could possibly produce an increased EC although the change would most likely be small. EC at Banks PP has been rising over the past month and as of 01 August; the average was 467 uS/cm. On the other hand, EC at Clifton Court Forebay stopped its upward trend on the 1st and has leveled off with the average coming in at about 490 uS/cm. Pumping has decreased from an average of 5818 cfs on 31 July to about 4000 cfs on 04 August. According to CDEC, daily average Delta total outflow was just above 6000 cfs on the 3rd and 4th. Model predictions show EC at selected points through 19 August leveling off. Could it be that EC's have peaked for the time being? EC above Jones pumping plant has also leveled off and is currently averaging just above 460 uS/cm. It leveled off on the same date as Clifton Court. Current average pumping just came up from 3272 cfs to 3515 cfs. The overall organic carbon trend at Banks is downward with TOC concentrations coming in near 2.5 mg/L and DOC at 2.35 mg/L. (The closeness of the TOC and DOC data indicates that the filters are over loading or there is a possible internal clog inside the carbon instrument.) Like Banks, Jones PP OC is also trending downward with levels at about 2.3 mg/L TOC and 2.1 mg/L DOC. At the Sacramento River station at Hood, TOC is running at 1.45 mg/L and DOC at 1.3 mg/L. (Current data suggests filter or instrument clogging.) Current OC levels at Vernalis are 1.8 mg/L for TOC and 1.2 mg/L for DOC. The latest information from the station lead indicates that the data is bad due to insufficient sample flow. Bromide at Banks is following EC and continues on an upward path. The current level is approximately 0.38 mg/L. At Vernalis, bromide is currently running at 0.22 mg/L and holding steady. Jones PP bromide appears to have leveled off following EC. The current level is 0.27 mg/L. Pumping data from Gianelli is currently not available. Bromide levels are currently coming in at about 0.1 mg/L while TOC and DOC are running at 3.6 and 3.3 respectively. Instruments: Banks: The instruments ran normally during the week. There was however an issue with the Sprint network on August 1st where we lost connectivity to the station.
