2023 Water Quality Monitoring Start

2023 Water Quality Monitoring Start

Surface Water Monitoring Programs Begin Next Week on May 9th 

The Rice Pesticide Program (RPP) will begin next week on May 9th.  The RPP monitors for thiobencarb for 10 consecutive weeks at 4 agricultural drain sites (2 east and 2 west of the Sacramento River), and one site in the Sacramento River near downtown Sacramento and upstream of the drinking water intake facilities. 

The monitoring program for the Waste Discharge Requirements (WDR) and the Pyrethroid Pesticides Total Maximum Daily Load (TMDL) will commence the following week at the same 4 agricultural drain sites.  The WDR program monitors 2 selected pesticides and general water chemistry.  The TMDL program monitors pyrethroids, water and sediment toxicity, and other general water chemistries.  Each of the 3 programs will conclude mid-July.  Groundwater monitoring at 10 select shallow wells across the rice-growing areas of the valley will be conducted in August.

The results of the water quality monitoring programs are used by the Central Valley Water Board and other stakeholders to determine compliance with our regulatory orders and to evaluate our industry management practices.
