Drinking Water Supply Well Monitoring goes Online

Drinking water supply well monitoring is a new regulatory requirement for Sacramento Valley growers/landowners starting January 1, 2022. Rice growers in the Sacramento Valley are automatically members of the Sacramento Valley Rice Growers Coalition, with the requirement specific to wells that supply drinking water on parcels where rice is produced. Drinking water supply wells on non-rice parcels receive coverage under the Sacramento River Watershed Coalition. Rice grown in the San Joaquin Valley starts earlier and growers/landowners are directed to the local water quality coalition.*

Thiobencarb Monitoring and Changes to REI

Monitoring for 2019

Thiobencarb monitoring starts at the Colusa Basin Drain 5 (CBD5) on Tuesday – the typical start date of water quality monitoring. The CBD5 site is off Highway 20 in Colusa County, and receives drainage from both Colusa and Glenn Counties. The Colusa County Agricultural Commissioner’s office announced receipt of the first thiobencarb notice of intent (NOI) with applications under way. Confirmation of intent to apply thiobencarb from the other rice counties will trigger the decision to add in the remaining monitoring sites. We estimate this will happen as early as May 7.
