Irrigated Land Regulatory Program - Trend Monitoring Group

Central Valley Groundwater Monitoring Collaborative (CVGMC)

CVGMC Conceptual Trend Monitoring Workplan
The trend monitoring program is designed to determine current water quality conditions of groundwater in the third-party areas, and to develop long-term groundwater quality information that can be used to evaluate the regional effects of irrigated agriculture and its practices.

The Central Valley Water Board's Executive Officer conditionally approved a conceptual Trend Monitoring Workplan submitted by the Central Valley Groundwater Monitoring Collaborative (CVGMC) on 31 October 2017. The expedited approval was issued in order to facilitate initial groundwater monitoring by fall of 2018. Stakeholders and other interested parties are invited to submit written comments on the conceptual workplan, which will be considered during review of the Phase 1 Technical Workplan described below. The deadline for written comments to be considered by the Executive Officer is 23 February 2018. Comments may be submitted to David Sholes at or hard copy to Attn: David Sholes, Central Valley Regional Water Quality Control Board, 1685 "E" Street, Fresno, CA 93706.

By 16 May 2018, the CVGMC intends to submit a Phase 1 Technical Workplan identifying the group's data collection and reporting methods, quality assurance measures, and potential coordination opportunities with other regional monitoring efforts currently under development. Once received the Technical Workplan will be circulated for a 30-day public comment period, during which stakeholders and other interested parties will be invited to submit written comments.
