Workshop Memorandum 19-101

Date: April 9, 2019

From: Jennifer Ares, Water Resource Manager

Subject: Overview of the 2019 Groundwater and Surface Water Monitoring for the Yucaipa
Valley Water District’s Maximum Benefit Monitoring Program

Yucaipa Valley Water District is required to conduct extensive monitoring for the Maximum Benefit
Program in the San Timoteo and Yucaipa Management Zones pursuant to the Regional Water
Quality Control Board (RWQCB) Resolution Nos. R8-2005-0065 and R8-2014-0005.

The following scope of work and fee are based on monitoring requirements included in Resolution
No. R8-2014-0005 from the Regional Water Quality Control Board. The monitoring will include
groundwater monitoring services at up to fourteen wells in the San Timoteo Management Zone
and three wells in the Beaumont Groundwater Management Zone. This will include collecting
groundwater quality samples from seven of the wells. Surface water monitoring services at up to
four surface water monitoring points in the San Timoteo Management Zone will also be conducted
bi-weekly.

All data collected in the field (e.g. groundwater level measurements, surface water flows) will be
compiled in a database, along with analytical laboratory results for all water quality samples
collected by Dudek. Dudek will manage the data for the San Timoteo Creek, Yucaipa, and
Beaumont Management Zones. This includes collecting, reviewing, providing quality control and
quality assurance, and compiling all groundwater and surface water data from the three
management zones.

The District was under contract with Dudek for the 2018 groundwater and surface water
monitoring for the San Timoteo Management Zone and the 2018 Maximum Benefit Report will
be submitted to the Regional Water Quality Control Board by April 15, 2019. This current proposal
covers the monitoring requirements for the 2019 calendar year.
