Dixon/Solano RCD Water Quality Coalition
Water Quality Monitoring
Dixon/Solano RCD Water Quality Coalition conducts representative water quality monitoring on behalf of coalition members that includes regular sampling at the Ulatis Creek monitoring site and two groundwater sites (see map of monitoring sites below). Where water quality standards are exceeded, Management Plans are triggered. Water quality sampling is on a three-year cycle of assessment-core-core. This mean on an assessment year monthly monitoring occurs and on a core year (or non-assessment year), the monitoring is reduced to twice a year at sites with a previous exceedance from the prior year and that are in a management plan.
Approved annual monitoring plans and water quality summaries can be accessed at: https://www.waterboards.ca.gov/centralvalley/water_issues/irrigated_lands/water_quality/coalitions_submittals/#sacvalley
