WHAT THE MEASURE IS SHOWING

The data show that of the State's 2,589 active cases, 687 cases (27 percent) were in active remediation during Fiscal Year (FY) 2015-16. Active remediation actions to clean up and remediate the effects of pollution vary by case. Of the remaining active cases statewide, 44 percent of all cases (1,149 cases) were in in site assessment in FY 2015-16; 18 percent of all cases (466 cases) were in assessment and interim remediation in FY 2015-16; and 260 cases (10 percent) were in verification monitoring in FY 2015-16. Compared to the other Regional Water Boards, the Central Valley Region (Region 5) has the largest number of active cases not in active remediation. Statewide, the number of cases in active remediation has remained consistent over time, with 686 cases in FY 2008-09, 688 cases in FY 2009-10, 716 cases in FY 2010-11, 716 cases in FY 2011-12, 688 cases in FY 2012-13, 729 cases in FY 2013-14, 710 cases in FY 2014-15, and now 687 cases in FY 2015-2016.

WHY THIS MEASURE IS IMPORTANT

The process of cleaning and remediating the impacts of pollution may take several years and may be completed in different phases. For as long as a case is active, work is done to investigate the nature and extent of the contamination, determine appropriate cleanup goals, and construct/implement actions to effect cleanup (remediation). In some cases the investigation may lead to a determination that no further action is needed. A case remains active until this determination is documented. Tracking the number of cases in active remediation and active cases is important to assess the current workload, plan future workload and funding requirements, and evaluate the program's results. The start of active remediation is a major milestone for a cleanup case, signifying the start of "on the ground" remediation. This performance measure is intended to show how well the Water Boards are doing at getting cleanup cases to this important milestone.

TECHNICAL CONSIDERATIONS

  • Data source: GEOTRACKER. Period July 1, 2015 to June 30, 2016.
  • Unit of Measure: Number of cases.

GLOSSARY:

Site Cleanup
The Site Cleanup program addresses commercial, industrial and other non-military sites with non-fuel contamination. Many of these sites are considered Brownfields because of their reuse potential. These sites are regulated under Site Cleanup Requirements, which are issued by the Regional Water Boards. Site Cleanup Requirements generally mandate a time schedule for specific tasks that must be performed by the responsible party(ies) to investigate and clean up the site. Water Board staff oversee implementation of these tasks including investigations, corrective actions, and human health risk assessments at sites with current or historic unauthorized discharges, which have adversely affected or threaten to adversely affect waters of the state.

Procedures for site investigation and remediation are promulgated in State Water Resources Control Board Resolution No. 92-49 entitled Policies and Procedures For Investigation and Cleanup and Abatement of Discharges Under Water Code Section 13304. Responsible parties conduct work in a stepwise fashion, starting with preliminary assessment, then soil and water investigation; interim remedial measures if warranted; risk assessment; setting cleanup goals; cleanup plan; cleanup implementation and monitoring. Most often, responsible parties conduct the work voluntarily, but sometimes enforcement orders are necessary to compel the work to be performed.

Active Remediation
Active remediation comprises the phase(s) of work where the actual construction or implementation of activities to accomplish cleanup at a site occurs.

Case Closure
A site cleanup qualifies to receive a "No Further Action" (closure) letter once the owner or operator meets all appropriate corrective action requirements. After this occurs, the county agency or regional board will inform the responsible party in writing that no further work is required.

Number of cleanup cases groundwater contaminant migration under control
Means a count of all open Water Board-lead cases and Shared-lead cases where groundwater contaminant migration has been evaluated as of the end of the Fiscal Year.
