Background

In April 2008, a workgroup of water resource agencies in the Santa Ana Watershed was convened by the Santa Ana Watershed Project Authority to work cooperatively with the Regional Board in investigating “emerging constituents” and determine which emerging constituents may be important to assure water quality protection in the Santa Ana River Watershed. The term “emerging constituents” used by the workgroup is synonymous with similar phrases used to describe the same phenomena such as emerging contaminants of concern, chemicals of emerging concern (CEC), micro-constituents, micropollutants, trace organics, etc. These other phrases may mistakenly imply that it is the concern that is emerging rather than the knowledge that certain chemicals may be present in a water sample. Similarly, referring to such compounds as emerging pollutants or emerging contaminants may mistakenly imply that the levels detected are a pollutant or contaminant of concern. Consequently, the term, “emerging constituents”, is used throughout this agreement to identify the focus of the Task Force efforts.

Stakeholder Effort

In 2007, a workgroup was formed among the water recharging agencies and POTWs to address a characterization program for emerging constituents. SAWPA was requested to administer the development of a two phased study approach.  The Emerging Constituents Workgroup study effort was separated in two phases. Phase 1 - covered current water quality monitoring programs, regulatory issues, stakeholder concerns, analytical methods, and the state-of-the-science with respect to potential public health & environmental impacts.  This phase culminated in a written report submitted to the Regional Board in Dec. 2008 characterizing the Workgroup's preliminary findings.       Phase 1 Report     Phase 2  - will reflect the results of ongoing Emerging Constituents characterization studies and other related evaluations to define an Emerging Constituents Investigative plan for the RWQCB approval by Dec. 2009.       Phase 2 Report
