CASA Comments on San Diego Regional Board Exfiltration Investigative Order

CASA recently submitted comments to the San Diego Regional Water Board in response to a draft Investigative Order that would require the submittal of technical and monitoring reports to quantify sources and pathways of human fecal material to the San Diego River watershed. The Investigative Order would require area agencies to expend significant resources investigating sources of HFM without any demonstration of a nexus between an impairment and sanitary sewer exfiltration.

The order would also require agencies to address issues and potential sources outside their jurisdiction and control and take actions ahead of developing studies on the role of exfiltration in the watershed. The Regional Water Board established a webpage focused on this order. CASA will continue to track this issue as it develops.
