Three-Year HTO/RWQCB Project Examines Septic System Pollution in Santa Ynez Valley
Los Olivos deadline for Fixing Problem is extended to April 2020
Onsite Wastewater Treatment Systems (typically referred to as septic systems or OWTS) located in the Santa Ynez River Valley, Santa Barbara County, have been linked to elevated nitrate levels in drinking water wells.
The highest risk to groundwater was found to be in Janin Acres, located adjacent to the Santa Ynez River with a relatively high density of OWTS and shallow groundwater. . .
