Document Description
The Los Osos Wastewater project consists of four main components: collection, treatment, effluent reuse and disposal, and solids treatment and disposal. The primary purpose of the project is to alleviate groundwater contamination, primarily nitrates, that has occurred at least partially because of the use of septic systems throughout the community. However, an important aspect of the wastewater project involves water resource issues because of seawater intrusion that is contaminating the Los Osos groundwater basin. Los Osos is located at the south end of Morro Bay, twelve miles west of the City of San Luis Obispo in San Luis Obispo County. The supplemental NOP describes potential treatment and effluent disposal sites.
