The project was designed to examine the feasibility of an effluent-irrigated chaparral ecosystem as a greenbelt fuel-break for fire prevention, and to serve as a renovation system for wastewater recycling. An expanded water monitoring program encompassing analyses of surface and ground waters was implemented as an indicator of areas of wastewater contaminant accumulation. Soils and plants were analyzed for nutrient removal characteristics and patterns of native and introduced vegetation survival and growth were correlated into a feasible design for an effective greenbelt vegetation system. Results appear to be favorable to the project objectives of wastewater renovation and fire suppression through greenbelt establishment.
