Document Description
The Department of Health Services (DHS) has determined that groundwater produced at the Trabuco Canyon Water District's (District) Rose Canyon Wellfield is under the direct influence of surface water, and is therefore subject to USEPA's Surface Water Treatment Rule. As a result, the District must provide filtration to protect against microbiological contaminants. Various treatment alternatives were evaluated by the District to meet the filtration requirements, including the proposed use of riverbank with dual media pressure filters followed by ultaviolet (UV) and chlorine disinfection. The District has produced groundwater at the Rose Canyon Wellfield since 1962 and is seeking to continue use of these wells at the historical pumping average of 350 acre-feet per year (AF/YR), but with the additional level of treatment required by DHS. Additional improvements would consist of the expansion of the existing well house 18 feet in length to provide a separate 12' by 18' building. A 10' masonry wall would be constructed along the perimeter of the well site to enclose the proposed equipment and the existing well house. New equipment would include two partially buried 30,000 gallon tanks and pumps. All improvements would be contained within the District's existing 3-acre graded parcel.
