A preliminary survey was conducted to determine the efficacy of selected advanced onsite septic systems for the removal of selected pharmaceuticals and personal care products (PPCPs). The following technologies were chosen for this survey: standard “Title 5″ system comprised of a stone trench overlying sixty inches of sand, a recirculating filter unit containing fibrous peat, a single pass filter with open-cell foam, an upflow sulfur-filled filter following an aerobic treatment unit and a recirculating sand filter designed in accordance with standard practice. A system consisting of a filter of twenty-four inches of sand was used as a surrogate measure of influent wastewater sue to analytical issues with examining the matrix of raw wastewater.
