Abstract

Abstract: A soil column study was conducted at an advanced water purification and groundwater recharge facility to evaluate potential causes of observed percolation rate decline during recharge for potable reuse. To measure the influence of pipeline transit and the environment on water quality and clogging potential of the purified water, columns were fed with (1) finished product water, (2) the same water after pipeline conveyance collected from the end of the pipe just before groundwater recharge, and (3) water from the basin (surface water pond) after environmental exposure to factors such as sunlight, algae, wildlife, wind‐blown dust, and sidewall erosion. Column performance results showed that percolation decline occurred at different rates across the three source waters, indicating that clogging potential increases significantly from the water's transit through the pipeline and further increases after exposure to the basin environment. The results offer insights for optimizing managed aquifer recharge operations utilizing advanced treated recycled water.
