To improve early detection, monitor multiple sides of a pond using one array and eliminate many physical site limitations, correction geometric factors (GF) were developed. These GF were generated using georeferenced probe locations and applied to non-collinear arrays to correct for angular discontinuities. Next, a near-surface data analysis protocol was developed that had user-set thresholds to allow scaling of instrument sensitivity. The protocol used a statistically-based process for calibrating the reference data for a wide range of geological and geographical settings. This protocol allowed the RA technology to be automated to continuously monitor for leakage and when thresholds are exceeded, send an alert message to managers of potential problems. These advantages provide substantial improvements for protecting soil and groundwater quality from wastewater pond leakage.(Download PDF) (Export to EndNotes)
