TracerLPM (Version 1): An Excel® Workbook for Interpreting Groundwater Age Distributions from Environmental Tracer Data

TracerLPM is an interactive Excel® (2007 or later) workbook program used to evaluate groundwater age distributions from environmental tracer data by using lumped parameter models (LPMs). User-defined age distributions, such as those determined from particle tracking, and those generated from LPMs can be used to calculate past and future concentrations of non-point source contaminants and in evaluating the response of wells or receptors to changes in source loading using TracerLPM.
