### Documention
Gorman Sanisaca, L., Skinner, K.D., and Maupin, M.A., 2019, Annual wastewater
nutrient data preparation and load estimation using the Point Source
Load Estimation Tool (PSLoadEsT): U.S. Geological Survey Open-File
Report 2019-1025, 48 p., https://doi.org/10.3133/ofr20191025.
### Abstract
The Point-Source Load Estimation Tool (PSLoadEsT) provides a user-friendly interface for
generating reproducible load calculations for point source dischargers while managing common
data challenges including duplicates, incompatible input tables, and incomplete or missing
nutrient concentration or effluent flow data. Maintaining a consistent method across an
entire study area is important when estimating loads to be used as calibration data for
regional water quality models. PSLoadEsT is written using the open-source programming
language R and has an easy-to-use interface written in Visual Basic for Applications? within
a Microsoft Access? database file that guides the user through the necessary steps to estimate
point source loads.
### Minimum System Requirements
1) Microsoft Windows? 7 or above
2) Microsoft Office? 2007-2016 with Microsoft Access? (32-bit)
3) Microsoft Access? Driver (*.mdb, *.accdb) (32-bit)
4) 64-bit Operating System
Refer to documentation Section 2 of documentation for detailed PSLoadEsT setup instructions.
