Recoding of AMDTreat Phase 2: Integration of PHREEQ-N-AMDTreat water-quality prediction tools with recoded AMDTreat cost-analysis software
Newly developed PHREEQ-N-AMDTreat water-quality prediction tools indicate potential changes in pH, dissolved metals, and associated solute concentrations resulting from passive and active treatment of coal-mine drainage.
AMDTreat's “user-friendly” caustic titration, parallel reactions, and sequential reactions tools utilize PHREEQC equilibrium (aqueous and surface speciation) and kinetics models with a user interface to facilitate input of initial data and analysis of results. Results include water-quality effects, quantities of reactants consumed, and amount of sludge produced by user-defined treatments. Different treatments can require vastly different land areas, equipment, and costs for construction, operation, and maintenance. With the hypothetical performance and sizing information indicated by PHREEQ-N-AMDTreat tools, the AMDTreat cost-analysis software, which is maintained by the U.S. Office of Surface Mining Reclamation and Enforcement (OSMRE), can be used to evaluate potential feasibility and cost-effectiveness of treatment alternatives.
The objective of the phase II project is to (1) develop detailed documentation for the PHREEQ-N-AMDTreat water-quality tools; (2) assist the OSMRE programmers with the integration of the water-quality tools into a new version of the AMDTreat cost-analysis software that is currently being recoded to run on Windows 10 and other platforms; and (3) modify the sequential reactions tool to add sorption and solubility reactions for trace metals and rare-earth elements.
Chuck Cravotta developed the PHREEQ-N-AMDTreat tools over several years. During the past year, he has been providing guidance to OSMRE staff, other professionals, and students who are working with testing of the stand-alone PHREEQ-N-AMDTreat versions that were issued to the public in 2020 by the USGS as a software release.
