Science and Products
Modules based on the geochemical model PHREEQC for use in scripting and programming languages
PHAST version 2-A program for simulating groundwater flow, solute transport, and multicomponent geochemical reactions
Geochemical investigation of the Arbuckle-Simpson Aquifer, South-Central Oklahoma, 2004-06
Brine migration from a flooded salt mine in the Genesee Valley, Livingston County, New York: Geochemical modeling and simulation of variable-density flow
Geochemistry of the Arbuckle-Simpson Aquifer
NetpathXL - An excel interface to the program NETPATH
Geochemical effects of induced stream-water and artificial recharge on the Equus Beds Aquifer, South-Central Kansas, 1995-2004
Age-dating ground water beneath Tinker Air Force Base, Midwest City, Oklahoma, 2003-04
Hydrologic and geochemical evaluation of aquifer storage recovery in the Santee Limestone/Black Mingo Aquifer, Charleston, South Carolina, 1998-2002
PHAST--a program for simulating ground-water flow, solute transport, and multicomponent geochemical reactions
Reactive-transport simulation of phosphorus in the sewage plume at the Massachusetts Military Reservation, Cape Cod, Massachusetts
Calculation of individual isotope equilibrium constants for implementation in geochemical models
PHREEQC Version 3
PHREEQC Version 3 is a computer program for speciation, batch-reaction, one-dimensional transport, and inverse geochemical calculations.
PHAST - A Computer Program for Simulating Groundwater Flow, Solute Transport, and Multicomponent Geochemical Reactions
PHAST Is a computer program for simulating groundwater flow, solute transport, and multicomponent geochemical reactions.
Water, Energy, and Biogeochemical Model (WEBMOD)
The Water, Energy, and Biogeochemical Model (WEBMOD) uses the framework of the U.S. Geological Survey (USGS) Modular Modeling System (MMS) to simulate fluxes of water and solutes through watersheds. WEBMOD divides watersheds into model response units (MRU) where fluxes and reactions are simulated for several hillslope reservoir types.
