Provides a list of downloadable software for simulating groundwater flow, contaminant transport, water supply well capture zones, etc.
A set of prepackaged software tools developed and provided on-line by USEPA for performing simple site assessment calculations. Calculators allow easy calculation of groundwater hydraulic gradient, seepage velocity, and plume transport (1D and 3D).
Describes the process of seeping groundwater dissolving chemical contaminants from subsurface waste sources, and provides a list of common groundwater contaminants with associated sources of the contaminant and its potential health effects.
Compendium of information on water resources groundwater software in areas such as groundwater flow, contaminant transport, geochemical reactions, and groundwater-surface water interactions.
Discusses research into the use of computer models to better understand and forecast the behavior of contaminants in groundwater. Provides a list of free groundwater modeling software.
Presents an overview of the essential components of ground-water flow and contaminant transport modeling in saturated porous media. Groundwater contaminant transport processes, simple equations, input parameters, and applications are discussed, along with an explanation of the differences between analytical and numerical computer models.
Overview USEPA web page for information relating to water quality standards and requirements.
Compilation of state-promulgated and other water quality standards. Standards for a state can be accessed by clicking on that state in the interactive map. Documents summarizing Clean Water Act and other standards are provided.

PADEP website provides a free downloadable version of the Domenico plume transport solution as an Excel spreadsheet (QuickDomenico) with User Guide and example applications.
Provides Michigan Department of Environment guidance on the selection of software to analyze groundwater flow and/or contaminant transport at a contaminated site. Briefly describes criteria for analytical and numerical model selection.
Michigan guidance that discusses the use of groundwater models for environmental assessment and remediation at contaminated sites. Appendix E contains a good list of relevant modeling software with references.
Presents Ohio Environmental Protection Agency guidance on groundwater flow and contaminant transport modeling. Describes analytical models in general as compared with numerical models, and several good sections that discuss plume transport modeling.
NJDEP guidance that discusses agency guidance on any groundwater remediation program that includes Monitored Natural Attenuation (MNA) as a component. Describes transport modeling to evaluate possible plume impacts to receptors, and for forecasting plume behavior over time (velocity, area and volume time trends, mass flux, etc.)
Similar to New Jersey guidance but for State of Texas; discusses use of predictive modeling studies for understanding natural attenuation processes, time to reach cleanup standards, etc.
