MODFLOW-2005 and MODPATH-6 Data sets of Simulated Groundwater Flow to Evaluate Wellbore Flow in Generic Long-Screened Wells Under Ambient Flow A generic, three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00) and MODPATH-6 (version 6.0.01), was created to better understand the amount of vertical flow and cross-contamination of trichloroethene (TCE) that may be occurring in discontinued extraction wells under current (2018-19) ambient-flow conditions at site 25 of the Edwards Air Force Base, California. The wells are long-screened (100-ft long), contain a surrounding sandpack, and have not been pumped for approximately 10 years. The groundwater flow model utilized multiple observations made from the field measurements of flow and transport to conceptualize, calculate, and simulate in-well flow, and flow in the sand pack. The model was... Tags: California, Cross contamination, Edwards Air Force Base, Geophysics, Groundwater Model, All tags...
