Mining throughout the Floridan aquifer system alters groundwater conditions. Determination of magnitude and extent of groundwater alterations in this regional karst aquifer system is difficult due to preferential flow paths, blasting, and widespread aquifer withdrawals and injections. Additionally, hydrologic models do not reveal subsurface impacts to the biotic environment, such as destruction...

[1] Understanding how changes in land use affect water quality of public supply wells (PSW) is important because of the strong influence of land use on water quality, the rapid pace at which changes in land use are occurring in some parts of the world, and the large contribution of groundwater to the global water supply. In this study, groundwater flow models incorporating particle tracking and...

TRACERS IN GROUNDWATER: USE OF MICROORGANISMS AND MICROSPHERES bacteriophages (bacteria-specific viruses), often referred to simply as phages, were employed widely as tracers in groundwater applications. A modest number of phage tracer experiments involving groundwater systems were conducted in the 1970s and 1980s. Most notable were transport studies involving the use of an Aerobacter aerogenes...
