Fate, Transport, and Exposure of Emerging and Legacy Contaminants in Karst Systems: State of Knowledin the subsurface, many contaminants move along and spread across flow lines, interact with media and environmental compartments, and react with chemical and biological entities. All of these processes occur within a highly dynamic and heterogeneous framework that affects the mobility, persistence,MURKY 发表于 2025-3-25 11:39:00
Puerto Rico’s Karst Protection—Beyond the Laws and Regulationsrrent anthropocentric views on Laws and Regulations and their limitations. The main objective is to take a hard look at those ideas, on which laws and regulations have been based, so that we can consider new ideas from new perspectives, and start thinking outside the box.

Trace Metal Accumulation and Re-mobilization in Phreatic Karst Conduitshat allows metals to accumulate, similar to air-filled caves, but are more susceptible to reducing conditions following floods because oxygen is limited to dissolved concentrations. If sufficient reactive organic carbon is transported into the aquifer, oxygen consumption will lower Eh and mobilize mModicum 发表于 2025-3-26 01:48:51
Evaluation of Spill Response System for Mammoth Cave National Park Using Quantitative Dye Tracer Stund transport mechanisms from the surface into the caves and to ensure that the materials and size of the dams are sturdy enough to hold back a spill.

Investigating and Remediating Contaminated Karst Aquifersthe significant heterogeneity and anisotropy created by the existence of open and plugged ramiform conduit systems, but is also a result of the existence of an overlying epikarst. Even more intractable is the effective remediation of contaminated karst aquifers for basically the same reasons. The didegradation 发表于 2025-3-26 15:16:15

Water Tracing Tests and Public Health in Karst Areasions between points where water sinks and reappears in springs and wells. Quantitative monitoring of tracer concentration at the resurgences over time can also help predict the rate of movement of contaminants or pathogens through the aquifers. Tracer tests have been used to document the source of w
