“…The main advantages of these techniques are determining linear flow velocities and information on contaminant transport and delineating catchment areas. Although obtained information and data from tracers are often reliable and unequivocal, limited applicability in large areas with long transit times and also change of color and toxicity concerns are some of the disadvantages of using isotropic techniques and artificial tracers (Goldscheider et al, 2008; Jones and Banner, 2003; Morales et al, 2017). Reviewing the literature, it seems like the use of tracers has been more frequent and beneficial for understanding the interconnectivity between SW and GW in karst terrains compared to other field methods (Katz et al, 1997), for example evaluating the connection between sinking streams and down-gradient springs.…”

Karst aquifers, capable of storing and transmitting large amount of water, are the main source of drinking water in many regions worldwide. Their excessive permeability leads to an enhanced vulnerability to retain and spread the contamination accordingly. From sustainability perspective, the environmental, economic and social impacts of karst contamination on water resources management are gaining more attention. In this study, an overview of hydrogeological processes and concepts regarding groundwater flow and contaminant transport in karstic systems is presented, followed by a short discussion on surface water and groundwater interaction. Due to the complexity of karstic systems, different approaches have been developed by researchers for investigating and understanding hydrogeological processes and groundwater behavior in karst which are reviewed herein. Additionally, groundwater contamination issues and the most common and effective remediation techniques in karstic terrains are discussed. Lastly, modeling techniques and remote sensing methods, as beneficial and powerful tools for assessing groundwater flow and contaminant transport in karst terrains, are reviewed and evaluated. In each section, relevant research works conducted for Puerto Rico are discussed and some recommendations are presented to complement the ongoing hydrogeological investigations on this island.

“…In general, broken rocks of fault in karst formations have good permeability. Some researchers consider that karst conduits can form more easily in this area [13,36,37]. The high topography northern to the Jiuzi Sea cannot prevent the recharge water from going northward, which might be attributed to that the F 2 goes through the topography watershed.…”

The Ancient City in Lijiang of southwestern China was endowed as World Cultural Heritage by UNESCO, and the karst springs located in Black Dragon Pool are its main water source. However, the springs have dried up several times in recent years, which caused serious damages to the landscape as well as the city water supply. Triggered by the dried-up event in Black Dragon Pool, a long-distance artificial tracer test up to 17 km was employed to investigate the karst conduit network distributing in the study area. Based on the tracer concentration breakthrough curves (BTCs), the hydraulic connection from the same injection point (located in a giant depression named the Jiuzi Sea) to the springs on both sides of the topography watershed was proven, and the conduit structure was discussed. According to the characteristics of BTCs and considering the low tracer concentration and tracer recovery, a conceptual structure of leaky reservoir with threshold effect above a certain groundwater level was established to interpret why the springs in Black Dragon Pool dried up several times in history, but those in the Ancient City never did. Furthermore, a method of injecting surface water into the Jiuzi Sea to raise the groundwater level up to the height of Black Dragon Pool was proposed to restore the springs. Our study provides insights into the long-distance artificial tracer test, and opens a new avenue for groundwater resource recovery of this Ancient City.

“…Although it may seem at first glance that our model is ill-posed, it provides a better understanding of groundwater flow system in the study area. Of course, the amount of available data for this study is small compared to a few other groundwater modeling studies in karst terrain (e.g., Morales et al, 2017;Xu et al, 2015a). However, the basic hydrogeological framework and most crucial data such as spring discharge and breakthrough curve are available for this site.…”
