“…Due to the fact that the EPIK method is designed for application in karst aquifers, it is developed and adapted specifically for these regions, but might be incongruous for porous or fissured rock aquifers [27]. In addition to that, the EPIK method is an easy to use tool, which delivers fast results [30]. This, however, could mislead one to a so-called "rapid assessment", where users of the method do not consider wisely, which could result in serious errors [23].…”

“…On a test site in Yichang, in Hubei Province, SW China, only the EPIK method has been applied, but results have been validated using tracer tests [29]. Contrary to the successful application in China [29] and Brazil [30,31], the use of European methods to the Mexican Yucatán karst has shown that the applied methods need more adaptation for the local karst system and do not correspond with regional characteristics. The applied methods include EPIK, COP, PI and PaPRIKa.…”

“…Due to its practicality, various studies have shown that this EPIK method can be an important tool for vulnerability assessment. In addition to that, the EPIK method is an easy to use tool, which delivers fast results [30]. Although it is important to verify the results of the EPIK method using tracer test, it is not always feasible to obtain such measurements.…”

A more detailed overview of the differences between the significant studies is presented in the studies of Ravbar and Goldscheider [8], Younos et al [37], Iván and Mádl-Szőnyi [26] and Lenhare & Sallun Filho [30]. A summary of the case studies mentioned in this work is provided in Table S1.…”

Groundwater Vulnerability and Risk Assessment in A Karst Aquifer of Greece Using EPIK Method

et al. 2019

The aim of this study was the assessment of groundwater vulnerability and pollution risk of the Perivleptos karst aquifer in the northwestern part of Greece. Hence, the EPIK method has been applied within the study area. Additionally, a detailed literature overview has been obtained, including the worldwide application of the EPIK method. The hazard map has been developed for the implementation of risk assessment. The resulting vulnerability map was divided into four classes and showed especially high to very high vulnerability. The subsequent hazard assessment has shown mostly low to moderate endangerment for the northern part of the study area, which is mainly covered by forest, while the areas covered by urban and industrial, as well as agricultural land, use primarily show high to very high endangerment. Concluding in the risk map, the study area consists of 13% of very high, 48% of high, 36% of moderate and 4% of low risk of contamination. According to the literature overview, the EPIK method was mostly used in combination with other vulnerability assessment methods, and results have been validated through tracer tests, sensitivity analysis or comparing to other methods. In this study, an additional single parameter sensitivity analysis was obtained for validation of the EPIK parameters.

“…Ribeiro et al (2016) applied the EPIK methodology to the Sapucari and Maruim karstic aquifers, which are important underground water reserves that supply the municipalities with the same names and the large city of Aracaju in Sergipe. Lenhare & Sallun Filho (2019) applied EPIK in the south of São Paulo state, in the Guapiara plateau region, where the authors identified vulnerability with a low association with the high population, and in the Serra of Paranapiacaba where vulnerability was high but associated with low population. Pereira et al, 2018, presented a validation of the intrinsic vulnerability map of the São Miguel River Basin (MG), elaborated using the EPIK methodology.…”

Protecting groundwater in karst aquifers is extremely important. Vulnerability maps can greatly help proper decision making based on physical environmental attributes that influence how easily a contaminant applied to the land surface can reach groundwater due to anthropogenic activities, and the properties of the contaminants. Methods for determining vulnerability based on the COST Action 620 Approach, when applied in the study area, may lead to contradictory results. The main purpose of this study is to provide an overview of academic research on intrinsic karst aquifer vulnerability methodologies applied in South American and Caribbean countries. Secondly, it describes studies related to karst aquifers that, in some cases, lack specific information on intrinsic vulnerability. The objective is to encourage and to help develop specific methods for determining karst vulnerability in these regions. To achieve these purposes, a systematic literature review was conducted including studies conducted at institutions such as universities, national water institutes, and by geological services. Several methods have been used in the region such as COP, DRASTIC, RISK, EPIK, PI, PaPRIka, and the Slovene Approach. And some attempts have been made to develop a specific methodology that best suits the specificities of the region’s karst aquifers. South America and the Caribbean have almost 5 % of the world´s carbonate rocks. Some countries have large extensions of their territory covered by karst rocks, such as Peru, 15.4 %; Cuba, 67 %; and Mexico 25.29 %. Estimates indicate that more than 10 million people use water from karst systems in Mexico. In Cuba, 33 % of all available water volume originates from groundwater, and 91.51 % from karst aquifers. In Mexico, 13 studies have been conducted on the importance of karst aquifers, which mostly address the Yucatan Peninsula, followed by Brazil (9 studies), Cuba (5), Colombia (1) and Peru (1). Information about the theme is scarce in most of the other countries in the region. Some studies have incongruent results given the regional characteristics of tropical karst.
