“…Interpolation forecasts values for cells in a raster from a restricted number of sample data points. It can be used to forecast unknown values for any spatial point data, such as elevation, rainfall, chemical concentrations, and so on [25]. Several interpolation techniques are often used in the atmospheric sciences such as inverse distance weighted (IDW) and kriging [26].…”

“…Although it is important to verify the results of the EPIK method using tracer test, it is not always feasible to obtain such measurements. In individual cases, adaptations regarding the local test site have to be made, which was observed in the study of Moreno-Gómez et al [12], Momejian et al [33] and Loborec et al [14].…”

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.

“…Thus, it is necessary to consider criteria associated with these problems, so it would be ideal to use the land use criterion as the main factor that directly influences the vulnerability degree to aquifer contamination, since urban infrastructure works as a waterproofing, reducing infiltration and increasing pollutants [8] and has a direct influence on recharge and infiltration [9]. Likewise, it is proposed to consider specific problems for coastal areas, such as climate change [10], [11] and incorporate criteria such as the rise of the sea [12] and the distance respect to the coastline, because of contamination can also occur on a horizontal plane [13], [14].…”

The present study proposes four factors for the construction of a vulnerability index in relation to the pollution of coastal aquifers in urban karst areas. It considers three environmental factors (climate, relief and rise in sea level) and one anthropogenic (use of land), with greater importance given to the latter, as the intention is to work with the premise of being a built-up area, as is the case with Playa del Carmen, Mexico. For each factor, the following variables were considered: (1) Relief: frequency of depressions and form type, depending on their morphological features; (2) Climate: with the Modified Fournier Index; (3) Rising sea level: with the modelling of sea level rise, potentiometric surface level and distance from the coast; and (4) Use of land: differentiated by the secondary zoning of the urban development program and land population co-efficient of occupation. For the relief factor, the most vulnerable areas were identified at the north and southern extremes of the urban area with a frequency of 30 to 37 depressions and a predominance of sinkholes and sinkholes-uvalas. The Modified Fournier Index is from 198.46 to 200.74, with a distribution of high vulnerability to the south-east; the land use factor shows high to very high vulnerability distributed throughout most of the city. a sea rise projection of 1 to 3 m is identified in the first 2 km with respect to the coastline, at a distance from the coast of 1 to 3 km and a constant potentiometric surface level for the entire study area. Finally, the uses are designated as commercial, residential tourism, high housing and mixed uses.
