Ground wa ter vul ner a bil ity based on four dif fer ent as sess ment meth ods and their quan ti ta tive com par i son in a typ i cal North Eu ro pean Low land river catch ment (the Pliszka River catch ment, west ern Po land) The as sess ment of ground wa ter vul ner a bil ity is a cru cial part of plan ning and wa ter man age ment be cause it can iden tify areas where aqui fers are more sus cep ti ble to con tam i na tion. De pend ing on the vul ner a bil ity as sess ment method, the re sults can dif fer sig nif i cantly. Con se quently, dif fer ent meth ods can pro vide am big u ous in for ma tion that could fur ther in flu ence de cision-mak ing pro cesses in plan ning or wa ter man age ment. For the Pliszka River catch ment, the in trin sic ground wa ter vul nera bil ity of the up per most aqui fer was es ti mated us ing four dif fer ent meth ods: DRASTIC, GOD, and two meth ods that are based on em pir i cal for mu las of wa ter res i dence time in an un sat u rated zone. The in put data in clude a se ries of the matic maps sup ple mented by 1,322 shal low bore hole pro files and lab o ra tory tests of sam ples col lected in the course of field work. The col lected data were pro cessed in GIS soft ware, and the re sults of each method were mapped in high res o lu tion. The result ing maps of ground wa ter vul ner a bil ity were then quan ti ta tively com pared to val i date their ap pli ca bil ity for the as sess ment of ground wa ter vul ner a bil ity in a typ i cal North Eu ro pean Low land river catch ment. The maps gen er ated by the DRASTIC and GOD meth ods are dom i nated by ar eas with mod er ately high (54.6 and 48.4%, re spec tively) and mod er ate ground wa ter vulner a bil ity (32.7 and 32.3%, re spec tively). No ar eas of high ground wa ter vul ner a bil ity are pres ent. One of the wa ter res i dence time meth ods pro vides re sults sim i lar to the pre vi ous meth ods at the catch ment scale, and one method yields high groundwa ter vul ner a bil ity val ues for the ma jor ity of area.

Abstract. Groundwater Pollution risk (GPR) map which utilized groundwater quality is important in order to prevent the groundwater contaminant concentration due to the agricultural activities. DRASTIC model and GIS application are two important tools that had been used for accessing and predicting the quality of groundwater. These supplementary tools are calculating, visualizing, and presenting the GPR by using DRASTIC index for each hydrogeologic factor through ArcGIS software. This study was covered approximately Selangor basin area where the GPR has been defined. There are four categories of agricultural activities in the Selangor basin which are animal husbandary areas, horticultural lands, short term crops and tree, palm and other permanent crops. The map showed that the "low" zones of GPR occupied 56% of the east side of the Selangor basin, 34% of the west side of the Selangor basin exposed to "medium" zones of GPR and the "high" zones of GPR covered 10% at the north side and the south to the west side of the Selangor basin. As a particular, for agricultural activities which is 52% of Selangor basin area, the "low", ''medium" and "high" zones of GPR was occupied as 42%, 43% and 15% respectively. Based on four categories of agricultural landuse, GPR map validated by nitrate distribution map, shows that the 99% of the variation in nitrate distribution zones are explained by GPR zones. In conclusion, groundwater pollution risk was affected by agricultural activities.

“…A avaliação de uma menor quantidade de parâmetros característica do método GOD, não implica diminuição na abrangência da análise (Vías et al, 2005). Por exemplo, o processo de recarga é avaliado, individualmente, no método DRASTIC, enquanto que, no método GOD, está incluído no âmbito da classificação dos estratos de cobertura, quando se dá ênfase à ocorrência de fraturas bem desenvolvidas que podem favorecer o fluxo preferencial, reduzindo, substancialmente, a atenuação dos contaminantes, sendo fator crucial para o aumento da vulnerabilidade.…”

The main object of this research is to classify the groundwater vulnerability to contamination in a limited (Foster & Hirata, 1988) (Foster & Hirata, 1988), que consiste na caracterização, por meio de índices, do grau de confinamento da água subterrânea, da ocorrência dos estratos de cobertura e do nível do lençol freático. O resultado final é obtido pela multiplicação dos índices e corresponde a um mapa geral com indicação dos níveis de vulnerabilidade da área. Os resultados, em termos percentuais, revelam que a área apresenta vulnerabilidade à contaminação predominantemente variando de média (41%) à alta (59%), evidenciando a necessidade de desenvolvimento e implantação do zoneamento de proteção do manancial.
