Groundwater usage in the world is widely reported to increase because of the uncertainties attached with the availability of surface water. Groundwater resources are looked upon as the alternate source of freshwater on account of its widespread and continuous availability in proximity to the point of use or living place, less vulnerability to contamination and low cost of extraction in both urban and rural area of developed and developing countries of the world. Such a scenario has led to the degradation and depletion of groundwater resources in many parts of the world. The study area, Coimbatore district, is a rapidly urbanizing and industrializing city in the southern part of India which relies upon the groundwater resources for meeting the agricultural, industrial and domestic requirements. In view of this evaluation of groundwater resources and an understanding of the vulnerability of the aquifer to contamination become essential for the effective management of groundwater resources. The vulnerability of the groundwater to contamination is assessed using DRASTIC and Pesticide DRASTIC index in the GIS environment. The study showed that the high vulnerability areas are characterized by shallow water table of less than 4 m, gentle topography, sandy loam soils, thinner vadose zone and underlying geologic formations with well-developed fissures and fractures.

“…Consequently, groundwater pollution has extremely become a severe problem, particularly in areas where fertilizers are widely used in farmlands. The quality of groundwater supplies is as important as its quantity; hence, it is wise to take proper attention in the quality of groundwater [2][3][4]. The protection of groundwater contamination is important in the managing of groundwater resources and the evaluation of aquifers vulnerability [5].…”

The increasing use of chemical fertilizers, with spreading industrial and urbanization activities in the whole area of the Basara basin expected to affect the quantity and quality of water from these sources of pollutants. The main aim of this research revolves around the integration of the intrinsic vulnerability Index (VI) through applying the pesticide DRASTIC method, with the irrigation quality index, to assess the irrigation susceptibility Index (SI) for the basin. The quality of groundwater for its suitability for irrigation purposes was measured by its hydro-chemical parameters in this research. Thirty-one water samples were collected in the studied area during the post-monsoon period of the year 2018. Samples have been tested for both physical and chemical parameters. The Geographic Information System (GIS) has been used for this assessment. The results indicate that water movement directions of streams, the geological formation of aquifers, land slope, and contamination sources have a great impact on water quality, vulnerability, and susceptibility index. The pesticide DRASTIC map categorizes the basin into five classes as (very low, low, moderate, high, and very high). Results show that the most vulnerable area to pollution is those that used for intensive agricultural and industrial sectors, besides the areas with high permeability and lands with minimum surface slopes which are intensively used as cultivated areas. The results indicate that the incorporation of both hydrogeological and hydro-chemical datasets enables more realistic evaluations than those of an individual dataset to estimate the groundwater contamination susceptibility of an aquifer. This work offers the decision-makers a clear photo of the quality of irrigation water and the area most vulnerable to contamination. This will be used as the basis for future research to mitigate the effects of vulnerable areas and to establish a new groundwater management strategy in the basin.
