I am aware of DRASTIC method which is the widely used method around the globe to assess vulnerability of groundwater to contamination on a regional scale. I need to know some more well known and widely using methods. Kindly suggest me.

i hope..it wl help u..tc
Depending on the geological and aquifer conditions, beside DRASTIC, you can use GOD method introduced by Foster, EPIC method for karts areas, COP method and others. From my profile on the research gate you can also find some methods developed by Ilijovski and myself which used the polinomial approach in definition of parameters range that are incorporated in the methodology.
As the former said, just send to us the right geological and aquifer conditions of your study area, so we can tell you the right method other than DRASTIC

Thank you very much for providing me the article. It's very helpful.

Thank you very much for providing me the information. It's informative and helpful.
As has been mentioned, knowing the geology and the potential source(s) of pollution, DRASTIC, may prove useful. A lot depends on how much information is available and its reliability.

Drastic is a very useful method.

Perhaps, check results of European project COST Action 620 „Vulnerability and risk mapping for the protection of carbonate (karst) aquifers“. COST Action 620 was established to develop an approach for the protection of karst groundwater, which takes into account the characteristics of karst, but which can, however, also be used for other aquifer types. The project was given impetus by the European Water Framework Directive, which provides a common framework for water resource policy and management. The approach is applicable for both groundwater resource and source protection. It comprises methods of intrinsic and specific vulnerability mapping, hazard and risk mapping, and validation. Intrinsic vulnerability only considers the hydrogeological properties of the system whilst specific vulnerability considers, in addition, the specific interactions with particular contaminants. Hazards are sources of contamination resulting from human activities. The synthesis of all those aspects creates risk maps. The new approach was tested in 11 European karst areas, covering a wide range of possible climatic and hydrogeological settings. You will also find a comparison of several methods applied on one aquifer.
A short overview is to be seen on http://www.bgr.bund.de/EN/Themen/Wasser/Projekte/abgeschlossen/F+E/Cost620/cost620_fb_02_pdf.pdf?__blob=publicationFile&v=2

I would bet on physically based definition and criteria for groundwater vulnerability assessment then...
Hello! I believe the following links can provide guidance:

Thank you one and all for providing very useful answers and important source links.
Dear @ Santhosh, there is no ideal method for every case of study. The choice of a method depends on many elements such as the aquifer type, dimensions, lithology, other intrinsic conditions, available data... which are elements that vary from an aquifer to another.
For this, many investigations tried to compare several methods for a specific case to conclude which method is the most suitable for that specific case.
In many years, we have been working on that comparative studies in Spain, Morocco and Tunisia and we conclude that a geophysical method close to AVI is the most suitable in our cases for many reasons.
Please find more explications on this link:

Good luck
I agree with Adil Salhi’s response. No perfect method. Would suggest you look at the methods pointed out by others & then, determine the best method for your particular work (research).
