Dear Researchers!
It is known that methods such as: GOD (Foster) and DRASTIC (Aller et al) and others are widely used. But are there new methods developed to evaluate the intrinsic vulnerability of the physical environment to loads or pollutants? and with easy application (accessible parameters)?
DRASTIC method is the best and widely using to assessing vulnerability and GIS also used to giving weight-age of contaminated pollutants
Well,
Let's look at the link

Dear Leônidas
You can find more information to your question in the attached articles.

Dear Leônidas Luiz Volcato Descovi Filho ,
There is no method that can fit every case of study. DRASTIC request several factors that are not available in many countries; the spatial resolution of data is another problem. GOD is made for aquifers that have a large extension; it is not the best solution for small aquifers or where lateral and vertical lithological variations are frequent. SINTACS is the italian little brother of DRASTIS; it has thus the same shortcomings. AVI is based on permeability which is generally not available or the measurement points are poorly distributed...
Since geophysical data are mostly available or surveys could be done, we suggest a geophysical method for countries where data are lacking.

Yes, Mr Adil Salhi ; DRASTIC is the best
I worked in my research by DRASTIC and SINTACS but I do not know why the results of DRASTIC are more significant than SINTACS
do you steal explain me

Dear @Rachid Zegait,
When you say DRASTIC's results are more significant I understand that you made some kind of validation study so you can correlate it with the results of vulnerability modelling. Else, it is mostly subjective.
Anyway, even if both methods consider almost the same factors, yet there are many differences between them in weights, intervals and mainly in the conceptualization.
Besides, fequently, our prediction affects the way we perceive and understand results.

A GIS based DRASTIC model for assessing groundwater vulnerability is mostly used
Hello,
Assessment of potential impact of pollution requires effective vulnerability estimates. A modified DRASTIC approach using geographic information system (GIS) was applied to evaluate groundwater vulnerability in several regions in the world.
