My office is next to a Gas station, the underground container which stores the petrol was having a leakage for quite some time and was detected and fixed later. The issue is that the underground water got mixed with our office ground water(bore water), and still the water withdrawn from borewell contains the smell of petrol, tastes like petrol and also the color of water has turned slight yellowish.
My questions are,
1. can this contaminated water be used for performing wuzu, or used for making things clean (washing or for doing taharat/make this paak), can this water be considered paak ?
We have been getting this water from past few years at our office and we have been using the same water daily for wuzu and taharat.
2. We have also been offering salat/namaz by doing wuzu with same water. So in this case, if the water is muzaf(contaminated) then the salat/namaz performed by us at office will it be Valid? or do we have to perform prayers again(ayadah for the same).
It will be highly appreciated if you people provide me the reference for this issue as well.
