Purification of Polluted Well

There are five ways of cleaning a well:

If dirt of any kind falls in to the well, draw out the dirt and the whole water from the well to make it clean and purify.

If a human being, animals like pig, dog or a goat, two cats or any other animals as large or bigger than these, falls in the well and dies there, all the water must be taken out.

If an animal with blood flowing in its veins, falls in the well and inflates or bursts in the water of the well, the whole water should be impure and it should be taken out whether the animal is big or small.

If one pigeon, a hen, a cat or any other animal of same size falls into the well but the animal does not inflate or burst, then 40 buckets of water are enough to be drawn out.

If a rat, sparrow or any other living thing of the same size falls and dies in the well, 20 buckets of water are sufficient to be drawn out of the well.
