If the smallest amount of water fell into a flask: Rabbi Eliezer says: the sprinkling must be done twice; But the sages say that the mixture is invalid. If dew dropped into it: Rabbi Eliezer says: let it be put out in the sun and the dew will rise. But the sages say that the mixture is invalid. If a liquid or fruit juice fell into it, all the contents must be poured away and it is also necessary to dry the flask. If ink, gum or sulphate of copper, or anything that leaves a mark, fell into it, the contents must be poured away but it is not necessary to dry the flask.

If insects or creeping things fell into it, and they burst apart or the color [of the water] changed, the contents become invalid. A beetle causes invalidity in any case, because it is like a tube. Rabbi Shimon and Rabbi Eliezer ben Jacob ruled: a maggot or a weevil of the grain causes no invalidity, because they contain no moisture.

If one intended to drink the hatat water: Rabbi Eliezer says: it becomes invalid. Rabbi Joshua says: only when one tips the flask. Rabbi Yose said: To what does this apply? To water that had not yet been prepared, But in the case of water that had been prepared: Rabbi Eliezer says: it becomes invalid [only] when one tips the flask; And Rabbi Joshua says: [only] when one drinks. And if it was poured directly into one's throat, it remains valid.

Hatat water that became invalid, it may not be mixed into the mud since it might become a snare for others. Rabbi Judah says: it becomes neutralized. A cow that drank of the hatat water, its flesh becomes unclean for twenty-four hours. Rabbi Judah says: it becomes neutralized in its bowels.

Hatat waters and hatat ashes one may not carry them across a river on a ship, nor may one float them upon the water, nor may one stand on the bank on one side and throw them across to the other side. One may, however, cross over with the water up to his neck. He that is clean for the hatat may [sail] across [a river] carrying in his hands an empty vessel that is clean for the hatat or water that has not yet been prepared.

If valid ashes were mixed up with wood ashes, we follow the majority with regard to uncleanness, but [the mixture] may not be prepared with it. Rabbi Eliezer says: the mixture may be prepared with all of them.

Hatat waters that have been invalidated [still] defile one who is clean for terumah [by contact] with his hands or with his body. And one who is clean for the hatat they defile neither [by contact] with his hands nor [by contact] with his body. If they become unclean, they defile one who is clean for terumah [by contact either] with his hands or with his body, And one who is clean for the hatat they defile [by contact] with his hands but not [by contact] with his body.

If valid ashes were put on water that was unfit for the preparation, [the latter] defiles one that is clean for terumah [by contact] with his hands or with his body, But to one who is clean for the hatat it conveys uncleanness neither [by contact] with his hands nor with his body.
