The Case of a Well and Things that May Fall in It (Fatwa best explains Ahadith 2-12 as well as the following chapter.)

2ـ وَبِهَذَا الإِسْنَادِ قَالَ مَاءُ الْبِئْرِ وَاسِعٌ لاَ يُفْسِدُهُ شَيْ‏ءٌ إِلاَّ أَنْ يَتَغَيَّرَ بِهِ.
2. Through the same chain of narrators as the previous Hadith the following is stated: “He (the Imam) ‘Alayhi al-Salam, said, ‘Well water is vast. It does not become polluted until it is changed.’”
