Is the Buda'ah well Hadith in which dead animals, filth was thrown accurate?

https://sunnah.com/abudawud/1/66 Narrated AbuSa'id al-Khudri: The people asked the Messenger of Allah (ﷺ): Can we perform ablution out of the well of Buda'ah, which is a well into which menstrual clothes, dead dogs and stinking things were thrown? He replied: Water is pure and is not defiled by anything. (Sahih by Al-Albani) Also https://sunnah.com/abudawud/1/67 Reading this it does not seem right that the water is pure?
