how long can water sit outside before it become stagnant?

Answer 1

It really depends on the region and where the water is located. In the upper latitudes or in winter, water can sit for many days and still be drinkable, as there are very few insects around and bacterial growth is very slow (not to mention that when it's cold enough, the water will freeze anyway). In the tropics, the water won't even last a few hours until it becomes a breeding ground for mosquitos. Generally, unless you live in a very cold area, if you're going to drink the water, it's a bad idea to leave it standing still outside in an open container for any amount of time, even for just ten minutes, since if nothing else dust or pollen or any number of contaminants can fall into it.

Answer 2

It observed "lobster" & picked this, yet you have got replaced the class. i'm very white too & I won't stay out for greater desirable than half-hour devoid of sunscreen. With goo sunscreen i will stay out for hours (in all probability a foul thought).

Hi. The water its self does not change, only the materials dissolved in it or in suspension. This can be a day or two or sometimes, as in the case of a spring, never.
