What are we drinking then ?
- Gasp0de 3y agoGroundwater, water from wells.
- gambiting 3y agoIn a lot of places drinking water is pumped from open air aquifiers(a lake basically) so presumably it contains everything rain does, since it doesn't go through the rock layers.
- shantara 3y agoWhich is also polluted with pesticides and other agricultural pollutants.
- defrost 3y agoNot all wells, mainly those that are in aquafier catchments that include heavy PFA sites and agricultural runoffs, etc. Airports are notorious sources, PFA's were used in fire fighting foams for a decade or more (depending on global location).
- lm28469 3y agoSpring water or water coming from water treatment plants, both of them are very dissimilar to rain water
- kwhitefoot 3y agoAll of which ultimately comes from rainwater.
- lm28469 3y agoOf course, and most of it comes from sea water, it doesn't mean you can drink sea water
- belorn 3y agoUltimately all water comes from the creation of the earth, which in turn got it from space. The ultimate origin is not very useful. If we just want the first step before treatment plants, it depend on location. Generally it is what ever water that is cleanest and cheapest, usually lakes and rivers with the best connection and high flow of ground water. Ground water tend to be highly filtered which lowers the amount of treatment that treatment plants has to do. Rainwater collection is usually not used for drinking water given the high amount of pollution. It can be used in industry/agriculture, or as backup for areas where the ground water is severely limited.
- PeterisP 3y agoThere is a substantial level of natural filtration between rainwater and springwater, so they are not equivalent.
