Groundwater, water from wells.

• gambiting 3y ago
  In 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.

  Which is also polluted with pesticides and other agricultural pollutants.

    Not 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).
