Answer:Artision wells
Answer:
No water source is 100% certain to be pure. Surface water from run-of would likely be the most chancy. shallow groundwater next. At the other end of the scale deep groundwater (artesian wells etc.) and glacier derived water (because it represents water from rain/snow that fell several hundred years ago) is probably safest.
Pollutants can be classified into point source pollution and nonpoint source pollution. Point solution originates from a single source. Nonpoint polluattion has no single source from where it can be traced.
Some Primary pollutants are like when humans directly put them in the air Secondary pollutants are like when pollutants react with Primary and other Primary pollutants.
Point Source Pollution
Primary air pollutants are emitted directly into atmosphere from a process such as exhaust from a engine, industries, volcanic eruption Secondary air pollution are formed in the air when primary pollutants interact.
This is because the pollutants that are emitted from a direct source are not limited to the same area, they can be found far and wide, therefore affecting other places
The leading source of pollutants found in rivers surveyed for the 1998 report was agriculture.

Primary pollutants are pollutants that enters the air directly from a source and Secondary pollutants are air pollutantsproduced by the reaction of a primary pollutant with some other pollutant

no it isn't, it is a point-source pollutant
The surface is warmer than the air above it, causing upward refraction.
they contain a high source of grundya they contain a high source of grundya
Because surface water has all the impurities and refuse/waste from animals and other pollutants. These are removed by filtering through the soil and rock formations below ground. The further down you go, the cleaner the water becomes. Waste in sewage is filtered in a similar way at treatment plants. They use sand beds to remove the majority of pollutants.

Point Source Polluters
point source pollutants, meaning they come from one source. i like pie
