In short, certain areas have radioactivity, which can contaminate ground water, even long after surface water has regenerated itself. Even floods, sink holes-all kinds of things, can cause water to become contaminated. Surface water can be contaminated easily, by farmers' chemicals, oil from vehicles, including watercraft. Anything that contaminates can get to surface water.
What else can I help you with?
Why does the soil air contain more carbon dioxide than atmospheric air?
ground water contains more zooplanktons than phytoplanktons this zooplanktons releases co2 during respiration
What is difference between polluted water and contaminated water?
polluted water is more dangerous for use and contaminated water is poisiones then polluted
What do you mean by surface water?
The water on the surface of the ground, or water that is not ground water (water underground) that collects in lakes, rivers, streams or oceans. See the related links for more information.
Why would fish start swimming closer to the surface of the water when its polluted?
As water becomes polluted, oxygen levels rapidly drop. Near the surface, where Air and Water are in direct contract water is oxygenated much more easily than in deeper water. In very bad situations fish will begin to "gasp" at the water's surface which looks like they are trying to feed, but in reality they are trying to get oxygen from the air itself.
Why does ground water often contain more dissolve substance in it than water on the surface?
yes
Is water more polluted then land?
yes
Is salt water more polluted than fresh water?
no
Which is better surface water or groundwater and why?
It depends on the situation. In general, groundwater is better because the earth filers the water. However, if the soil in that region is heavily polluted, the water will also become polluted. Surface water in constantly polluted by animal feces, human pollution, and atmospheric pollution.
Why can you not use water that is polluted for recreational purposes?
The skin is the largest organ of your body. It will absorb things, including water and chemicals. If you swim or fall into polluted water that pollution will seep into your body. The more time you are in contact with the polluted water, the more pollution will be absorbed by your body
Where does surface water travel?
Surface water flows downhill or seeps into the ground becoming groundwater. The natural flow of surface water is downhill or seaward. See the related link for more information.
Why would ground water be more difficult than surface water to clean after contamination with chemicals or microorganisms?
casie it is natrroll
Why have water bills increased?
because more water has been polluted so they have to clean more water which makes the water bills increase
