Atmospheric deposition.
If there are chemicals from fertilizers, like nitrates or phosphates, in your well water...
It's a point source pollution if you see where it came from.
It's a non-point source of pollution if no sources around.
What can happen if fertilizer gets into streams or lakes when water runs off after it rains?
Plants such as algae can grow out of control.
Chemicals such a DDTs & PCBs can get into the fish.
The water can get too warm.
Once the oxygen is depleted from a lake why does the water become toxic?

When water goes into an aquifer, it is called
discharge
remediation
recharge

discharge
depletion
recharge
remediation

recharge
discharge
depletion
remeditation
When contaminated groundwater is treated, removed, or contained
depletion
discharge
contamination
remediation
Why is remediation not the best way to deal with water pollution?
More than one answer
it's expensive
there's not enough workers to clear it out
because a lot of mistakes can be made cleaning it up
it won't completely remove all the contaminants
One way sinkholes are formed
when people pump too much water from the aquifer
when water dissolves limestone in an aquifer or caves
when more water is taken out of the aquifer than pumped into it
when someone doesn't pay their dirt allowance bill
