Both are washed off the land into streams whenever it rains, but nitrogen dissolves in water, so it also soaks down into the soil, ultimately reaching the water table.

Using a computer model to simulate ground-water flows, USGS scientists found that when nitrogen from fertilized farm fields soaks into the ground, it takes 20 to 40 years on average for the nutrient-laden water to make its way underground into streams and rivers.

Delavan Lake Dredging Clears Natural Filter - In the late 1980s, Delavan Lake turned into an algae soup by mid-summer that discouraged swimming, clogged boat motors and killed off game fish. Farm and residential development around the lake poured nutrient-rich runoff into the watershed and into the lake. Those nutrients fed the algae blooms. Today, a project to redredge the channel in the narrow inlet which was designed to store and collect the sediment flowing into it before it reaches the open water.
