Each student will give a recorded presentation to the class on their selected water pollutant.  The presentation should be between 60 and 90 seconds and should include easy to read visual aids.  This presentation will be recorded and posted on this website for all students view.  There will be a CP on the pollutants presented; every student is responsible to know about ALL pollutants, including presentations from the other class (a.m. responsible for p.m. and vice-versa).  A failure to pass this CP will result in revoking the opportunity to travel to Coon Creek in Armada for on-site water quality testing.  

The presentation should include a thorough definition of the pollutant, the source of the pollutant, the negative effect of the pollutant, how to test for the pollutant including demonstrating any Hach equipment we have available, and possible methods to remove the pollutant.

The safe levels of dissolved oxygen in drinking water falls between
6mg/l and 12mg/l
However too low is not dangerous to humans

Less than 4 grains per gallon is considered to be soft.
4-7 grains per gallon is considered to be moderately-hard.
7-10 grains per gallon is hard.
Greater than 10 grains per gallon is very hard.

In most situations there is very little soluble P in the soil at any point in time. It has been estimated that at any point in time, the solution/available forms of P in many soils may only amount to from 0.01 to 0.06 ppm (0.02-0.12 lb P/acre). This P will typically move no more than about one tenth of an inch in the soil. Roots quickly deplete the 0.10 inch cylinder of soil around each root and must continually grow into new areas of the soil to maintain adequate P intake.
