TNAC Presents Water Quality and Testing Part 3: Nitratesby Trumbull Nature and Arts Center on 07/31/20
This video features the nitrate test. The more nitrates there are in a body of water, the more polluted that water is. The water may be undergoing eutrophication, which results in oxygen depletion. This process can cause algal blooms which use up all the oxygen, leaving none for marine life.
