The High School Students at Bellport Academic Center are concerned about nitrogen and phosphorus in our water. We think clean water is an important part of a green Long Island. We have a bay tank, we are testing the water for oxygen, nitrogen and phosporus and observing the food web for stress. We are also going out into the field and testing the Patchogue River. Our results can be seen at www.liwatersentinels.org . We are the Patchogue Partners. Click data.
