The Hudson River is the 4th longest river in New York State. The head is located at Lake Tear of the Clouds in the Adirondack Mountains, and the mouth is at the Atlantic Ocean. Because the Hudson River empties into an ocean the water is brackish. That means that the water in the river is a combination of saltwater and freshwater. The Hudson River stretches for 315 miles from north to south through New York State. Between 1947-1977 General Electric (GE) dumped 1.3 million pounds of PCBs in the river polluting it and making it hazardous. Polychlorinated biphenyls, or PCBs, are used as an insulator and a fire preventer. They also can cause illnesses, such as cancer. If the fish take in the PCBs and then we eat the fish, we can get sick.…show more content…
Overall, the more macroinvertebrates in the water, the healthier the stream. pH is a measure of how acidic or basic water is. It is measured on a scale from 0-14. 0 is the most acidic, 14 is the most basic, and 7 is neutral. It is the measure of the relative amount of free hydrogen and hydroxide ions in the water. Acidic water has more hydrogen ions, and basic water has more hydroxide ions. When water’s pH is around neutral (7), that is a suitable and healthy living environment for fish, and indicates a healthy stream. If the water is too acidic or too basic, it can be harmful to the aquatic life. Dissolved oxygen is a measure of how much oxygen is dissolved in the water. As the amount of dissolved oxygen drops below normal levels in water bodies, the water quality is harmed and creatures begin to die off as a result of eutrophication. The higher the level of dissolved oxygen, the healthier the stream. When there is a lot of dissolved oxygen present it makes for a safe environment for fish to live and reproduce. Having all this healthy fish can provide us with food, so overall the more dissolved oxygen, the better. Nitrates are a compound found in fertilizers that is used to help plants grow. It is what is given off as a result of the use of nitrogen in water. The organisms in the soil eat the nitrates and it helps the metabolism and the health of organisms. Plants, such as Algae use nitrates as a source
