-The Middlesex Health Department definitely uses this kind of information to conduct their water pollution control programs. They frequently test surface water for quality and for the amount of sewage in order to know when its important to take action. If they see that an area has a low level of dissolved oxygen due to pollution blocking out sunlight and killing photosynthesizing plants, they can decide whether they need to monitor sewage disposal as well as determine if they need to watch over any possible sources of the water contamination.
-Environment NJ is doing its best to limit the amount of building that occurs near NJ waters. They hope to prevent major roads from being built near water sources. By testing the amount of dissolved oxygen in certain areas of water, they can determine if the water can handle possible pollutants like carbon dioxide which could further alter dissolved oxygen amounts. In addition, they try to limit the amount of pollution given off by industries that could potentially kill wildlife, decrease photosynthesis, and therefore decrease the amount of dissolved oxygen and productivity in an area.
-The NJ Department of agriculture monitors soil erosion and sediments that get into water. It is important for them to monitor the amount of dissolved oxygen because sediments and dirt can limit the amount of sunlight that gets into water, which decreases the amount of photosynthesis and decreases oxygen levels. This affect can be dire to species that live in or around the effected water.
-Fisherman at Union Lake in southern New Jersey monitor the dissolved oxygen count at the lake to determine if that area would be a quality place to fish. They can tell if the dissolved oxygen count is too low then fish will not be able to live there, so testing to see beforehand can save them a lot of time and money by only fishing where there is high amount of dissolved oxygen.
