The Water Body Of Water

Eutrophication is a concern in the Chesapeake Bay. Eutrophication is caused by excessive amounts of nutrients. Excessive nutrients in the bay have negative effects on the bay's ecosystem. The extra nutrients make the environment unbalanced. The extra nutrients cause a chain reaction that eventually kills most of the organisms in that area. This is what is known as a dead zone.

More than 24 billion gallons of untreated sewage waste and storm water are pumped into the lakes annually. Pollution is increasing as well, due to the cottage development, where people enjoy spending their summers relaxing. For many years, the lake habitats have been affected by pollution and habitat destruction. The market for fish is tremendous; so much so, that we have depleted our fishing resources, and have had to market on invasive species.

-The more dissolved oxygen in the water, the more fish is observed in that area of water.

The eutrophication test tested if the creek has too many nutrients. If we found high levels of phosphate and nitrate in the water, that would mean the creek has eutrophication, which is bad. Phosphate and nitrates are found in fertilizers, and some detergents. On average, we found out the creek had .1% phosphate in it which is good.We, also, found out that was .9% nitrate in the creek, which is also good. The dissolved oxygen test tested how much oxygen was in the water. We found a 9.8% average for dissolved oxygen, which determines the type and number of macroinvertebrates that may live there. In past years it was tested that the water was warmer. The velocity of the water could affect this. As a result, I conducted the river does not have eutrophication.

Eutrophication is when there is too much nutrients in the water, as stated above. Eutrophication can come from farmers fertilizing their fields and some detergents. We tested for phosphates, salts or ester of phosphatidic acid. We also tested for nitrates, salts or ester of nitric acid. The more the phosphates and nitrates, the more eutrophication is present in the stream. We tested for dissolved oxygen, the amount of oxygen in the water, as well. We found found a very low level of phosphates with an average of 0.1 parts per million (ppm). We also found a very low level of nitrates with an average of 0.9 ppm. The dissolved oxygen level was 9.8 ppm. The higher the velocity of the water, the more dissolved oxygen it will contain. All of these measurements are very good and show that there is little or no eutrophication in the

This year I went on a field trip to the Conodoguinet Creek. This creek runs into the Susquehanna River and drains 500 square miles of diverse landscapes. Conodoguinet comes from an indian word meaning “a long way with many bends.” It begins near Carlisle at North Middleton Park and comes to an end in West Fairview, when it flows into the Susquehanna River. The Conodoguinet Creek is about 90 miles of bends and loops that meander throughout Cumberland Valley. When I went on this trip, I tested how fast the water was moving downstream. I also tested the creek for the acidity and eutrophication. Eutrophication is excessive richness of nutrients in a lake or other body of water, frequently due to fertilizer runoff from the

Water is an important resource and weather agent in our world, and the Great Lakes Region has an intimate relationship with water. The region was shaped by glaciers long ago and continues to be shaped by flowing surface water today. Groundwater is very pure in the area, which allows for plants, animals, and humans to thrive there. Migration into the area can be related to the groundwater found there. Human use of the water results in man-made structures, water flow alteration, and changes in water quality. Water is very influential in the Great Lakes Region.

There are innumerable sources of pollution to the Chesapeake Bay creating serious water quality issues. Run-off and discharge from natural, industrial and municipal sources causes nutrient overload, resulting in algae blooms. The algae blocks out the sun, which prevents native aquatic grasses from surviving. As the blooms die, they deplete the water of oxygen which is essential to the survival of all aquatic animals.

In this paper I will examine multiple perspectives in an attempt to understand the recent eutrophication of the Chesapeake Bay. Our textbook, Cambell Biology defines eutrophication as a process in which nutrients, usually phosphorus and nitrogen, are unusually present in a body of water, leading to algae blooms and accelerated growth. Anoxia is a condition in which areas of water are severely depleted of dissolved oxygen.

This has led to a doubling of phytoplankton biomass and cyanobacteria, also known as blue-green algae. Phosphorus concentrations are three times higher in the south basin than in the north. As well as the nitrogen concentration is slightly higher in the south than the north. The concentrations typically gather at the south end of the lake and decline as it moves north, this is likely the cause of the Red River flowing inward.

When talking about nutrient content and nutrient type in bodies of water (especially lakes), three terms help identify these types of bodies of water- oligotropy, eutropy, and dystrophy. Eutropy refers to the probably the best possible condition for a body of water, because this type of body of water has many nutrients available to it (often in the form of silt) such as phosphorous. These bodies of water are usually near farms or forests and are thriving with life. Algae is a common type of organism that grows in eutropy’s, but can serve as a problem for the survival of other species. Oligotropy is basically the opposite of eutropy condition wise. Oligotropic bodies of water usually have a small amount of organic matter, few nutrients, and especially lack phosphorous. These water bodies are often near terrestrial ecosystems. Dystrophy refers to the condition in bodies of water that have an abundance of organic matter- so much so that the water is often brown. These bodies of water are often near bogs. Lakes can gain these types of nutrients through things such as runoff that bring soil nutrients into the water;

The limiting nutrient in a water source is what controls algal growth, no mater how much other nutrients is present, without that nutrient there will be no growth. In this regard it is imperative to know what the limiting resource is in a drinking water system in order to maintain the health of the system. Since phosphorous is naturally found in small quantities in water, if too much phosphorous is present then algal growth will increase. Having such high levels of algal growth can dramatically affect the lake’s health, and can effect how a municipal government must treat its water. The

Many animals and insects live in and on the water surface such as bugs, dragonflies, spiders, snails, fishes,...

This pollution has had a negative effect on the plant and aquatic life of the lake. The amount of phytoplankton has increased, “although the number of species has decreased. The number of individuals per liter of water increased from a few thousand in the 1950s, to around a hundred million in the 1980s, up to several billion in the 1990s.”[4] This is in direct relation to the amount of phosphorus in the water which promotes algae and plankton life to exist. The same trend that was shown with phytoplankton can be seen by zooplankton in that the number of species decreased while the amount of them increased. The amount of zooplankton increased from around 2,000 to around 23,000, from 1950 to 1980, respectively. [4] The loss of indigenous fish life has been seen over the same time frame but another factor might have played a bigger role than the lake eutrofication, this factor is that the lake was introduced with a number of exotic species that have become dominate over the indigenous ones.

Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.
