Floating Wetlands

Introduction: The purpose of this research is to determine whether there has been a change in the overall water quality of the Lake Tarpon Basin, and if so, whether the quality has improved or worsened. The variables that will determine whether the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). The expected changes are lower dissolved oxygen levels (from the already low levels), higher nitrogen levels (from the already high nitrogen levels), and the state qualifications still are not met for nutrients and dissolved oxygen (Levy, Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because the changes in water quality would be due to pollution, which relates to the question “How does human activity lead to the pollution of water stores?” The hypothesis that will be tested is that Lake Tarpon’s water quality will have worsened since the last measurements by Levy, Flock, Burnes, Myers, Weed, and Rivera in 2010.

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.

Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).

Lake Erie is thriving biologically but not in the way one might think. It’s poisoned with toxic algal blooms that grow in the phosphorus-concentrated waters millions of Canadians and Americas alike depend on for drinking water. Unfortunately, this is also not the first time this has happened to the Great, not-so-great Lake.

As a rower who uses Lake Samish as a place to practice every day, I am quite aware of the poor water quality and debris within the lake. Other users and residents of the community around Lake Samish can attest to the fact that something is quite wrong, considering the lake has recently turned from a dark blue, to an obscure brown color. Unfortunately, while in the middle of a race piece a few days back, our boat nearly crashed into a full lawn chair just floating about in the lake. Samish resident David can agree the pollution has increased, as he stated that he and his wife enjoy kayaking on the tranquil waters each weekend. In merely the

Wetlands improve water quality by helping with nearby flood control. The bottomland hardwoods areas contain large amount of nutrient rich soil which is capable of soaking up excess water from floods or runoff. These types of wetlands also contain marshes or swamps where the water is gathered to create a new environment for other

The Title of this essay is called “What is the Major Problems with Pollutants on the Great Lakes”. The essay explains that there is a problem going on in the Great Lakes with people who live around the Great Lakes area in that what they are throwing into the lakes; whether it would be from trash or fecal matter it is all causing major effects on the ecosystem on the Great Lakes, in turn effecting the fish and water we consume. This is not only a major problem for the lakes but also the humans that depend on those lakes.

A major function of wetlands is that they naturally clean the table waters. With the use of microorganisms it is possible to naturally clean the water supply much better than many water purification plants. A benefit of purifying water with the use of wetlands is that not only does it save the taxpayers money but it also saves the environment from the pollution that a water purification plant would produce. Another function of wetlands is its storage ability. In the event of a large storm or heavy rain wetlands can store the floodwaters so that they do not over run the near by area. To reduce the effects of flooding wetlands are able to store "stormwater and gradually returning it to surface flow, reducing the effects of erosion by stabilizing soils, and dampening the effects of wave action". M. Dennison et.al. 1993. Wetlands also provide a feeding ground and habitat to many fish, waterfowl and other wildlife. Many endangered birds nest and breed on the shores of wetlands and these habitats are crucial for their survival. The destruction of wetlands has become a major problem, especially in California.

Although the amount of pollutants from a single town or construction site may seem insignificant, the combined concentrations of contaminants threaten our lakes, streams and wetlands. When things such as: human and animal waste, decaying plants and animals, discarded litter, or food waste enter surface waters, either dissolved or suspended in stormwater runoff, they can deplete the supply of dissolved oxygen in the water. When dissolved oxygen is reduced below a certain critical level, it can impair or kill aquatic plants and animals (CNYRPDB, 2011).

Back to the history, the eutrophication problem was first time concerned by public on Great lakes at the 1960s, the Lake Erie was covered by algae as a result of over dumped phosphorus from the sewage and other waste water, at that time, the Lake Erie was known as the “Dead Sea of North America”(Fitzpatrick, J. J., and Di Toro 1999). The reason cause this problem can be concluded in 2 points, 1. the stresses of overfishing, 2. development of phosphorus-based detergents. At the end of 1960, the Canada and the United States have realized the penetrance of this problem and finally sit on the table to sign an agreement that limiting phosphorus dumps to the Lake Erie, and plan to control existing unstoppable algal growth. Because of the awareness of Canada and US government, the concentration of phosphorus got a significant success. And this problem happened again during the 1990s, but this time the reason why this happen is more complexly.

Wetlands are very good at filtering out pollutants and things you do not want in your water. Without them, your water would be full of chemicals and other nutrients at high levels. This paper is intended to show how valuable wetlands are to the well-being of our environment and to the people of this county. It will reveal research methods and results. Finally, I will be making a recommendation on how to solve this problem based on the research that was done.

The Great Lakes, though fairly clean, are contaminated with some deadly chemicals that have slipped by human filtration into the lakes. These emerging chemicals have been determined to pose some health risk to humans and surrounding ecosystems and are used by society, but are unregulated or inadequately regulated retardants (Miller-Branovacki, Lindsay, "Water Resources and Urban Waste Water (Week #8)"). More specifically an emerging contaminant is one which is not historically widely distributed, nor a concern, however are now persistent and bioaccumulative making them a concern for the environment. The three major categories for emerging contaminants are; endocrine disrupting compounds (EDCs), Pharmaceutical and personal care

However, the Oxygen and pH levels are outside their healthy levels. As the level of dissolved oxygen in the water is lower then what is healthy, this can kill organisms that habituated the wetland. As well as the pH being higher than its healthy range, this can also kill organisms. The termination of these organisms can create devastating effects on the health of this environment by generating an imbalance in the ecosystem of the wetland. To ensure that the wetland remains an asset to the Canberra community, we must constantly observe the water quality in the wetland, and ensure that we are not polluting the wetland with air pollutants (NO2) and ensuring that the level of pH lowers from alkaline to be in the healthy range.

When oxygen and nitrogen combine in water, it forms nitrate, which is an essential chemical for eukaryotic algae; however, cyanobacteria do not need nitrate for their survival, contrary, they use elemental nitrogen. This way, even after the evolution of true algae, even though in fewer quantity, cyanobacteria remained widespread, and oxygen was accumulated.

Phycoremediation is the use of micro- or macroalgae for the removal or biotransformation of pollutants, including nutrients and toxic chemicals from wastewater (Olguin, 2003; Mulbry et al., 2008). It is a novel, low cost and an effective technique that uses simple and economical method as compared to the other conventional treatments on the basis of nutrient removal (Elumalai et al., 2013; De La Noue et al., 1992). Phycoremediation is comprised of several applications: (i) nutrient removal from municipal wastewater and effluents rich in organic matter;
