The Effect Of Water Quality On Faecal Contamination

The health of the Susquehanna River and Chesapeake Bay was found based on Biological (macroinvertebrates and wildlife) and Chemicals characteristics (pH, dissolved oxygen, phosphates, nitrates, etc.) as well as physical observations (amount of forested buffers, wetlands, etc.) Overall it was concluded that the health of the water was good to excellent. What was found was that many of the macroinvertebrates found in the water were sensitive or facultative, meaning the water quality was good enough for them to live in. Also, the level of ph, temperature, dissolved oxygen, phosphates, nitrates, and turbidity showed that the water quality was good. Finally, while we were canoeing down the Susquehanna River, observations were made on the land

Overall the objective of this lab exercise was to introduce students to watershed ecology and the ecological factors that affect water quality. Students used biotic (macroinvertebrates ) and abiotic indicators to asses the quality of water in a freshwater body. Specifically students collected water chemistry data (hardness, nitrate/phosphate concentrations, dissolved O2 and pH) to asses the quality of water. Additionally macroinvertebrates from the benthic environment of a respective field site were collected, analyzed as well as catalogued. Collectively the results indicated that a greater species diversity was indicative of greater water quality(Lenat). Likewise within a freshwater ecosystems a negative correlation was found to exist between fluctuating abiotic factors,species diversity and water quality. It can be concluded that amongst the three field sites the ranking of water quality from highest to lowest is as follows; Great Brook Farm, Russell Mill pond, Lawrence Street Stream.

Today in medicine doctors are rapidly isolating and distinguishing the many pathogenic microbes encountered daily within the environment. Public health has been affected from the faster identification of microorganisms by delivering an accurate analysis to patients in order to receive treatment of the disease in a timely manner. Due to the growing understanding of these organisms more have been easier to indicate to improve water quality. Also more methods have been developed for better treatment options from fecal bacteria in public water systems. Scientist has developed such specific methods of identifying the unknown organism to tell if the contamination has come from either a human, bird, or mammal. (Achtman et al., 2008)

A discharge of leachate and other pollutants could potentially affect the groundwater quality of the entire area (Ginns & Wright, 2014). Algal bloom outbreaks have also affected the water quality. Periodic water quality management of all waterways within the catchment should be continued to monitor sediment and leachate values. Encourage further bush regeneration to limit run-off linked to an increase in algal blooms. It is also worth noting that a large propeller is already in place to oxygenate the

The Alliance’s report gives a comprehensive action plan for reducing the amount of pollution in and river and improving overall water

Codi noticed an irregularity in the river when her biology students and herself tested the pH of the river and found that it was very acidic. The Environmental

We have performed three test to investigate the concentration of metal, pH of water, water temperature and the level of dissolved oxygen in the river. It helps us to discover the reason of the event and find out solution.

The environmental issue of interest is clean drinking water and the abuse of our water sources. The interest in this discipline is because clean water and water abuse have been an issue for many years. Many countries around the world and in our own back yard lack clean drinking water. The cause of unclean water can be caused by bad agriculture practices and industrialization. The cause of these unhealthy practices may cause waters to be contaminated with a mineral called Chromium; this mineral exposes a high risk of cancer. The county of Gwinnett is full of lakes, rivers, streams, creeks and ponds but the only source of drinking water that is disposed to residents comes from a man-made lake called Lake Lanier. The lake provides clean drinking

In the North Queensland Resource Planning and Development, the consumption of high quality drinking water has become a major issue. Due to the limited supply of fresh water in other states and South East Queensland, a major re-education of the public on water usage has occurred. The demand for water has increased within the Cairns region, so to provide the extra water needed for the Far North community, the government is considering tapping into the Mulgrave Aquifer. On further investigation, it was seen that this process would be quite expensive to go ahead with. A more viable option would be to source the water directly from the Mulgrave River. The purpose of this report is to analyse and discuss the water quality of four locations along the Mulgrave River.

The Upper Wabash River faces a vast majority of issues that affect the quality of the watershed. The watershed has long been used for agricultural purposes that cause stress on the watershed. Through various point source and non-point source pollution various water systems have been affected with some being even impaired.

When the Freshman Biology classes originally tested the water quality of the UHS creek, it was found to be excellent. However, not all creeks have excellent water quality. Humans can impact water quality when fertilizers and pesticides that are sprayed on plants wash into the rivers and creeks. The extra chemicals will bring down the quality in the water. Certain factories use river water to cool down or power their machines. The dirty or used water is put back into the river. If the water has any chemicals or dirt in it then it will cause the water quality to decrease. A lot of people hurt the water without realizing. What are some natural solutions to fix the damage done to the water? (http://www.lenntech.com/rivers-pollution-quality.htm)

The Androscoggin River is located in both Maine as well as New Hampshire and is used by so many living in these areas but also by tourists. The river was in jeopardy when it was made public about the amount of pollution in the water. An investigation was done in order to see the progress of the river’s water quality. The purpose was to check the water quality of the Androscoggin River by looking at the species living in the river as it was once very polluted due to human activity, such as a mill in Berlin, NH. The Upper Androscoggin River Fishery Management Plan was published in order to give those interested in maintaining a healthy river, the history of how polluted it has gone, and ways to understand that. The river runs through Bethel which

Few resources are essential to human survival. Access to clean water is the most critical of all. Water is a vital resource responsible for sustaining all life on earth. However, clean water is in short supply, but in high demand in all parts of the world. It is thought that most Americans have access to safe, affordable, clean water right from their taps. However, the media is uncovering the true nature of America’s deteriorating water situation. Americans have reason to be seriously concerned about the state of their drinking water. So what really is on tap in America?

According to Government of Malawi (2010), many river basins are under severe pressure resulting from deforestation, settlements, climate change, industry, mining, commerce and unsustainable agriculture. These have consequently impacted negatively on the water quality mainly due to sediment loads, industrial wastes, chemicals from agriculture and proliferation of aquatic vegetation.

Rivers are the blessing on earth as they serve humans with ample fresh water supply. The purpose of the present study focuses on the combination of the GIS mapping, to indicate the status of pollution status in the sketch of River Mouri, downstream to the wastewater outfalls. The GIS mapping of the eleven wastewater study parameters reveals that the high concentrations of BOD5, COD, DO, Color, Turbidity, TDS and TSS exceeding the permissible limits is present throughout the study portion of the river. In addition, it highlighted the portions where only few parameters such as PH, Chloride, Nitrate and Sulphate are deteriorating the riverine ecosystem. The GIS application in pollutant load assessment of the study further indicates that although few pollutants, discharged into river are relatively low in concentrations at one wastewater outfall point as compared to other but may have high pollutant load that may leads to significantly higher ecological impacts. The possible application of this study is for the decision makers to introduce optimum treatment engineering controls at points of interests, prior to its disposal into River Mouri to prevent the ecological damages and protect human health.
