waste water discharges by the industries cause serious pollution. Besides‚ non point sources along with the stretch of the river are also important sources of pollution of these rivers. (IWM‚ 2004) The river Turag running by the side of the Dhaka city‚ the capital of Bangladesh‚ is one of the most polluted rivers in Bangladesh. Many industries have set up in and around the Dhaka city during the last decade‚ and the number of the new industries are continually increasing. The water quality of Turag

Fracking is currently regulated by the EPA under the clean water act of 2005 (EPA.gov). However‚ this only partially governs the methods of injecting fluids and the retrieval of such fluids into the earth. It does not govern the types of chemicals that are being allowed to be used‚ or how much fresh water is wasted (millions of gallons per “Frack job”) and it does not carry stiff enough penalties for spills or irreversible damage to community’s water supplies. For those of you‚ who are unfamiliar with

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

experiment‚ the question being asked was: “What is the water quality of the U-High stream based on the water invertebrates found?” The purpose of this experiment was to determine the water quality of the U-High creek. The data was obtained by collecting soil‚ algae‚ and water from the U-High creek and identifying the number and types of invertebrates that were found from the samples. The prediction made was that the U-High creek’s water quality was poor based on the first observations of beer cans

Introduction Paragraph The question that’s being investigated is what is the water quality of the U-high creek based on the macroinvertebrates found in the creek. Water quality can be measured in various ways including oxygen levels‚ pH‚ nitrogen and phosphorus levels. Dissolved oxygen is when oxygen molecules mix with water molecules. It is important because water gets into oxygen from the surrounding air.The pH scale is used to measure the relative acidity of solutions and phosphorus is a chemical

The question being looked into is “What is the water quality of the U-High creek‚ based on invertebrates found in the U-High Creek? “Dissolved oxygen is oxygen mixed with water. The range to measure how much dissolved oxygen is in a solution is 1-14 milligrams per liter. This is important because fish and other organisms in the ocean breathe off of dissolved oxygen. Phosphorus is used to measure the relative acidity of solutions such as water. The range for pH is measured in 0-14 scale. 0-6 is unhealthy

What patterns do you observe based on the information in Table 1? As dissolved oxygen is increasing the number of fish are being observed more. When dissolved oxygen is at 12‚ the number of fish observed peaked at 15 and then falls. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and
