WATER QUALITY IN RURAL INDIA The rural population of India comprises more than 700 million people residing in about 1.42 million habitations spread over 15 diverse ecological regions. It is true that providing drinking water to such a large population is an enormous challenge. Our country is also characterised by non-uniformity in level of awareness‚ socio-economic development‚ education‚ poverty‚ practices and rituals which add to the complexity of providing water. The health burden of poor

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

Water quality and contamination Student’s Name Institution 20th September 2014 Water quality and contamination Introduction This report focus on factors that affects the quality of water‚ agents of water contamination and how water impurities can be removed for water quality. There are two visible features of contaminated water; colour and smell. Contaminated water usually has unusual smell and coloured. Invisible factors affecting water quality are sources of water. For instance; tap water

HOW NORTH CAROLINA IS EFFECTED ECONOMICALLY BY WATER POLLUTION About 80% of the State’s surveyed freshwater rivers and streams have good water quality that fully supports aquatic life uses‚ 17% have fair water quality that partially supports aquatic life uses‚ and 3% have poor water quality that does not support aquatic life uses. Ten percent of the surveyed rivers do not fully support swimming. The major sources of impairment are agriculture (responsible for 53% of the impaired river

The purpose of the study was to determine the quality of the Ottawa River and identifying any human activities that may affect water quality by sampling for benthic invertebrates‚ measuring the water temperature‚ testing for pH‚ turbidity‚ dissolved oxygen‚ examining the odour‚ colour‚ and appearance of the water‚ the amount of grasses‚ shrubs‚ trees‚ and known uses of the waterway. Description: Various human activities that may affect water quality include municipal wastewater‚ urban stormwater

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

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
