Water that we drink doesn’t enter directly from the water source to our faucet. Many steps are taken to ensure that the water we drink and use is safe. The EPA has set up a standard by which the water must meet before entering the households throughout the country. Water quality can vary throughout the United States depending on the sources, available technology, and economic resources. In order to ensure that the water quality stays safe the EPA requires standard samples to be checked to ensure that the water is drinkable and safe. Coliform an indicator bacteria is just one of numerous amounts of bacteria that are checked in a standard check of water taken from water sources. One of the many standards that the EPA tries to maintain is less than one coliform per 100 ml of water. In order to obtain this goal the element of chlorine is added in order to kill off many of the harmful bacteria. Other tests are done in order to insure the high quality of our drinking water. Physical contaminants can be tested for by looking at odor, taste, color, turbidity, and total dissolved solids, referring to bicarbonates, sulfates, calcium, and other minerals and matter. The EPA’s standards allow us to determine the difference between healthy water and water that can be harmful towards humans, animals and the environment. Drinking standards that have been issued by the EPA give the â€Å"Maximum Contaminant Levels (MCLs) for more than 80 contaminants.† (Online) Available: epa.gov/safewater/wot/howsafe.html. These MCLs help ensure that our water quality is set to a level that allows us to protect public health. Most all of the 80 contaminants that are checked and managed are looked at in lifetime exposure in order to secure the future of American water safety. Currently, â€Å"the nations approximately 55,000 Community Water Systems (CWSs) must test for more than 80 contaminants. In 1996, 4,151 systems, or 7 percent, report...

Free Essays on Water Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5.6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of sulfuric acid, some of its uses and the effects of it as a pollutant in our environment. Sulfuric Acid Industry in Ontario Among the many plants in Ontario where sulfuric acid is produced, there are three major plant locations that should be noted on account of their greater size. These are: Inco. - Sudbury Noranda Mines Ltd. - Welland Sulfide - Ontario There are a number of factors which govern the location of each manufacturing plant. Some of these factors that have to be considered when deciding the location of a Sulfuric Acid plant a re: a. Whether there is ready access to raw materials; b. Whether the location is close to major transportation routes; c. Whether there is a suitable work force in the area for plant construction and operation; d. Whether there is sufficient energy resources readily available; e. Whether or not the chemical plant can carry out its operation without any unacceptable damage to the environment. Listed above are the basic deciding factors that govern the location of a plant. The following will explain in greater detail why these factors should be considered. 1) Raw Materials The plant needs to be close to the raw materials that are involved in the production of sulfuric acid such as sulfur, lead, copper, zinc sulfides, etc.. 2) Transportation A manufacturer must consider proximity to transpor-tation routes and the location of both the source of raw materials and the market for the product. The raw materials have to be transported to the plant, and the final pro... Free Essays on Water My presentation is about a substance vital to everyone and almost everything. If you haven’t guessed by now, yes it is about water. It covers why water is needed for the human body to work, what happens without enough water, and how much water is used and wasted in the U.S. The first topic to be covered will be how your body uses water. Water is used in all of the major systems for a variety of uses. It used for digestion, controlling the temperature of the body, getting rid of the body’s waste, and transporting nutrients. Water makes up most of the body with studies showing the amount ranging form 72% up to as high as 83%. Most major organs are at least three-quarters to four-fifths water as well. It’s no wonder that water is often called the body’s most important nutrient. The body can survive up to a month without food but without water a person would die in a few days. Without water many things begin to happen. If body fluids drop 5% people suffer a 25-30% drop in energy while a 15% drop can result in death. Estimates to how many people suffer dehydration to some degree range at one-half to two-thirds. Most of these people then drink coffee or soda to boost their energy levels but these actually lower the body’s water content and reduce the body’s ability to produce energy. Also water cleans the digestive system and this makes it work better, this results in the body being able to work better as a whole. So drinking water is a good thing to do. Also if you drink beverages that have caffeine in them, drink them in moderation and remember to drink more water to compensate. Some sources recommend a minimum of 10-12 glasses of water a day, 14-16 is recommended for maximum benefits. Most studies don’t recommend this high of an amount though because it is possible to get water poisoning. About 85% of all Americans use roughly 34 billion gallons of water supplied by public water systems. The rem...
