Transcript: Water = How to Make The Tap Water More Pure Difference Between Wastewater treatment & Septic Tanks Conserving water is important because it makes sure that there will be enough supply in the near future. Water conservation also helps save the environment, energy as well as the money used to supply water. Andreea Rebegea Water pollution in Albania is mainly caused by disposal of trash, and discharge of untreated wastewater and sewage. Lana and Tirana River are clean at their source, but once they enter Tirana, their water is several times more polluted than allowed standards. Wastewater: Water mixed with waste matter Septic Tanks: A tank, typically underground, in which sewage is collected and allowed to decompose through bacterial activity before draining by means of a soakaway. Recycle plastic and other materials STOP throwing trash in the sea Enjoy the sun & have fun! In many places, getting more use out of existing supplies isn't enough—more water is needed to meet the needs of a growing population. In those cases, desalination looks attractive. "Around here, however, we don't look backwards for very long. We , opening up new doors and doing new things, because we're curious... And curiosity keeps leading us down new paths." Walt Disney Don’t throw paint, oils or other forms of litter down the drain. Use environmentally household products. What Can We Do Stop Water Pollution? What Can People Do to Stop It? The First Sea Project Based On Water In Albania Don't overuse fertilisers. This will prevent material runoffs into nearby water sources. More Plants= cleaner water Don’t throw litter in water. Help clean up any litter you see on beaches or in rivers and lakes, and put it in a nearby trashcan. Recycling and re-use Install a water meter. Benefits of Wastewater Presents What should we do to clean up waters on the coast? Tapping Drinking Water Water Conservation Remove chlorine and heavy metals Use a heavy-duty carbon filter for removing hormones, drug residues, chemicals, pesticides, and herbicides Let the water stay in the sunlight and then add lime.

It is found naturally in rocks, plants, soil, and volcanic dust. The most common chromium is trivalent chromium. Chromium-3 is essential to human diet and it is found in vegetables, fruits, and meats. Chromium-6 on the other hand can cause lung cancer and damage the intestines. Sulfate In Drinking Water Private Wells 15% of Americans use private drinking water supplies. They are not set for EPA standards, though. People using private wells take special precautions to make sure their water is safe. Insures the quality of America's drinking water and EPA sets the standards. SDWA was originally passed by congress in 1974 to protect public health by regularly nation's public drinking water supply. Chemical Drinking Water Effect Chromium In Drinking Water News Article Bibliography Drinking Water Exposure Contaminants are most likely to cause chronic health effects such as cancer, liver and kidney damage, disorders of nervous system, damage of immune system, and birth defects Definition Sulfate occurs naturally in drinking water. The health effect associated with sulfate is diarrhea. EPA shows that 3% of the world's public drinking supply may have an estimate of 250 mg/L or more.

Transcript: Our well water test determined that there is no E. coli or Coliform present in our water. The Ausable Bayfield Conservation Authority has had the aquifer sampled showing concentrations of nitrate, chloride and fluoride to be well below provincial water maximum standards and may or may not even be present. (Schnaithmann). According to Gary Reavie (2012) of Davidson Well Drilling, any activity above the aquifer has the potential to affect my drinking water. "Because water is used and reused, and because it is such a powerful solvent, it is easily polluted. Pure water does not exist in nature. Water is a solution containing many different dissolved ions." (Mustoe, 2001, pp. 357-358). "Human activities causing compaction and degradation of soil reduce natural water purification ex. heavy farm equipment, building of structures." (Landry). Accidents on roads and railways involving chemical spills (gas, oil) and road salt can potentially get into our water. At the Holmesville landfill, rainwater percolates through landfill waste and dissolves numerous compounds, many of them toxic. (Mustoe, 2001, p. 358). Many activities and events that society is involved in can contaminate the environment and potentially pollute the drinking water, creating a health hazard! My septic system turns our waste water from the house into a cleaner solution that can be evenly distributed under the ground and mixed with ground water, without a risk of health problems. Waste water from the house enters the septic tank through a pipe. The septic tank has two sections. In the first section, the solids decompose and soaps and enzymes remain there. A wall separates the two sections, allowing only liquid into the second one. This liquid gets stirred up and is pushed out through a pipe to the tile bed by water displacement. This grey water moves through the tile bed via pipes with holes that let the water drip out into the tile stone, which is 60 centimetres deep. The tile stone and top soil filter the water. 60%-70% of the water going through the tile bed gets evaporated and purified. The ground filters the water more as it moves downward separating out the impurities. Eventually it reaches the aquifer. Each stage filters the water more. (McCullough). A septic system should be inspected annually and pumped regularly. With three people living in our home, our septic tank should be pumped every four years. Maintenance only plant grass near the septic system, roots could cause damage no driving on or heavy equipment don't build over the drainfield conserve water do not dispose of anything harmful through the system divert other sources of water (ex. roof drain) (Maintaining, 2004) Society could potentially contaminate my drinking water in many ways! "Air, water and soil can become polluted from vehicle emissions and factory smoke stacks. Acidic gasses produced, dissolve and contribute to the formation of acid rain. The concentrations of ions in ground water are affected by how acidic the water is. Acidic water increases the leaching of aluminum ions in the soil into rivers and lakes." (Mustoe, 2001, p. 358). Acidic gasses are solutes, which dissolve into rain water, which is a solvent. In the summer, Harvey Dale (2012), of H. T. Dale Septic Tank Service, spreads the material from septic tanks on his field. In the winter, he takes it to the sewage treatment plant, in the area that is capable of excepting the material. The material is not treated at all before disposal. Most things should NOT go down the drain! Some of these include, food scraps, grease, coffee grinds, cooking oil, kleenex, paper towels, cigarette butts, dental floss, chemicals, paint and antibacterial soaps. If something doesn't break down naturally, don't put it into the septic system. (Maintaining, 2004) My Septic System "My Drinking Water" I live on the Bayfield River. Phil Landry (2012) of the Huron County Health Unit states that, activities causing pollutants to enter the river could contaminate the aquifer our well draws water from. He said that contaminants can reach our drinking water through the ground. "Septic tank leakage, sewage treatment plant spills and leaking underground oil or gas tanks are possible contaminants", says Bill Rathwell (2012) of Rathwell & Rathwell Petroleum Handling Systems. Use of chemicals, such as weed spray or fertilizer, on lawns and golf courses are a threat to our water. Farming activities on and around our farm: Spreading chemical fertilizer (nitrates, phosphates) Spreading pesticides Spreading manure They could all potentially pollute surface water and may get into the ground water and aquifer by runoff or directly through the ground. (Schnaithmann). Man-made drainage systems increase the risk of contamination because of the concentration of water in a small area. This water gets into creeks and rivers more rapidly. "Septic systems and the ground filter out bacteria but not chemicals, such as gas and oil." (Landry). According to Steve

Without the ownership of land, one is not guaranteed the access to a clean water source. In order to rectify the social injustice of clean water, more people must be aware of the clean water scarcity crisis around the world. People must force government leaders to get involved and make new laws to revise current clean water acts. The nation must cooperate to help the world clean and conserve water sources to improve living standards and health around the world. Organizations like UNICEF, WaterAid, and World Health Organization have been working to reach their millennium development of reversing poverty, combat disease, increase education, ensure environmental stability and cut the amount of people without the access to clean water in half. In most developed nations, many people take access to safe water for granted. Many people may not know that in today's world, about one out of nine people are without an access to clean water. About a century ago, London, Paris, and New York were becoming centers of infectious disease. Reforms in water and sanitation took place soon after, enabling human progress to take over. More than 3.4 million people in the world die each year from sanitation, water, and hygiene related causes. Every twenty seconds, a child dies from a water related cause In Africa alone, 345 million people are without water accesses. Over 90% of diarrheal diseases in the world today are caused by dirty drinking water and affect children under 5 years of age. Drinking Water Poverty http: //vimeo.com/27574707 It is important that the quality of water is protected so that it can protect the lives of people worldwide, which leads back to the Catholic Principles of Social Justices: Life and Dignity of the Human Person, Option for the Poor and Vulnerable, and Care for God’s Creation. We must try to improve the quality of life for all those who cannot afford to live the life that many take for granted.
Transcript: Investments should be made to the following: Wastewater Treatment and Septic Tanks Water Conservation Water Purification Wastewater treatment can be used to clean the wastewater taken to the rivers that ends up in the sea. It would help lower the water pollution and it can also be used as drinking water (if filtered good), for agricultural purposes or industrial ones.

Solutions Steps to purifying water I think the state should start cleaning and reusing wastewater. Works Cited Nonpoint water pollution sources are runoffs, sewage draining on bodies of water, exposed water getting contaminated, and pollution from industries. Point water pollution sources are sewage and the garbage thrown into rivers and other bodies of water. Tap water is usually filtered by the government before distributing it to houses. To make it more pure in house conditions someone could boil it. Water conservation methods I think there should be more effort put into helping stop water pollution Water Pollution No Future Water Shortages Water Management Issues Drinking Water People would want to invest on water conservation because it helps prevent the water pollution on nearby lakes and rivers due to leaking and detergents. There are several ways to conserve water: Where they would be used There should be better sewage systems. Not allowing the water in artificial lakes get contaminated. Making people aware of the consequences of the garbage being thrown on bodies of water. Septic tanks are tanks in which sewage is collected and left for the bacteria to decompose. Later on, the clean water can me used for farming purposes. Here are some ways to purify water: Boiling it Using chemicals like iodine Filtering it through sand or soil Distillation Wastewater treatment is the cleaning of wastewater which includes water from runoffs, industries, and home usage. Checking if faucets or pipes leak Shorter showers Use the dish washer less When washing dishes by hand do not let the water running Wastewater treatment vs. Septic tanks Wastewater Treatment and Septic Tanks Better management of the natural water sources Water Conservation Water Purification
