When the water is so contaminated that you cannot drink it, what could you do to get a pure glass of H2O? Students taking Western Kentucky University (WKU) Dual-Credit “SPAN Chemistry” class at Metcalfe County High School (MCHS) completed a lab investigation of the distillation of contaminated water.
In this lab students tested the given contaminated (hard water) for the ions present in the water prior to the distillation, and then after the distillate (pure water) was collected, the same procedures were followed to prove the absence of the hard water contaminates. SPAN Chemistry is so called because this dual-credit class spans the gap between high school and the extremely rigorous college chemistry expectations.
If you have lived in Kentucky very long you know what “hard water” is and how it leaves a scale on our bathroom fixtures, clogs our hot water tanks, makes it hard for soaps to lather and clean our clothes, leaves

These ions along with chloride and sulfate ions are very common in our water supply and typically we simply learn to deal with hard water as a way of life in Kentucky. If you need or want to reduce the amount of these ions, especially calcium and magnesium, consider getting a water filter for your faucet tap or refrigerator.
For more information on hard water in Kentucky, see the following article on Hard Water – To Soften or Not to Soften, by the Cooperative Extension Service at the University of Kentucky, College of Agriculture. (http://www2.ca.uky.edu/agcomm/pubs/ip/ip7/ip7.pdf)
If you are a MCHS WKU student in chemistry, you get to investigate how to test for these dissolved ions and then physically separate the pure water from the dissolved minerals/ions and prove that distillation is an absolute way to obtain the purest form of H2O, albeit a more expensive and time consuming
“For many of us, clean water is so plentiful and readily available that we are rarely, if ever, pause to consider what life would be like without it,” said Marcus Samuelsson. According to the Des Moines Register, “The federal Environmental Protection Agency is adding $12.3 million to a loan fund that will help pay for drinking water systems or improve efficiency.” There are obvious water quality issues in Iowa, and people around the state including farmers and the governor are trying to help.
The data from the TDS analysis (table 2) show that tap water Mifflin hall, well water Wyckoff and stream water Raleigh has a higher amount of total dissolved solid compared to tap water Harleysville and Tap water Yosemite that have a low amount of total dissolved solid. From these observations, we can conclude that tap water Harleysville and tap water are softer than Yosemite tap water Mifflin Hall, well water Wyckoff and stream Water Raleigh.
There are two sources of drinking water, surface water and ground water and they are each managed, monitored and regulated differently even though the actual water systems are interrelated and integrated. The state of Missouri has historically had plenty of high-quality fresh water sources; in the northern half of the state most of the drinking water comes from surface water while the majority of the southern population gets water from underground aquifers (Missouri Department of Natural Resources, 2010). The Missouri River and its alluvium wells provide more than half of the state’s residents with drinking water as most of the urban centers in the state are located along its course. Water from wells located adjacent to the Missouri River
I live in Howard County, Missouri. More specifically Fayette, Missouri. We get our water from Thomas Hill PWSD out of Moberly, MO, which is about 30 miles from my home. The Thomas Hill District supplies water many towns north of Fayette, including Salisbury, Huntsville, Rennick, Clark, Higbee and up to the Boone County boarder. The source of Thomas Hills water supply of “drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and groundwater wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity”(thomashillpwsd.com).
The minerals contained in hard water have a wide impact on your life and home. Hard water affects almost any task requiring water. Fortunately, you can reduce water hardness by contacting our plumbers in Sugar Land and scheduling the installation of a water softener on your water supply line. Once installed, the softener will protect your pipes, appliances, and generally make your life easier.
Contribute our academic research paper to environmental groups so that we will be a leader in water purification.
To start off our purification process we electrically shocked the water (Picture 1).We thought of this because of the hunger games when they shocked the water to kill of the organisms in it. Next we filtered it with filter paper to get out the chunks. We happened to do this three times, just to make sure. After we filtered it we decided to boil it for about ten minutes (Pictures 2 and 3).
I am guilty of some of these negative effects on our water supply. On a typical day I usually do not think about how much water I am using and I take it for advantage. I am aware of how many people struggle to get clean water but I never see this take place around my community, causing me not think of it and take into consideration as much as I should. I have never had to deal with obtaining clean water. Clean water has always been provided for my family and I ever since I can recall. My family lives in Hickory which means that we get our water from Hickory City. I typically use a lot of water I take a 25 minute showers every other day. I drink about 1 water bottle a day, I wash the
Previous attempts have been made to fix this issue. The previous home owner had installed a new Kenmore water softener, in which the owners had to continue to add three 15lb bags of Morton salt to clear up the iron that was going through the system. This brand of water system costs up to 600 dollars and once every two weeks had to have new salt put in, which costs fifteen dollars a bag. This put the home owner spending 90 dollars a month on salt, which turned into 1,080 dollars in a year. Because Brownsville has such hard, salt filled water and was an electric unit, the Kenmore system broke after a year. This leads into discussion of one of a few options that home owners can have.
Testing and analyzing the quality of water can be used to determine if the water is safe or not to ingest. Some tests performed on water will help determine if the water is bacteriologically free, contains chemical contaminant such as nitrates, the acidity of the water itself, or to see the amount of chloride in water. Hydrology is the study of water. It has evolved as a science due to the need of understanding the complex water system and to help solve water problems (USGS). In this lab, a series of titration were conducted in order to see the amount of calcium present in different samples of water in the state of Florida. Measuring the amount of calcium in water determines how hard the water is. Hard
“Micro-filtration which filters out heavy metals and contaminants followed by reverse osmosis which filters everything remaining and lastly, UV sanitation which destroys microorganisms and bacteria.There is no chlorine, fluoride, metals, contaminants, or minerals in the water following the purification process. The water is 99.9% pure. The purified water is then infused with the perfect blend of pure alkaline electrolytes (for taste) like calcium, potassium, magnesium, and sodium bicarbonate) in trace amounts. Finally, our proprietary ionization process supercharges the water, removing bitter-tasting acidic ions, producing an
In Kansas, ground water is the only available source of water in larger amounts. Kansans uses ground water for 85% of their water
Contamination of drinking water originates in different ways depending on the source of the drinking water, the type of contamination, and the method of water supply delivery (i.e. type of plumbing). Groundwater, which may be used as a source of drinking water, often becomes contaminated from percolation of toxics through contaminated soil. Alternatively, contaminated runoff and direct discharges contaminate surface water, which may also be used as a drinking water source. Drinking water may become contaminated through the leaching of lead from plumbing systems. Finally, the intentional addition of substances to treat the water supply, such as chlorine, also represent a significant source of drinking water contamination in public water supply systems.
Accumulation of heavy metals (Cd, Cu, Hg, Pb, Zn, As, Fe and Ni) in water could lead to downstream distribution issues and corrosion of the system. The occurrence of corrosion could be a result of potential problems during the water treatment process and have as an impact an alteration in water quality (Postawa and Hayes, n.d.). Consequently, for the avoidance of any issues in the water distribution system and subsequent complaints by consumers referring to the taste and odour and appearance of water, the concentrations of metals in water should be investigated.
3.1.4.2 Deionized water unit: De-ionized water used in the study was obtained from MilliQ Water Purification System (Elix 3 UV Water Purification System, Millipore) was used for distilled water.
