Then by filtering, iodide can be extracted which when combined with other substances can make an iodine tincture, that is a pharmaceutical product. * Can a single substance be isolated from a mixture? Yes a single substance can be isolated from the seaweed mixture by using methods such as filtration and evaporation. In our experiment we used filtration using a filter paper funnel to extract the iodide from the tincture. * What is this substance This substance is iodide Confidence Report The aim of extraction, is to separate a part of raw material, using a solvent such as water with heat.
Using at least 1 scholarly source, discuss what type of affects these contaminants (oil, vinegar, detergent) might have on a town’s water source and the people who drank the water? Answer = "When water chokes you, what are you to drink to wash it down?" Aristotle, Nicomachean Ethics, 384-322 B.C.” According to Wisconsin Natural Resource, “Everyday activities can affect groundwater quality. Think about the ways you
In order to break this link, various methods can be used, including the pasteurization of milk, the chlorination of drinking water, or the use of disinfectants. 2. The Reservoir. This is the natural environment that the pathogen requires for survival. Reservoirs can be a person, an animal, or an environmental component, such as soil or water.
Identify the processes (e.g., coagulation) that were used in this lab and describe how they were performed. You start out with the contaminated water that has not been filtered out or has not had any chemicals added to it, this is many done so air can meet the water and this gives the chemicals and gases to release. I then added Alum to the dirty water since when mixing Alum with the dirty water it allows all the big particles to “stick” to the Alum and then pushes all of these particles to the bottom of the water. The dirty water is then put through a filter of sand, charcoal, and gravel in order for any of the smaller particles to stick to them and makes the water clean and free of any other particle. After I did all this I then had to add a few drops of bleach so I could disinfect the water from any other dirt
ABSTRACT Three experiments were completed to determine the quality of water that had been contaminated, soiled, and to determine the differences between the water that comes from a kitchen sink and the elegantly bottled water that is conveniently sold in the store. Using various Earth materials (sand, rock, soil, and charcoal) combined with scientific materials (beakers, funnel, and alum), the first two experiments tested the effect of contaminated waters filtered through a simple soil filter, as well as a complex Earth model filter. The final experiment used various test strips to test certain potential differences between tap water and bottled water. Testing Man’s Naiveté of Our Water Quality Drinking water in the United States has undergone many quality standard transformations throughout the 1900’s up until present day. There are many rules to follow when building structures, removing waste, and even when it comes to farming in all its forms.
Once an item has been cleaned it must be dried thoroughly with a disposable cloth to prevent any organisms multiplying. 2.3 Disinfecting agents are used to reduce the number of microorganisms. Disinfectants are governed by COSHH regulations 1999. Storage and usage instructions should be adhered to. The correct PPE should also be used when disinfecting items ensure that the solution reaches all surfaces of the item to ensure thorough disinfection before the sterilisation process can
Some of the environmental issues related to hydraulic fracturing must be investigated and regulations must be put in place. As a nation dependent on energy we must regulate and consider all consequences before allowing the depletion of yet another natural and non-renewable resource. Environmentalists claim an array of issues related to fracking. Polluted groundwater and aquifers, micro seismic events, disposal of waste water and the mining of the silica sand which is used in the process are all by-products of a loosely regulated practice. Studies have been done, from measuring the effects on drinking water to monitoring seismic events related to fracking.
These do not flow out of the fractured target zones. Instead, they are left to keep the fractures open. Acidizing of the fluid also may have been done during preparation of the fluid. This is done by addition of hydrochloric acid and helps in cleaning the pores for the fluid to flow out well and the gas that will
Chemical Mixing * Potential for indirect chemical release into water supply through surface spills or leaks 3. Well Injection * Potential for more direct contamination of water supply by surface spills or leaks 4. Flowback and Produced Water (Wastewaters) * Again, potential for direct contamination of water supply by surface spills or leaks 5. Wastewater Treatment and Waste Disposal * Inadequate treatment of wastewater could allow contaminants to reach drinking water and surface water * Byproducts formed by reaction of hydraulic fracturing contaminants with disinfectants It should be noted that a majority of these potentialities fall under the category of “human error”. It should also be noted that a majority of ANY potential failure in a system falls under that same category.
It is common to consider pollution to streams as being transported from industries and cities which release waste water into water courses such as lakes, rivers and streams through designated and established point sources. A bigger problem, however, actually comes from other unidentified sources where possibility of these contaminants being absorbed into the soil or transformed through natural processes before reaching the waterways is hindered by large impervious areas around the water body and short peak runoff times.
