POST LAB QUESTIONS Develop hypotheses on the ability of oil, vinegar, and laundry detergent to contaminate groundwater. Oil hypothesis = Oil will not contaminate or change the amount of water filter. Vinegar hypothesis = Vinegar will contaminate through the soil allowing the water to filer through. Laundry detergent hypothesis = Laundry detergent will contaminate the soil by allowing the water to pass through. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1?
SCI 207 NEW WEEK 2 LAB 2 WATER QUALITY AND CONTAMINATION http://www.homeworkproviders.com/shop/sci-207-new-week-2-lab-2-water-quality-and-contamination/ Lab 2 – Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell, Color, Etc.) Beaker Observations 1 To me this is just water, there is no smell. 2 As you pour the oil in the water the oil started to bubble at the top. When stirring the oil turned into smaller bubbles. It looks as if the oil has placed a thick line of film on the water 3 After pouring the vinegar in the water the only change I noticed was that the water seemed to be a shade darker when added it.
The pollution or ground water, surface water, and soil effect plants and animals that live in the habitats and also carries E. coli bacteria to areas that can effect humans. B. Pollution of water is a huge issue when it comes to environmental issues that deal with factory farming since water is essential to almost all life. 1. Runoff into streams contaminates the water with animal waste which contains antibiotics and artificial growth hormones that are given to the animals to increase their size and to sustain their health.
| LEARNING OUTCOME | 264 | 2.2, 3.1, 6.4 | What are the main points of the policies and procedures for hand washing?Expose forearms – Bare below the elbowSingle band ringNo bracelets or watchesNails clean and of reasonable lengthNo false nails or nail polishWash with soap and water to remove dirt and micro organisms, or apply alcohol rubWash hands when visibly soiled, contaminated with blood or bodily fluids, after using the toilet, before procedures and before eating. | | | 264 | 3.1, 4.3, 4.4 | What procedures and systems are relevant to the prevention and control of infection?Handwashing – signs for service users and vistors, technique displayed in bathrooms/toilet areasHandgel provided to staff and pumps at main entrance of building.Handwashing used regularly e.g. before interacting with a person, after procedures, before serving food, after using toilet, after blowing nose, whenever visibly soiled, after each shift.Personal protective equipment provided e.g. plastic aprons and gloves for personal care/cleaning activities. New apron/gloves worn between contact with each service user.Uniforms provided to staff – should be clean and well maintained, hair should be tied
After shredding was complete the pile of cabbage was placed into a stainless steel cook pot. 2. In order to attempt to get the most accurate results I used my fish tank ph test to identify the ph level of my tap water. The result was my tap water is about a 7.8 (slightly higher than the 7.0 that is considered neutral). 3.
Most of the legal regulations relating to infection Prevention and control come under the Health and Safety at Work Act; this act is about ensuring a safe work place for employers, Employees and members of the public by minimising accidents at work. The Management of Health and Safety at Work Regulations introduced the need for monitoring health and safety and risk assessment; including infection prevention and Control. The Food Safety Act was brought in to ensure safe practices for food to avoid contamination and spreading of infection and includes handling, storing and disposal of food. Legal regulations that come under HASAWA include The Control of Substances Hazardous to Health (COSHH), this is relevant as it is about the prevention and control of pathogens and managing the safe storage and use of hazardous substances. Reporting of Injury, Disease and Dangerous Occurrences Regulations (RIDDOR) is relevant as it requires that any infection or disease that is work Related be recorded and reported.
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
Pesticides can travel great distances through the environment even if that is not the intention. Whether the chemical is sprayed on crops or in gardens, the wind can blow the pesticide to other areas that may be pesticide sensitive. They can also flow into rivers or streams where they are carried to new locations or they can seep deep into the soil and affect the groundwater causing unexpected harm to those who drink the contaminated water. As part of a National Water Quality Surveillance Program both British Columbia and Ontario were found between 2003 and 2005 to have the largest number of pesticides found in aquatic ecosystems and sensitive surface waters. Samples were taken from approximately 140 sites and 15 watersheds of various sizes.
History of the Water pollution control Act The first major law in United States to address issues of water pollution was the Federal Water Pollution Control Act of 1948 (Pub. L. 845, 80th Congress). This law assumed doctrines of federal and state joint program development, limited federal implementation authority, and limited central financial assistance. These doctrines were extended in the central Water Pollution Control Act of 1956 and in the Water Quality Act of 1965 (Pub. L. 660, 84th Congress).
Pollution in seasonal wetlands Wetlands are considered habitats that help trap and reduce pollutants that come from all types of sources, such as oils from cars, chemicals from drainage runoff, sprinklers that have fertilizer runoff from nearby grass located around buildings, agriculture runoff, untreated sewage from pets and human waste, and in flow of domestic and industrial wastes. Other harmful chemicals that are human related are antibiotics from animal husbandry, pesticides that act as endocrine disrupters. (Ramsar 2008) These pollution sources all contribute to the negative health of wetlands all over California. Roseville wetlands are being inundated with water pollution from many of these human related sources around them. Wetlands can only handle so much of these pollutants, and with the major habitat loss that has completely changed the dynamics of these once seasonal wetlands, can only limit the ability for these wetlands to filter as much of the pollution as possible.
