Are there high bacteria levels in our local recreational waters?
People in the Piedmont of North Carolina often swim and play in the recreational waters in the area. These waters all have public access and are surrounded by wild life. As our communities grow, there are more factors that cause water quality issues for the lakes and rivers that we use for play. Unsafe levels of bacteria in our recreational waters can create conditions that may lead to mild sicknesses or even deadly diseases. Some of the common recreational water illnesses(RWIs) created by the bacteria found in our waters include infections of the eyes, ears, skin, lungs, wounds and diarrhea. More serious illnesses such as typhoid, cholera and enteric fever can also be caused by bacteria in recreational waters. Regular testing of these waters help us to prevent outbreak of these illnesses. I chose Belews Lake, High Rock Lake, Salem Lake and the Yadkin River for testing in my project. I expected to find that all of these waters would be found to be at safe bacteria levels.
I researched information about bacteria levels in recreational waters all over the U.S. to see how they vary and so I would know what to expect with my bacteria levels in my test results. In order to better understand this subject, I also read articles from governmental agencies and environmental organizations about bacteria levels and testing of local recreational waters. E. coli is a common bacteria found and is caused by the presence of fecal matter in the water. I developed a questionnaire to be used to interview Mr. Corey Basinger, with the NC Department of Environmental and Natural Resources and an authority on our local waters. I learned a great deal from Mr. Basinger about our local waters and how they test them. The NC Department of Environmental and Natural Resources tests our local recreational waters once a month unless there have been extreme differences in the bacteria levels. According to Mr. Basinger, wild life and livestock tends to be a major factor causing increases and decreases in bacteria the local waters. Wildlife using the bathroom in the water, discharges from waste water treatment plants, storm water, meat and any other food are causes of bacteria in the local waters. Natural disasters such as Super Storm Sandy can also cause bacteria levels to rise with increased runoff and failure and overflow of water treatment systems. Some local waters have been closed to the public previously due to unleveled bacteria levels. High bacteria levels can be a concern because it can effect human health, aquatic life health and other parts of our environment. Even though temperature does not cause change in bacteria levels, animals and humans are more active and in and around the waters when it is warm. Mr. Basinger said that the bacteria levels at High Rock lake were usually higher due to the wildlife and livestock in the area.
The average low for bacteria levels are 200 CFUs(colony forming units) and 475 CFUs as a maximum in our local waters. According to the U.S. Environmental Protection Agency, the maximum allowable level of E. coli moderate swimming areas is 298 CFU. The waters I tested are considered as class C, which has Swamp Waters, Trout Waters, High Quality Waters, Outstanding Resource Waters and Nutrient Sensitive Waters. It is acceptable to build anything close to or next to a class C body of water. This can create possible hazards close by our recreational waters.
For the purpose of testing the water, I chose to use both the Easygel Total Scan test and the Easygel Coliscan test. The Total Scan test measures all forms of bacteria present in the water. The Coliscan test measures E. coli bacteria. These tests included sanitary pipettes for water collection and measurement, Easygel treated petri dishes, sterilized test tubes and the Easygel testing liquids for each test.
Ionic and Metallic Bonds Ions • When a metal and a nonmetal bond, they do not share electrons. Instead one or more valence electrons transfers fro the metal atom to the nonmetal atom. • After electrons transfer the atoms bond and form a chemically stable compound. • When an atom loses or gains a valence electron it becomes an ion. • An ion is an atom that is no longer electrically neutral because it has lost or gained valence electrons. • An atom that loses valence electrons becomes an ion with…
Rapp Falmouth High School 2012-2013 Research Plan A. Problem Being Addressed: I have found that air pollution is increasing and many people are frustrated about the gas prices. My project on Solar Energy will solve that problem. I have been interested in doing a science fair project on solar energy to solve something. During the past week I learned that the gas prices have increased immensely in California up to $5.00(says http://www.californiagasprices.com/)! I also figured out…
Sufi Annoor, Long Nguyen Dear, Nucleus We Chloroplast heard that you were firing someone and we have a couple of reasons why you should not fire us! If you fire us it would be like killing yourself, I do things that other organelles can’t do but wish they could. Extremely important we are your food source; given you are plant cells. The first and most important reason why you cannot fire us is because we are on basically on bottom of the food chain we make energy for the plants to survive. If…

Art: Olmec white ware "hollow baby" figurine The most recognized aspect of the Olmec civilization are the enormous helmeted heads. Once theorized to be ballplayers, it is now generally accepted that these heads are portraits of rulers, perhaps dressed as ballplayers. The heads were carved from single blocks or boulders of volcanic basalt, found in the Tuxtlas Mountains…

Hakeem Stamper 12/17/11 Ms.Milkosky Biology cp 1. Introduction- This lab that me class recently did was about glucose and starch and if they are permeable or impermeable to certain liquids. This lab showed us what liquids can pass through a glucose cell or a starch cell and which ones cannot. We had to make the cells out of dialysis tubing and left them in sit in a cup of water. After one day of experimenting we look and observe to see what has happened. We then use a glucose test strip too…
How do different liquids and solids affect the boiling and freezing point of water? Name 02/12/12 ABSTRACT There are many different substances that affect the freezing and boiling points of water. This experiment was designed to test the effects of five liquid and five solid substances/mixtures on the freezing and boiling points of water. It was hypothesized that if we tested five liquid and five solid substances/mixtures then the results would show that the solids would have a greater affect…
A healthy environment is heavily dependent on the actions that a community takes in order to keep it in a stable state, which will ultimately affect the well being and health of the humans themselves. Humans play a significant role in the quality of the environment and atmosphere based on the actions they take each day. Depending on the actions they take, the environment and atmosphere can be affected both positively or negatively. The health of the environment and the health of living orga…
QUESTION The Birthday Paradox states that within a group of 23 randomly selected people there is a 50% chance that two of them will have the same birthday. If the same equation is used but the amount of people is doubled, will there be more than one pair of people with equal birthdays? HYPOTHESIS If the Birthday Paradox is tested with twice the people than in its original formula, the results will be true and there will be more than one date where two or more people share the same birthday.…
