Lab Report On Water Pollution Lab

2. What are examples of bacteria and pathogen of concern in water that can cause illness?

Due to the large bodies of water in the county, there is a high risk for drowning. Water quality pollutants in the county come from fertilizers, bacteria from animal feces, sediment from land that are being cleared and stream channel erosion. When the rain falls into farms, parking lots, construction sites, and lawns the water collects pollutants and they get carried to the stream and then eventually end up in the Chesapeake Bay. In 2010 10 out of 15 streams sampled were rated far to poor, E-Coli, dissolved oxygen, fecal coliform, Chlorophyll-A and Polychlorinated Biphenyls were noted in the samples (2013 Natural Resource Indicator Report, 2014). C & R Battery Company Inc. and the Defense General Supply Center DLA were found on the national priority list for the most hazardous waste sites identified by the Environment Protection Agency because it is a risk to human and/or the environment (Virginia Superfund Sites, 2013).

Please briefly describe the different types of water pollution mentioned throughout the "Poisoned Waters" video. Fertilizers, Nitrogen and Phosphorous caused algae which poisoned the waters. It caused a dead zone. The farmers who own chickens was allowing the manure to pollute the water. The humans race is all responsible as we pollute our water by throwing garbage into it. Soap, household cleaning agents, toothpaste, and other plastic, lubricant and fuels are all poisoning our water.

Today in medicine doctors are rapidly isolating and distinguishing the many pathogenic microbes encountered daily within the environment. Public health has been affected from the faster identification of microorganisms by delivering an accurate analysis to patients in order to receive treatment of the disease in a timely manner. Due to the growing understanding of these organisms more have been easier to indicate to improve water quality. Also more methods have been developed for better treatment options from fecal bacteria in public water systems. Scientist has developed such specific methods of identifying the unknown organism to tell if the contamination has come from either a human, bird, or mammal. (Achtman et al., 2008)

We did 3 different test to help conclude the water quality. The first testing/station i did was to see what kind of critters were living in the water. Then, my next group was to take a test to see if eutrophication was in the water. We also took

The water supply was officially switched in April of 2014, and shortly after, residents began to complain about the smell and color of their water. Months after resident’s complaints were essentially ignored, E. coli and coliform bacteria were detected in the water (NPR, 2016). Residents were advised to boil their water until pipes were flushed and water was treated with chlorine. The exact same scenario occurred for a second time in September.

The first station we had was counting crustaceans and macroinvertebrates in the water. We found 113 critters that belonged in group 1 which means it is quality water. There were 2 organisms in group 2 which was somewhat quality water. Also, 16 critters in group 3 which means the water is very polluted. Overall, based on the critter

This paper will inform the reader why the Delaware River was polluted and how it is being solved. The Environmental Protection Agency (EPA) is trying to clean up all rivers and lakes to make sure that every waterway in America is healthy and not harmful to humans or animals. With the coordination of the EPA, and the Delaware County Regional Water Quality Control Authority (DELCORA) are trying to fix the problems that have occurred over years that humans have been around the Delaware River. The use of a Combined Sewer Overflow Program also known as a CSO is very important for the protection of drinking water in major cities including New York City and Philadelphia. The toxic chemical levels are at an all-time high making this one of the dirtiest rivers in North America. This paper will talk about what results were received from the multiple tests that were taken from multiple sites along the Delaware River and its tributaries. Also, what solutions are being used to solve the problem that is at hand to make sure the public has knowledge of the toxic levels in the water and to make sure that everyone including the animals nearby have clean and safe drinking water?

Several species and organisms rely on water to survive. Some organisms use it as a source to drink and others uses water as their living environment. This experiment is to calculate many aspects of the water that surrounds Corpus Christi. Water is the key to life on Earth and thus why water is so important. According to the Lab Report water quality is the quality of water and if it is considered acceptable drinking water. Water quality consist of its chemical, physical and biological characteristics. These properties can be studied through pH testing, nitrogen testing, Phosphorous testing and many other useful ways. Water quality is important because it allows scientist to identify if the water is in a good condition to drink or sustain life overall and it dramatically effects how healthy it is. The objective of this lab was to experiment if the water quality around the Corpus Christi is a reliable source of water for organisms and to reach an understanding of the water quality of the water surrounding Corpus Christi.

Contaminated water poses health risks on humans, pets, wild animals, and farm animals. (Mcdermott-Levy 2013)

The Great Lakes, though fairly clean, are contaminated with some deadly chemicals that have slipped by human filtration into the lakes. These emerging chemicals have been determined to pose some health risk to humans and surrounding ecosystems and are used by society, but are unregulated or inadequately regulated retardants (Miller-Branovacki, Lindsay, "Water Resources and Urban Waste Water (Week #8)"). More specifically an emerging contaminant is one which is not historically widely distributed, nor a concern, however are now persistent and bioaccumulative making them a concern for the environment. The three major categories for emerging contaminants are; endocrine disrupting compounds (EDCs), Pharmaceutical and personal care

The contamination was ultimately found to be Escherichia coli 0157:H7 commonly referred to as E. coli or EC0157. Investigations by the U.S. Environmental Protection Agency (EPA) and the Missouri state and county public health departments determined the most probable source of contamination was leakage of sewage near broken water main lines that then entered the drinking water distribution system (Swerdlow et al, 1992). According to the report by Swerdlow et al (1992), this particular incident had the distinction of being not only the largest incidence of EC0157 infection at that time but also “the first due to a multiple resistant organism, and the first documented to be transmitted by water” (Swerdlow et al, 1992, p. 818). Testing of water taken directly from the wells in Cabool revealed the water contamination did not occur in the ground water itself but was initiated in and then distributed via the water supply system.

One particular bloom in the summer of 2014 was of poisonous algae which produced the toxin microcystin – consumption of which can cause diarrhea, vomiting, and even liver failure – that had formed in an area of Lake Erie used for the city of Toledo’s drinking water (Wines, 2014). The city issued a notice to the approximate 500,000 citizens using that water informing them not to drink it, even after boiling. The ban took two days to lift, impacting the ability of those citizens to get fresh drinking water during that time.

The sample tube taken from the pond down by the turf field at USM was taken out of the incubator and observed. This sample was taken February 7th at around 2:30 in the afternoon. The results showed the entire 50ml sample mixed with COLISURE being completely purple, meaning it tested positive for Coliforms. What was different was the 44 wells with the pipetted samples in it. 8 of the wells remained yellow, meaning they were negative for Coliforms and the remaining 36 were all shades of purple meaning they were positive for Coliforms. The well plate along with the 50ml tube of the sample taken from the pond near the turf was then put under an ultra violet light, this helped us detect if the sample was positive for Escherichia coli. Under the ultra violet light, the entire tube sample as well as 3 wells in the well plate were glowing, meaning they were positive for Escherichia coli. In comparison to the other samples, this pond was by far the most dangerous for human consumption or swimming in. After this discovery, the most probable number (MPN) of both positive wells as well as wells positive for Escherichia coli were calculated. For the first sample from the pond near the turf field the MPN was calculated by first identifying the total volume dispensed into the wells. This was calculated was using the equation 0.2ml x 44 wells = 8.8ml. Next, the number of cells per

Although the state of America’s water infrastructure is of great concern, the types of chemicals found in America’s tap water are equally as frightening. The passage of the Water Act in 1972 prevents the direct dumping of hazardous chemicals directly into waterways, and helps regulate quality standards of water. However, the Clean Water Act is has no jurisdiction on regulating indirect dumping of chemicals that integrates into water supplies. Pesticides and prescription drugs are the greatest cause for concern of indirect containments in America’s water supply (Olsen). An abundance of the harmful chemicals found in liquefied animals feces, used in large dairy states, have percolated into drinking wells that have caused serious infections (Duhigg). However, more harmful containments are infiltrating water supplies. Such containments include
