experiment we tested the effect turbidity would have on the process of photosynthesis, if any and how it would change the carbon dioxide intake. By making turbidity a factor in the photosynthesis process we figured that it could possibly affect the way photosynthesis is produced in plants. In order for photosynthesis to be as efficient as possible for plants, it needs to be able to get a decent amount of sun light in order for the plant to be healthy, and turbidity makes water murky which could have
PREFACE The Chesapeake Bay is a large bay that stretches from Maryland to Virginia, fed by many rivers and streams that run from as far north as New York to Virginia and West Virginia.5 It is home to a plethora of plants and fish species, many of which the people of the area fish for food and supplies. The pollution present in the Chesapeake Bay is affecting the livelihood of both the fishermen and the fish – the less the fishermen haul due to the death of the species they catch, the less they get
Introduction What is your topic/issue within that topic? Eutrophication is a concern in the Chesapeake Bay. Eutrophication is caused by excessive amounts of nutrients. Excessive nutrients in the bay have negative effects on the bay's ecosystem. The extra nutrients make the environment unbalanced. The extra nutrients cause a chain reaction that eventually kills most of the organisms in that area. This is what is known as a dead zone. What is your personal interest in the topic? This topic is interesting
Water quality testing and monitoring is important for our environment. Water quality parameters such as pH, turbidity, conductivity and phosphate levels are important measures that can affect the quality of water in our environment. The pH measure how acidic or basic the river water is on a scale of 0-14 (Behar, 1997). According to the Environmental Protection
and Turbidity were measured and tested against SANS 241: 2015 (Umgeni Waters, 2017). Due to lack of equipment the turbidity Cl2 and pH could not be tested on site,
Turbidity method In microbiology there are many times when there is need to either estimate or to determine the number of cells in a broth culture or liquid medium. This estimation can be done by various direct and indirect methods. These include turbidity method, visual comparison of turbidity with known standard, standard plate count, direct microscopic count, measurement of cellular activity, cell mass determination. In our experiment to study the growth kinetics of E.coli we used turbidity method
Climate Change can be defined as the change in the pattern of the weather, related changes in oceans, land surfaces and ice sheets, occurring over time. ("1. What Is Climate Change? | Australian Academy Of Science") Climate change more in depth is the change in the statistical description of the state of the climate system that persists for usually 30 years. The climate is currently changing mostly due to increased human activities like burning fossil fuels of coal, oil or natural gas, agriculture
there are several mainstream parameters that are used in conjunction with each other to determine the water s quality. These include: alkalinity, ammonia content, carbon dioxide, chlorine, nitrates, dissolved oxygen, phosphates, temperature, and turbidity. The most visible sign of poor water quality is reduced animal populations. Almost all animals will suffer if pollutants are in the water supply. There are several ways to lower pollution levels in water. Alkalinity is not a measure of pollution
removal of the particles from the water; thereby achieving the removal of the turbidity from the treated water. In addition to the removal of turbidity, coagulation and flocculation also removes numerous microorganisms suspended in the water as well as phosphates from the water. For safety, the highest level of turbidity that is allowable in water is 0.5 NTU, and the recommended level is 0.1 NTU. (NTU: Nephelometric Turbidity Units) Colloidal particles: These small particles are primarily negatively
biodiverse areas that are especially unique to Australia and maintaining their health is vital for not only tourism, but also the survival of specific species and coral. As mentioned above; pH, dissolved oxygen, electrical conductivity, phosphate and turbidity are the main sources of nutrients causing apprehension for the dam and reef. The higher levels of electrical conductivity most likely generate from the salinity of the dam or the quantity of salt particles that are found in the water (Ryan, 2018)
methods of direct count, viable count, and turbidity study. Abstract The goal for using all three enumeration techniques is to not only understand direct count, viable count, and turbidity study, it is to also understand the advantages and disadvantages of each so that researchers can use them in the most efficient ways when studying microorganisms. The idea was that if the direct count gives a certain number of microorganisms, then the viable count and turbidity study should also give us similar number
Turbidity and algae are removed from raw waters by screens, gravel filters and slow sand or rapid gravity filters. The difference between slow and rapid sand filtration is not the speed of filtration, but in the underlying concept of the treatment process. Slow sand filtration is essentially a biological process whereas rapid sand filtration is a physical treatment process. Screens Screens are effective for the removal of particulate material and debris from raw waters and are used on many surface
Forest fires or better known as wildfires are one of the most devastating events that could happen to anyone whom reside where they may occur. The imagery of forest fires portrays them as one of the most horrific things that could happen to humanity due to all the materialistic damage that they cause. News outlets show keep us updated on how long the fire burns and how many firefighters lose their lives battling these fires. In the years, 2011, 2012, and 2013 five federal agencies spent 1.73 million
soil productivity” (Soil Quality). Furthermore, soil erosion has devastating effects on aquatic ecosystems. Erosion leads to the pollution of waterways with sediment. The addition of sediment to a waterway decreases the depth and increases turbidity. Turbidity refers to the clarity of the water; the more turbid a waterway the less light can penetrate. This poses problems to aquatic life because the less light that can penetrate the surface, the lower the capability of plant
The Hudson River is New York’s largest river and much of its population lives around it. The head of the Hudson River is in upstate New York in the Adirondack Mountains and flows south to New York City. The river’s water eventually ends up in the Upper New York Bay and then the Atlantic Ocean. From beginning to end, the river flows 315 miles. Between 1947 and 1977 the General Electric Company discharged 1.3 million pounds of PCD into the Hudson River. As a result, even still today, the river is still
many different factors. Physical factors such as weather is a major issue. It’s an issue because it changes, and is not always the most credible data tests. This can affect different chemical factors of the water’s quality such as the pH and turbidity. The turbidity was 5 JTU was clear, but the DO level was 4ppm which is liveable, but very low. Also, the phosphat level was 2.75 ppm which is very high seeing as normal is below 0.03. Biological factors were also a problem because of the organisms living

Water: it is the driving force behind our planet. It is what makes life possible on earth. Water is what runs so many other environmental and biological systems on our planet. But to know how water drives our planet, we first need to know what is the driving force behind water. Water has the ability to absorb and release vast amounts of heat. This helps to keep the earth’s surface thermostatic. This also helps regulate weather patterns. Heat currents travel from the equator to the poles and then
Bacteria are small microorganisms that are found in all environments, they are the building blocks of all life. Bacteria are ubiquitous, they are present everywhere. Bacteria have been present on earth for approximately 3.5 billion years (1, p.1). Bacteria serve a variety of different functions that are ultimately vital to life but can also threaten human life. Bacteria may be small, but our life is dependent upon their activity and growth (1, p.1). Since bacteria are so small and our life is dependent
Water quality can be described as the measurement of the condition of water relative to the requirements of humans, animals and plant’s need. When we talk about water quality testing, we are highlighting a critical piece of natural observing for civil engineers in order to create a specific structure or decision. At the point when water quality is poor, it influences almost every single form of life in our planet; going from plants to animals and thereon. Hydrology, in the other hand, is the study
