All living organism depends on water and its quality. Human activities and the ways we use our river and streams and the land around affect the quality of the water we drink, cook with, and use for recreational opportunities (Erwin, Hamilton, 2002). It also affect the health and diversity of aquatic plants and animals and the beauty of our rivers and streams (Erwin, Hamilton, 2002). Many rivers and streams are significantly polluted all around the world (Lenntech, 2016). Industries and cities, agricultural and domestic activities are three major sources of pollution that are usually concentrated along the rivers(Lenntech, 2016). According to the Environmental Protection Agency, the main sources of water pollution are industrial waste with harmful chemical and toxic substances that is openly thrown in rivers water, sewage and wastewater from homes, agricultural runoff with fertilizers and pesticides, eutrophication which is the massive growth of algae, and dumping of litter like plastic, rubber, paper and trash in water bodies. As a result, aquatic life and surrounding environments such as trees and shore animals will suffer and be harmed. 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 Agency website, the normal level of pH for river water is around 7.4. A high pH can make a river inhospitable to life and a low pH will be harmful to small fish and insects (Lenntech, 2016). Turbidity measures the water’s clarity. High tur...

... River is more cloudy than the Inner Harbor. Because of this, I reject our hypothesis that the Inner harbor of Baltimore water samples will be more polluted that the Middle Patuxent River water samples.

During our experiment, many errors could have occurred. We collect the water samples from both sites during the weekend and we had to wait until Wednesday to test them in lab. Since we didn’t test the water samples right away, it could have affected our results. Another error could be that the bottles we used to collect water samples might have not be clean enough. Also, our water samples had residue in them that could have affected the testing results. For future experiment, I would suggest testing the water sample right away to get accurate results. A new experiment could test for organisms that might affect the water quality with their presence or fecal waste.

The Role of Water in Living Organisms Essay

- The Role of Water in Living Organisms Water is one of the most abundant molecules on planet earth; it is found in vast amounts not only in earthly enviroments (oceans, lakes and rivers), but is also present in the atmosphere, and as solid ice in the two poles. Consequently it is rather logical that water plays an important role in biological life: the origins of life occurred in water and life itself wouldn't be able to continue in it's absence . I will now describe the structure of a water molecule....   [tags: Biology Essays]

The Role of Water in Living Organisms Essay

- Water is essential to life, without water life on Earth would not exist. Water is a major component of cells, typically forming between 70 and 95% of the mass of the cell. This means that we are made from approximately 80% of water by mass and some soft bodied creatures such as jellyfish are made up from up to 96% water. Water also provides an environment for organisms to live in, since 75% of the Earth is covered in water. Water is a simple molecule, which is made up of two hydrogen atoms and one oxygen atom, forming H2O....   [tags: Biology Essays]

An Account of ATP Production in Living Organisms Essay

- An Account of ATP Production in Living Organisms All cells must do work to stay alive and maintain their cellular environment. The energy needed for cell work comes from the bonds of ATP. Cells obtain their ATP by oxidizing organic molecules, a process called cellular respiration. Glucose is the primary fuel molecule for the cells of living organisms. Every living organism must do cell respiration. Most eukaryotic organisms are aerobic. Aerobic respiration is required in order to obtain enough energy (ATP) from the oxidations of fuel molecules to survive....   [tags: Papers]

Essay on Drinking Water: We Need Water Conservation

- Our planet is covered with water. More than 70 % of the Earth’s surface is covered with lapping tides or splashing waves.  However, most of the water that covers Earth’s surface contains salt  “Water, water, everywhere, nor any drop to drink”(Coleridge). This quote from The Rime of the Ancient Mariner illustrates the reality of our water situation here on Earth.  The sea of water that surrounds us seems abundant enough to last forever, but it isn’t something we can actually use to sustain ourselves....   [tags: Potable Water Resources 2014]

Pollution of Drinking Water Supplies Essay

- It is widely known that water covers almost three-quarters of the Earth's surface. However, it is not widely known that more than 99 percent of Earth's water is unusable by humans and many other living things. Less than one percent of water which supports most of the forms of life we are familiar with. Unfortunately, that one percent of fresh water becomes more polluted every year. The pollutants that fill our waterways each year are largely unknown. Water pollution comes from a number of unique sources, such as industrial waste, urban storm-water, agricultural runoff, various household chemicals and even nuclear waste....   [tags: Drinking Water Contamination]

Drinking Water Sustainability Essay

- Introduction The importance of water, in relation to the Earth and its inhabitants, can only be rivaled by the importance of oxygen. Living things depend on water in their habitat. However, the abundance of water is not as important as the usefulness of the water. Much of the Earth is made up of this unique liquid combination of hydrogen and oxygen, but the amount that can be used for human consumption is less than one percent (Boland, 2003). In essence, humans use potable water, water that is suitable for drinking and cooking, to satisfy their basic needs....   [tags: Potable Water Scarcity]

Essay Water Pollution Kills Sea Life

- ... When the algae continues to grow it blocks the sunlight from reaching the plants and the plants end up dying and sinking to the bottom. While bacteria uses up oxygen making the water uninhabitable for sea life. Trash is also a key factor in water pollution. Every trash can cause damage for example when there is plastic in the ocean or on the sandbank, sea turtles may think its food so they will eat it.

Valuing Ecosystems and Their Services Essay

- An ecosystem refers to dynamic communities of living (abiotic) organisms like animals, fungi plants or bacteria that interact with each other and share the environment with non-living (abiotic) factors like water, soil, oxygen, sunlight etc. These abiotic factors allow life to happen in the ecosystem. All life depends on non-living or abiotic factors to survive, however the non-living factors can exist without them. Ecosystems vary hugely in size as it can be an entire rain forest with thousands of species or a puddle containing water, algae bacteria and other microorganisms....   [tags: organisms, environment, survive]

Freshwater Ecosystems Essay

- Introduction An aquatic ecosystem is an ecosystem takes place in a body of water, which has a community of organisms that depend upon each other to live and function. Three major ecosystem functions are energy flow, nutrient cycling, and biodiversity. Energy flows through an ecosystem and trophic levels from primary producers, which use solar energy in photosynthesis to synthesize complex organic substances (Reece & Campbell 2011, Lindeman 1942, & Gaston 2000). Solar energy is the basis from which all life in an ecosystem depend upon (Lindeman 1942)....   [tags: aquatic ecosystem, organisms, substance]
