Essay On Water Science

Introduction: The purpose of this research is to determine whether there has been a change in the overall water quality of the Lake Tarpon Basin, and if so, whether the quality has improved or worsened. The variables that will determine whether the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). The expected changes are lower dissolved oxygen levels (from the already low levels), higher nitrogen levels (from the already high nitrogen levels), and the state qualifications still are not met for nutrients and dissolved oxygen (Levy, Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because the changes in water quality would be due to pollution, which relates to the question “How does human activity lead to the pollution of water stores?” The hypothesis that will be tested is that Lake Tarpon’s water quality will have worsened since the last measurements by Levy, Flock, Burnes, Myers, Weed, and Rivera in 2010.

“The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity (sic) of the solution. The letters pH stand for power of hydrogen and the numerical value defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.” (PH, 2002). The pH scale is from 0 to 14. When the pH is higher, the hydrogen ions are fewer and the substance considered alkaline. This means when a pH unit increases by one, there is a tenfold change in the hydrogen ion. For example, if a substance has a 7 pH, it has 10 times as many as hydrogen ions available as 8 pH. A lake having a water pH between 6.5 and 8.5 is considered to be neutral. Researchers tested Peckham Park lake water monthly from August 2015 to April 2016 for water pH levels. A water quality PH test strip taken from a jar and dipped into the lake. After a few minutes, the strip will turn a color and this color determines the pH. The jar the strips came in has a chart of the colors on the back which compared to the color on the strip. The lake tested monthly using the PH test strips, which show the pH level, hardness, toxic, etc. using color-change

The samples of unfiltered Rio Salado River water used in these experiments were collected from a site on the south bank of the river near S. 7th Ave. in Phoenix Arizona (see figure 1). The samples of water were collected by filling a three-gallon carboy by submerging it in the river. The carboy was then transported at ambient air temperature to the lab the same day it

Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).

Abstract: During this lab, the pH of water in soil from a man made garden, a deciduous forest, and a river bank were tested after leaving it in containers for one, two, and three hours, coming out to a total of three trials with three different soils all together. After testing the pH of the water when being added to the soil for the desired amount of time and comparing it to the original water with no soil added, is then when each pH difference was observed and recorded in a a notebook, while pictures were taken of the experiment being conducted.

According to The New York City Department of Environmental Protection, a minimum DO levels is mandated to be 4.8 mg/L and the pH level is mandated to be in between 6.0 and 9.5 for saline waters such as the Gowanus. We used these mandates as a guidance in this project. Low pH level in the Gowanus canal cause harm to species that live in the water, such as fish and low DO level would harm the plants that are in the water which also harms species that rely on the plants for food. For our Constraints, the filter should have to make the water less acidic than it was initially. The filter should also increase the quantity of oxygen that is present in the

To assess and analysis the long term trends and seasonal trends of Phosphorus in relation to the lakes system within the catchments.

For both ponds, the procedures are identical to each other. Submerged the YSI 55 DO Meter about 6 inches into the clear water to take an initial DO measurement at the surface, and did the same thing when it was lowered 2 feet into the water to take initial DO measurement at the bottom. The meter took the DO, % DO Saturation, and temperature at both the surface and the bottom of the pond. Four water samples were taken from the pond and collected in viewing tubes. Used the tube on the left side as a control and in the second tube, the group added Phosver 3 Phosphate Reagent

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.

Water is essential for life as we know it on earth. It is used by plants

Water is one of many hydrogen bonds and in being a hydrogen bond is a very strong bond. Hydrogen bonds are forces of attraction between hydrogens and electronegative atoms in two different molecules, these bonds usually have partial negative charged however in some mutations it may result differently. Freshwater creek is commonly tested, usually every march, with parameters including: DO, BOD, PH, water temperature, turbidity, dissolved nitrates, dissolved phosphates, ammonia and salinity/conductivity. Dissolved Oxygens otherwise known as DO, funnily enough is a measure of dissolved oxygen in water, by measuring DO scientists can tell us about the water and its quality. Oxygen is an essential part of life for any living creature to survive meaning it can be found underwater however is the oxygen drops below normal level creatures underwater die off due to lack of oxygen. DO levels can be brought up or down due to both natural and unnatural forces, an example of natural forces might be a result of migrant fish or water life taking up all the oxygen, an unnatural example can include runoff from farms or litter which will take up more space and oxygen. DO is usually

As I sat next to the loud river that was bursting out of the Sylvan Dam, I noticed the water was in an invariable battle with the rocks, crashing and thrashing against each other like medieval warriors scraping for land. I looked around the edges of the river to see the copiousness of colors from the trees contrasting the sinister blue water. The rapids put off a pleasant and dulcet sound that ultimately ended in me having to relieve some building pressure down the trail. After returning to my riverside view, I noticed that farther down the gleaming river, fish were jumping and flipping like delicious pancakes on a griddle. Making the split-second decision to fish, I sprinted to my 1999 black Chevy Silverado, unlatched the tailgate and snatched all of my waterproof fishing gear. Slipping on my Mossberg max 4 Camo Gander Mountain guided series waders is no easy chore. While looking like the most incapable human being ever I finally managed to slip on the foul scum smelling waders that I so dearly should have washed. Feeling like a professional mountain climber, I started scaling the steep inclement of the river bank. Stomping my insulated waders into the frigid dour murky water, I ventured my path out onto a construction of rocks forming a beautiful approach for spotting fish. I released my light green jointed shad Rapala from my St. Croix Legend Elite spinning rod and casted the shad into pooling backwater just off of my rocky approachment. Feeling the vibration of the shad through my rod, smacking against slime covered rocks and ripping through dense weedy areas. I felt aspirant to not get hung up on a rock resulting in a line break, I successfully retrieved my lure. After casting and reeling my line several times and just started zoning out, I was abruptly startled to hear a ruckus coming from the west side embankment. Glancing quickly back to the water to see where my lure was only to hear a loud splash coming from the same place where I first noticed the ruckus. Three deer, with golden brown fur coated enrolled into the water. Realizing that the leaders of the small herd were both doe’s and a younger buck eagerly followed. The buck had a nice six-point rack, with long tines and a wide spread. He kept his

This paper discovers the water budget for Berkeley, California in comparison to Terre Haute, Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters, where the majority of rain occurs and Terre Haute, Indiana where the rainfall is observed as consistently disseminated throughout the year evenly. This paper will also magnify geographic position, climate and elevation in contrast of the two cities that reflects the water budget outlined in Project 1: Water Balance defined in
