Pond Water Essay

The dissolved oxygen levels are much higher in this experiment than in the previous experiment.

-If there is more dissolved oxygen in the water, there will be more fish present in the area the water sample is taking from.

The U-high freshman biology class designed an experiment to test the question; based on the number of micro invertebrates, what is the water quality of the U-high creek? On 9/22/14, the day of the experiment, the conditions were recorded at 10:05 AM. The temperature was 55 degrees with a 6 mph wind, and 62% humidity. One of the observations of the creek is that there was some garbage and trash on the banks, although there was minimal amount. Another observation was that there was run-off leading into the creek from roads, nearby parking lots, and neighboring yards. There were about 40 small fish, only about 2-3 inches long swimming north against the current. The water was also very clear, and the bottom was clearly visible. Based on the observations

The problem that needed to be solved for this experiment was, “How are organisms able to survive and function with proficiency despite metabolic activities that have the disastrous ability to alter pH from a neutral to an acidic or basic environment?” This question needed to be answered by testing different biological materials, as well as tap water, in order to find out what allows modern day organisms to survive such hazardous conditions. A hypothesis that was formulated before experimenting was, “If type of substance is Tap Water, then the changes in pH will be more drastic because water, considered neutral on the pH scale, doesn’t contain a component that will prevent such a change, unlike the content of a buffer solution.” The independent variable for this experiment was type of substance, evidently because this was the part of the experiment that was constantly being changed from trial to trial. The dependent variable for this experiment was pH of the substance because the pH constantly changed depending on the type of substance was being experimented with. The control of this experiment was the tap water and buffer solutions, as the results of the data from the biological materials were constantly compared to the data from both of these solutions.

The waterways can be divided into categories of water that has been affected by the Summitville mine and water that has not been affected. Based on the location of the waterways, the Beaver Mud Dump, the Headwaters of Wightman Fork, Schinzel Flats, Wightman Fork below mine, and the small creek from tailings pile would be directly affected by the contamination initiated by mining activity, while the Cattle Guard, Iron Creek, Alum Creek, Bitter Creek, and waterways around the Alamosa River would not be affected or as affected by the mining activity (refer to Figure 1). From the data collected this year, it can be inferred that the Beaver Mud Dump is by far the most metal-polluted body of water in the area; though the waterways affected by

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

We also did the Nitrate tests. For the results, we received 2.0 or less. That means the water is in good quality. Next we did the Dissolved Oxygen test. We obtained results that were in 10.0, 11.0 and 12.0 which means that the water is good quality. But the first group who did this test gathered a 9.0 which is fair. This means that the water is kind of polluted. The rest of the tests we did were testing the acidity and alkalinity. The results were positive, but for the first trial of the pH meter reading, the results were fair.

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

A healthy pH in water for aquatic organisms ranges from 6.5 to 8.2. Our water samples ranged from 6.5-8.5. Although there did not seem to be any significant differences in our results of freshwater versus seawater samples, the most notable contrast seemed to be that the freshwater obtained a pH of 8.5. This can be a result from metal pipe corrosion which produces high levels of copper, lead and iron in the water. Corrosion can occur due to low pH, so operators will change the pH to comply with the high levels of these elements, thus making the water moderately basic (LaMotte

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

Temperature: I can’t control the room or water temperature of the area studied. This may influence the amount of dissolved oxygen in water. However, as the measure are done at the same time I expect the temperature to be similar.

All of the types of water began with the same amount in both environments; 25 mL of water. Along with the pH changes, the estimates of the pH of each type of water was not correct for the most part. The hypothesis for the pH at room temperature was mainly incorrect. The hypothesis was that Fiji would have a neutral pH of 7, 7/11’s spring water would be slightly acidic, Quincy’s tap water would be slightly basic along with Poland Springs and Aquafina. The hypothesis was mostly proven wrong. Fiji’s water was slightly basic with a pH of 7.8, 7/11’s water was slightly acidic at a pH of 6.2, Quincy’s Tap Water was not slightly basic, but slightly acidic at a pH of 6.7. (Quincy’s tap water was the closest to the neutral pH of water that is 7.0) Poland Springs’ pH along with Aquafina was not basic, however they were both slightly acidic. Poland Spring’s pH was 6.5, and Aquafinia’s pH was 6.6. However, something that was observed and considered intriguing was how the amount of evaporation that occurred was not the same for each type of water, and it certainly was not the same in the different

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
