DPFinalSummary


 * Description of Mashamoquet State Park**
 * Mashamquet is located in Pomfret, CT
 * Historical uses of Mashamquet are the domain of the Mohegan Chief Uncas. Known for the stream of good fishing. Captain John Sabin build a house to serve as an outpost and the settlement gradually increased in size.
 * Hiking, swimming, picnicking, and camping are uses that people do today.
 * When we went the site was litter free, water was odor free, and alot of trees.


 * Data Collection Conditions**
 * During our field trip May 23, 2011 the weather was cloudy overcast and temp was 63 degrees.
 * water temp was 18 degrees C
 * my role was dissolved oxygen with Trevor.


 * Dissolved Oxygen**
 * Collect mid stream water into bottle with no air bubbles, 8 drops of Manganous Sulfate Solution in the bottle, and 8 drops of Alkaline Potassium Iodide Azide Solution. Then add 1g spoon of Sulfamic Acid Powder. A clear yellow or golden color will develop. Fill Tritration tube to 20ml with the fixed sample and cap. Fill the direct reading titrator with Sodium Thiosulfate solution so the tip of the plunger lines up with 0. Insert the Tritrator into the center hole of the tritration tube cap. Slowly depress the plunger of the titrator adding a drop of the Sodium Thiosulfate to the fix sample. Should get to very pale yellow. Add 8 drops of Starch Indicator Solution the sample should turn dark blue. Place Tritrator back and continue to add a drop until it turns clear again. The tritrator scale was 9.4.
 * Test results for a healthy enviroment should be between 7-11mg/l. Our result was 9.4 which is healthy


 * Water Hardness**
 * In the water test you had to test to see if there is any minerals in the water present in the water.
 * A test results for a healthy environment 121 to180 for healthy results for fish
 * The test at mashamoquet was 40 so the water was unhealthy.
 * it is unhealthy to fish in the water at mashamoquet.


 * Alkalinity**
 * What the alkalinity test is to find what the PH is.
 * Test results for a healthy environment is 20 to 200 mg/l
 * The test results for Mashamoquet are 20.6 and it is good.


 * Nitrate**
 * To find out the to see if it is healthy for fish.
 * The test results for a healthy environment is 7.0
 * The test results for Mashamoquet are 0.38

> whether the water is acidic or "basic" (alkaline). It is measured using an electrical probe sensitive > to hydrogen ion activity
 * Ammonia**
 * Test results for ammonia are often expressed as ammonia-nitrogen (NH3-N), or "nitrogen that was in the form of ammonia." In unpolluted, well-oxygenated freshwaters NH3-N levels are usually less than 1.0 mg/l. In CT, the maximum acceptable concentration of NH3-N, assuming a pH of 7.0 and a temperature of 250C, is 1.24 mg/l. In especially sensitive areas, like salmon spawning grounds, the maximum limit is lower (0.86 mg/l). As either temperature or pH change, the amount of ammonia needed to produce the same toxic effects also changes. If temperature or pH decrease, more NH3 is needed and the maximum acceptable concentration increases. Conversely, if temperature or pH rise, less NH3 is needed and the maximum limit decreases. The criteria for NH3-N concentrations at various temperatures, given a constant pH, are presented in Appendix D of Water Quality Standards (CT DEP 1992). For a description of the chemical reactions occurring in tests for NH3-N, see the section entitled "Chemical Reactions."
 * the test results for mashmaoquet was .25
 * The ammonia is lower than 1.0 mg/l for CT standards
 * PH Balance**
 * pH is a measure of the hydrogen ion concentration of water, which determines
 * The pH of most natural waters ranges from 6.5 to 8.5. for a healthy environment
 * Ph balance for Mashamoquet is an average of 6.8.
 * This ph balance is a healthy environment according to natural water range.


 * Environmental Impact**
 * Mashamquet was closed down last summer due to coliform bacteria. After several testings they thought some of the blame to the bacteria was from the run off from the rain.
 * they also thought that older houses with older septic systems might contribute to high bacteria.
 * if Mashamquet has high levels of bacteria than plants and animals will not survive.
 * Conclusion**
 * **THis is a tough question. Mashamoquet 's ph balance is healthy, dissolved oxygen was normal, water hardness was soft. However the the ammonia was low and alkalinity was high. The nitrates were very low too. Therefore when you at the whole picture Mashamquet is not completely healthy.**
 * we can try to keep Mashamquet by trowing away trash, picking up our dog crap, and septic system
 * Killingly is cleaner than Mashamquet don't have any running water into it.
