Conodoguinet Creek Polluted Lab Report

Decent Essays

On October 7, 2015 the orange team from East pennsboro middle school conducted extensive testing regarding whether or not the Conodoguinet creek is polluted. The team tested for, number of crustacean, macroinvertebrates, alkalinity , velocity,and eutrophication in the water. The findings can dismiss the assumption that the Conodoguinet creek is polluted. Also the findings can shed light about how clean the creek really is. For example the knowledge we know states that organisms that belong in the group 1 category can not survive under any polluted environment. With this knowledge the team tested this by finding and counting the organisms. Out of 100 organism 65 …show more content…

The velocity of the water or speed of water determines the dissolved oxygen levels in the water. The higher amount of dissolved oxygen the better the water is to the aquatic life in the creek. Because fish need dissolved oxygen to survive, low level of dissolved oxygen will be bad for aquatic life. Also the creek would not be healthy with low amounts of dissolved oxygen. The results of the test had an average of 9.8 . This is the average number a normal and healthy creek should have. All in all due to extensive testing by Epasd’s orange team. We can conclude that the Condiment creek is not polluted. Due their tests of organisms, phosphates, and alkalinity, and dissolved oxygen levels. All of these tests gave numbers that a healthy creek would have. Critter count we counted the little critters that live under rocks. then we sorted them into 3 different groups. group 1 they are pollution sensitive and found in good quality water. group 2 are somewhat sensitive and can only live and good are medium quality water. group 3 are tolerant to pollution and can be found in any quality water. Water velocity we also measured the water velocity and found out the creek goes faster the if the water
