Conodoguinet Creek Pollution

1455 Words6 Pages

My 8th grade class went to the Conodoguinet creek to test if there was any pollution in the creek water. Before we went my hypothesis was, “If we go to the Conodoguinet creek and test the water, then the creek will have little to any pollution in it because we haven’t had a monstrous storm in the past few months so there wouldn’t be an excessive amount of acid rainfall or runoff” There are three types of macroinvertebrates ( an invertebrate fauna - animal of a particular region - that can be captured by a soo - which is a certain net or sieve - ) that we were looking for, Group 1 ( which is pollution sensitive - they cannot have any pollution- ), Group 2 ( which is somewhat pollution tolerant - they can live with some pollution-) and Group …show more content…

phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with. Dissolved Oxygen is another thing we tested for, that 's how much oxygen gets mixed within the water ( Ex. rapids - the white part of the rapids is the oxygen mixing with the water- .) We also tested how fast the water was moving or the ( speed/velocity. ) We were going to test it by using a bamboo pole with a string ( with a certain length ) and a bobber on the end and see how long it takes for the bobber ( from its full length ) to hit the bamboo pole. To find the actual speed of the water you take the length of the string divided by the time ( sec/centi

The variables measured are nitrate, nitrite, total phosphorus, ammonia and transparency. Harrison also states that river and Lake Eutrophication is a problem across most of Europe because of excessive nitrogen and phosphorus levels from agricultural, industrial and domestic effluents. Harrison states that natural organic matter is present in most natural eco systems.

Observation In Burns Bog And Watershed Park

783 Words | 4 Pages

As water contains hydrogen ions, it has a scale of acidity. Life can be maintained in pH levels between 6.5 and 8.5 (Ecoscope: For Sustaining Wetlands). If the concentration of hydrogen ions becomes too great or too small, it becomes difficult for the plant to survive. Photosynthesis uses hydrogen ions which changes the pH level of the soil. In Burns Bog, there is mostly peat and therefore, the soils can survive higher acidic measures.

Nitrates should be greater than or equal to one parts per million (ppm), phosphates should be less than or equal to .1 ppm, and the pH values should be about equal to seven. The dissolved oxygen in the river depends on the temperature, if the temperature is cooler than the dissolved oxygen levels will be higher, but the recommended amount of dissolved oxygen should be greater than or equal to five. For a healthy river the turbidity levels should be 120 centimeters

Conodoguinet Creek Is Not Polluted Essay

We found a little number of Phosphates and Nitrates in the water. That is healthy because these two chemicals are in fertilizers and detergents, they can harm the creek and all the creatures living in the creek. They get into the water through the eutrophication process. Bacteria eat phosphates and nitrates so that means there is a little number of bacteria in this creek. The dissolved oxygen level of the creek is high which is healthy.

ulimba Creek is the largest creek in Brisbane measuring to only 122km². It is located in the eastern and south-eastern areas of Brisbane and generally flows northwards into the Brisbane River. There are also a number of significant wetlands systems in the catchment in the upper and in the lower catchment. The creek is, at present, affected primarily by urban and mechanical advancement. In the past the creek hallway was broadly cleared for crops and after that grazing in the early moments of the most recent century with some remainder of vegetation remaining.

In addition, it was found that the Charles River is very polluted. The existence of midges and other worms prove nothing as these are group 3 macro invertebrates that are very tolerant to pollution and can exist in almost any kind of water. However, the existence of scuds shows something different, as this is a group 2 macro invertebrate, meaning it is only fairly tolerant to pollution. However, due to the relatively small amount of these and the lack of any group 1 macro invertebrates, it can be shown that the Charles River is very
