Discussion
The aim of this experimental report was to analyse and examine several water quality parameters including dissolved oxygen, water temperature and turbidity, in order to determine the overall state of health within Freshwater creek. Once the results from each parameter were collected, from both locations, it was that found they each had multiple interrelationships between each other as well as several anomalies which could have potentially skewed the final results.
It was initially decided at the beginning of the dissolved oxygen experimentation that a reading would be collected from two locations with different features, in order to present a representation of the specific amounts of dissolved oxygen in different areas. It was evident …show more content…
This reduction in water temperature can be seen particularly in location 1 where both an observation and analysis was made showing that the temperature and light was significantly lower in that location with a reading of approximately 27.1oC and 167.78 LUX, in comparison to the other location with a higher result of 27.2oC and 246.67 LUX. From these results, an assumption can then be made stating that the sun’s rays was particularly unable to penetrate the surface of the water in location 1, due to cloud and tree coverage which would then predominantly effect the data regarding the water temperature discussed above. This effect would then result in the water having a minimal fluctuation in terms of increasing the water temperature, which would then evidently rectify the results in regards to a decreased amount of dissolved oxygen in location 1, rather than the other area. However, although these results can patently suggest and provide evidence regarding the 1st location having a larger possession of dissolved oxygen than the second, it is particular imperative to recognise that the levels of turbidity do not scientifically agree …show more content…
This high flow rate has then subsequently caused the dissolved oxygen in both years to significantly increase with the saturation of oxygen in both May and September 2015 to reach 85 and 92% (App.5). In conjunction to the results achieved from this year’s sample with a dissolved oxygen reading of 80-81%, hence suggesting that the DO content within Freshwater creek was particularly greater in 2015. This was due to an enhanced flow rate (13.775s/10m) and decreased water temperature (approx. 22.5oC) compared to this year’s results with a flow rate of 17.39s/10m and water temperature of approximately 27.2oC. These results can then be scientifically supported due to the hydrogen bonds being particular weaker in cold temperature which eventually increases the solubility of the polar solute in a way where the molecules are enabled to interact, and thus dissolve more efficiently with atmospheric oxygen
