Abstract
Momentary changes in some criteria regarding the quality of water were examined by conducting field test and laboratory examination in Cole Mere during the summer months (June, July and August) of 2013. 10 locations were chosen (inside the lake) and each was sampled nearly one month away from the other. The average surface water temperature was documented in June, July and August samplings were 14.1 °C, 21.9 °C and 18.2 °C respectively. The variations in the average temperature were numerically notable (p=<0.001). The average absorption levels of Cholorophyll a were 9.3 μgl⁻ ¹, 15.2 μgl⁻ ¹ and 39.8 μgl⁻ ¹for June, July and August respectively and there was a noticeable difference observed between the months at p=0.001. The detected momentary change and the rising levels of summer chlorophyll a absorption are exact evidence of eutrophic estate. However, no notable variations were observed regarding pH and declined oxygen between the months.
Highlights
With the increase in the population of the world, the demand for water has increased and the quality of ground and surface water keeps on decreasing due to the development of the cities and industrialization
In Europe and most other part of the world, afflictions caused by human life has been the primary issue negatively influencing surface water quality leading to eutrophication, acidification, adjoining of toxic elements, material fluctuations and destruction of coastal residence (Heckrath, Rubæk et al 2007) and as a result eutrophication has been invariably considered as the most significant issue negatively influencing surface water quality which is closely linked to public health interests, economic forces, ecological and aesthetic destruction
Other problems that arise as a result of eutrophication consist of deficiency of oxygen and failure of the water to assist marine life, fish kills, deterioration of biodiversity; deficit in water quality for leisure, agricultural, industrial and drinking objectives (McDowell and Hamilton 2013)
Summary
With the increase in the population of the world, the demand for water has increased and the quality of ground and surface water keeps on decreasing due to the development of the cities and industrialization. The lakes are typically small, lowland with their depth varying from 1 to 31m (Usman, Aliko et al 2015) They are positioned in bays in the thick mantle created as a result of melting of ice-blocks which are amassed in the area dating back to 14-16000 years in the late Devensian era, and many bays in the region are related to glacial amass compilation. Reference (Moss, Barker et al 2005) accounted that the Meres discovered in the North West Midlands of England exists a total number of lakes of high preserval importance, despite being impacted by high nutrient masses produced from the agricultural activities and population habitations. Despite the correlation of meres with eutrophic criteria for many decades, the great absorbtion and significant change to marine plants have occured over the past 50-100 years
