“…Many studies on coliform bacteria have focused on sanitation or disease [2][3][4]. Studies treating coliforms as a water quality factor have addressed distribution and detection [5][6][7][8][9], analyses of discharge characteristics [10,11], and model development and simulation [12][13][14][15][16][17]. Various research topics have been also investigated, such as bacterial source tracking related to the occurrence of coliforms [16], the transport and fate of coliforms [17], and bacterial indicator testing [18].…”

“…Various research topics have been also investigated, such as bacterial source tracking related to the occurrence of coliforms [16], the transport and fate of coliforms [17], and bacterial indicator testing [18]. However, most focused on marine systems [7,13,14,[17][18][19][20][21][22][23] rather than on rivers [6,9,11], because coastal zones are often used for recreational purposes and are the final repositories of pollutants. Some studies have used regression analyses to determine the relationship between coliform bacteria and water quality factors in rivers [24][25][26][27].…”

Artificial structures installed in rivers can change the natural physical, physiochemical, and biological characteristics of the rivers. Coliform bacteria are important water quality indicators, related to human health. This study investigated the relationship between coliform bacteria and water quality factors at eight weir stations constructed in the Nakdong River, a major river in South Korea. Fifteen water quality factors were analyzed at these sites from 2012 to 2016 using correlation and multiple regression analyses. The results for all stations confirmed the analytical validity, with high adjusted R 2 values of approximately 0.6 and 0.8 on average for total and fecal coliforms, respectively. The results showed influential water quality factors affecting the concentration of coliform bacteria at weir stations. Specifically, total coliforms were mostly affected by organic matter and fecal coliforms were mostly affected by phosphate phosphorus and suspended solids. Rainfall was the most influential factor affecting both coliforms. Further, both coliforms were negatively affected by organic matter below the Dalseong weir in the mid-to downstream area of the Nakdong River. A positive relationship with phosphate phosphorus was indicated at all weir stations. To the authors' knowledge, this kind of study has never been attempted so far. Thus, the study results can provide important information on influential water quality factors related to coliform bacteria, especially in the Nakdong River, creating a foundation for future water quality management.

The Akosombo Hydroelectric Power Plant (AHPP) is one of the largest man‐made lakes in the world. The impact of the dam after its construction on living organisms and people is not known. This paper offers new insights into our understanding of how the lake affects water quality for living organisms and people living downstream of its tailrace at different spatial levels. Water samples were collected to determine physicochemical and bacteriological parameters at fifteen strategically chosen sampling points. The data were analysed in the laboratory for certain physicochemical and biological parameters. About 95 questionnaires were also administered at Abume to households to ascertain their concerns with the water from the dam. The results indicated that the operation of AHPP has statistically significant effects on pH, Dissolved Oxygen (DO), faecal coliform and total coliform. The DO and total coliform did not rejuvenate by the 1km tailrace distance of the study. However, pH rejuvenated at a distance of 750 meters. The people also point out that the quality of the river at Abume is not safe for drinking and living organisms. The study concludes that water from the AHPP downstream is a satisfactory source of raw water that can be treated for domestic use. The water can also not support large fish species like tilapia. The study recommends that cage fishing should not take place close to the tailrace. The Volta River Authority and the government should provide potable drinking water to the communities affected by the construction of the dam and new sustainable turbines should be employed to manage the dam.
