Poor Water Quality

Water quality, particularly coastal areas, is systematically tropogenic. The decline in water quality is caused by industrial waste pollution, soil erosion carried by the river, and the depletion of mangrove areas. The decrease of water quality can affect the fishery cultivation activities that exist in the region. It also affects the quality of the cultivated fish. Fish cultivated in ponds with poor water quality can be harmful to the health of the people who consume the fish. One effort to manage the feasibility of pond waters is by identifying the quality. The purpose of this research is to know the profile of pond water quality and to know the diversity potential of aquaculture. Based on the nature of the problem this research is a field research, while the purpose of this study is descriptive and explanatory research. The method used in this research is research by using survey method. Aquatic profile results are essential to improve the quality and quantity of Fisheries, especially in diversifying fisheries.

The quality assessment of watercourse, located in a highly urbanized area was the goal of research. The SłuŻewiecki Stream, which flows in the southern part of the capital city of Warsaw is the subject of study. The aim of the research was to determine the tendency of the water quality changes in the SłuŻewiecki Stream, flowing in the highly urbanized area and being a sink of the non-point and industry sources of pollutions as well as the surface runoffs which comes from its catchment. The field research was conducted along the entire length of the stream in 2015 and 2016. The water samples were collected monthly from a depth to 20 cm. Water quality tests were carried out in accordance with the valid analytical methods. The obtained results point to poor water quality. Therefore it can be conducted that the development and use of the direct catchment is the one of main factors affecting the water quality in SłuŻewiecki Stream. The tributaries, often not inventoried, from built-up, populated areas, are the most polluted. Tributaries contain large amount of organic compounds and nutrients.

Present study points out the impact of Lockdown on the health of the Yamuna river at Delhi stretch by comparing prelockdown and Post-lockdown period by studying the reports of pollution monitoring agencies. Delhi segment of the Yamuna is highly polluted, where alongwith domestic sewage a huge quantity of industrial waste is being discharged continuously without proper treatment. Pre lockdown (March 2020) water quality parameters at three sampling stations named as Palla, Nizammuddin Bridge and Okhla barrage U/s in Delhi were, pH were 8.7, 7.3 and 7.2, DO were 17.1 mg/L, not detected in later two sites, BOD were 7.9 mg/L, 57 mg/L and 27 mg/L and COD were 28 mg/L, 90 mg/L and 95 mg/L respectively and postlockdown period (April 2020) the pH was 7.8, 7.2 and 7.1, DO was 8.3 mg/L, 2.4 mg/L and 1.2 mg/L BOD was 2 mg/L, 5.6 mg/ L and 6.1 mg/L and COD were 6 mg/L, 16 mg/L and 18 mg/L respectively. The study of these parameters at three sampling stations reveals that the lack of industrial pollutants discharging due to nationwide lockdown for COVID-19 pandemic had positive effect on water quality of this river. Water quality could be maintained by planned establishment of industries and setup of ETP with without gap between generation and treatment.
