The Yardantsi Reservoir, Gusau Nigeria serves multitude of purposes for the Gusau populace. It is the main source of water for domestic purpose, irrigation, and fishing. The reservoir receives both organic and inorganic waste through runoffs and seepage from the catchment areas. The physico- chemical parameters of the surface water were investigated monthly from May, 2015 to April, 2017. Samples were collected from five sampling stations and analyzed using standard procedures for examination of water and waste water. The data obtained was subjected to multivariate analysis using Microsoft office excels and SPSS. The results showed the following mean seasonal variation of surface water temperature (26.62±0.34– 30.12±0.17ᴼC),transparency (48.82±1.08- 22.07±0.87cm), mean depth (2.12±0.05-2.65±0.04m), pH (7.61±0.15-7.96±0.13), electrical conductivity (186.32±3.84- 108.05±5.43µS/cm), total dissolved solids (96.00±1.95- 63.70±3.68mg/L), dissolved oxygen (7.80±0.11-6.91±0.10mg/L), biochemical oxygen demand (2.71±0.09-2.48±0.05mg/L), alkalinity (40.57±0.69–27.87±0.51mg/L), hardness (59.20±1.01– 32.18±0.94mg/L), NO3-N (2.28±0.08-4.44±0.07mg/L), PO4-P (123.72±1.44-173.48 ± 2.78 mg/L), sulphate (31.62±1.45-71.80±1.82mg/L)  and chloride (74.08±1.67- 37.64±0.96mg/L) for dry and rainy seasons respectively. The results revealed that a highly significant seasonal variation (p<0.01) was exhibited in all parameters with the exception of pH which shows no significant seasonal variation (p>0.05) and biochemical oxygen demand, which shows a significant seasonal variation (p<0.05). The results of this survey showed that the parameters observed indicated that most of them fall within the recommended range set by World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ).Keywords: Dissolved oxygen, electrical conductivity, pH, reservoir, temperature

Analysis Of Results

Variations in the water quality of the Imo River estuary was investigated by measuring values of selected physico-chemical parameters. Samples were collected bi-monthly between April 2015 and March 2016, covering the dry and wet seasons of the year. Three stations were selected: upstream (Kalibiama), midstream (Opobo) and downstream (Queenstown). Analysis of results showed that physico-chemical parameters were affected more on seasonal than spatial scale. Principal component analysis carried out indicated that values of most of the parameters recorded within the stations clustered together. On the other hand, dispersed values were recorded in months and seasons with significant variations at (p≤0.05) among most parameters. The high spatial variations in phosphates, suspended solids and lead could be associated to human activities like laundry and waste disposal within Opobo and Kalibiama stations. While, high seasonal variability in most parameters could be associated with intense sunshine, cloud cover and tidal intrusion/dilution due to runoff. It can be concluded that nutrient fluxes due to nitrogenous fertilizers are not a problem within the estuary. However, chemical factors and biodegradable components which cause fluctuations in biological oxygen demand are more of the challenge.

Water is a must for all living things. Reservoir and lake water is used for a variety of purposes, including drinking water, agricultural, commercial, recreational, and aquaculture. However, due to rising population pressures, which has resulted in rapid urbanization, industrialization, and modern agricultural practices, water pollution has become a major issue in recent years. The water quality index is a single number that reflects overall water quality at a specific place and time. To compute, water quality index (WQI) we used Temperature, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (B.O.D), Chemical Oxygen Demand (C.O.D), Alkalinity, Electrical Conductivity, Turbidity, and Chemical Oxygen Demand (C.O.D), Nitrite-Nitrogen, Nitrate-Nitrogen and Hardness were the physico-chemical parameters investigated in this study. The water quality index is to transform complicated water quality data into information that the general public can use. The Water Quality Index was calculated using the Weighted Arithmetic Water Quality Index (WQI). The measured WQI was then used to assess the water quality in Rabale water body. The water quality index (WQI) of the lake was 49.813, 53.483, and 53.045 during the pre-monsoon, monsoon, and post-monsoon periods, respectively. When comparing seasonal variations, WQI values show that water status is fairly good during the pre-monsoon but is low during the monsoon and postmonsoon seasons, thus water from Rabale water body may be used for a variety of industrial purposes.

This study was conducted to measure the water quality parameters of old Brahmaputra River in Mymensingh district near Bangladesh Agricultural University to determine the water quality index (WQI) of the River Brahmaputra. Water quality focuses on various aspects of the physico-chemical parameters by which the quality of the water body can easily be elucidated. Three different locations were selected within the study area. Water samples were collected in April 2015 from these three locations along the river and analyzed for these physico-chemical parameters: pH, Dissolve Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammoniacal Nitrate (AN), Suspended Solids (SS). The values of these parameters were used to calculate the WQI based on the equation derived by the Department of Environment (DoE) Malaysia. The WQI was found to be 57.58, which falls in the class IV category and means that the water is “very polluted” and as of April 2015, this water is not suitable for public water supply, not suitable for recreational purpose, has limited potential for aquaculture but is suitable for irrigation.Progressive Agriculture 27 (3): 355-361, 2016

The aim of this work was to find the seasonal variations of physico-chemical properties of the Dejla Dewda reservoir. The physico-chemical characteristics have been studied and analysed in the present investigation during Nov 2016 to Dec 2017.Water samples were collected from three sampling stations, changes in the physico-chemical parameters of water, such as Water temperature, transparency, alkalinity, chloride, sulphate, nitrate, phosphate, Total dissolved solids (TDS), Biological oxygen demand (BOD), Dissolved oxygen (DO), Chemical oxygen demand (COD) and pH were analysed. The result was compared with the water quality standard of WHO. Between various physico-chemical parameters systematic calculation of average and standard deviation was done to compare the water quality level at different stations. During the investigation period of one year, 24 species of fishes belonging to 03 orders and 06 families were recorded. Therefore, monitoring of the water quality of sampling sites of Dejla Dewda reservoir should be done at regular intervals to facilitate the growth of fish species. It was observed during the study that this reservoir water is not much polluted and supports high diversity of aquatic animals.

Water quality plays an important role in maintaining plant and animal life. Lack of good quality drinking water and water for sanitation cause health problems. Water quality characteristics arise from a group of physical, chemical and biological factors. The dynamic balance of the aquatic system can be destroyed by human activities resulting in water pollution.Well water has traditionally considered as a safe resource of water for consumption without treatment and extensively used for individual water supply in rural and many urban areas.In this paper a preliminary analysis is done to explore the water quality of selected wells in order to correlate the effect of pollution on water quality at these locations. Water samples are collected from different regions of Vazhappally area located on central travancore of Kerala. These sites are important because people depend only on well water for drinking purpose. The samples are collected from ten locations and analyzed for chemical parameters such as pH, conductivity, salinity, turbidity, acidity, alkainity, hardness, total phosphates, dissolved oxygen, biological oxygen demand, total dissolved solids and Iron content. Samples are also analysed for coliform bacteria which cause pathogenic diseases. Remarkable differences are observed mainly in biological oxygen demand, acidity and hardness. Finally, an attempt has been done to correlate the observed chemical parameters and the waterquality standards.
