This paper deals with the physico-chemical parameters of the Titrigachhi daha. The maximum air temperature was recorded in rainy season but the water temperature was maximum in summer and lowest in winter season. Transparency, pH, dissolved oxygen, total alkalinity, total hardness were maximum in winter season. Free carbondioxide, chloride and biological oxygen demand were maximum in summer season. The minimum transparency, total alkalinity, total hardness and chloride were recorded in rainy season. Dissolved oxygen and pH, was minimum in summer season. The minimum carbondioxide and BOD were recorded in winter season. Air temperature, water temperature, free carbondioxide, and biological oxygen demand showed positive and significant correlation with each other. Similarly, transparency, pH, dissolved oxygen, total hardness showed positive and significant correlation with each other. Total alkalinity showed positive and significant correlation with chloride.

Dry And Rainy Seasons

The present work was conducted by monitoring the water from twelve major tin mine ponds water in Plateau State, North Central Nigeria (Bokkos, Barkin – Ladi and Jos – South) used for irrigation. Their quality was assessed in terms of physico-chemical parameters for dry and rainy seasons. The physico-chemical parameters such as; Turbidity, pH, Temperature, Electrical Conductivity (EC), Cation Exchange Capacity (CEC), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total alkalinity (TA), Total Hardness (TH), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Phosphate (PO43-), Sulphate (SO42-), Chloride (Cl- ), Fluoride (F-), Sodium (Na+) and Potassium (K+)  were investigated to ascertain the water quality for irrigation purposes. Water quality parameters with regards to its use for the purpose of irrigation such as FAO/WHO/FEPA standards satisfy the requirement for use in agriculture. However, turbidity which ranged from18.1 – 27.4 and 15.9 – 18.8, dissolved oxygen 20.9 – 26.3 and 20.2 – 27.4 mg/L, Total alkalinity 101 – 134 and 122 – 167mg/L, total phosphate 6.3 – 8.9 and 6.5 – 10.5 mg/L, BOD 7.4 – 23.8 and 7.2 – 29.2 mg/L, potassium 1.13 – 1.18 and 3.81 – 4.63 mg/L both in dry and rainy seasons, respectively were found to be above the irrigation water standard limits. The study therefore recommends that the mining pond water should be used with caution as some of the parameters are liable to be toxic to the irrigated crops. The positive correlation exhibited among some of the parameters examined is a clear indication of a common relationship between these sources of water.

Itahari Sub-metropolitan pond is located in the centre of the city. Influence of variations in physico-chemical parameters on aquatic flora and fauna especially in fishes brought strong stress on fishes and increases the incidence of diseases leading to high mortality. Due to lack of adequate knowledge about it, productivity of ponds is very low. In the present study, maximum and minimum variations and correlation between different physico-chemical parameters - air temperature, water temperature, pH, turbidity, total dissolved solids, dissolved carbon dioxide, ammonia, dissolved oxygen, biological oxygen demand, chloride, total alkalinity, total hardness and phosphate were taken into consideration. The water quality of fish ponds were normal except high fluctuation of chloride 4.0 - 44.87mg/l and ammonia 0.48-13.6 mg/l during manuaring period and casual addition of wastes like toilet cleaners, caustic potash etc.. Due to sudden fall in DO less than 4 mg/l during April and May, 2014 and increment of ammonia after addition of toilet wastes in Sept.19, 2015 ; mass mortality of fishes Labeo rohita, Cirrhina mrigala, Hypothalamichthys molitrix, Aristichthysnobilis occurred in the study site.

Today the environment has become harmful for the health of living organisms due to excessive pollution and contamination of natural resources. The present investigation has been carried out with the objective to assess the water quality of the Gobind Sagar Lake, Bilaspur, Himachal Pradesh (India) using physico-chemical parameters with heavy metals of the lake. For this study, three sampling sites were identified and samples from different sites were collected in summer season and important parameters [Water Temperature, pH, Total Hardness, Dissolved Carbon Dioxide (CO2), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Chloride, Total Alkalinity, Total Dissolved Solid (TDS)] with heavy metals [ Lead (P), Copper (Co), Iron (Fe), Cadmium (Cd), Nickel (Ni) and Manganese (Mn), Chromium (Cr) were analyzed. The results revealed that the different conditions of Gobind Sagar Lake in different sampling stations showed fluctuations in some physico-chemical parameters and also in heavy metals. These result depicted that water of lake was polluted in the form of nutrient enrichment which is due to agricultural activities and its runoff in and around catchment area of the lake. There are other many ways that things can end up in the lake as the free style way of disposal of industrial and domestic effluents etc. Results of studies on heavy metals in pollution are well documented revealing the toxic effects of these metals on aquatic organisms.

Drinking Purpose

As we all know that water is the most precious compound found in nature.It covers about 71% of the earth surface. About 97.3% of water is contained in the great oceans that are saline and 2.14% is held in icecaps glaciers and in the poles, which are not useful. The remaining 0.56% are found on earth which are useful for general purpose. Out of which Groundwater is one of the purest form of water available on this earth. It has been estimated that approximately one third of the world’s population use groundwater for drinking. This project is done in knowledge to get the analysis of various physico- chemical parameters such as pH, Turbidity, TDS, Total Alkalinity, Total Hardness, Chloride and Dissolved Oxygen of Gorakhpur city in view to ensure the groundwater to be fit for drinking purpose or not . About 20 samples were collected from India Mark-II Hand Pumps and Shallow Hand Pumps of various locations of Gorakhpur city and tested. After the analysis of various physico - chemical parameters of the samples collected , the groundwater found to be within permissible according to BIS 10500 – 2012.
