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.

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

Seasonal variation of physico-chemical variables of Oguta Lake, Nigeria was studied. Results obtained using standard analytical methods indicated that in the rainy and dry seasons (July and August) and (October and November), 2014, iron (Fe; 1.401 mg/l in November) was the overall metal observed in the lake, while mercury (Hg) was not detected throughout the period of study. Heavy metals concentrations observed were higher (not significantly) during the dry than the rainy season. The values observed for dissolved oxygen (DO), biological and chemical oxygen demand (BOD and COD) were within WHO permissible limits. The above evidence revealed that there was signs of heavy metal (Fe) pollution of the lake, and steps must be taking for constant monitoring of anthropogenic inputs into the lake.

The present study examined some physico-chemical characteristics (temperature, pH, total hardness, dissolved oxygen (DO), total dissolved solid(TDS), conductivity, transparency, biochemical oxygen demand (BOD), acidity and alkalinity) and some heavy metals (Fe, Zn, Cu, Cd, Cr and Ni) concentration of Stubbs Creek, Ibeno, Akwa Ibom, Nigeria between August 2014 and July, 2015. Six sampling stations (Mkpanak, Okpot Ikot, Ebana Mbri, Esit Eket, Okpuk and Ikot Ebia Anam) in Stubbs Creek were selected. Water samples were analyzed using APHA-AWWA-WPCF methods while heavy metals in the water samples were digested and determined using UNICAM 939 Atomic Absorption Spectrophotometer (AAS). The mean values of water parameters of Stubbs Creek are: temperature (27.22 ± 0.230C); pH (6.83 ± 0.13), DO (3.86 ± 0.20 mg/L), BOD (2.84 ± 0.11 mg/L), conductivity (522.23 ±69.12 µScm-1), TDS (288.83 ± 39.50 mg/L), transparency (0.86 ± 0.05m), alkalinity (95.51± 6.44mg/L), acidity (97.03±7.45) and total hardness(12.11±1.55).Only TDS, conductivity, alkalinity and total hardness showed significant (p<0.05) spatial variation across the sampling stations. However, the values of temperature, TDS, conductivity, alkalinity and total hardness indicated significant seasonal variation. Similarly, there were no significant (p<0.05) spatial and seasonal variation in the values of heavy metals recorded across the sampling stations. All the physico-chemical parameters and heavy metals in this study are below the maximum permissible limit recommended by WHO. The result showed that Stubbs Creek is less polluted at present and safe for the biota. However, responsible use of the water bodies by all and sundry should be maintained in order to preclude problems common with effluents discharge.

A study to examine the effect of depth and distance of the boreholes from the septic tank on physico-chemical parameters of the borehole water consumed in Dar Es Salaam, Tanzania was conducted. Samples were collected from 48 boreholes in Ilala, Kinondoni and Temeke districts and subjected to pH, B.O.D (Biological Oxygen Demand), total hardness, copper and lead analyses in relation to safety and quality levels set by WHO and TBS. Analysis by R-statistics indicated that pH and B.O.D significantly (p<0.05) decreased as the depth of borehole increased, whereas total hardness was significantly (p<0.05) higher in very deep boreholes than the other heights. Total hardness and pH were not significantly (p>0.05) affected by distance between septic tank and borehole and the B.O.D levels were significantly higher in the borehole water situated near the septic tank than those which were far. Based on the physico-chemical characteristics of water, 25% of the samples did not comply with WHO and TBS specification limits while 75% complied, most of which had shallow depths and were situated near the septic tank. It may thus be concluded that both the distance and the depth between septic tank and borehole influenced physico-chemical characteristics of water.

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.
