The hydro geochemical features of Neyyar River for a period of one year from May 2015 to April 2016 were analyzed. Six sampling sites were fixed considering physiography and present landuse pattern of the river basin. The residents in the drainage basin are primarily responsible for framing a better landuse and thereby maintain a good water and sediment regime. Geospatial pattern of the present landuse of the study area indicated that the sustainability of this river ecosystem is in danger due to unscientific landuse practices, which is reflected in the river quality as well. The parameters such as hydrogen ion concentration, electrical conductivity, chloride, Biological Oxygen Demand, total hardness and sulphate of river water and Organic Carbon of river bed sediments were analyzed in this study. The overall analysis shows that the highland areas are characterized by better quality of water together with low organic carbon, which is mainly due to better landuse and minimal reclamation. The midland and lowland areas are characterized by poor quality of water with high organic carbon, which is due to high anthropogenic activities and maximum pollutants associated with the region together with the alteration in landuse from a traditional eco-friendly pattern to a severely polluted current pattern.

Water plays a key role in the survival, growth and reproduction of aquatic organisms. Therefore maintaining good quality of water physico-chemical parameters would ensure optimum productivity of aquatic fauna. The study evaluated water physical and chemical parameters (temperature, hydrogen ion concentration (pH), conductivity, dissolved oxygen (DO) and biochemical oxygen demand (BOD) of Bodo Creek. Sample was collected for 5 months (July 2020 – November 2020) at locations previously studied (before-spill baseline studies, 3 years, 5 years, and 7 years after-spill); by using the sampling methods used in previous studies. Spatially, there was no statistically significant difference in temperature (p > 0.05 = 0.997), pH (p > 0.05 = 0.496), DO (p > 0.05= 0.34) and BOD (p > 0.05 = 0.644). However, the difference in conductivity between the stations was statistically significant (p < 0.05 = 0.006). On monthly basis, there was a significant difference in temperature (p < 0.05 = 0.000) and pH (p < 0.05 = 0.005). In contrast, there was no statistically significant difference in conductivity (p > 0.05 = 0.633), DO (p > 0.05 = 0.559) and BOD (p > 0.05 = 0.75). Most of the physico-chemical parameters were not within the WHO recommended levels for the survival of aquatic lives, indicating a high level of environmental pollution in Bodo Creek. This study provides dataset for future evaluation of the water physico-chemistry of Bodo Creek.

Water is one of the most important natural resources which play an essential role in human life. Most of the Nigerian institutions stored water in either plastic or overhead tanks for different purposes. However, there has been a growing concern over the safety of the stored water for human consumption following reported cases of microbial occurrence in water stored in tanks. This study aimed at investigating the water quality stored in plastic tanks in Umaru Musa Yar’adua University Katsina. Water samples were collected from plastic tanks and analyzed for some physico-chemical and heavy metals parameters. The result of physico-chemical parameters obtained shows that only dissolved oxygen, biological oxygen demand and chemical oxygen demand were observed above the maximum permissible limit for drinking recommended by WHO and NSDWQ with the mean value of 55.18 mg/l, 38.86 mg/l and 38.08 mg/l respectively. While the remaining parameters such as pH, electrical conductivity, total dissolved solids, turbidity, total suspended solid, alkalinity, sulphate, nitrate, phosphate, chloride and total hardness were found within the acceptable limit. However, analyzed result of heavy metals parameters revealed that all parameters were observed within desirable limit by WHO and NSDWQ for drinking water and suggested that the quality of water stored in plastic tanks was very good. It is concluded that, the quality of water stored in plastic tanks is suitable for human consumption. It is therefore recommended that, continuous monitoring of the water should be maintain so as to ascertain the safety of the water

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.

Lake Water Quality

A 3-year study was conducted by the U.S. Army Corps of Engineers assessing water quality related impacts of aquaculture of 250,000 channel catfish (Ictalurus punctatus) in floating net pens in the Rock Creek Arm of Lake Texoma, Oklahoma/Texas. Five large nylon nets suspended from a floating framework of galvanized metal anchored in open water 100 m offshore made up the net pens with fish stocking densities varying from 88 to 219 fish/m3. Water quality sampling was conducted biweekly from April to September and monthly from October to March at three locations. On all sampling dates field measurements of water temperature, pH, dissolved oxygen, and conductivity were recorded at 1 m depth intervals and water samples were collected at a depth of 0.5 m and near the bottom of the water column at each site. Sample analyses included: total alkalinity, total hardness, turbidity, chloride, sulfate, orthophosphate, total phosphorus, nitrate-N, nitrite-N, total Kjeldahl nitrogen, total organic carbon, dissolved organic carbon, biochemical oxygen demand, and chlorophyll a. The results showed statistically significant decreases in water temperature and dissolved oxygen and significant increases in field conductivity in surface waters near the net pens relative to other sampling sites. The most dramatic water quality effect observed during the study was decrease in dissolved oxygen levels near the net pens following lake turnover in the second year.

Quality Of Water

The urbanization process through which large urban centers have been passing has drastically affected the availability and especially the quality of water. The Cachoeirinha Invernada Watershed (CIW), located in the municipality of Guarulhos (State of São Paulo, Brazil), includes areas with different land use classes. This paper aims to correlate the spatial and temporal effects of land use and land cover on the water quality of the Cachoeirinha Invernada Watershed. In a period of 12 months and at six sampling points along the watershed, the physicochemical parameters temperature (T), pH, turbidity (TU), total solids (TS), electrical conductivity (EC), total phosphorus (TP), biochemical oxygen demand (BOD), as well as microbiological analysis (E. coli) were measured. Water quality was assessed using a modified version (WQIM) of the Water Quality Index (WQI) and the Trophic State Index (TSI). The areas surrounded by urban development presented a marked worsening in water quality, with the downstream point most affected and ranked as ‘POOR’. From the evaluated parameters, what contributed most to water quality degradation of the Cachoeirinha Invernada Watershed (CIW) was E. coli, followed by BOD, and TP, all parameters related to the presence of sewage in the water. The need for the construction of sewerage and waste treatment, protection and recovery of riparian forests, and environmental education regarding waste disposal are necessary to significantly improve the environmental quality of the Cachoeirinha Invernada Watershed.
