Present investigation was carried out on Satluj river in Himachal Pradesh for the analysis of important physical and chemical water quality parameters during November, 2015 to February, 2016. Parameters such as turbidity, total alkalinity, pH, conductivity, magnesium hardness, biological oxygen demand (BOD), chemical oxygen demand (COD), dissolved carbon dioxide, total hardness, chloride, phosphate, nitrate and calciumwere analyzed from five sampling stations i.e. First Sampling Station (SS-1) – Khab, Kinnaur, Himachal Pradesh; Second Sampling Station (SS-2) – Wangtoo, Near dam site of Karcham Wangtoo Hydroelectric Plant, Kinnaur, Himachal Pradesh;Third Sampling Station (SS-3) – Bayal at the Rampur city, Shimla, Himachal Pradesh; Fourth Sampling Station (SS-4) - Kol dam, Bilaspur, Himachal Pradesh and Fifth Sampling Station (SS-5) - Wajipur Kalan, Ludhiana, Punjab in the study area. The analyses were carried out according to APHA, 2012 procedures. The analysis of data reveals that turbidity, chemical oxygen demand, biological oxygen demand and chlorides were found to be higher than the acceptable limit prescribed by Bureau of Indian standards (BIS), WHO standards. Higher values of these parameters reveal that the pollution in Satluj river is due to siltation, domestic & municipal sewage, industrial sewage and surface run-off that effect the water quality directly or indirectly.

This study based on the physicochemical parameters was conducted in order to determine the pollution status in the aquatic body of Dhaka Export Processing Zone (DEPZ) area. A total of 5 water samples were collected on the basis of their distance from the effluent outlet and were examined. Physicochemical parameters like color, temperature, pH, electric conductivity (EC), total dissolved solid (TDS), total suspended solid (TSS), total hardness, total alkalinity, dissolved oxygen (DO), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) were measured via standard determination method. Physicochemical analyses revealed that most of the water quality parameters exceeded the recommended levels set by the Department of Environment (DoE), Bangladesh. The concentrations were found decreasing with increasing distance from the effluent outlet. A very strong positive correlation was found between BOD and COD in all sampling points. Both BOD and COD values had a strong negative correlation with dissolved oxygen (DO). The results indicated that the surrounding aquatic environment is exceedingly contaminated by various pollutants released from DEPZ which is highly vulnerable for the species on that ecosystem.

Physicochemical Quality

The Bacteriological and physicochemical quality of five (5) boreholes (Ikoyi’s lodge, Newton’s Villa, Iyobosa Hostel, Embassy Hostel and Amega Villa) in Ekosodin village were investigated fortnightly, from March 2004 – July 2004. The bacteriological analysis showed low counts of total heterotrophic and potential human pathogenic bacteria that ranged from 1.0 x 101 cfu/mI – 3.1 x 101 cfu/mI, and 0.0 – 1.9 x 101 cfu/mI respectively. Total coliform counts with MPN values ranged from 0.00MPN/100mI – 9MPN/100mI. E coli occurred occasionally in stations 2, 3 and 5 with a range of 0.00MPN/100mI – 4MPN/100mI. Streptococcus faecalis was observed only in station 3, Clostridium perfringens was not detected in any of the sampled stations. Other organisms isolated and characterized during the study included Staphylococcus aureus and Proteus sp. Some of the physicochemical parameters studied included water temperature, conductivity, pH, total suspended solids, and total dissolved solids. All had low mean concentrations that ranged from 27.0ºC – 28.0ºC; 9.2 – 13.6 us/cm, 6.4 – 6.7; 0.06 – 0.08mg/l and 0.15 – 0.20mg/l respectively. The biological oxygen demand (BOD), dissolved oxygen (DO), total alkalinity and total hardness in mg/l were all low and ranged from 0.08mg/l – 0.2mg/l; 0.7mg/l – 1.0mg/l; 5.0mg/l – 6.0mg/l and 0.10mg/l – 0.13mg/l respectively. Other parameters with low concentration were nitrate (0.05 – 0.11mg/l), sulphate, (0.07mg/l – 0.13mg/l) and phosphate (0.0mg/l – 0.10mg/l). All the physicochemical parameters considered did not indicate any possible physicochemical pollution as they all fell within the (9) maximum permissible level for portable water. There were both positive and negative correlations between some of the bacteriological and physicochemical properties at a significant level of 95% probability limit. Based on the bacteriological and physicochemical parameters studied, boreholes 1 and 4 are fit for direct consumption, while bore holes 2, 3 and 5 failed to meet the bacteriological standard for portable 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.

Sand Intermittent Filtration (SIF) is an established technology of wastewater treatment and in recent years it gains renewed interest due to its simplicity and less energy requirement. The aim of the present study was to evaluate the modified filter-bed Reactor using Sand-intermittent-filtration (SIF) for the removal of physicochemical parameters viz dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total hardness (TH), calcium hardness (CaH), chloride (Cl), turbidity, total solids (TS), total dissolved solids (TDS), and total suspended solids (TSS) of the Industrial wastewater of State Industrial Development Corporation of Uttarakhand Limited (SIDCUL) at Haridwar. The experiments were performed with the composition of the filter-bed having sand and gravel in the ratio of 1:1 (Reactor I); 1:2 (Reactor II) and 2:1 (Reactor III) at the room temperature 300C. Each Reactor was categorized into A, B and C type based on depth of filter-bed (A=10 cm, B=15 cm, C=30 cm). The maximum removal of TS (52.21%), TDS (50.66%), TSS (57.20%), turbidity (67.36%), chloride (28.81%), BOD (39.18%), COD (38.66%), TH (53.40%), and CaH (62.57%) was observed in Reactor II C (soil and gravel- 2:1 and 30 cm depth of bed) using 0.49 mm effective size and 0.49 uniformity coefficient (UC) of the sand. A mixture of sand and gravel in the Reactor II with a ratio of 2:1 yielded better efficiency in comparison to the Reactor I and Reactor III. Thus, SIF technology could be environment-friendly and economically cost-effective for removing various physicochemical parameters from Industrial wastewater.

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.
