Ten different water samples were collected from Ratuwa River and its tributaries. The laboratory test was carried out by standard procedures (APHA methods), and the measured values were compared with the Nepal standard recommended by Nepal Drinking Water Quality Standards (NDWQS). Statistical analysis also had been used to calculate the correlation coefficients and to plot the regression equations of various parameters with electrical conductivity. The aim of the study was to identify the parameters that affect the electrical conductivity and evaluate the percentage contribution of these parameters. The correlation matrix shows that color, total dissolved solids (TDS), chloride (Cl), fluoride (F), total phosphorus (TP), total alkalinity (TA), calcium (Ca), magnesium (Mg), sodium (Na), and dissolved oxygen (DO) have a significant effect on the electrical conductivity (EC). Among these parameters, TDS has the highest contribution (39.65%) followed by total alkalinity (23.5%), total hardness (19.9%), chlorine (6.5%), and calcium (5.5%) ions, respectively. However, color, TP, fluoride, and DO have almost 1.45% contribution to the electrical conductivity.

Surface water samples from different locations within Tigris River's boundaries in Baghdad city have been analyzed for drinking purposes. Correlation coefficients among different parameters were determined. An attempt has been made to develop linear regression equations to predict the concentration of water quality constituents having significant correlation coefficients with electrical conductivity (EC). This study aims to find five regression models produced and validated using electrical conductivity as a predictor to predict total hardness (TH), calcium (Ca), chloride (Cl), sulfate (SO4), and total dissolved solids (TDS). The five models showed good/excellent prediction ability of the parameters mentioned above, which is a very good startup to establish a rule of thumb in the laboratories to compare between observations. The importance of linear regression equations in predicting surface water quality parameters is a method that can be applied to any other location.

Water as excellent natural resource is meant to be of good quality to prevent the outbreak of water-borne diseases. The physical, chemical and biological qualities of water constitute groundwater quality. Water of poor physicochemical quality may have adverse effects on human health and the economy. The physicochemical evaluation of fifteen borehole waters in mile 50 Abakaliki was carried out during the rainy and dry seasons to determine their suitability for drinking using standard analytical methods. During the rainy season, the temperature was 28-30°C; pH, 6.63-8.51; dissolved solids, 1.04-17.01 mg/l; total suspended solids, 0.09-0.98 mg/l; total solids, 1.14-17.99 mg/l; electrical conductivity, 107-328 us/cm; turbidity, 1.27NTU-2.60 NTU total alkalinity, 27.68-82.23 mg/l; total hardness, 70.20-150.84 mg/l; total chloride, 67.30-124.14 mg/l; calcium hardness, 24.50-53.58 mg/l; magnesium hardness, 39.40-97.26 mg/l; sulphate, 30.03-61.88 mg/l; phosphate, 0.25-6.71 mg/l; potassium, 0.00-8.04 mg/l; nitrate, 1.16-8.03 mg/l; iron, 0.00-0.26 mg/l; lead, 0.00-0.05 mg/l; cadmium, 0.00-0.04 mg/l; copper, 0.00-0.23mg/l; chromium, 0.00-0.05 mg/l and zinc, 0.07-2.15 mg/l. During the dry season the temperature was 27-29°C; pH, 6.40-7.75; electrical conductivity, 24-149 us/cm; dissolved solids, 0.10-2.03 mg/l; total suspended solids, 0.02-0.29 mg/l; total solids, 0.13-2.64 mg/l; turbidity, 0.61NTU-1.90 total alkalinity, 19.96-55.97 mg/l; total hardness, 49.61-82.35 mg/l; total chloride, 26.31-80.72 mg/l; calcium hardness, 5.63-29.30 mg/l; magnesium hardness, 30.54-67.30 mg/l; sulphate, 13.88-39.18 mg/l; phosphate, 0.07-3.18 mg/l; potassium, 0.00-4.73 mg/l; nitrate, 0.44-4.95 mg/l; iron, 0.00-0.16 mg/l; lead, 0.00-0.02 mg/l; cadmium, 0.00-0.02 mg/l ; copper, 0.00-0.15 mg/l; chromium, 0.00-0.03 mg/l and zinc, 0.02-0.64 mg/l during the dry season. From the average 7% of cadmium and 33% of lead in the water samples were above the NIS required limits of 0.003 and 0.01mg/l respectively. Generally, the water from the borehole was of poor physicochemical quality and must be treated adequately before being used by humans.

Water samples were collected from 43 sites of Tehsil Isa Khel areas in order to determine the physicochemical parameters such as pH, electrical conductivity, turbidity, total hardness, calcium hardness, magnesium hardness, M. alkalinity, chloride ion (Cl- ), and fluoride ion (F-) concentration. The obtained results show that in Tehsil Isa Khel, only in Kala Bagh city, Kala Bagh water scheme (w/s), Tola Bangi Khel w/s, Kot Chandna, Awan Wala, Gidran Wala, and Cheena Pora water is drinkable. Overall, electrical conductivity, hardness, total alkalinity, chloride, fluoride levels in the water of Tehsil Isa Khel are very high and not fit for drinking, washing, and industrial purpose. The ultimate result of this study is helpful to address the leading cause of public health problems related to the deteriorated quality of drinking water, and an integrated approach is therefore required to provide safe drinking water to people in Tehsil Isa Khel.

Samples were collected in October 2019 from two sites in the study area. Some environmental parameters measured were water temperature, pH, electrical conductivity, salinity, sulphate, total hardness, total alkalinity, nitrate and phosphate. Fifty-four species of the euglenoids belonging to six genera were encountered, one belonged to Monomorphina, two belonged to Colacium, 19 to Euglena, 10 to Trachelomonas, seven to Lepocinclis and 15 to Phacus. Thirteen species were new records in Iraq. Ten species were recorded in two sites. Most of the euglenoids found in this study occurred in Haqlan springs and were represented by 40 species in comparison to 24 species in the Euphrates river.

Rainbow Trout Oncorhynchus Mykiss

Eighteen water quality parameters (5 physical, 9 chemical, 2 climatic and 2 geographical) were investigated for the water quality assessment so as to know whether water in the raceways from spring-fed torrential stream at a high altitude was feasible and suitable for the culture of rainbow trout, Oncorhynchus mykiss (Walbaum) or not. Results indicated colourless, odourless, and crystal-clear water throughout the year with air temperature ranging from 11.4-26.9 (20.3±1.1oC), water temperature 8.4-21.5 (16±1.1oC), water velocity 1.5-3.5 (2.5±0.11m sec-1), water discharge 37-92 (56±2.87L sec-1), turbidity 3-19 (11± 1.04NTU), pH 6.5-8.2 (7.44±0.11), electrical conductivity 35-204 (112.13±11.2µS cm-1), dissolved oxygen 5.9-10.5 (8.2±0.3mg L-1), free carbon dioxide 1.4-5.1 (3.6±0.2mg L-1), total alkalinity 17-97 (55.1±5.32mg L-1), total hardness 11-90 (47±5.06mg L-1), phosphate-P 0.01-0.50 (0.14±0.02mg L-1), ammonium-N 0.09-0.91 (0.28 ±0.04mg L-1), nitrate-N 0.01-0.83 (0.17±0.04mg L-1), relative humidity 62.4-88.7 (75.01±1.59%), rainfall 0.0-503.4 (132.44±32.83mm), altitude 1550msl, and water resource stream-fed torrential stream. Correlation analyses of the parameters showed strongest correlation at the significance level of 0.01. All parameters were positively correlated except pH, electrical conductivity, dissolved oxygen, total alkalinity, and total hardness which were negatively correlated with rest. Parameters of the first year were slightly higher than second due to fluctuation in temperature, velocity and discharge, relative humidity, and rainfall influenced by climatic factors, geography, seasons, and environment of the origin and occurrence of the water resource, thus affecting rest of the parameters. Water velocity and water discharge could be maintained as per requirement of the culture. These parameters were within permissible limits being feasible and suitable for rainbow trout culture.Our Nature (2015), 13(1): 50-57
