Growth and survival of Clarias gariepinus in different water qualities were investigated. Initially, water of equal quality was used for the experiment, later the quality of water varies due to period of water change, (daily-T4, weekly-T3, bi-weekly-T2 and monthly-T1). Physico-chemical parameters were analyzed. Two hundred and forty (240) seven weeks old fingerlings of C. gariepinus were randomly distributed into 12 plastic tanks. Poor growth of C. gariepinus was observed in the treatment tanks (T1, T2 and T3), compared with growth of fish in the control (T4) which was progressive as indicated by the higher value of condition factor. Treatment tanks had significantly (P < 0.05) higher EC, TDS, Turbidity, Ammonia, Nitrate and Nitrite and significantly (P < 0.05) lower DO than culture water in control container. Slight growth was recorded for fish in T1 and T2 until the second week when drop in fish weight was observed. This study has shown that poor water quality can reduce growth rate and survival of C. gariepinus.

The aim of the paper is to evaluate the quality of water of the Mantovo Reservoir (Southeast Macedonia)based on physico-chemical parameters and the macrozoobenthos. Monthly sampling was performed during 2003 and 2004. Temperature and DO depth profile data indicate that the Mantovo Reservoir is a dimictic lake. Based on mean nutrient concentrations, the Mantovo Reservoir can be considered as being phosphorus-deficient. During the summer stratification, very high concentrations of Mn (2,819 ?g/l)and Cu (147.6?g/l)were detected in the lower profundal. Limnodrilus hoffmeisteri was the dominant species, which indicates the presence of organic pollution. Dominance of Chaoborus crystallinus and decline in abundance of L. hoffmeisteri in the lower profundal indicate a deterioration of environmental status in the deepest part of the lake.

In a bid to ascertain the quality of water for human consumption in Kashere Metropolis, essential physico-chemical parameters were evaluated on samples of drinking water obtained from boreholes, pond and wells located at densely populated areas, labelled as: Kashere cattle market Pond, KP; Kashere cottage Hospital Borehole, HB; Kashere Market Borehole, MB; Federal University, Kashere (FUK) campus Borehole, CB; Kashere cottage Hospital Well, HW; Kashere Market Well, MW and FUK campus Well, CW. Standard procedure for the determination of chemical and physical characteristics of the water samples were used. The results of the investigated parameters in the samples were as follows: ρH 6.61‒7.96, Turbidity 0.0‒2568 FTU, Electrical Conductivity 60.5‒1151 Mhocm-1, Total Dissolved Solids (TDS) 25.9‒518.0 mgL-1, Ca 0.0033‒0.5446 ppm, Mg 0.0793‒1.2215 ppm, Cd 0.0010‒0.0030 ppm, Zn 0.0024‒0.l054 ppm, Pb 0.0002‒0.0026 ppm and Fe 0.0044‒0.5649 ppm. Except for the concentration of Fe (in CB; 0.5649 ppm), all the analyzed minor and major cations in the water samples were in very low concentration and below the permissible limits of WHO standard guidelines values for drinking water.  It is recommended that, water from the pond should be properly treated before consumption due to its high turbidity.  Also periodic assessment of the quality of drinking water from these water sources should be conducted, to ascertain that they are not contaminated by either or both organic and inorganic pollutants.

Reconstituted Milk

Milk and dairy products play an important role in human diet due to their high nutritional and biological value, as well as to their easy digestibility. Milk powder makes it possible to improve the seasonal character of dairy foods. As a solvent in the production of reconstituted milk, water can significantly affect the quality of the finished product. In this regard, the problem of water quality and its preparation for the production of reconstituted milk is highly relevant. The method of separate freezing allows one to reduce the number of pre-treatment stages and energy costs. The research objectives were 1) to establish the effect of separate freezing on water quality indicators, 2) to determine the solubility index of milk powder in water prepared by the method in question, 3) to definethe energy costs. The research was carried out on the basis of the Department of Heat, Ventilation, and Air Conditioning Equipment (Kemerovo State University). The study was conducted with the help of a tank crystallizer with a controlling and measuring complex for registration of temperatures at temperatures from minus 2 to minus 10 C. In defining the quality of water and reconstituted milk, the authors used standard methods for determining its organoleptic and physico-chemical parameters. The study made it possible to define the organoleptic and physico-chemical parameters of water before and after separate freezing, the solubility index of dry milk, and the quality of reconstituted milk obtained by the method. The research revealed that it is energetically more advantageous to carry out the procedure at the temperature of minus 2 C. The present paper describes the numerous advantages of the method in that it reduces: 1) the dry residue content in tap water by 8 times, 2) the overall hardness of water by 2.5 times, 3) the content of chlorides and fluorides by 1.7 and 1.9 times, respectively, 4) the solubility index of milk powder from 0.35 to 0.1 cm3. All these factors improve the quality of reconstituted milk.

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.

Limestone Rock

The goal behind this work is defined as the study of the quality of water from karst springs near quarries exploiting limestone rock in order to assess its adequacy with domestic uses. At that end, a study at the mountain level was carried out. This mountain is in the Haouz area, in Tetouan, which is located north of Morocco and shelters active quarries. This research is based on the assessment of the physico-chemical parameters of the spring water used by local residents and located near this industry. The water quality evaluation was carried out by comparing the recorded values, according to Moroccan Standards related to the quality of water for human use. The review of some parameter’s indicative of water pollution (T °, pH, electrical conductivity, dissolved oxygen, turbidity, total dissolved solids and the alkalimetric total title) revealed that the quality of the studied spring water is good and does not present any health risk to the users of this water during the winter season.
