Abstract Water is a social requirement and an important factor in the ecological balance. Water from wells is good for direct consumption if the soil is not contaminated. The quality of drinking water is regulated by Law no. 458/2002 (transposing the Directive 98/83/EC on the quality of drinking water). The aim of this paper was to assess the physicochemical qualities of groundwaters from Brestea village, commune Denta, Timis County. The water samples were taken in 2015 from 10 functional wells. For the source whose physical and chemical parameters have exceeded the limit values, the monthly monitoring of the water quality (microbiological and physico-chemical properties) has been performed for 2 years. At the same time, the pH of the soil near the water sources was also measured. The results highlighted a good connection between the microorganisms from water and the nitrite, nitrate and ammonium content of water. The information can be further used to identify and eliminate the specific pollutants, areas and pollution sources.

The article presents the results of the study of the physical and chemical parameters of water for different methods of feeding the commercial young blue fox. The research was carried out at a private brewery in the Khmelnytskyi Ds. on 500 moths of the main herd. Spraying the youngsters of the experimental group was carried out in a traditional way – fom combined drinking water, distribution of water was carried out daily manually. Animals of the experimental group were injected using an automated watering system. Water samples were taken from: a water pipe, from combined drinking water for an hour and 12 hours after hand delivery – in the control group, from self-steering racks for maintenance of fur animals – in the experimental group. An analysis of the dynamics of physical and chemical parameters of water (odor, color, turbidity, rigidity, active acidity, dry residue and chlorides) was carried out for different methods of watering, and compliance with their current norms for drinking water for farm animals was established. In the course of experimental studies, there were significant differences in the organoleptic parameters and water properties in the control group as compared to water samples. Thus, for manual distribution of water for 12 hour there was a deterioration of odor on 1.1 points, increase turbidity almost twice, decrease in acidity – by 1.06 units. The indicated indicators exceeded the maximum permissible norms. The reasons for violations of the quality of drinking water in the traditional way of drinking were: contact with feed mixes in combined drillers, the effect of abiotic and biotic factors, staining residues. In samples of water in the experimental group there were no significant deviations of physical and chemical indices: they were within the limits of permissible norms. Isolation of drinking water from the environment, dosing at the need of the animal proved to be the main advantages of the atomized method of drinking fur-bearing animals, which gives grounds to recommend it for introduction into production. Further scientific research will focus on the study of the microbiological characteristics of water for different ways of drinking fur-bearing animals and, in fact, blue fox. In addition, interesting from a practical point of view can be the study of productive indicators of commodity young animals of fur animals with different methods of watering. It should take into account not only the dynamics of animal growth, the quality of fur, the level of preservation, but also production costs, including changes in the structure of the cost of fur.

Water is the most abundant and non-renewable resource in the earth, which play an important role in all living organisms. A study on physiochemical parameters of Manur, Vallanadu and Sundarapandiapatinam ponds from Tirunelveli, Thootukudi and Ramanathapuram districts of Tamil Nadu, India, has addressed the seasonal changes. During the month of January to April samples from Manur was chemically portable, Vallanadu sample was physically portable, Sundarapandiapatinam samples were physically and chemically not portable. During the month of May to August Vallanadu and Manur samples were portable by its physical and chemical examination, Sundarapandiapatinam samples were non portable by its physiochemical property. September to December the samples from all the three ponds were non portable because of exceeding the permissible limit. All the samples were bacteriologically unsafe in nature because of its microbial contamination. This implies the water bodies are not fit for domestic and drinking purpose, thus proper management has to be done by the society and implement government guidelines to save the natural resources from manmade activities.

Sensory quality of peach during ripening to assess the best state for consumption was analysed. Physical and chemical parameters commonly used for establishing the commercial quality of this fruit were also determined: Soluble solids, acidity, sugars, organic acids, chlorophyll, carotenoids, resistance to compression and to penetration and colour. Relationships among these parameters and sensory characteristics were also analysed. A panel of eight trained assessors evaluated intensities of 12 sensory attributes (1 for odour, 2 for colour, 4 for flavour and 5 for texture). The sensory attributes selected allowed the description of perceivable differences between peaches of different degrees of maturity, although the variation in intensity of the attributes followed different trends. Colour intensity increased and acidity, firmness and crispness decreased significantly with ripening. Intensity of flavour, sweetness and fruitiness increased significantly from the under-ripe to semi-ripe states, and then decreased on reaching ripeness. It can be concluded that the most suitable time for harvesting and consumption of this peach variety was the state described herein as semi-ripe, and that a high correlation existed between colour intensity and hardness and the instrumental measurements of colour and texture.

Traditional modern chemical technology methods for solution and liquid mixture component separation are based on the difference between physical and chemical parameters of components being separated (boiling point, solubility). The methods use the phenomenon of phase change. Thus to install the equipment for the processes is quite complicated and power-consuming.As the world population grows we face new problems,i.e. the shortage of drinking water. Different methods are applied for getting drinking water such as distillation and freezing out. Half of all the desalinated water is got by distillation. To solve the arisen problems by using the traditional methods of chemical technology is becoming more and more complicated. Methods of membrane separation have turned out to be promising in this respect.
