Human beings require potable water for drinking to keep them healthy. Clean, safe and adequate fresh water is vital to the survival of all living organisms. Drinking water affects the health of human beings due to the presence of various dissolved chemical constituents. Problems arising out of chemical constituents in drinking water are different from the problems of microbial contamination. Therefore, consumers should have at least minimum knowledge on quality of drinking water. People across the world depend on ground water for drinking. Ground water is a major source, so based on the importance of the matter; a research topic is taken up on the assessment of quality of groundwater in the selected areas of villages in Veeraghattam and Palakonda Mandals of Srikakulam District, Andhra Pradesh. This preliminary study assessed the quality of physical and chemical characteristic properties of underground water in the selected locations of 40 villages in Veeraghattam and 39 villages in Palakonda Mandals of Srikakulam District. Some physico chemical characteristic parameters are estimated in the samples and the results obtained are compared with the available standard values such as WHO and BIS.

Water quality information is needed to assess the state of water contamination in a variety of community, including those that rely primarily on unimproved underground sources of drinking water. The study was carried out with an aim to assess the quality of ground water in particular sites of the Kathmandu valley. The ground water samples were collected from shallow well, tube well and deep tube wells located at specific places of the valley. The research was focused on physiochemical and bacteriological analysis of underground water from sites near to Bagmati river (≤20 meters) and from sites far from Bagmati river (>50 meters). The sampling sites were scattered from Sinamangal to Minbhavan. Total sample size was 100, with 50 in each stratum. Study processing was done during the period from February 2013 to May 2013. Six physiochemical parameters namely pH, Conductivity, Ammonia level, Chloride level, Nitrite level, Nitrate level and Biological parameters (Coliform and Fecal coliform) of each sample was tested. Based on the research work, it was recorded that the underground water close to river (≤20 meters) has comparatively high physiochemical and biological parameter (Fecal Coliform) than underground water that were farther from the river (>50 meters). Fecal Coliform was predominant 58% (29/50) in water nearer to river rather than in water farther from the river 20% i.e. (10/50).  Similarly, the values of physiochemical and biological parameter increased comparatively with more distance i.e. ≤10 meters from river. The finding indicated that the underground water near to river is more polluted than far from the river.Nepal Journal of Biotechnology. Dec. 2017 Vol. 5, No. 1:21-26

The results of studies of physicochemical composition of drinking water and the magnitude of its Zeta potential establishing the degree of dependency of these indicators. Samples were taken in winter and summer. It is shown that variation of values for such parameters as alkalinity, hardness, contents of Ca2+ and Mg2+ slightly on the individual areas of sampling. It is established that values of indic ators of quality of drinking water from underground water intakes was more stable than from a surface source. In artesian water values the Zeta potential (ζ-potential) was 3-7 times lower than in the Volga. The alkalinity of the water year was slightly above winter. There were relations between the value of the Zeta potential and alkalinity of the water as well as turbidity and hardness. In most cases, the magnitude of the accuracy of the approximation was greater than 0.9.

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.

Atrazine, a chlorinated s-triazine group of herbicide is one of the most widely used pesticides in the World. Due to its extensive use, long half-life and various toxic properties, it has very high environmental significance. Up to 22 mg l-1 of atrazine was found in ground water whereas permissible limit of atrazine is in ppb level in drinking water. As per Indian standard there should not be any pesticide present in drinking water. Among many other treatment processes available, Incineration, adsorption, chemical treatment, phytoremediation and biodegradation are the most commonly used ones. Biological degradation of atrazine depends upon various factors like the operating environment, external carbon and nitrogen sources, carbon/ nitrogen ratio (C/N), water content and the bacterial strain. Although, general atrazine degradation pathways are available, the specific pathways in specific conditions are not yet clearly defined. In this paper extensive review has been made on the occurrence of atrazine in surface and ground water bodies, probable sources and causes of its occurrence in water environment, the toxicity of atrazine on various living organisms and its removal by biological processes.

The physical and chemical characteristics of the fruit have immense significance as they ultimately affect the quality of processed productsprepared from them. Over ripening of Sapota (Manilkara zapota) fruits at the post-harvest stage usually results in dramatic decline in quality.In the present study, physico chemical analysis (which includes Weight loss, Colour, Texture, TSS, pH, TA and Ascorbic acid content) ofedible Aloe vera gel coated Sapota fruits packed in LDPE and stored at 15 ± 2? were studied at regular intervals of 5 days i.e., 0th,5th, 10th,15thand 20th days. The dip treatment of Aloe vera gel coating 1:2, 7 minutes had best retained the physico chemical characteristics than the othertreatments performed and was found to be the most effective treatment in maintaining the fruit quality attributes along with the shelf lifeextension of about 20 days.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11703 Int J Appl Sci Biotechnol, Vol. 3(1): 20-25

Quality cassava(Manihotesculentus, Crantz) flour is often influenced by process variables such as slice weight and soaking time which may affect its nutritional quality. In this study, the effect of process variables (slice weight and soaking time) on quality of cassava flour was carried out. Cassava root was peeled, washed and cut into varied sizes (25.86 - 54.14 g) and soaked at varied time (7.03 - 40.97 h). The proximate composition, physical and chemical properties of the flour were carried out using standard methods. The result in our findings showed that slice weight and soaking time had significant increase (p<0.05) on the proximate and physico-chemical properties of the flour.The amylose and amylopectin content of the flour increased with increasing soaking time while the hydrogen cyanide content decreased with increase in soaking time. Overall, the quality cassava flour displayed desirable properties for its incorporation into baked goods.

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.
