The open well drinking soft water sources are completely become dry or they get salt water due to the influence of sea water near the coastal belt. The present study is based on the analysis of spring water sources at Ramathirtha of Gokarna situated in India for its quality with respect to potable drinking water. In recent years many countries have started use of spring water as the source drinking water as they have a quality almost equals to specification given for drinking water [1]. The spring water at its origin doesn‟t contain any pollutants and it is to be considered as mineral water or the bottled water as it contains essential minerals from the rock beds. The specification for the drinking water quality in India has given by IS 10500:2012, CPCB classification of Water and WHO guidelines are considered here to classify the spring water quality. Physico-chemical parameters like pH, Turbidity, Conductivity, Sulphates, Hardness, Total alkalinity, Nitrates, Chloride, DO, BOD, TDS, TSS and Microbiological parameters are measured in this study reveals that suitability of spring water for drinking purpose and has a good content of minerals. Both the spring water and open well water samples at the time of midsummer were collected for comparing the quality of drinking water. This case study was undertaken in the month of April-May of three consecutive years and the water quality is found be belongs to Class „A‟ of Drinking water. Hence, it has been suggested that spring water source can be used as a source of drinking water at coastal area and it may be considered as a permanent source of natural mineral water in near future at the coastal belt of Karnataka.

Lakes are not part of the ocean but it lie on land and therefore they are distinct from lagoons. Lakes are an important water resource found on this planet. Lake water is source for drinking and many of the domestic use in rural and urban population of India. The main aim of current study was to assess water quality of kotiteertha lake, Gokarna a holy place situated in Karnataka. Water samples were collected in winter season of Costal Karnataka. Due to increased population and manmade activities and performing rituals, water is being highly polluted with different types of contaminates 1. The water samples were collected at five different selected sampling sites. The assessment of physico chemical parameters of Kotiteertha lake water was done during January 2018.It is very necessary to know details about different parameters like pH , temperature, turbidity , alkalinity, hardness, conductivity, sulphate, TS,TDS,TSS, DO,BOD etc. At the end of the results obtained from different physic-chemical parameters we came to know that Kotithirta lake has been declared as class E types of lake according to classification laid by CPCB. The lake water is not suitable for drinking purpose as per criteria laid down by the IS 10500:2012 without filtration or necessary pre treatments.

These copper complexes were characterized using analytical techniques such as elemental analyses (CHN), spectral analyses (FTIR, 1 HNMR and ESR) and physicochemical studies (molar conductance and magnetic moment). FTIR spectra demonstrated coordination mode for the Schiff base ligand that behaves as tetradentate with Cu 2+ ions. The elemental analysis by magnetic studies and ESR spectra suggested the distorted square-planar geometry for these complexes. Further, ESR spectra of the crystalline Cu (II) complexes showed covalent nature for the metal ligand bond. The molar conductance in dimethylformamide solution indicated that all complexes are non-electrolytes. Furthermore, these compounds were tested for their therapeutic potentials, using rat and mouse models. The Cu (II) complexes with pyridinimine-based Schiff base

UV–vis spectrophotometer, XRD, FT-IR, FESEM/TEM, TGA and EDAX analysis were used to characterize the obtained NPs. The formation of NPs is evident from their surface plasmon resonance peak observed at �max = ∼550, 450 and 500 nm for Au, Ag and Au–Ag alloy NPs respectively. XRD pattern revealed that fcc structure, while FT–IR spectra signify the presence of phytochemicals adsorbed on NPs. Such a biofunctionalized NPs were characterized by their weight loss, 30% due to thermal degradation of plant phytochemicals observed in TG analysis. The spherical shape of Au, Ag and Au–Ag alloy NPs (∼10–50 nm) is observed by FE-SEM/TEM images. EDAX analysis confirms the expected elemental composition. Moreover, these NPs showed enhanced antimicrobial, antioxidant, and anticancer activities, though it is more pronounced for Au–Ag alloy NPs, which is due to the combining effect of phytochemicals, Au and Ag metals. Thus, the biosynthesized NPs could be applied as effective growth inhibitors for various biomedical applications.
