Abstract

The alkaline Lonar crater, located in the Buldhana district of Maharashtra, India, is the only hypervelocitymeteoritic impact crater in basalt rock, ranking third in the world and best preserved impact structures on the earth. The uniqueness of this crater is that it has been formed in strata of hard igneous, basalt rocks. Due to uniqueness and its large size, it has become one of the important craters in the world. The Lonar lake is natural for the accumulation and concentration of saline constituent in the lake water. An attempt has been made to study and compare the information of physicochemical qualities of Lonar lake water. A total of 36 water samples were analysed in 2008 for physicochemical qualities of Lonar lake water. These findings revealed that the Lonar lake water was alkaline (pH 10.3) and characterized by high concentration of salts (9060 mg/L), chloride (3492 mg/L), salinity (6391 mg/L), alkalinity (3751 mg/L), total hardness (480 mg/L), calcium hardness (118 mg/L), magnesium hardness (361 mg/L), sulphate (21 mg/L), phosphate (0. 44 mg/L), nitrate (3.7 mg/L) and dissolved oxygen (0.0034mg/L). The Lonar lake is unique in theworld for its alkalinity and salinity of thewater but it is seen that chlorides and salinity of the lake water is decreasing day by day. Hence, it should be protected and preserved for its uniqueness and a scientific phenomenon as a national treasure.

Abstract

Water Quality Index (WQI) based on physicochemical quality of the water of Purna river basin in Akola and Buldhana district of Vidarbha region was carried out during August to November 2007. A total of 260 water samples were analysed for various physical and chemical parameters. The study showed that all water samples were within the standard permissible limit prescribed by WHO and ISI standards for drinking water except salinity, chloride, nitrate, phosphate and conductivity. On the basis of CCME Water Quality Index (WQI) derived from physicochemical studies, the drinking water was 80% safe and 20% unsafe for the drinking and domestic purposes in salinity-affected villages of Vidarbha region.

Abstract

Pseudomonas aeruginosa is a common organism found in water and its growth can cause problems with color, taste, odour and turbidity of the drinking water. In the present study, a total of 210 water samples were analysed and 40 strains of Pseudomonas aeruginosa were isolated and identified from various drinking water sources from different localities in Amravati city. Antimicrobial susceptibility tests were carried with 24 antibiotics, which showed 47% resistance, and 53% sensitive.The studies reported high incidence (30%) of Pseudomonas aeruginosa in drinking water showing danger to human health due to its biofilm producing ability and indicating emergence of antibiotic resistance due to the indiscriminate use of antibiotics.

Abstract

Waterborne infections are most common cause of mortality in underdeveloped and developing countries, and 80% of the infectious diseases are waterborne in India. There is problem of multiple drug resistant in Salmonella typhi in drinking water due to improper and indiscriminate use of antibiotics in the treatment. Therefore, attempt was made to isolate Salmonella typhi from different sources of drinking water and to find out its antibiotic sensitivity to prescribe correct treatment to the typhoid patients in Amravati. A total of 1000 water samples from various sources such as tube wells (340), open wells (340) and hotels and restaurants (320) were analyzed for the coliform water contamination and 96 strains of Salmonella typhi were isolated and observed. Most of the strains of Salmonella species were sensitive to norfloxacin; ciprofloxacin, levofloxacin, kanamycin, streptomyvcin, ceflazidime and chloramphenicol, and resistant to linezolid, gatifloxacin, amoxyclav, cefepime, ampicillin, nalidixic acid and co-trimoxazole.

Abstract

The physico-Chemical quality of drinking water is totally depend on the geological condition of the soil and ground water pollution of the area. In the present study water quality index of open well waters was 73.49 and for tube well waters 73.01 showing fair quality of ground water, indicating that the water quality was protected but occasionally threatened or impaired.
