STUDY OF PHYSICO-CHEMICAL PROPERTIES AND THEIR CORRELATION STUDY OF DRINKING WATER FROM BORE WELLS OF DIGRAS TALUKA REGION, DIST.- YAVATMAL (M.S.) INDIA.

An investigation on the bacteriological and physico-chemical properties of stored household drinking water in Ado-Ekiti, Nigeria was carried out between April and October, 2008. The drinking water sources considered for examination were harvested rain water, tap water and well water stored in plastic water pots for 2 to 4 days. The waterborne pathogens in the samples that were isolated were characterized for antibiotic resistance. Estimation of bacterial loads in the water samples revealed mean total bacterial count (TBC) of 1.17 × 105, 1.30 × 104 and 9.70 × 104 cfu/ml for rain water, tap water and well water respectively. The mean-total coliform count (TCC) were recorded as 1.57 × 106, 7.40 × 105 and 5.70 × 105 cfu/ml for rain water, tap water and well water respectively. Seven bacteria genera comprising Escherichia (41.7%), Shigella (75%), Klebsiella (33.3%), Pseudomonas (25%), Staphylococcus (25%), Streptococcus (50%) and Enterococcus (20%) were isolated from stored rain water .Three genera comprising Escherichia coli (8.3%), Staphylococcus (25%) and Pseudomonas (75%) were isolated from stored tap water. In well water samples, nine genera comprising Escherichia (50%), Salmonella (100%) Enterococcus (80%) and Shigella (25%) Proteus (100%) Serratia (100%), Klebsiella (66.6%), Staphylococcus (50%) and Streptococcus (50%) were isolated. The antibiotic susceptibility tests showed that the majority of the bacteria isolated particulaly, Escherichia, Salmonella, Enterococcus and Shigella were resistant to common antibiotics which are still available in Nigerian market. The resistance pattern of the bacterial isolates ranged from 50–100% to amoxicillin, tetracycline, streptomycin, cotrimoxazone, erythromycin, gentamicin. In terms of physico-chemical analysis, all the water samples met the WHO standard for drinking water. However, the results obtained revealed that adequate domestic water sanitation and disinfection programmes must be put in place to ensure safety against waterborne antibiotic resistant pathogens especially in developing countries.

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.

Purification Of Water

Abstract The objective of this study was to examine the microbiological and physico-chemical properties of different types of drinking water used. The cross-sectional type study was carried out between January 1 and April 30, 2016. The samples acquired for the study from 50 packages, 50 tap water taps, and 50 residential treatment devices were examined both microbiologically and biochemically. The pH values varied between 5.57 and 8.26. pH values of tap and packaged waters were all determined to be proper, and improperly low pH values were determined in 25 of the samples acquired from the residential treatment devices. It was determined that amounts of fluoride, chloride, nitrate, nitrite, arsenic, and ammonium were all acceptable. Fluoride amounts were determined to be high at a statistically significant level in packaged and residential treatment device water (p = 0.000). Escherichia coli was determined in 10% of tap water and 2% of packaged water. Microbiological contaminations of the samples collected after the pump-faucet and water fountain were determined to be greater in comparison with those of samples collected directly from packaged waters. It was determined that the residential treatment process is applied more on drinkable waters. The purification of water causes significant physico-chemical changes.
