Physico Chemical

A physico chemical and microbiological study of the ground water of some villages of Surat district of Gujarat state (India) has been made. Physico chemical parameters such as colour, odour, taste, temperature, pH, electrical conductivity, TS, TDS, total hardness, total alkalinity, calcium, magnesium, iron, sodium, potassium, chloride, sulphate, nitrate, fluoride and silica were determined. In microbiological study, total coliforms, E. coli, sulfate reducing anaerobic bacteria, pseudomonas aeruginosa, yeast and mould were investigated. Samples were taken from ten sampling points in ten different villages viz. Parvat(S-1), Kharvasa(S-2), Bonand(S-3), Vesu(S-4) Amroli(S-5), Kadodara(S-6), Chalthan(S-7), Variyav(S-8), Gaviyar(S-9) and Bhairav(S-10). Samples were taken four times in year in the month of May, August, November and February to check the seasonal effects. In village Gaviyar, Gujarat Water Supply and Sewerage Board has set up a treatment plant to supply good quality potable water in few surrounding coastal villages. In all other cases samples were taken from bore-well. Here study reported is for samples taken in May-2004 and August-2004.For colour, iron, sulphate, nitrate, fluoride and silica, instrumental methods like spectrophotometry were used. “Hach-Odyssey spectrophotometer” which has facility to store calibration curves and which can display the value for that parameter directly was used. In present study programmes of “Hach” with their reagents were used while some programmes were prepared by us using our reagents. This is an excellent instrument and results of this instrument are validated by USEPA. Sodium and potassium was determined using flame photometer. It was found that some water samples have higher TDS, chlorides, total hardness and total alkalinity than the permissible limits. In all cases samples were not found to contain significant quantities of bacteria and water was palatable from this point of view.

Riverine Systems

Healthy riverine systems provide ecological services that can be translated into human use and consumption. However, human activities cause environmental degradation limiting available pristine water supply and raising public health concerns. In the present study, four tributaries surrounding Mt. Matutum Protected Landscape (MMPL) were selected (Glandang, Linan, Kawit, and Amlok) for evaluation of their physicochemical and microbial characteristics between wet and dry season. The pH and total dissolved solids (TDS) of the river waters ranged from 6.75-8.68 and 55.96-221.89 ppm, respectively, with a pronounced pH fluctuation and TDS increase in Glandang and Linan tributaries from upstream to downstream stations. All tributaries showed varying dissolved oxygen (DO) levels upstream but become relatively stable downstream. All DO values, however, are below the standard limit set for freshwater quality. In terms of microbial load, total coliform ranged from 51-275 cfu/ml while E. coli showed absence (0 cfu/ml) to as high as 77 cfu/ml. Higher total coliform counts were observed on Kawit and Amlok tributaries which are situated in areas that are relatively more forested than the other two rivers. Presence of E. coli was also detected in the water samples from all tributaries. Temporal variation is significant indicating increased pH, TDS and microbial load during the wet season and DO during the dry season. The present microbial load of the four tributaries would restrict the utilization of water resource and necessitate proper treatments prior to domestic use. Read full article here.

Potable Water Quality

The multivariate statistics analysis was used to analyze the correlations between 24 physical and chemical parameters values, for raw and potable water quality characterization, using data collected monthly from a potable water preparation plant during two years, 2015 and 2016. The t-Test (Student) and the Principal Component Analysis were used in order to analyze if there are tight dependences between the analyzed parameters, allowing eventually to purpose the analysis scheme schedule modification.

A potable water survey, in two important municipalities of the state of Sinaloa, Mexico was conducted. Culiacan, capital city of Sinaloa and its neighboring municipality, Navolato were selected to enumerate Aeromonas hydrophila, Escherichia coli, fecal and total coliforms, Pseudomonas aeruginosa, and Heterotrophic plate count bacteria from 100 households' taps. Manganese; residual chlorine; pH; temperature and turbidity were also examined. Overall, Aeromonas hydrophila was not detected in any of the samples, 3% contained Escherichia coli, 28% had fecal and 46 total coliforms, P. aeruginosa was present in 15% of the samples. HPC bacteria were found in all of the samples but 43% had numbers greater than 500 CFU per ml. The average numbers obtained for the physico-chemical parameters were 0.15 mg/L; 0.32 mg/L; 6.5; 28.7°C and 2.92 NTU for manganese, residual chlorine, pH, temperature and turbidity, respectively. The findings of the current study demonstrate that potable water from both municipalities can harbor substantial numbers of indicator and opportunistic pathogens suggesting that additional treatment in the household may be needed.
