An attempt has been made to study the Physico-chemical condition of water of Yamuna River at Gokul Barrage, Mathura, (UP). The time period of study was July 2015 to June 2016. Three water samples were selected from different sites in each month for study. The parameters studied were Temperature, Turbidity, pH, DO, BOD, COD, Total Dissolved Solids and Suspended Solids. Almost all the parameters were found above the tolerance limit.

Research was held in the estuary of the river Bach Dang (Dongbay community, Rakhtay district, Hai Phong, Vietnam) in June, 2012 - May, 2013. Concentration of lead was studied in water, suspended solids and bottom sediment. Clam beach (natural breeding environment of Meretrix lyrata ) was inspected regularly, every month. Water samples were taken 6 times from the bottom layer 10 cm down the bottom, once per 3 hours in each of 12 investigated zones. Bottom sediment samples were taken at the depth 2 cm. The findings show that lead accumulates mainly in suspended solids (23.3 mg/kg) and in bottom sediment (14.31 mg/kg), in water it is in small quantities (0.003 mg/kg). Analysis of bottom sediment samples taken in different places showed that they have even leadcontent, lead is distributed uniformly, localization of contaminations is not found. The results obtained can be assumed as the basis for investigating lead accumulation and its excretion by clam Meretrix lyrata organisms in the natural habitat.

Abstract The concentration distribution of hexachlorobutadiene (HCBD), pentachloro-benzene (QCB), hexachlorobenzene (HCB) and octachlorostyrene (OCS) in water samples from transects across the upper and lower St. Clair River and the upper Detroit River were determined on four occasions in 1985. The data show a plume of these contaminants from the Sarnia industrial area. The fluxes and concentration profiles of the contaminants at Port Lambton have been modelled success fully using a simple transverse mixing model. A study on the chemical partitioning between the “dissolved” and “suspended sediment” phases shows that an important contaminant fraction is carried in the river by the suspended solids, particularly for lipophilie compounds such as HCB and OCS,

Three seasonal surveys of suspended solids were carried out in an on-stream stormwater management pond, by means of a submersible laser particle size analyser. Size distributions were measured at up to 17 points in the pond, and water samples collected at the same locations were analysed for primary particles aggregated in flocs. Observed suspended solids were mostly composed of flocs, with maximum sizes ranging from 30 to 212 μm for winter and summer surveys, respectively. Using a relationship defining the floc density as a function of floc size and Stokes' equation for settling, an empirical relationship expressing the floc fall velocity as a function of floc size was produced. This relationship indicates that naturally formed flocs in the size range from 5 to 15 μm would settle faster than both smaller primary particles of higher density, and somewhat larger flocs of lower density, which are however susceptible to break up by turbulence.

Water as excellent natural resource is meant to be of good quality to prevent the outbreak of water-borne diseases. The physical, chemical and biological qualities of water constitute groundwater quality. Water of poor physicochemical quality may have adverse effects on human health and the economy. The physicochemical evaluation of fifteen borehole waters in mile 50 Abakaliki was carried out during the rainy and dry seasons to determine their suitability for drinking using standard analytical methods. During the rainy season, the temperature was 28-30°C; pH, 6.63-8.51; dissolved solids, 1.04-17.01 mg/l; total suspended solids, 0.09-0.98 mg/l; total solids, 1.14-17.99 mg/l; electrical conductivity, 107-328 us/cm; turbidity, 1.27NTU-2.60 NTU total alkalinity, 27.68-82.23 mg/l; total hardness, 70.20-150.84 mg/l; total chloride, 67.30-124.14 mg/l; calcium hardness, 24.50-53.58 mg/l; magnesium hardness, 39.40-97.26 mg/l; sulphate, 30.03-61.88 mg/l; phosphate, 0.25-6.71 mg/l; potassium, 0.00-8.04 mg/l; nitrate, 1.16-8.03 mg/l; iron, 0.00-0.26 mg/l; lead, 0.00-0.05 mg/l; cadmium, 0.00-0.04 mg/l; copper, 0.00-0.23mg/l; chromium, 0.00-0.05 mg/l and zinc, 0.07-2.15 mg/l. During the dry season the temperature was 27-29°C; pH, 6.40-7.75; electrical conductivity, 24-149 us/cm; dissolved solids, 0.10-2.03 mg/l; total suspended solids, 0.02-0.29 mg/l; total solids, 0.13-2.64 mg/l; turbidity, 0.61NTU-1.90 total alkalinity, 19.96-55.97 mg/l; total hardness, 49.61-82.35 mg/l; total chloride, 26.31-80.72 mg/l; calcium hardness, 5.63-29.30 mg/l; magnesium hardness, 30.54-67.30 mg/l; sulphate, 13.88-39.18 mg/l; phosphate, 0.07-3.18 mg/l; potassium, 0.00-4.73 mg/l; nitrate, 0.44-4.95 mg/l; iron, 0.00-0.16 mg/l; lead, 0.00-0.02 mg/l; cadmium, 0.00-0.02 mg/l ; copper, 0.00-0.15 mg/l; chromium, 0.00-0.03 mg/l and zinc, 0.02-0.64 mg/l during the dry season. From the average 7% of cadmium and 33% of lead in the water samples were above the NIS required limits of 0.003 and 0.01mg/l respectively. Generally, the water from the borehole was of poor physicochemical quality and must be treated adequately before being used by humans.
