A total of twelve water samples consisting of four boreholes, four wells, and four taps water, including one from Chanchaga water works were collected and analyzed for some physicochemical parameters and heavy metals using standard procedures. The results showed that the average physicochemical properties of tap, well and borehole water samples respectively were pH, 6.60, 6.62 and 6.67, turbidity, 1.58, 3.42 and 3.15 NTU, total suspended solids, 0.03, 0.09 and 0.00 mg/L, total dissolved solids, 0.96, 4.68 and 1.14 mg/L, total solids, 0.99, 4.79 and 1.14mg/L, electrical conductivity, 158.25, 799.25 and 778.25 µЅ/cm, alkalinity, 13.50, 50.00 and 117.50 mg/L, chloride,18.75, 74.00 and 47.25mg/L, total hardness65.50, 227.75 and 149.50 mg/L while the heavy metal concentrations in tap, borehole and well water samples were Cu, 0.02, 0.20 and 0.33 mg/L, Mn, not detected, 0.23 and 0.32, Pb was not detected in all the samples and Fe, 0.21, 3.10 and 2.12 mg/L respectively. All the parameters analyzed were below maximum permissible limits specified by WHO except the total hardness of well water and concentration of Fe in well and borehole water which were above the maximum permissible limits. It can be concluded that the three sources of water at different locations in the study area are safe for human consumption at the time this research was conducted.

The labeling information, temperature, pH, turbidity, electrical conductivity, total hardness, chloride, alkalinity, lead, copper, manganese and iron contents of the water samples were determined using standard methods. The investigation revealed temperature, pH, electrical conductivity, total hardness, chloride and alkalinity of the samples to range between 26.5+0.50-28.0+0.00 o C, 6.20+0.09-7.33+0.30, 13.5+1.50-317.5+1.50 µScm-1 , 13-125 mg/L, 2.89-31.36 mg/L and 5-60 mg/L, respectively. Lead and copper were not detected in all the samples except SB10 with 0.01 mg/L of copper. Similarly, manganese was detected in six samples at concentrations between (0.02-0.08 mg/L) while iron ranged between 0.01-0.16 mg/L). The physical, chemical and heavy metals composition of the water samples complied with World Health Organization (WHO) and Standard Organization of Nigeria (SON) permissible limits for drinking water except the pH of one sample (SB8) that was below the permissible limit. However, 60% of the brands had no manufacturing and expiry dates on their label as required by the Nigeria's National Agency for Food and Drug Administration and Control (NAFDAC). Therefore, periodic evaluation and monitoring by concerned agencies should be intensified to ensure that bottled water producers in the state strictly adhere to the standard operating procedures.

and Gidan Igwai areas of Sokoto were collected and analyzed in the laboratory. The pH and
the electrical conductivities (EC) of the water samples were also determined. The mean
results obtained from the analyses were pH (7.68, 6.72) and electrical conductivities
(1061µs/cm, 1057µs/cm) for Gidan Dare and Gidan Igwai, respectively. The results also
showed mean arsenic concentrations of 0.110mg/L and 0.217mg/L for Gidan Dare and
Gidan Igwai water samples respectively, which are above the World Health Organization
(WHO) drinking water guideline. Wells in Gidan Dare and Gidan Igwai were found to be
contaminated with abnormal concentration of arsenic, high enough to cause serious adverse
health effects to its consumers. The high arsenic concentrations could be attributed to both
natural and anthropogenic activities such as erosion, underground weathering, toxic
chemicals, improper waste and sewage disposal waste from industries, agricultural activities
and vehicular emissions.

The sample was purified and the asphaltenes fraction precipitated with n-hexane, fractionated into fractions A and B based on solubility and polarity with hexane/toluene mixture at a fixed ratio while resins recovered from maltenes was fractionated into subfractions X, Y, Z by liquid adsorption chromatography on a silica/alumina adsorption column with dichloromethane/methanol mixed solvent in the ratio of 4:1, 3:2 and :2:3, respectively. The results showed that crude asphaltene and its subfractions absorbed light of longer wavelength (465-640 nm), indicating that they are made up of polynuclear aromatic compounds. The results also revealed the presence of alkyl side chains and major oxygenated groups in both crude asphaltene and its subfractions (A and B). The spectra of crude resin and its subfractions showed that they absorbed radiation of longer wavelength (490-580 nm), which are character of polynuclear aromatic compounds with the extended conjugated system. However, IR spectra revealed that all the fractions including the crude resin contained aromatic rings with alkyl side chains and oxygenated groups.
