This study examines the contribution of Zobe dam to the socio-economic development of Makera Community Dutsinma LGA, Katsina State north-western Nigeria. The study identified types of socio-economic activities supported by the dam and their impact. Total of 392 questionnaires was administered to adults target population using stratified random sampling technique. Descriptive and inferential statistics were used to analyze the data. Findings revealed main economic activities supported by the dam are farming (60.46%), fishing (30.10%), domestic water supply (5.52%) and livestock watering (3.057). The positive contributions of the dam include an increase in the availability of social amenities and resident's standard of living. Specific impacts were increased income, increased crop yield, increased farm sizes, commercial fishing and increased access to water supply sources. The survey also revealed the dam is a major pull-factor with 79.59% respondent's decision to settle in the area influenced by the dam. The negative impacts were; occasional floods that erode crops, farmlands, the introduction of new pest and spread of water associated diseases (schistosomiasis, malaria, and typhoid in decreasing magnitude). ANOVA test showed no significant difference in literacy level, occupation and water use among residents. Analysis of water quality to determine the impact of activities was recommended.

This study examines the portability of rainwater in Langtang north and south LGAs of Plateau State-Nigeria using arithmetic water quality index method with 10 samples collected directly from zinc and aluminum rooftops in 10 selected communities. Twenty-six water quality parameters were analyzed in the field and laboratory. Temperature, pH, EC, TDS and turbidity were analyzed in the field using appropriate equipment as well as color, odour and taste. The most probable number was used to determine the presence of bacteria, while photometric and the Atomic Absorption Spectrophotometer (AAS) were used to determine the concentration of the various chemical parameters (USEPA, 2012). The results revealed unobjectionable taste,

A preliminary analysis of the chemical quality of domestic water sources in Langtang area was undertaken to determine variation in quality of water sources and how it meets the Nigerian Standard for Drinking Water Quality (NSDWQ). Using stratified random sampling technique, 50 water samples were taken from five different sources: rain, dams, streams, boreholes and hand dug-wells. Samples were tested in the laboratory for 20 parameters using standard methods described by USEPA (2012) and results subjected to ANOVA and independent sample t-tests. Temperature (28), turbidity (15), Ca (85), Mg (30), Cl (275), Fe (1.2), Pb (0.1) and Cd (0.002) had average mean above limits. ANOVA result shows significant variation in water quality with p-value of 0.001. Post-Hoc test revealed significant variation in 80% of the parameters tested: temperature, turbidity, EC, CaCO3, F, TDS, Ca, Mg, NO3, Fe, Cu, Al, Pb, As and Cd. Only pH, Cl, Mn, Cr and Zn do not show significant variation. Independent sample t-test also show significant variation in water quality to the Nigerian Standard for Drinking Water Quality (NSDWQ), which implies the water is unsuitable for human consumption. This study has demonstrated that despite differences in the protection levels of water sources, some parameters may still be the same across sources. It is therefore recommended that detail analysis of each water source be carried out to identify parameters responsible for pollution, as well as remediation the of water before consumption.
