Effects of very low frequency electromagnetic method (VLFEM) and physicochemical change of Zango abattoir

The study examined the impact of livestock dung on ground water status in the study area. To achieve this, a very low frequency EM survey was conducted; the aim and objective was to detect fractures in the subsurface. VLF data were acquired at 5m intervals along two profiles, with maximum length of 60m in the North-South direction. The fraser filtered real component of the processed VLF data detected anomalous zones/ litho logical boundaries that may possibly serve as conduit for the movement of solid waste contaminant into the ground water. Water sample from the hand dug wells were collected in prewashed 250ml plastic container and analyzed in the Laboratory. Result obtained shows that physicochemical analysis deviate from WHO and SON standard and complement with VLF EM survey. This has shown that it is not free from certain heavy metals, as such, the water is not suitable for human and livestock consumption. It is recommended that the ground water in Zango should be treated using coagulants before use.Keywords: Abattoir, Livestock, SON, Water quality, WHO, Zang

Physico-chemical evaluation of wastewater in Katsina metropolis, Katsina Nigeria

The study was designed to assess the physico-chemical parameters of wastewater at Katsina metropolis from June-August, 2015. Water samples were collected twice in a month at three (3) sampling sites designated as K/Marusa, K/Durbi and K/Sauri and was analyzed for surface water temperature, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD) and turbidity. These parameters were compared with their sampling sites in which a significant difference was observed (P<0.05). The water is well oxygenated and alkaline in all locations (7.7,7.9 and 7.67), temperature were relatively high (26̊C,25.7̊C and 25.8̊C), DO mean values were 4.6, 3.9 and 4.8 while BOD were 2.6, 2.53 and 2.53. Turbidity values were 11.5, 15.8 and 11.2. Therefore, measure should be put in place to regulate improper refuse disposal into the wastewater and a possible creation of wastewater treatment plant so as to avoid adverse conditions.Keywords: Physico-chemical Parameters, Pollution, Wastewater, and Katsina Metropoli
