Environmental compliance and influence of fuel dispensing infrastructure on groundwater quality in urban and peri-urban environment

The study assessed the level of compliance to Environmental Impact Assessment, Conformity to 15m sitting distance to dispensing outfit, and Proximity to Public facilities. Also, the effect of these dispensing outfit on groundwater quality of hand-dug wells at close proximities to petrol filling stations in Ado-Ekiti metropolis of Ekiti-State were equally considered. The result revealed that only12% out of the Seventy-two (72) filling stations examined complied with the guideline while 88% fall out of compliance. Two water samples each were collected from Five (5) different stations along the major roads within the study area. The physicochemical and heavy metal parameters of the water samples were analyzed in the study area. The sample were collected from five selected functioning petrol stations above 25 years of establishment in the metropolis with hand-dug wells within and around its premises. Samples were analyzed for physicochemical and heavy metal parameters such as Temperature, Turbidity, Total Hardness, Total Suspended Solid, Conductivity, Chloride, Manganese, Chromium, Iron and Zinc. Results were compared with the World Health Organization Standard for Drinking Water Quality which showed abnormality in concentration of some parameters such as Turbidity, Chloride, Chromium and Manganese The results from physicochemical and heavy metal water samples revealed that activities at the petrol filling stations, coupled with non- compliance is some areas within the area may have contributed to the contamination of the groundwater which is an indication of unchecked and uncontrolled activities of filling stations. These may pose significant health risks to both consumers and the environment at large in the vicinity.
