Petroleum Products Spillage and Its Effect on Soil at Mbalim Gwer East Benue State Nigeria
Abstract
Soil samples were studied to provide information on the level of damage ( if any) done as petroleum products were spilled from vandalized pipelines 10 years after . Petroleum products are volatile and evaporate in a short time, it is very difficult to determine their presence on soil after some time , instead the soil was analyzed in order to determine the quantity of essential elements still present in the soil after the spill Therefore five (5) locations ( around Mbalim- at the immediate point of spill, one kilometer north, one kilometer South, one kilometer East and one kilometer West) were chosen. Basic elements of soil fertility - pH of the Soil , phosphorus , Nitrogen , Potassium , Organic Carbon and Manganese were determined The soil samples were heavy , hardly absorbed water, displayed acidity of 6.26 , 3.8% nitrogen , 6.6%phosphorus ,5.2% potassium and the texture loamy and sandy. Agricultural use of this land was considered a hard task except the process of remediation is applied. Aeration of the soil at the contaminated site was already sufficient , thermal remediation to raise subsurface temperatures to volatize chemical contaminants out of the soil was equally going on as the site was exposed to enough sunlight. Bioremediation including landfarming, biostimulation and bioaugmentating soil biota is recommended. In areas of intensive farming like Benue State where crops are harvested at least once a year and no animals browse the fields, human intervention in the form of traditional fertilizer, animal manure or muck, made from the straw bedding of cattle that has fermented for a period is also recommended.
