Contaminated sites by hazardous substances are a major environmental concern throughout the world, because most contaminants can persist for many years in soil and sediments, where they have the potential to adversely affect human health and the environmental. Our Soil Remediation solution commence with a research study of the site, for a good understanding of the nature of contaminants the risks they pose, the best remediation technology for dealing with soils and sediments, and reasonable approaches to management of the problem. We have successfully completed remediation projects, among which are the remediation of crude oil polluted site at km.199 Izon-Sarkin Pawa NNPC pipeline
Environmental post Impact Assessment of Oil Spill From PPMC Pipeline at Km.198 Izon, Niger State
The PPMC pipeline carrying crude oil from Escravos, near Warri, to Kaduna Refining and Petrochemical Company got ruptured at km. 198 Izom – Sarkin Pawa, Kafin Koro Local Government Area, Niger State. This resulted in spillage of unknown quantity of crude oil which polluted the environment.
Immediate contingency measure was to contain the spill by channeling into three large pits dug at the site, where it was burnt and the ruptured pipe was replaced. The spilt oil affected the soil, farmlands, vegetation, aquatic life, soil microorganisms, etc.
Furthermore, after the damaged pipe was replaced, which foreclosed any possibility of oil leakage, it was discovered by PPMC officials that the surface at the point of leakage appears oily particularly at the beginning and during the wet season, years after.
This EPIA study was commissioned to determine the extent of pollution and to quantify and evaluate the impacts of the pollution on the environment, and recommend mitigation measures. It was also required to determine the source of oil, which appears on the surface even after the pipeline was repaired and doubly checked.
