Our employee owners have been supporting a remediation project in the Philippines. Diesel fuel leaked from a storage tank and seeped into the groundwater and soil. Emergency measures were taken but clean-up was delayed due to COVID restrictions. After some of the more strict COVID restrictions were lifted, CSS scientists joined the environmental due diligence crew to continue the assessment and start the remediation process.

Currently, our team is assisting with bringing this project to the finish line, which will be a major accomplishment given the delays and challenges, including cultural differences, heightened security, the remote location, and continued COVID restrictions.
