Super storms and storm surges lead to more contracts for CLH. The company's Field Services segment provides various environmental cleanup services on customer sites or other locations on a scheduled or emergency response basis. These services include tank cleaning, decontamination, remediation and spill cleanup.

Its environmental services provide a comprehensive array of sustainable and cost-effective environmental solutions. Last Monday, Clean Harbors announced that it had acquired Evergreen Oil out of bankruptcy through the U.S. Bankruptcy Court for the Central District of California.
