Since 1980, field service centers have been strategically located across North America to provide emergency response services and perform planned work on customer locations.

Founded by Alan S. McKim, Clean Harbors began as a four-person tank cleaning business.

Mr. McKim continues to lead the company as Chief Executive Officer and Chairman of the Board.


Clean Harbors has achieved steady growth, both geographically and in terms of service offerings, through the acquisition of new facilities, equipment and personnel in order to respond to client needs. In 1986, their laboratory chemical packing services, CleanPack®, was formed to provide industries, schools, universities, and communities with vital services to manage the collection, packaging and disposal of laboratory chemicals and household hazardous waste. Clean Harbors provides comprehensive hazardous waste handling and disposal throughout North America.
