History

[edit]

Clean Harbors was founded in 1980 in Brockton, Massachusetts, by Alan McKim as a four-person tank cleaning business.[4]

In November 1987, the company became a public company via an initial public offering.[5]

In 1984, the company removed 130,000 gallons of fuel oil from the tanker Eldia, which became the largest ship to have been beached off Cape Cod.[6]
