Clean HarborsCORUNNA, Ontario –(BUSINESS WIRE)– Clean Harbors Canada, Inc.’s Lambton facility experienced odour complaints from the nearby community and the Company has taken measures to reduce these odours in an effort to ensure that the problems are minimized in the future. Recent testing indicates that emissions from the site are within the Ministry of the Environment health standards.

The source of the intermittent odour emanating from the facility is leachate that has pooled at the base of the active landfill excavation and is stored in leachate ponds. The facility is actively addressing this problem by applying additional odour reagents and neutralizers, covering the leachate pond, and conducting activities during favourable meteorological conditions.

The Company purchased a special surfactant/enzyme combination that emulsified the leachate to eliminate the odours coming from the leachate pond. In addition, a custom made tarp was installed over the pond to further encapsulate the odours.

“We are taking aggressive steps to significantly reduce odours coming from the leachate in the active landfill,” said Clean Harbors Lambton Facility General Manager Chris Small. “Excellent progress has been made over the past weeks with the addition of new chemical neutralizing agents to the leachate pond, and the new geotextile cover. These actions have had a positive impact in reducing odours.”
