July 5, 2019; Liverpool, NS:   Region of Queens Municipality continues to receive inquiries from the public regarding an odour at various times near Bristol Avenue, Liverpool, and Highway #3, Brooklyn. Region representatives continue to proactively consult with experts to try to determine the cause of the odour, and to pursue a solution. The Municipal Sewage Treatment facility located on Hank Snow Drive continues to meet all regulatory effluent requirements. The local odour is suspected to be from the marsh area located behind the businesses on the seaward side of Bristol Avenue and Hwy. #3 to Brooklyn, the tidal shoreline principally at low tide, and the operating sewage treatment facility.  The prevailing wind direction generally dissipates odour, however certain wind direction and humidity levels can result in noticeable odour levels.  It should be noted that the Kentville/New Minas area is also experiencing a similar odour issue.

Proactive efforts over past weeks have included the flushing of our sewage lines from Milton, as well as on Bristol Avenue, to the sewage treatment plant. Skimming of the surface of the primary cell was completed early this week and last week to remove any fats or oils which may be present, which could potentially generate an odour.

It should be noted that residents outside of local sewer serviced areas have contractors pump out their septic tanks every several years, and those contractors utilize the Septage Receiving station on a regular basis, with that waste being processed by the sewer treatment plant. No person is known to be dumping raw sewage into the wetland area and any stories to that effect are deemed to be untrue.

The Region also removes rainfall collected in our second generation landfill cells, with that leachate being hauled to the Receiving station on a daily basis. This is the large truck that residents may witness entering and exiting the sewer treatment facility several times a day, all year long.

Additionally, an expert who was consulted has advised that although the dredge cycle for sludge in the lagoons was projected to be approximately 25 to 30 years, and de-sludging would be premature, it may be beneficial to de-sludge the primary cell in view of recent odour concerns. A recommendation will be taken to the upcoming Council meeting to be held on July 9th to approve the hiring of a contractor, at the earliest opportunity, to perform this de-sludging by means of a self-contained odourless process. The estimated cost for this work is $150,000 and is expected to take two weeks to complete.

Staff will continue to research and consult with experts in their areas of expertise. Activities will occur towards ruling out potential causes and seek solutions, as timely as possible.
