Police and Conservation Officers are continuing their investigation into someone dumping crude oil into the Town of Shaunavon's sewage lagoon sometime between June 4 and 12.

The clean up has already been done at the site, at a very substantial cost to the town.

Shaunavon Mayor, Kyle Bennett said, "The site has been cleaned up already, and we do have some oil-absorbing booms out on the lagoon stand. We're monitoring, and just collecting anything along the edges that may be residual. Everything had to be hauled away to an oilfield waste facility, and it's been reported to our Water Security Agency and the Ministry of Environment and all that as well. It wouldn't affect our water supply whatsoever. This is our waste water facility and there's certain measures that we have to take before the lagoon water is released into the watershed."

The town is  asking anyone with information or if you may have observed any vehicles at the Shaunavon Lagoon to contact the Town Office, the local Conservation Officer or RCMP, or the Saskatchewan Turn In Poachers and Polluters line at 1-800-667-7561 or #5555 from a SaskTel cell phone.
