Uranium Exploration/Mining Risks to Source Water Protection Areas

Uranium Exploration/Mining Risks to Source Water Protection Areas

Due to the recent activity of uranium exploration companies, several Source Water Protection (SWP) regions in Eastern Ontario are potentially at risk. Uranium exploration companies have been active in the Mississippi-Rideau watershed as well as in Haliburton and West Quebec. Additional areas may in time be affected by uranium exploration when one considers data from Geological Surveys.

Beginning in June 2007 MVFN has been involved in raising awareness of issues relating to the environmental risks posed by uranium mining in the Mississippi-Rideau SWP region. For a historical review of MVFN’s involvement and the issue see an article posted here in January.

Later at the inaugural meeting of the Mississippi Rideau Source Water Protection (MSRWP) committee in January 2008, a member inquiry was tabled by MRSWP Committee member Patricia Larkin requesting that a report be prepared to provide a better understanding of the “potential impacts of uranium exploration, mining and processing in Eastern Ontario and the legislative scope of the Clean Water Act to respond to these concerns”. They were also to inform neighboring SWP regions. We informed other NGO members of the Water Guardians Network, of the issue. The following other SWP regions should be most aware: Quinte, South Nation, Cataraqui and the ‘Trent Conservation Coalition.’

The local conservation authority has also produced a preliminary staff report with regards to the threat posed by uranium exploration and mining in the MRSWP region. This report and the member inquiry can be found in the minutes of the February 7, 2008 meeting of the MRSWP Committee (a large pdf file) at the following link

We have also posted  CItizens’ Uranium Inquiry Submission Sharbot Lake April 1, 2008 to provide a wider context for the issue as it may affect neighbouring SWP regions . Please note this is also a large pdf file.

Climate Change Awareness: Lake and River Water Temperature Monitoring

Press Release

Report on results of Lake and River Water-Temperature Monitoring in the Mississippi Watershed:

Mississippi Valley Field Naturalists carried out a lake and river temperature monitoring program over the August 2006 long weekend as an `Open Doors to Nature Project’in celebration of the 75th Anniversary of Ontario Nature (Federation of Ontario Naturalists). A short report outlining the objectives and results was prepared by Paul Egginton, MVFN.

At the end of December 2006, all of the raw data plus copies of the report were deposited at the offices of Mississippi Valley Conservation in Lanark, and are available for viewing there. The report is also posted here. A final report with additional peripheral data important for putting the survey findings into perspective, will also be posted.

By all counts this project was a great success. We measured our patient’s temperature (the Mississippi Watershed) and found it to be, on the basis of nearly 675 surface-readings (and nearly 1400 readings in all), on average, about 26.4 C. Many scientists are warning that air temperatures will continue to rise. Lake and river temperatures will surely follow and there may be significant impacts on the Mississippi Watershed.

To help us adapt to such change it will be very useful to know whether mid-summer water temperatures do increase in future and at what rate. Our report suggests that there is more work to be done. However, MVFN wishes to sincerely thank all those who encouraged, supported and took part in this water-temperature monitoring effort. Special thanks to Susan Lee of Mississippi Valley Conservation who contributed greatly by providing logistical support for this project.
