ATHABASCA WORKING GROUP 2016-2017 Environmental Monitoring Program in: Changes to the AWG Program TThhe Athabasca Working Group (AWG) environmental moniitoriing program began in 20000 andd cono tiinuuedd for 18 years in 7 northern commmunitiees: Wollaaston Lake/HaH tcheet Lake, Blacck Laake, FoFond du Lac, Stony Rapids, , and Camsell Porttage. Northern commm unity membere s weeree invn ololved with choosing the sampling locations, the typees of plants and ana imala s sas mpplel d,, and wiith the sas mpm lele collections themselves each year.

In consultation with the Athabasca Joio ntt Engagement and Enviroonmental Subbcommmittteeee, ththe AWA G program ended in 2017 and has beeen replaced by the Communin tyy Basedd Envnvironnmem nttalal Mono ittoorining Program (CBEMP) moving forward.

Photo credit: Doug Chisholm Purpose ThT e purposo e of this brochure is to inform the public of the 2016 and 2017 AWG program results in the StStono y RaR pip ds area, and additionally, to conclude the findings of the AWG Program as a whole.

Thhe map shhowo s the Stony Rapids study area.a Water, sediment, and fish were sampled from a rerefef reencce sis tee andd a pottennttial exposure site. RiR ou Laka e was chosen as the reference site because it is not innflf ueuencncede by ururanium opoperations. Stony Lake is referred to as a potential exposure site because it is located downw sts reeamm of urraniuium mining andd milling opep rationns. Two locations were also monitored for air quality neeara Stoonyny Rappidds annd plp ant annd wiildlife samples werre collected when available. Key Parameters The focus of the AWG program was to monitor certain parameters relatedd to uranniuum opperrata ioionsn that were of concern to human and environmmental health. These includded: coc ppere , leadd, nin ckckel, molybdenum, zinc, radium-226, uranium, selenniuum, and arsenic. All ofo these parameterers occcucur naturally in the environment and in parts of northern Saskattchewann they can someetit mees bebe found in high amounts.

In order to help establish whether the key parameter levels founnd inn sammplp ese were nan turally occurring, whether they may have been from uranium operationo s, and whethherer theey poseed a risksk to the environment, the amounts measa ured were compareed: 1) bettweenn reefererenencee andnd potene tit ala exposure sites, 2) to past results, and 3)3 to available guiddele innes.

Wild plants are important because they have traditionally been used for both food and medicine. Samples of blueberry, bog cranberry, and Labrador tea were collected in 2016 and 2017 from the Stony Rapids area.

Since AWG monitoring began, the key parameter levels in all three plant types have remained low in Stony Rapids and all other AWG communities. Air Air quality was monitored at two locations near Stony Rapids in 2016 and 2017 by measuring radon levels. Radon is an odourless and tasteless gas produced by the natural breakdown of uranium and radium-226 in the soil and water. As a result, radon levels are naturally higher in areas where uranium is found in the ground. Seasonal differences may occur because the ground thaws and releases radon gas into the air during the summer months.

The graph displays the Stony Rapids results since 2006. Stony Rapids radon levels have been low over the entire duration of the AWG program. Even the highest level measured in 2010 is a low amount. Conclusion Over the 18 years of sampling that made up the AWG Environmental Monitoring Program, there were no concerns regarding the amounts of key parameters in the water, sediment, fish, mammals, and air in the Stony Rapids area. Thank You for 18 Years The AWG program was made possible thanks to the involvement of northern residents. Special thanks to Billy Joe Mercredi who did a great job collecting AWG samples from the Stony Rapids area for many years.

Thank you to the AWG members, including representatives from the seven northern communities and industrial partners, Cameco Corporation and Orano Inc.
