Wa­ter con­sump­tion ad­vi­sory lifted near South Ro­se­vear Gas Plant in Yel­low­head County

The McLeod River Post - - The Patch -

Ef­fec­tive im­me­di­ately, Al­berta Health Ser­vices (AHS) has lifted the wa­ter con­sump­tion ad­vi­sory it is­sued in March 2014 for the five-km ra­dius area of the South Ro­se­vear Gas Plant.

It is im­por­tant to be aware the lift­ing of this ad­vi­sory does not in­di­cate the sul­folane con­tam­i­na­tion of ground­wa­ter has been com­pletely re­moved. Rather, the lo­ca­tion of sul­folane and its po­ten­tial move­ment within ground­wa­ter is now known. The de­ci­sion to lift the ad­vi­sory is based on a com­pre­hen­sive as­sess­ment of all the in­for­ma­tion avail­able, in­clud­ing ex­ten­sive mon­i­tor­ing data and long-term risk man­age­ment plans. Wa­ter wells con­tain­ing sul­folane have been iden­ti­fied and dis­con­tin­ued as drink­ing wa­ter sources. Fur­ther ef­forts are on­go­ing to re­turn aquifers and soils to an ac­cept­able con­di­tion.

Sul­folane is a clear, colour­less, liq­uid chem­i­cal sol­vent used to pu­rify nat­u­ral gas.

The Al­berta En­ergy Reg­u­la­tor (AER) con­tin­ues to work with the plant op­er­a­tors to over­see the im­ple­men­ta­tion of the ap­pro­pri­ate risk man­age­ment and re­me­di­a­tion plans. These plans in­clude wa­ter sam­pling of wa­ter wells near to or in the im­me­di­ate prox­im­ity of the South Ro­se­vear Gas Plant. If you have any ques­tions about these ac­tiv­i­ties, please call the AER di­rectly at 1-855-297-8311.
