EDSON – 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.
Alberta Health Services is the provincial health authority responsible for planning and delivering health supports and services for more than four million adults and children living in Alberta. Its mission is to provide a patient-focused, quality health system that is accessible and sustainable for all Albertans.
