3.3.2 Ground-Water Monitoring 



3.3.2.1 Saskatchewan 



In 1996 nineteen new piezometers were installed in the Hart Coal Seam and a further eighteen 

 piezometers from the Frenchman aquifer testing program were added to the supplementary supply 

 monitoring network that year. With these extensive additions, no new piezometers have been added to 

 the monitoring network since that time. Currently, about 1 80 piezometers are monitored as part of this 

 project. 



Figure 3.14 shows the drawdown in the Hart Coal seam for as of December 2001. Note that SaskPower 

 determined an error in their contouring for previous years. The drawdown contours on revised maps for 

 1999 and 2000 are similar to the contours for December 2001, with the 1-m drawdown contour 

 extending approximately 1 kilometer south of the International Boundary. The revised drawdown 

 contours do not show significant changes in the cone of depression for the past several years, suggesting
