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 180 piezometers are monitored as part of this 

 project. 



Figure 3.14 shows the drawdown contours in the Hart Coal seam aquifer as of December 2002. Note 

 that the 1 -metre drawdown contour extends less than 1 kilometer south of the International Boundary. 

 There have not been significant changes in the cone of depression over the past several years, suggesting
