I have written in the past that this developed seep is directly above the westerly <br />edge of the old Monarch Mine which may be full of water, and the seep would be over the deepest part of that <br />mine which means that the water pressure would be the greatest at that point. I do not know the vertical <br />distance from the seep down to the Monarch Mine, but I could measure some surface elevations and utilize <br />approximate pitch and directions of the Monarch coal seam to arrive at an estimate. If the construction of the <br />Magpie Diversion simply allowed the Monarch Mine water to flow to the surface, then there is a real problem if <br />the water is toxic. Since this water has never been tested as far as I know, it would be far easier to first test <br />the water. If it meets groundwater standards it would seem to me that no further action would be required. In <br />fact, good water would be a big asset. If it does not meet standards then removing the culvert or filling the <br />culvert does nothing to correct the surface release water as a result of the construction of the Magpie Diversion. <br />W.D.
