--~ <br /> <br />Jeff Clayton <br />-2- <br />September 14, 1989 <br />source of inflows is the ventilation shaft area. Seeps are found below East <br />Raotcap Creek and Stevens Gulch and at the edges of the alluvial colluvial <br />bodies. The water quality has deteriorated from a neutral water with a <br />conductivity around 2200 mmhos/cm to a very alkaline water (pH of 9) with an <br />EC of 4000 mmhos/cm. I would guess that this may be attributed to the <br />presence of surplus rockdust, but we should also check the quality of the <br />Steven's Gulch well field water which is used for dust suppression. <br />CWB/yjb <br />cc: Susan Mowry <br />9673E <br /> <br />:.^. <br />.... .. u.. .~.: ~~.s,.~,e <br />
