I began losing fish lately as I added some used railroad ties
impregnated with Creosote. I use two pieces as a plant shelf that
surrounds my small water garden on an outdoor deck. While the body of
the water does not contact the railroad ties, water run off from rain
and when I water my plants might cause some of the substance to enter
the pond water. My dead fish count increased dramatically as I added
the ties. Does anyone have any problems with Creosote used near a
pond? I just had my water quality tested and it was good. I'll remove
the ties if it is suggested that I do so.
