9/9/18 GAC shore acid sampling Sites were selected along the beach/clamflat interface below their abandoned sulfuric acid plant and acid tank. Dark red acidic leachate oozes out at the beach/mudflat interface. See results below photo White line across the upper middle is foam leaking into the bay from 1/4 mile down the GAC property.

9/9/18 pH test results show acid still leaching out along the interface. From left to right in the photo, samples showed pH 6.0 at left end of photo, dropped to 3.5 then to pH 3.2, then rose slightly to 3.7 for the next two samples , finally rising to p 4.2 at the right end of photo

Sites were selected going diagonally from he beach/clamflat interface below the abandoned acid plant and across several of the plumes emanating from the shore
pH test results Sample sites red dots show acid continues leaching out along the interface and onto the flats in a plume. Top site 5.6; next 4.4, next 4.3; lower one a startling pH 2.8!
Discussion: any pH below five will kill fish or damage their reproductive system. Low pH will also liberate dissolved aluminum and other metals into the water column, freeing them from the silt particles they are stuck to. In this low pH environment aluminum ions tend to adhere to the gills of water breathers. Woe to the young salmon venturing forth from the river, that has the misfortune of imbibing that mixture" Her gills will get glazed, and she will exhibit erratic behavior that attracts predators
