GAC Chemical continues acidifying Penobscot Bay. August & September 2018 test results.

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

826/18 sample sites. Satellite image taken May 10 2018
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
