On August 4, 2013, Friends of Penobscot Bay carried out pH testing of water and soils on both side os the first cove of Stockton Harbor near GAC Chemical. The pH was near neutral (7) in the outer part of the cove. A slight increase in acidity closer to shore and above the concrete debris under the old sulfuric acid factory & storage tank. Acidity increased sharply in the gray material on the path leading to the old factory and out in the gravel and mud directly beneath it.

Test gear: Ferry Morse Electronic Soil Tester and Luster Leaf Rapitest. Tests for presence/absence purposes only, not conclusive.
