text_A: The leaching of highly water soluble tannins from decaying vegetation and leaves along a stream may produce what is known as a blackwater river. Water flowing out of bogs has a characteristic brown color from dissolved peat tannins. The presence of tannins (or humic acid) in well water can make it smell bad or taste bitter, but this does not make it unsafe to drink.
text_B: Could someone who depends on well water near a bog comfortably rely on Kool-aid, Tang, or any similar product to mask the unpleasant taste of their drinking water?
YES.
