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 large amounts of tannins (or humic acid) in well water can make it smell bad or taste bitter, and these effects can serve as a marker for other chemicals that often co-locate with humic acid and can render the water toxic for human consumption.
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?
NO.
