7. Alkali water occurs naturally in the Dakotas

Most North Dakota waters are alkaline, with a pH value above 8. Acidic water (pH below 7) is not common in most of North Dakota; however, some reports indicate acidic water in the western part of the state in proximity to lignite coal veins.

High alkalinity may cause digestive upsets, laxative action, poor feed conversion, and reduced water and/or feed intake.

My recollection is that the "laxative action" lasts a few days until your system adapts.
