Incident Description: Ongoing consequences of Freedom Industries leak of 4-methylcyclohexane methanol into the Elk River. ... (Appalachian Waterwatch has been calling this chemical by an abbreviated name that is incorrect. Please correct for the sake of accuracy and credibility.) ... Upper respiratory distress from fumes, intial exposure in our case presumably via tap water entering the humidifier attached to furnace; no mention of that was made in any public announcements, and we overlooked this possible consequence until the day we first flushed 1-14-2014. Subsequent exposures 1) during recommended flushing of the home water system (until I opened windows and turned on the attic fan to ventilate the house), and 2) by showering in hot water after official clearance was given to flush our homes and consider the water safe for all uses. We've since learned that MCHM's boiling point is lower than the boiling point of water, so that it may be expelled as gas as we use our hot water -- or as the water is heated when the furnace picks it up from the humidifier. For a few days I experienced a mild burning/itching sensation and reddened skin after washing hands and showering. My wife, who did not shower here and was not present during this or subsequent flushing operations, was unaffected. The respiratory damage is our biggest concern by far, because it has not diminished with diminished use of the water. Almost a month after the spill, I can report little if any smell in our water but significant ongoing respiratory discomfort. Because public recommendations were made without real knowledge of the substance or its possible effects on humans, we don't foresee drinking this water, cooking with it or using it for food preparation for a long time. In our home, we began noticing significant deposits of *something* in our toilet bowls roughly three to four months before this spill was made public on 1-9-2014. These unknown deposits scrubbed off easily, and we suspect but can't confirm a connection with this leak which may have been ongoing well before the catastrophic failure on January 9.
