I have a collection of post cards from City Hall. Every six months for the past 5 years I received a post card informing me that our local water has "levels of total trihalomethanes above drinking water standards". The card also informs me that "This is not an immediate risk."... "Some people who drink water containing trihalomethanes in excess of MCL over many years may experience liver, kidney, or central nervous system problems, and may have an increased risk of getting cancer." I am told not to worry because they are "currently researching treatment techniques to reduce TTHM (trihalomethane) levels".
My community isn't the only one in the land with water problems. It is admitted that this is a problem throughout the state. At least my area informs us that we "are going to die". I guess knowledge is meant to ease out minds.
I use distilled water. I am reluctant to use spring water since it probably comes from the same aquifer. Usually I distill my own, but if I purchase distilled water, I transfer it into some 4 liter wine bottles saved for that purpose.
Final point---Isn't five years enough time to qualify for "many years"? Also, I wonder why no one else seems to care.
