Chris,
Thanks for the update. I'd be curious to know if your date analysis of the
stratification in the deposit justifies your assertion that the cistern was
open and receiving deposits over a twenty year period. Kent Schneider
reported that a local informant told him that the majority of the deposit
was created by a single clean-out event of the basement at the time the
house was hooked up to city water. Don't know if he documented this, l but
sometimes it's hard to sort out the baloney from the Spam (tm). Either way
the safety advice is still good.
