We finally have some information on 4-methylcyclohexene methanol from the source

tells us detection limit of WV chemical spill water testing: 10 parts per billion or 1/100 parts per million.

The 4-methylcyclohexene methanol (MCHM) spilled in West Virginia was manufactured by Eastman Kodak. This week they finally released some of their toxicity research at http://www.eastman.com/Pages/Eastman-Crude-MCHM-Studies.aspx

I haven't had a chance to look at them yet - other than to see that they are over a decade old (1997 & 1998 on the ones that I glanced at) and they were all short term animal studies on small cohorts.  Not the most reassuring basis for determining a "safe" level of exposure.

I just saw that Wired has a great writeup on by Deborah Blum
