  <dc:description>&lt;p&gt;&lt;span&gt;A heated purge-and-trap gas chromatography/mass spectrometry method was used to determine the &lt;/span&gt;&lt;i&gt;cis&lt;/i&gt;&lt;span&gt;- and &lt;/span&gt;&lt;i&gt;trans&lt;/i&gt;&lt;span&gt;-isomers of (4-methylcyclohexyl)methanol (4-MCHM), the reported major component of the Crude MCHM/Dowanol™ PPh glycol ether material spilled into the Elk River upriver from Charleston, West Virginia, on January 9, 2014. The &lt;/span&gt;&lt;i&gt;trans&lt;/i&gt;&lt;span&gt;-isomer eluted first and method detection limits were 0.16-μg&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;i&gt;trans&lt;/i&gt;&lt;span&gt;-, 0.28-μg&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;i&gt;cis&lt;/i&gt;&lt;span&gt;-, and 0.4-μg&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt; Total (total response of isomers) 4-MCHM. Estimated concentrations in the spill source material were 491-g&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;i&gt;trans&lt;/i&gt;&lt;span&gt;- and 277-g&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;i&gt;cis&lt;/i&gt;&lt;span&gt;-4-MCHM, the sum constituting 84% of the source material assuming its density equaled 4-MCHM. Elk River samples collected&amp;nbsp;⩽&amp;nbsp;3.2&amp;nbsp;km downriver from the spill on January 15 had low (⩽2.9&amp;nbsp;μg&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt; Total) 4-MCHM concentrations, whereas the isomers were not detected in samples collected 2 d earlier at the same sites. Similar 4-MCHM concentrations (range 4.2–5.5&amp;nbsp;μg&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt; Total) occurred for samples of the Ohio River at Louisville, Kentucky, on January 17, ∼630&amp;nbsp;km downriver from the spill. Total 4-MCHM concentrations in Charleston, WV, office tap water decreased from 129&amp;nbsp;μg&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt; on January 27 to 2.2&amp;nbsp;μg&amp;nbsp;L&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt;on February 3, but remained detectable in tap samples through final collection on February 25 indicating some persistence of 4-MCHM within the water distribution system. One isomer of methyl 4-methylcyclohexanecarboxylate was detected in all Ohio River and tap water samples, and both isomers were detected in the source material spilled.&lt;/span&gt;&lt;/p&gt;</dc:description>
