Ethylene Oxide Update: November 26, 2019

The Lake County Health Department has received the first set of results from the second phase of ethylene oxide (EtO) air monitoring. The initial results include samples collected on three separate days from October 26 to November 2, 2019. This phase of the air monitoring is set to continue through January 2020 and is being funded by the Illinois Environmental Protection Agency. 

To make the results more user-friendly, the Health Department is now linking to an online spreadsheet rather than embedding a table on this page. The spreadsheet will be updated as additional results are received.

The results of the testing can be viewed at:
