July 24, 2019 Update: Additional air monitoring results received

Both Medline and Vantage have conducted independent air monitoring during the month of June, some of which was done at sites also being monitored by the Health Department, the Village of Gurnee and the City of Waukegan. We have received one set of results from Medline, which can be viewed here:

July 22, 2019 Update: Additional air monitoring results received

The Health Department has received additional air monitoring results from samples collected on five separate days from June 14 to June 22, 2019 in Lake County.

June 21, 2019 Update: Initial air monitoring results received

The Health Department has received initial air monitoring results from samples collected on three separate days from June 6 to June 10, 2019 in Lake County. This initial data represents only three days of sampling, so conclusions about potential impacts to health cannot yet be made. The Health Department is sharing all results with the Village of Gurnee, City of Waukegan, U.S. Environmental Protection Agency (EPA) and Illinois Environmental Protection Agency (IEPA) as the data becomes available. Updates will be provided to the public on this web page.

Please note that on certain days, not all monitoring locations are sampled. These days were randomly selected during the 30-day period. Samples collected on these days are in addition to the samples collected on the regularly scheduled days. On these random days, four monitoring sites are being sampled.

Lake County Air Monitoring Wind Rose Maps

The maps posted below show the monitoring locations, air monitoring results by day, and a wind rose, which shows the wind information for each sampling day (i.e., wind direction, intensity, and percentage of time wind was blowing from the direction indicated).

Note: With the assistance of US EPA and Illinois EPA, we are currently reviewing the wind rose data regarding wind intensity (speed). If it is determined that corrections are required, they will be posted to this site, along with an explanation.

Wind roses are very important in determining the potential impact of a source of pollution. For more information, please see the U.S. EPA’s How to Read a Wind Rose (PDF).

Lake County Air Monitoring Lab Reports

Note: In the samples report ERG Jun 14_22 eto, samples from Jun 21 – 22, 2019 indicate a “sampled” date of June 22, 2019. The convention has been to report the date the sampling began as the “sampled” date. A corrected report will be posted soon, indicating the “sampled” date as June 21, 2019.
