The highest <br />concentration (2.2%) was found at probe GW -11 -Deep. We continue to see this concentration <br />decreasing due to the improvements made to landfill gas collection in August and September of <br />this year. We will continue to pay close attention to this probe. <br />If you have any questions, please contact me at extension 8-8504. <br />Sincerely, <br />W.
