JEFFERSON CITY — The owners of a Jefferson County landfill reported a possibility of increased methane gas migration near the eastern Missouri facility.
Valley Disposal Co. oversees a closed landfill in Arnold. The Missouri Department of Natural Resources said Wednesday the company will notify property owners within 1,000 feet of methane monitoring wells that show elevated levels of methane. The notices will be sent to 94 neighboring properties.
The state has been working with the landfill owner on methane issues since 1996. The landfill stopped accepting waste in 1977.
