Evacuated LTER lysimeters that were installed in fall 2024 since conditions were very dry many did not yield leachate in November or December 2024. These lysimeters were evacuated on 3/7/2025 and left over the weekend. The lids were completely off from DF3-1 and DF3-6. On 3/11/2025 they were checked for pressure, the volume of leachate approximated and then the leachate dumped before re-evacuating with the regular sampling. - Stacey
