Volunteer and compensation hours.
On 3 June 2013, two areas totaling 13.4 acres were treated with a liquid formulation of endothall (Aquathol K) at a target concentration of 1500 ug/L (1.5 mg/L) active ingredient (ai) to control curly-leaf pondweed (Potamogeton crispus). Water samples were collected from each sample site using an integrated water sampler which collects water from most of the water column. Water samples were collected at intervals of approximately 1, 2, 4, 6, 8, 24 and 48 hours after treatment (HAT) at sample sites in treatment areas. Water samples were collected at intervals of approximately 1, 3, 5, 7, 10, and 14 days after treatment (DAT) at sample sites in untreated areas. Samples were taken to shore after completion of each sample interval, and 3 drops of muriatic acid were added to each sample bottle to fix the endothall and prevent degradation. Samples were then stored in a refrigerator, until shipped to the US Army Engineer Research and Development Center (ERDC) laboratory in Gainesville, FL for analysis of endothall.
