This is a Task Assignment Notification Change Order Form for Florida Department of Environmental Protection Contract No. HW554, involving APTIM Environmental & Infrastructure, Inc. as the contractor. The document serves as Change Order No. 1 to Task Assignment DC004E for groundwater monitoring services at the Altamonte Springs Dry Cleaners facility (Site ID ERIC_5459). The DEP Contract Manager is John Sykes III, and the contractor representative is Eric Kramer, PE. The change order was executed in March 2019 and involves a second site visit to complete biennial groundwater sampling that could not be finished during the initial monitoring event.

The change order authorizes an additional $1,110.00 (final cost $1,081.77) to address sampling issues caused by detached passive diffusion bags in monitoring wells MW002 and MW016 and inaccessibility of well MW017 beneath a parked vehicle. The additional work includes specialized downhole equipment and submersible pump deployment to sample the affected wells conventionally. The final deliverable is a Biennial Groundwater Monitoring Letter Report with DEP EDDs, due March 26, 2019, with total task amount increased to $6,966.27. The scope expands the original task completion date from March 28, 2019 to May 27, 2019, adding 60 days to the task period. Labor costs total 45 hours, and detailed cost estimates are provided for equipment, laboratory analysis, field expenses, and materials necessary to complete the supplemental sampling activities.
