Home My WebLink AboutDERR-2025-001449VCP/Brownfields Section - Site Visit Report SITE NAME: Mayflower Mine SITE LOCATION: Wasatch County DATE OF SITE VISIT: 21 February 2025 PURPOSE OF SITE VISIT: DERR (David Bird) oversight of Phase 1 remedial action. FIELD OBSERVATIONS: The DERR visited the Mayflower VCP site at ~8:22 am on 21 February to observe conditions at the site. Specifically, the DERR and Extell were interested in observing the McHenry Campground (4997675) surface water sampling location at the Jordanelle State Park where surface water east of the Mayflower VCP site and U.S. 40 makes its way to the Jordanelle Reservoir. In early February, surface water sample results from this location exhibited higher turbidity levels, along with higher concentrations for cadmium, iron, and zinc. It was decided that a visit to the site was in order to assess the situation. The DERR and Extell walked to the 4997675 sampling location and from there upstream beside a beaver pond and then to the U.S. 40 culvert outlet and Cunningham Tunnel location. The culvert outlet has water and sediments/plant material backed up to approximately 40% of the height of the opening. Extell has recently spoken with Jordanelle State Park personnel about dredging the channel and breaching the beaver dam to allow for better flow of this stream. The DERR left the site at ~9:30 am. SPLIT SAMPLES COLLECTED: N/A IS THE WORK BEING PERFORMED IN A MANNER CONSISTENT WITH THE ACCEPTED WORKPLAN? N/A View toward the north of a beaver pond downstream of the U.S. 40 Culvert Outlet and Repository. Water flowing into the pond appeared clear. Some turbidity can be seen in the water of the pond, presumably from wildlife disturbance. This pond is upstream of the 4997675 surface water sampling location in the Jordanelle State Park. View toward the west of the U.S. 40 Culvert Outlet downgradient of the Repository. No turbidity was noticeable in the water, however, the rust colored sediment and/or plant type material appears to have built up in the channel over the last four to five years.
