Aptim Environmental & Infrastructure, LLC

5/25/2025

The following proposed Task Assignment Chane Order (TACO) DC015E TACO #1 has been prepared to provide offsite noticing for the Oasis Cleaners site based on the recent groundwater sampling results of offsite wells.

Subtask 2 – Groundwater Sampling: No Changes

Subtask 3 – Noticing

Based on the results of the groundwater samples from offsite wells, offsite concentrations of PCE, TCE, cis-1,2-DCE and VC were detected above the GCTLs. As discussed in the FDEP Site

Review Meeting, based on the results, noticing should be initiated with the new groundwater data

(attached). PCE, TCE, cis-1,2-DCE and VC were detected in wells located on the Gardenwood

Apartments property, and VC was reported in a well sampled at the PRP Bradenton Fuel Oil site.

Both properties are located downgradient of the former Oasis Cleaners.

The Noticing Package will be prepared based on the analytical results to include the preparation of maps identifying impacted properties, the generation of plume maps, completion of the

Noticing Table, and the Initial Notice Forms.

Noticing documents will be prepared and submitted within a week of approval of the scope of work and should be finalized by June 20, 2025.

APTIM proposes to perform this scope of work in accordance with the terms and conditions of contract No. HW689 executed between Florida Department of Environmental Protection and

APTIM Environmental & Infrastructure, LLC. APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification.
