Re: Crossroads Square Shopping Center (ERIC_4625) 8102 Blanding Boulevard Jacksonville, Florida 32244 Task Assignment DC006B Subtask 3 Deliverable

Dear Ms. Fowler:

Environmental Consulting & Technology, Inc. (ECT) was issued Task Assignment DC006B on September 14, 2023, to perform annual natural attenuation monitoring (NAM) at the Crossroads Square Shopping Center. Annual NAM was performed on February 14, 2024, which consisted of collecting groundwater samples from seven monitoring wells for laboratory analysis. Purge water generated during NAM was containerized in one Florida Department of Transportation-approved 55-gallon drum which was sampled and temporarily left onsite as shown in the photograph below.

One sample of the investigation derived waste (IDW) was collected (ID: IDW-20240214) and analyzed for volatile organic halogens (VOHs) using U.S. Environmental Protection Agency Method 8260D.

Ms. Kelly Crain, FDEP Crossroads Square Shopping Plaza (ERIC_4625) April 22, 2024 ectinc.com

Results of the analysis document that the IDW was nonhazardous. The laboratory analytical report is included as Attachment 1.

On April 22, 2024, Erwin Remediation, Inc. (Erwin) arrived onsite to remove the drum for proper disposal and could not locate the drum. The photograph below provided by Erwin shows that the drum was not at its original location when they arrived onsite. The drum is presumed to have been stolen from the site.

Should you have any questions regarding this submittal, please contact the undersigned.

Sincerely, ENVIRONMENTAL CONSULTING & TECHNOLOGY, INC.

Leif E. Layton, Ph.D. Mark A. Culbreth, P.G Engineer Principal Scientist
