About this file

This document is a groundwater monitoring report prepared by Stantec Consulting Services Inc. for the Casselberry Police Department, located at 4195 US Highway 17-92 in Seminole County, Florida. The report, dated June 2023, focuses on measuring concentrations of isopropylbenzene, ethylbenzene, and naphthalene in groundwater across multiple monitoring wells (MW-1 through MW-18) on the property. The site map illustrates the sampling locations, concentration isopleths, and proposed institutional control (IC) boundary, with detailed measurements for each well recorded on the document.

The report provides technical environmental data showing concentration levels of chemical compounds in micrograms per liter (µg/L), comparing them against groundwater target cleanup levels (GCTL). Sampling was conducted on various dates in June 2023, with most wells sampled on 6/28/23. The concentration levels vary across different wells, with some exceeding established threshold limits for isopropylbenzene (0.8 µg/L), ethylbenzene (30 µg/L), and naphthalene (14 µg/L). The map includes a color-coded legend and scale to help visualize the spatial distribution of these chemical concentrations, which appears to be part of an environmental monitoring and potential remediation effort for the Casselberry Police Department site.
