About this file

The document is a monitoring well concentration map prepared by Stantec Consulting Services for the Casselberry Police Department in Seminole County, Florida, dated June 2023. The map depicts groundwater monitoring data for three chemical compounds (isopropylbenzene, ethylbenzene, and naphthalene) across multiple monitoring wells (MW-1 through MW-18) located on and around the police department property at 4195 US Highway 17-92. The map includes concentration isopleths (contour lines) for each chemical, showing their geographic distribution and levels relative to groundwater guidance concentration to total levels (GCTL) standards.

The technical document provides detailed data for each monitoring well, including sampling dates (June 2023), chemical concentrations in μg/L, and spatial relationships. The map reveals varying concentration levels across different wells, with some wells showing concentrations above guidance levels. The red lines indicate a proposed institutional control (IC) boundary, suggesting potential environmental management or remediation strategies are being considered for the site. The document appears to be part of an environmental monitoring and assessment process for the Casselberry Police Department property, likely related to potential groundwater contamination investigation and management.
