About this file

This document is a groundwater monitoring report by Stantec Consulting Services for the Casselberry Police Department located at 4195 US Highway 17-92 in Seminole County, Florida. The report details concentrations of isopropylbenzene, ethylbenzene, and naphthalene in groundwater across multiple monitoring wells (MW-1 through MW-18) sampled in June 2023. The map illustrates the spatial distribution of chemical concentrations using color-coded isopleth lines, with specific concentration measurements noted for each monitoring well.

The document provides technical environmental data showing varying levels of chemical concentrations relative to groundwater guidance target concentrations (GCTL). For instance, different wells exhibit varying levels of isopropylbenzene (ranging from 0.22 to 8.4 µg/L), ethylbenzene (0.36 to 300 µg/L), and naphthalene (1.0 to 212 µg/L). A proposed institutional control (IC) boundary is marked in red, suggesting potential remediation or monitoring zone. The site is mapped with precise geographical references, including Melody Lane and Highway 17-92, and includes a scale and directional orientation.
