The purpose of the L-30 SMPP is to address seepage management along the L-30 Canal, as well as address seepage issues related to the onset of other Comprehensive Everglades Restoration Plan (CERP) projects within the next five years. The project is located west of Miami, near the intersection of Tamiami Trail (US 41) and Krome Ave (Route 997). The L-30 Canal mainly runs north-south but makes roughly a 45-degree southwesterly departure from Krome Ave until it intersects Tamiami Trail, forming what is commonly known as "the L-30 triangle."
ANAMAR was contracted by the U.S. Army Corps of Engineers, Jacksonville District to collect and analyze groundwater and surface water samples from three groundwater monitoring wells located on the L-30 levee and one surface water site located at the headwaters of S-335. Prior to proceeding with the field sampling effort, ANAMAR submitted a Field Sampling Plan (FSP), Quality Assurance Project Plan (QAPP), and Health and Safety Plan (HSP). These documents addressed all procedures for sampling, sample handling, storage, analysis, and safety issues.
Groundwater samples were analyzed for inorganic contaminants, primary organic contaminants, synthetic organic contaminants (pesticides and PCBs), radionuclide contaminants, microbiological contaminants, secondary drinking water standards, and miscellaneous groundwater parameters. Surface water samples were analyzed for nutrients, major ions, metals, trace metals, priority pollutants, and microbiological contaminants. The final report also detailed the investigation, sampling techniques, and methods. The information presented in the final report will be used to establish a pre-project screening of water quality conditions at the site.
