Groundwater Monitoring Project

Beginning in the 3rd quarter of 2021, the contractor will sample the seventy (70) monitoring wells located on the subject sites on a quarterly basis for three (3) years. The sampling will be conducted under Florida Department of Environmental Protection, Standard Operating Procedures (FDEP-SOP001/01), FS-2200 for groundwater sampling. The sampling analysis will consist of chloride, pH, TDS, and turbidity. Samples are to be collected via peristaltic pump. A field sampling data sheet will be prepared for each well sampled that will include depth to water and a calculation of well volume for purging. One field equipment blank and one duplicate sample will be taken during each quarterly sampling round in order to meet Quality Assurance/Quality Control (QA/QC) requirements. Each sample will be analyzed by a state certified testing laboratory in accordance with the following: EPA Method 300 for dissolved chloride, EPA Method 150.1 for pH. EPA Method 160.1 for TDS, and EPA Method 180.1 for turbidity. A Chain of Custody form will be completed properly identifying sample locations, sample type, sampler, etc. Quarterly results will be reported in a cumulative table. Original copies of laboratory data and field sampling sheets will be attached to the quarterly report. The District requires the report be submitted within 15 days of completion of sampling. All reports will be submitted to the District in electronic format, not printed format. The District may also require specific standardized forms be used in reporting the well data which will be supplied.
