One sediment core will be collected at the deepest point in the lake near the hypolimnetic aerator at a depth of around 9 m. The second core will be collected mid -lake from the boat launch in about 6 m of water and a third core will be collected in the southern end of the lake in about 3 m of water. Sediment core data will be used to calculate an aluminum dose to inactivate sediment mobile phosphorus. Sediment cores will be collected using a piston corer deployed from a boat. Sediment cores will be delivered to IEH Analytical Laboratory in Seattle, WA and sectioned by the laboratory into sections. Cores will be sectioned into 8 sample intervals: 0-2 cm, 2-4 cm, 4-6 cm, 6-10 cm, 10-15 cm, 15-20 cm, 20-30 cm, and 30- 50 cm. All sample intervals will be analyzed for total solids and water content, total phosphorus, total aluminum, total calcium, total iron, and the following phosphorus fractions: loosely -bound P, iron -bound P, organic P, biogenic P, aluminum -bound P, and calcium -bound P. IEH Analytical Laboratories will analyze the sediment cores for the specified parameters using appropriate methodology defined in a chain -of -custody record. IEH Analytical Laboratories will complete the analyses and submit a data report to Tetra Tech within 8 weeks of receipt of sediment cores. Tetra Tech will conduct a quality assurance review of the sediment data. The reviewed data will be tabulated in a spreadsheet database and presented graphically with comparisons to sediment data from other WA lakes. Deliverables; • Electronic copies of lap reports • Sediment core data and QA/QC review of core data for usability (will be included in Technical Memorandum as part of Task 2c) Assumptions: • The City of Kent and Tetra Tech mutually agree on the number and location of sediment cores. • Tetra Tech will provide 2 field staff as well as equipment to collect sediment cores. • IEH Analytical Laboratories will provide sediment data and lab reports within 8 weeks of receipt of cores.
