Objective:
This project consists of four objectives, which will be accomplished following a two-track approach.
Track 1: PFAS characterization in samples from full-scale landfills and leachate treatment systems
Objective 1 – baseline characterization of PFAS occurrence and concentration in landfill samples
Objective 2 – detailed assessment of selected landfill sites and experimentation with leachate treatment
Track 2: Determine the sources of PFAS compounds in US domestic waste streams and landfill simulations
Objective 3 – measurement of leachable PFAS in waste streams with batch leaching tests
Objective 4 – measurement of PFAS through lysimeter studies using simulated waste streams.
Progress Summary:
During the first year of this project, we have completed tasks associated with Objectives 1 and 2 of the proposed research. We have collected leachate and environmental water samples (groundwater and storm water) from 37 landfill sites in Florida, as well as 1 site outside of Florida (Pennsylvania). We collected PFAS and physical-chemical parameter data for these samples. The detailed landfill leachate site assessment described in Objective 2 of the proposed work is currently underway, and we have collected repeat leachate samples from five Florida landfills. Due to Covid-19 impacts, waste composition studies have been postponed and tasks associated with Objectives 3 and 4 will be rescheduled for the end of the 2020 calendar year. Objectives 1 and 2 have been accelerated and will be completed earlier than expected.
Future Activities:
In Year 2 of this project, investigators will continue leachate treatment studies associated with Objective 2, and Objectives 3 and 4, beginning with waste composition studies proposed for the end of calendar year 2020 followed by the lysimeter construction in the fourth quarter.
