The Record of Decision (ROD) for the Site was issued by the NYSDEC in September 2020. The approved remedy for the Site includes a surface cover, institutional controls and dense non-aqueous phase liquid (DNAPL) recovery.

Beginning in April 2022, the Nassau Gas Works MGP Site has entered into the Pre-Design Investigation (PDI) phase of the project in which six recovery wells were installed in zones of potential DNAPL recovery. Recovery wells were installed at depths determined by the visual observations made during the soil boring stage. After installation, recovery wells were developed and gauged for the presence and thickness of DNAPL immediately prior to and after well development. Recovery wells will be monitored one day following development, one week following development, two weeks following development, then monthly for 6-months following development. A final PDI report will be prepared once the 6-month monitoring period is complete.
