Recommendations of the On-Site Wastewater Treatment Systems Nitrogen Reduction Technology Expert Review Panel

This expert panel report, prepared by Tetra Tech (2014) evaluates on-site wastewater treatment system technologies and modifications that can reduce total nitrogen loads to the Chesapeake Bay watershed and recommends associated crediting approaches for inclusion in the Chesapeake Bay Model. It links nitrogen reduction credits to system design, installation, and operational practices, while also outlining verification considerations and emphasizing alkalinity control, improved data sharing, and the potential role of soil characteristics in refining future performance estimates.
