In Sustainable Phosphorus Alliance working groups, we partner to take action in initiatives that contribute to the mission of phosphorus sustainability. Participation in working groups is a benefit of membership. Contact us for more information on working groups.
Biosolids and Manure Task Force
The Biosolids and Manure Task Force undertook a comparative analysis of the federal and state regulations governing the land application of biosolids and manure in the US and plans to expand the analysis to Canada. That work yielded, GIS-P, our geographically-browsable data interface for state-by-state comparisons of regulatory regimes and contextualizing data.
Member organizations of the Sustainable Phosphorus Alliance and other invitees from industry and government contributed to the task force by providing oversight and feedback. Thank you to our Oversight Board members representing Kieser & Associates, Lystek International, Metropolitan Water Reclamation District of Greater Chicago, Mid-Atlantic Biosolids, National Association of Clean Water Agencies, National Milk Producers Federation, NEFCO, North East Biosolids & Residuals Association, Smithfield Foods, Synagro, US EPA, and Veolia.
Task Force Objectives
- To compile and compare all state and federal regulations related to biosolids and manure land applications
- To identify local variations in regulatory interpretations
- To produce an online tool that facilitates study of the data, now available here
Phosphorus Field-to-Watershed (PF2W) Modeling Workshop
One of the classic environmental management dilemmas is that we often understand and evaluate systems at large scales (watersheds, sub-basins), yet management of the landscape most often occurs at the field or even sub-field scale. In the Phosphorus Field-to-Watershed (PF2W) Modeling Workshop, we brought together practitioners to discuss how to dovetail existing in-field phosphorus measurements and modeled phosphorus pools. In August 2018, scientists and members of the Sustainable Phosphorus Alliance were invited to this workshop. That event yielded three action groups who are working on identified knowledge gaps, as described in our blog. Updates from these groups were presented at Phosphorus Forum 2019.Videos of the PF2W Modeling Workshop are available on YouTube.
