> Solicitation: SERDP Proposals for FY 23 Funding
purple divider

The Department of Defense's (DoD) Strategic Environmental Research and Development Program (SERDP) is seeking to fund environmental research and development proposals. SERDP is DoD's environmental science and technology program, planned and executed in partnership with the Department of Energy and the Environmental Protection Agency, with participation by numerous other Federal and non-Federal organizations. The Program invests across the broad spectrum of basic and applied research, as well as advanced development. Proposals responding to the Fiscal Year (FY) 2023 Statements of Need (SONs) will be selected through a competitive process. Separate solicitations are available to Federal and non-Federal proposers. The Core SERDP Solicitation provides funding in varying amounts for multi-year projects. All Core Solicitation pre-proposals are due to SERDP January 6, 2022 by 2:00 p.m. ET. SERDP also will be funding environmental research and development through the SERDP Exploratory Development (SEED) Solicitation. The SEED Solicitation is designed to provide a limited amount of funding (not to exceed $250,000) for projects up to approximately one year in duration to investigate innovative approaches that entail high technical risk or require supporting data to provide proof of concept. This year, SERDP is requesting SEED proposals for the Munitions Response program area. The SONs and detailed instructions for each are available on the SERDP website. All SEED proposals are due March 10, 2022 by 2:00 p.m. ET. For more information and to apply, please visit

Ehrenfeld AML Pilot Reclamation/Recreation & Watershed Improvement Project - December 1, 2021, 1:00PM-3:00PM EST (18:00-20:00 GMT). Pennsylvania Department of Environmental Protection's Ehrenfeld AML Pilot Reclamation and Recreation & Watershed Improvement Project was awarded the 2020 OSM Abandoned Mine Land Reclamation Award. The 2020 Abandoned Mine Land Reclamation Awards honor the most exemplary AML reclamation projects in the nation each year. In this presentation, Patrick Webb of PA DEP's Bureau of Abandoned Mine Reclamation Pennsylvania will present details of this project. Approximately 70 acres of coal refuse piles located along the "Johnstown Path of the Flood Trail," posed multiple environmental threats to the area. Frequent erosion clogged an unnamed tributary to the Little Conemaugh River, as a result, highly acidic water leached into and subsequently impaired local streams, burning areas of refuse piles and degrading air quality for the residents. To address these hazards, Pennsylvania's AML Program removed the refuse piles, eliminated the surface burning conditions and improved the Little Conemaugh watershed. The reclamation project has resulted in new opportunities for recreation and tourism with the addition of a community park and safer walking trails.

ITRC Strategies for Preventing and Managing Harmful Cyanobacteria Blooms - December 2, 2021, 1:00PM-3:15PM EST (18:00-20:15 GMT). Cyanobacteria are microscopic, photosynthetic organisms that occur naturally in all aquatic systems but most often in freshwater systems. Under certain conditions, cyanobacteria can multiply and become very abundant, discoloring the water throughout a water body or accumulating at the surface. These occurrences are known as blooms. Cyanobacteria may produce potent toxins (cyanotoxins) that pose a threat to human health. They can also harm wildlife and domestic animals, aquatic ecosystems, and local economies by disrupting drinking water systems and source waters, recreational uses, commercial and recreational fishing, and property values. It is likely that continued population growth, land use change, increases in nutrient inputs to our waterways, and the warming climate will favor proliferation of these problematic species. Providing a range of practical approaches to minimize these blooms and their likely societal and wildlife effects is critical to our future vitality, health, and economic prosperity.

ITRC Optimizing Injection Strategies and In situ Remediation Performance - December 7, 2021, 1:00PM-3:15PM EST (18:00-20:15 GMT). ITRC developed the guidance: Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1) and this associated training course to identify challenges that may impede or limit remedy effectiveness and discuss the potential optimization strategies, and specific actions that can be pursued, to improve the performance of in situ remediation by: refining and evaluating remedial design site characterization data; selecting the correct amendment; choosing delivery methods for site-specific conditions; creating design specifications; conducting performance evaluations, and optimizing underperforming in situ remedies. The target audience for this guidance and training course is: environmental consultants, responsible parties, federal and state regulators, as well as community and tribal stakeholders. This training will support users in efficiently and confidently applying the guidance at their remediation sites. An optimization case study is shared to illustrate the use of the associated guidance document. For more information and to register, see or

Superfund Quality and Sample Support (QSS) Pre-Solicitation Webinar - December 8, 2021, 1:00PM-3:15PM EST (18:00-20:15 GMT). The webinar will provide a technical overview of the procurement and respond to industry questions regarding the Performance Work Statement (PWS) and upcoming Request for Proposal (RFP). General contract information will also be presented. The QSS contractor shall perform Contract Laboratory Program (CLP) sample scheduling and tracking, analytical chemistry data review/assessment, invoice preparation, and reporting in a production environment; administrative, cost recovery, and analytical services support; quality assurance technical support; and information systems operations, maintenance, development, and security. The NAICS code for the QSS procurement is 541611 - Administrative Management and General Management Consulting Services. Please submit QSS PWS and RFP questions to EPA Contracting Officer Ross Miller ( and Contract Specialist Eric Langett ( For more information about the Superfund CLP, please visit For more information and to register, see

Research Brief 323: New Passive Sampling Device for PFAS. Researchers from the NIEHS Superfund Research Program (SRP)-funded centers at the University of Rhode Island (URI) and Brown University developed a new type of passive sampling device for per- and polyfluoroalkyl substances (PFAS). Their new tool overcomes many limitations to traditional approaches, such as detecting short-chain PFAS and low concentrations of the chemicals in water. PFAS chemicals, a large group of compounds found in aqueous film-forming foams, used for fire suppression, and in everyday consumer products, are made up of a chain of linked carbon and fluorine atoms.
