A. Introduction

Per- and polyfluoroalkyl substances (PFAS) are long-lasting chemicals that are widely used in an array of consumer, commercial, and industrial products. Due to widespread use and persistence in the environment, PFAS are commonly found in the water supply, remaining intact even after conventional water treatment. There is evidence that continued exposure to certain PFAS, even at low levels, can cause harmful health effects [1]. Measuring PFAS at low levels is a challenge with current analytical methods. In addition, PFAS treatment is incredibly difficult, as traditional chemical and biological methods often cannot degrade PFAS or produce PFAS-laden waste. This is especially important for rural and underserved communities1, where centralized water treatment facilities with trained operating and maintenance personnel are often unavailable or unaffordable. Rural communities also face barriers to frequent and rapid PFAS monitoring due to the challenges of transporting samples to a laboratory from remote locations.

Advances in nanoscience and nanotechnology have the potential to address the major challenges of conventional technology for the detection and treatment of PFAS-contaminated waters.

Nanoparticles have been introduced for the detection and remediation of a wide range of contaminants in different matrices [2,3]. Because of their unique properties, nanomaterials have enabled advances in sensor design such as miniaturization, portability, and rapid signal response times [4]. Nanomaterial-enabled sensors are being designed for efficiency, flexibility, and multipollutant sensing applications. Nanotechnology may help to build better environmental sensors by reducing cost, improving efficiency and increasing selectivity [5]. In addition to detection and monitoring, nanotechnology can also be used in the sequestration and degradation

1 For purposes of this competition, “underserved communities” refers to populations sharing a particular characteristic, as well as geographic communities, that have been systematically denied a full opportunity to participate equitably in aspects of economic, social, and civic life.

‘Equity’ means the consistent and systematic fair, just, and impartial treatment of all individuals, including those who belong to underserved communities. Underserved communities may include people/communities of color, the elderly, children, and those who have pre-existing medical conditions.

https://www.epa.gov/research-grants/research-funding-opportunities https://www.epa.gov/research-grants/research-grant-areas of pollutants. Nanomaterials have advantages to conventional treatment methods, such as smaller size, larger specific surface area, and are easily manipulated and dispersed in water [6].

The growing focus on removing low levels of PFAS contamination from drinking water supplies has produced several PFAS-removal approaches. However, the carbon-fluorine (C-F) bond in PFAS is extremely strong, making complete destruction difficult, and there are uncertainties around the effectiveness of traditional destruction technologies (e.g., thermal treatment) for PFAS. The next generation of high-performance separation and degradation technologies are needed for the safe and cost-effective removal and destruction of PFAS.

This funding opportunity is soliciting research to develop and demonstrate nanosensor technology with functionalized catalysts that have the potential to degrade selected contaminants in addition to detecting and monitoring pollutants. Specifically, EPA is seeking proposals that use nanotechnology to detect, monitor, and degrade PFAS in groundwater or surface water that may be used as drinking water sources.

The Science to Achieve Results (STAR) Program’s goal is to stimulate and support scientific and engineering research that advances EPA’s mission to protect human health and the environment.

It is a competitive, peer-reviewed, extramural research program that provides access to the nation’s best scientists and engineers in academic and other nonprofit research institutions.

STAR funds research on the environmental and public health effects of air quality, environmental changes, water quality and quantity, hazardous waste, toxic substances, and pesticides.

The EPA anticipates funding approximately one award under this funding opportunity up to $1,500,000 per award.

EPA recognizes that it is important to engage all available minds to address the environmental challenges facing the Nation. EPA seeks to expand the environmental conversation by including members of communities which may have not previously participated in such dialogues to participate in EPA programs.

B. Background, Goals, and Objectives

The Interagency Subcommittee on Nanoscale Science, Engineering and Technology (NSET) of the Office of Science and Technology Policy (OSTP) defined nanotechnology as “the understanding and control of matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications” [2]. Nanotechnology research and development involves imaging, measuring, modeling, and manipulating matter at this scale.

Matter can exhibit unusual physical, chemical, and biological properties at the nanoscale, differing from the properties of bulk materials and molecules. At the nanoscale, some materials are more robust, have different magnetic properties, or are better at conducting heat or electricity than other forms or sizes of the same material. They may become more chemically reactive, use light energy more effectively in catalysis, or change color as their size or structure is altered [2, 3]. Consequently, there has been great interest to use engineered nanomaterials for environmental sensing and catalysis. In particular, the properties of nanosensors and nanomaterials have the potential to provide quick, reliable, and sensitive detection and catalytic destruction of PFAS.

PFAS are a group of man-made chemicals that are widely used for their nonstick, water-resistant, and stain-resistant properties. These chemical properties also mean they persist in the environment and can accumulate in the human body. Some PFAS have been found to be harmful to human health and the environment, and EPA is taking several actions to address PFAS, including actions on Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS), two of the most commonly studied and longest used PFAS [1]. Short chain PFAS, such as GenX chemicals, that were introduced to replace the legacy longer-chain compounds are even more difficult to sequester from contaminated sources. Thus, there is a great need for extremely low detection limits and removal technologies to further protect human health. EPA has prioritized PFAS research in the past decade and has made many improvements towards how stakeholders can detect, monitor, and remove PFAS from drinking water sources.

Current technologies for detecting and quantifying PFAS, typically liquid chromatography/tandem mass spectrometry (LC/MS/MS) [7], are time-consuming, expensive, https://msiexchange.nasa.gov/institutions?qp%5B0%5D=categories__name&qo%5B0%5D=is&qv%5B0%5D=Asian%20American%20and%20Native%20American%20Pacific%20Islander%20Serving%20Institutions https://msiexchange.nasa.gov/institutions?qp%5B0%5D=categories__name&qo%5B0%5D=is&qv%5B0%5D=Predominantly%20Black%20Institutions https://msiexchange.nasa.gov/institutions?qp%5B0%5D=categories__name&qo%5B0%5D=is&qv%5B0%5D=Native%20American-Serving%20Non-Tribal%20Institutions https://msiexchange.nasa.gov/institutions?qp%5B0%5D=categories__name&qo%5B0%5D=is&qv%5B0%5D=Native%20American-Serving%20Non-Tribal%20Institutions https://msiexchange.nasa.gov/institutions?qp%5B0%5D=categories__name&qo%5B0%5D=is&qv%5B0%5D=Alaska%20Native%20and%20Native%20Hawaiian and performed off-site in specialized laboratories. Nanosensors present an opportunity for quick, less expensive, reliable, and on-site detection of PFAS in different water matrices [8, 9,10, 11].

The high surface to volume ratios and flexible surface functionalization makes nanomaterials highly sensitive to changes in surface chemistry, thus allowing nanotechnology-enabled sensors to achieve extremely low detection limits [12, 13, 14, 15]. While efforts are being made to improve the specificity and sensitivity of environmental sensors at low detection levels, questions of assay selectivity and sensitivity in complex matrices remain [12].

There are many desired characteristics of environmental sensors, including operational convenience (portability, functionality at room temperature), high-resolution monitoring for big data applications, realtime measurements, rapid response and processing time, long-term stability, and reproducibility [16]. The robust and user-friendly design of sensors are essential for stakeholders such as state and local governments, rural and underserved communities, and Tribes to monitor their environment. Nanotechnology can help environmental sensors meet the needs described above, which are difficult to attain with traditional lab-based analyses and provide a tool for real-world implementation of sensors that are rapid, reliable, and accessible to communities.

PFAS have been referred to as “forever chemicals” because of their resistance to most biological and chemical degradation mechanisms. The strong C-F bonds that give PFAS their desirable properties also make these compounds resistant to degradation. Conventional treatment of PFAS-contaminated water is focused on removal techniques like adsorption, ion exchange, and membrane filtration that are not focused on destruction. Adsorbents or membrane-based separation processes create PFAS-contaminated solid or liquid waste streams that must be managed, but do not address how to degrade these persistent pollutants. There is a need for degradation approaches that break C-F bonds, resulting in full mineralization of PFAS. Previous studies have shown nanomaterials to achieve destruction of the carbon-fluorine bond through mineralization, which creates non-harmful by-products [17]. Portable, reusable, and ecofriendly nanotechnology-enabled PFAS degradation systems can reduce the need for expensive centralized water treatment facilities and for energy-consuming treatments of PFAS-contaminated waste.

E. Specific Research Areas of Interest

EPA is interested in a holistic approach for detecting, monitoring, and degrading PFAS in groundwater or surface water that may be used as drinking water sources. Nanosensors to detect and monitor PFAS should be integrated with a nanotechnology-based treatment mineralization process focused on destruction of the C-F bond. Projects should make a case for a sensing solution as well as a degradation solution that does not create harmful by-products.

The specific PFAS studied should be in EPA’s Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) [18]. The relevant PFAS are listed below:

• 11-choroeicosafluoro-3-oxaundecane-1-sulfonic acid (11Cl-PF3OUdS)

• 9-chlorohexadecafluoro-3-oxanonane-1-sulfonic acid (9Cl-PF3ONS)

• Perfluorotridecanoic acid (PFTrDA)

The type of nanomaterial (e.g., carbon-based, metal oxides, quantum dots), other recognition element (e.g., antibodies, enzymes, DNA), and signal transduction method (e.g., optical, electrochemical, magnetic) that make up the nanosensor are at the discretion of the applicant.

Projects may use different nanoparticles for the detection/monitoring and degradation portions of the project but should focus on the same PFAS.

EPA is seeking projects with expected results that can be practically applied in real-world settings and potentially transform environmental monitoring and management, not proof-of concept or bench-scale projects. While this funding opportunity solicits original nanotechnology projects, applicants should not propose a new prototype but rather a system based on an existing prototype that can be demonstrated to detect and degrade contaminants in the relevant environment. Assessment with Technology Readiness Levels (TRL) is a formal approach to evaluate the maturity of a technology and has been widely adopted by the industry to manage technology development [19, 20, 21]. There are three main stages of development. The first stage (technology with TRL 1-3) involves designing a feasibility prototype based on an invention. The second stage (technology with TRL 4-6) requires prototype development, aiming to deliver the α-prototype, that embeds all the essential features in the final product. The final stage (technology with TRL 7-9) involves commercial product development [20]. See Table 23 in the report titled Development of a Disposable AChE Sensor for As(III) and Field Analysis Method;

Tests with Groundwater Samples from Shepley’s Hill Landfill for characteristics, activities, and deliverables typical of TRL for sensor development. This funding opportunity is seeking nanotechnology that is ready to be validated and demonstrated in the lab or relevant environment, equivalent to a TRL of 4-6. Applications should clearly define the TRL of their technology. Projects with a TRL of 1-3 may not be rated as highly as those with a TRL of 4-6.

(NOTE: STAR grant funding must be used for research and cannot be used for commercialization or for-profit initiatives such as business creation. Therefore, this solicitation does not support projects with a TRL of 7-9.)

https://cfpub.epa.gov/si/si_public_record_Report.cfm?dirEntryId=352598&Lab=CESER https://cfpub.epa.gov/si/si_public_record_Report.cfm?dirEntryId=352598&Lab=CESER

This funding opportunity solicits applications that address both of the following research areas. Applications that only address one research area may not be rated as highly as those that address both.

Research Area 1: Develop and demonstrate nanosensor technology to detect and monitor PFAS in drinking water sources The proposed nanotechnology should specifically detect and monitor PFAS in groundwater or surface water that may be used as drinking water sources. Nanosensors may include the following characteristics:

• Have a broad range of capabilities for the measurement of PFAS in water.

• Be reliable and easy to operate.

• Function in a range of chemical concentrations relevant to human health.

• Demonstrate high sensitivity and selectivity with detection limit values on par with the minimum reporting levels in UCMR 5.

• Detect PFAS in the environment at or near to real time.

• Function under conditions normally associated with real environmental matrices.

• Provide temporal data for the location and time of measurement.

• Collect information on fate and transport of PFAS across a large distance.

• Communicate wirelessly to users.

• Have potential to be integrated into a comprehensive monitoring system.

Research Area 2: Develop and demonstrate nanosensor technology with functionalized catalysts to degrade PFAS The proposed nanotechnology should degrade PFAS through chemical reactions that render the pollutants harmless and create non-harmful by-products. Applications should demonstrate enhanced performance of the nanotechnology-enabled catalysis through improved efficiency (speed and completeness of the reaction) and sustainability (input and by-products of the reaction).

G. Special Requirements

It is EPA Policy to ensure that the results of EPA-funded extramural scientific research are accessible to the public to the greatest extent feasible consistent with applicable law; policies and Orders; the Agency’s mission; resource constraints; and U.S. national, homeland and economic security. This entails maximizing, at no charge, access by the public to peer-reviewed, scientific research journal publications or associated author manuscripts, and their underlying digital research data, created in whole or in part with EPA funds, while protecting personal privacy;

recognizing proprietary interests, confidential business information, and intellectual property rights; and avoiding significant negative impact on intellectual property rights, innovation, and U.S. competitiveness.

Applications submitted under this announcement should include a Scientific Data Management Plan (SDMP) that addresses public access to EPA-funded scientific research data. See the SDMP clause in Section IV for details on the content of an SDMP. Applicants will also be asked to provide past performance information on whether journal publications or associated author manuscripts, and the associated underlying scientific research data and metadata, under prior assistance agreements were made publicly accessible. These items will be evaluated prior to award.

Reasonable, necessary and allocable costs for data management and public access may be included in extramural research applications and detailed in the budget justification described in Section IV.

Agency policy and ethical considerations prevent EPA technical staff and managers from providing applicants with information that may create an unfair competitive advantage.

Consequently, EPA employees will not review, comment, advise, and/or provide technical assistance to applicants preparing applications in response to EPA funding opportunities. EPA employees cannot endorse any specific application.

Multiple Investigator applications may be submitted as: (1) a single Lead Principal Investigator (PI) application with Co-PI(s) or (2) a Multiple PI application (with a single Contact PI). If you choose to submit a Multiple PI application, you must follow the specific instructions provided in Sections IV and V of this funding opportunity. For further information, please see the EPA Implementation Plan for Policy on Multiple Principal Investigators (Research Grants Guidance and Policies).

This solicitation provides the opportunity for the submission of applications for projects that may involve human subjects research. All applications should include a Human Subjects Research Statement (HSRS; described in Section IV.C.5.iii.c of this solicitation). If the project involves human subjects research, it will be subject to an additional level of review prior to funding decisions being made as described in Sections V.D and V.G of this solicitation.

These awards may involve the collection of “Geospatial Information,” which includes information that identifies the geographic location and characteristics of natural or constructed features or boundaries on the Earth or applications, tools, and hardware associated with the generation, maintenance, or distribution of such information. This information may be derived from, among other things, a Geographic Positioning System (GPS), remote sensing, mapping, charting, and surveying technologies, or statistical data.

H. Additional Provisions for Applicants Incorporated into the Solicitation

Additional provisions that apply to sections III, IV, V, and VI of this solicitation and/or awards made under this solicitation, can be found at EPA Solicitation Clauses. These provisions are important for applying to this solicitation and applicants must review them when preparing applications for this solicitation. If you are unable to access these provisions electronically at the website above, please contact the EPA point of contact listed in this solicitation (usually in Section VII) to obtain the provisions.

II. AWARD INFORMATION

It is anticipated that a total of approximately $1,500,000 will be awarded under this announcement, depending on the availability of funds, quality of applications received, and other applicable considerations. The EPA anticipates funding approximately one award under this funding opportunity. Requests for amounts in excess of a total of $1,500,000 per award, including direct and indirect costs, will not be considered. The total project period requested in an application submitted for this funding opportunity may not exceed three years.

The EPA reserves the right to reject all applications and make no awards under this funding opportunity. The EPA reserves the right to make additional awards under this announcement, consistent with Agency policy, if additional funding becomes available after the original selections are made. Any additional selections for awards will be made no later than six months after the original selection decisions.

In appropriate circumstances, EPA reserves the right to partially fund applications by funding discrete portions or phases of proposed projects. If EPA decides to partially fund an application, https://www.epa.gov/research-grants/research-grants-guidance-and-policies https://www.epa.gov/research-grants/research-grants-guidance-and-policies https://www.epa.gov/grants/epa-solicitation-clauses it will do so in a manner that does not prejudice any applicants or affect the basis upon which the application, or portion thereof, was evaluated and selected for award, and therefore maintains the integrity of the competition and selection process. Awards may be fully or incrementally funded, as appropriate, based on funding availability, satisfactory performance, and other applicable considerations.

EPA intends to award only grants under this announcement.

Under a grant, EPA scientists and engineers will not be substantially involved in the execution of the research. However, EPA encourages interaction between its own laboratory scientists and grant Principal Investigators after the award of an EPA grant for the sole purpose of exchanging information in research areas of common interest that may add value to their respective research activities. This interaction must be incidental rather than substantial to achieving the goals of the research under a grant. Interaction that is “incidental” does not involve resource commitments by

EPA.

III. ELIGIBILITY INFORMATION

Note: Additional provisions that apply to this section can be found at EPA Solicitation Clauses.

A. Eligible Applicants

Public and private nonprofit institutions/organizations, public and private institutions of higher education (IHEs), and hospitals located in the U.S. and its territories or possessions; state and local governments; Federally Recognized Indian Tribal Governments; and U.S. territories or possessions are eligible to apply. Profit-making firms and individuals are not eligible to apply.

Consistent with the definition of Nonprofit organization at 2 CFR § 200.1, the term nonprofit organization means any corporation, trust, association, cooperative, or other organization that is operated mainly for scientific, educational, service, charitable, or similar purpose in the public interest and is not organized primarily for profit; and uses net proceeds to maintain, improve, or expand the operation of the organization. The term includes tax-exempt nonprofit neighborhood and labor organizations. Note that 2 CFR § 200.1 specifically excludes Institutions of Higher Education from the definition of non-profit organization because they are separately defined in the regulation. While not considered to be a nonprofit organization(s) as defined by 2 CFR § 200.1, public or nonprofit Institutions of Higher Education are, nevertheless, eligible to submit applications under this funding opportunity. Hospitals operated by state, tribal, or local governments or that meet the definition of nonprofit at 2 CFR § 200.1 are also eligible to apply as nonprofits or as instrumentalities of the unit of government depending on the applicable law.

For-profit colleges, universities, trade schools, and hospitals are ineligible.

Nonprofit organizations that are not exempt from taxation under section 501 of the Internal Revenue Code must submit other forms of documentation of nonprofit status; such as certificates of incorporation as nonprofit under state or tribal law. Nonprofit organizations exempt from taxation under section 501(c)(4) of the Internal Revenue Code that lobby are not eligible for EPA funding as provided in the Lobbying Disclosure Act, 2 U.S.C. 1611.

Foreign governments, international organizations, and non-governmental international organizations/institutions are not eligible to apply.

National laboratories funded by Federal Agencies (Federally-Funded Research and Development Centers, “FFRDCs”) may not apply. FFRDC employees may cooperate or collaborate with eligible applicants within the limits imposed by applicable legislation and regulations. They may participate in planning, conducting, and analyzing the research directed by the applicant, but may not direct projects on behalf of the applicant organization. An award recipient may provide funds through its assistance agreement from the EPA to an FFRDC for research personnel, supplies, equipment, and other expenses directly related to the research.

Federal Agencies may not apply. Federal employees are not eligible to serve in a principal leadership role on an assistance agreement. Federal employees may not receive salaries or augment their Agency’s appropriations through awards made under this program unless authorized by law to receive such funding.

The applicant institution may enter into an agreement with a Federal Agency to purchase or utilize unique supplies or services unavailable in the private sector to the extent authorized by law. Examples are purchase of satellite data, chemical reference standards, analyses, or use of instrumentation or other facilities not available elsewhere. A written justification for federal involvement must be included in the application. In addition, an appropriate form of assurance that documents the commitment, such as a letter of intent from the Federal Agency involved, should be included.

Potential applicants who are uncertain of their eligibility should contact the Eligibility Contact listed under Section VII. Agency Contacts.

B. Cost sharing

Cost sharing is not required.

C. Other

All applications will be reviewed for eligibility and must meet the eligibility requirements described in Sections III.A., B., and C. to be considered eligible. Applicants deemed ineligible for funding consideration as a result of the threshold eligibility review will be notified within 15 calendar days of the ineligibility determination.

a. Applications must substantially comply with the application submission instructions and requirements set forth in Section IV of this solicitation or else they will be rejected. However, where a page limit is expressed in Section IV with respect to the application, or parts thereof, pages in excess of the page limitation will not be reviewed. Applicants are advised that readability is of paramount importance and should take precedence in application format, including selecting a legible font type and size for use in the application.

b. In addition, initial applications must be submitted through Grants.gov as stated in Section IV of this solicitation (except in the limited circumstances where another mode of submission is specifically allowed for as explained in Section IV) on or before the application submission deadline published in Section IV of this solicitation. Applicants are responsible for following the submission instructions in Section IV of this solicitation to ensure that their application is timely submitted. Please note that applicants experiencing technical issues with submitting through Grants.gov should follow the instructions provided in Section IV, which include both the requirement to contact Grants.gov and email a full application to EPA prior to the deadline.

c. Applications submitted outside of Grants.gov will be deemed ineligible without further consideration unless the applicant can clearly demonstrate that it was due to EPA mishandling or technical problems associated with Grants.gov or SAM.gov. An applicant’s failure to timely submit their application through Grants.gov because they did not timely or properly register in SAM.gov or Grants.gov will not be considered an acceptable reason to consider a submission outside of Grants.gov.

If an applicant submits more than one application under this announcement, each application must be submitted separately, and the scope of work proposed in each application must be significantly different from the other application(s) in order for them to all be deemed eligible. If applications are submitted with scopes of work that do not significantly differ, then EPA will only accept the most recently submitted application and all other applications will be deemed ineligible.

If an application is submitted that includes any ineligible tasks or activities, that portion of the application will be ineligible for funding and may, depending on the extent to which it affects the application, render the entire application ineligible for funding.

Also, applications exceeding the funding limits or project period described in Section II will be rejected without review. Further, applications that fail to demonstrate a public purpose of support or stimulation (e.g., by proposing research which primarily benefits a Federal program or provides a service for a Federal agency) will not be funded.
