BOSC Safe and Sustainable Water Resources Subcommittee Report | October 28-29, 2020

Introduction

The U.S. Environmental Protection Agency (EPA's) Board of Scientific Counselors (BOSC) Safe and
Sustainable Water Resources (SSWR) Subcommittee appreciates the opportunity to provide input on
planned research products. The Subcommittee met October 28-29, 2020, November 17, 2020, and
December 2, 2020 to review the initial progress on implementation of the fiscal years (FY) 2019—2022
SSWR Strategic Research Action Plan (StRAP). The Subcommittee understands that the products are at
an early stage and recognizes the need for time and flexibility to carry out research during the
Coronavirus Disease 2019 (COVID-19) pandemic. The Subcommittee appreciates the creative efforts to
continue working to the extent possible from remote locations.

Charge Questions and Context

The SSWR Subcommittee was charged with addressing a series of questions about the SSWR Research

Program. Charge questions were as follows:

Q.1: Progress towards characterizing microplastics in the environment and uncertainties about their
potential environmental health effects requires reliable and consistent methods. SSWR is
conducting research to develop and standardize collection, extraction, identification and
quantification methods for microplastics. Based on the progress and results to date, what
suggestion(s) or recommendation(s) does the Subcommittee offer on research into addressing the
uncertainties and challenges associated with the Agency's efforts to develop reliable and consistent
microplastics analytical methods? [Research Area 1, Output 4]

Q.2: Existing geospatial datasets are often limited with respect to mapping rivers, streams, and
wetlands with the degree of accuracy and at the resolution needed to support federal, state, tribal,
and local water management decisions, including identifying "waters of the United States" subject
to Clean Water Act jurisdiction. SSWR is leveraging existing interagency partnerships to improve the
accuracy and application of geospatial data for mapping aquatic resources nationally. What
suggestion(s) or recommendation(s) does the Subcommittee offer on further identifying emerging
technologies, methodologies, and datasets to improve aquatic resource mapping tools and their
application for federal, state and local water management decisions? [Research Area 2, Output 1]

Q.3: To help reduce health risks associated with exposure to fecal contaminants in recreational
waters, SSWR is conducting research to strengthen the scientific basis of existing, and to advance
new, fecal contaminant detection methods, source tracking, predictive tools, and health effects
assessments that contribute to human health recreational water quality criteria programs. As the
research progresses, what suggestion(s) or recommendation(s) does the Subcommittee offer on
continuing to identify and conduct research of greatest importance to advancing human health
protection from fecal contaminants in recreational waters? [Research Area 3, Output 1]

The responses of the SSWR Subcommittee to the charge questions are contained in the following section.

Subcommittee Responses to Charge Questions

Charge Question 1

Q.1: Progress towards characterizing microplastics in the environment and uncertainties about
their potential environmental health effects requires reliable and consistent methods. SSWR is
conducting research to develop and standardize collection, extraction, identification and
quantification methods for microplastics. Based on the progress and results to date, what
suggestion(s) or recommendation(s) does the Subcommittee offer on research into addressing
the uncertainties and challenges associated with the Agency's efforts to develop reliable and
consistent microplastics analytical methods? [Research Area 1, Output 4]

Narrative

Numerous recent studies have documented the pervasiveness of microplastics, which EPA's Office of
Research and Development (ORD) defines as particles 5mm-l nm1, in the environment that may lead to
human exposure through inhalation and ingestion. Researchers throughout the world are working to build
a foundational understanding of the sources, transport routes, overall fate, and health impacts of
microplastics. Science professionals worldwide commend SSWR for entering this field, but EPA is late to
start researching and their investments must be selective to ensure they complement, rather than
duplicate, the research that other institutions are already undertaking. The research SSWR is conducting
achieves that goal.

SSWR's initial strategy focuses on measurements, which the Subcommittee believes is well-advised.
Current limitations in method harmonization, and quality assurance of those methods, will prevent or
hinder progress in understanding the effects of microplastics in the environment.

While there are several international efforts to achieve microplastic method standardization, SSWR has
appropriately identified three niches that are relatively understudied, and for which they can effectively
address gaps in the field. The first of those is measurement methods for microplastics in sediments. Most
ongoing work is focused on measurements in aqueous media. Sediments present a challenge because of
the additional step needed to separate plastics from the sediment before researchers can perform the
measurements. This is a particularly appropriate activity for SSWR because EPA runs the National Coastal
Condition Assessment, a national program that assesses that ecological condition of coastal aquatic
resources, including sediments. This provides a natural implementation outlet for this product.

The second methodological research area is nanoplastics, which is another wise choice. Unlike
microplastic measurements, which have many investigators, there are few groups working on
nanoplastics measurement methods, despite increasing research that point to the toxicological nature of
these smaller particles. ORD is scientifically well-positioned to implement this research, given their history
in assessing non-plastic nanotechnology.

The third research area is exploring cheaper methods that can serve as a prescreening tool to determine
whether or not implementing more expensive methods yielding information on shape and chemical
composition is warranted. In particular, their proposal to investigate the combustion alternative
treatment for microplastics in the environment (CATME) method for rapid determination of total plastics
in sediments shows great promise. Such prescreening techniques, if successful, will have many
applications. For instance, more frequent, cost-effective screening of drinking water would help

2

management groups focus and prioritize geographies or water sources that need additional treatment.
Simplified methods would also allow volunteer groups to contribute to the knowledge base. This is
another part of the measurement field that is relatively understudied, and to which SSWR could make a
substantial contribution.

Measurement methods to characterize microplastics is the appropriate starting point. SSWR should begin
work now towards developing a strategy for incorporating both environmental and human health effects
into the next StRAP. Health and toxicological effects can vary by particle size, shape, and composition, as
well as potential pathways of exposure. Consequently, developing a research framework on those micro
or nanoplastics that have the greatest potential for adverse environmental and health outcomes is critical
in tandem with methodological development.

Strengths

SSWR has identified measurement method niches which are understudied and for which they have
competencies that make them the right group to pursue those research lines.

BOSC commends SSWR for forming partnerships to achieve this mission. In particular, their work through
the Regional Applied Research Effort (RARE), a program that responds to the high-priority research needs
of EPA regional offices, has helped connect them with the State of California, which is scheduled to
become the first state to begin requiring routine monitoring of microplastics. Moreover, their partnership
with the American Society for Testing and Materials facilitates collaboration with other researchers who
are working to standardize measurement methods.

Suggestions

Continue investment in the three measurement niches as proposed. These are well-thought out and will
make valuable contributions to the field. SSWR's capacity-building investments to focus on producing
quality assurance and laboratory accreditation guidelines impressed the Subcommittee.

Recommendations

The Subcommittee offers the following recommendation to support the relevant Agency priorities:

Recommendation 1.1: Measurement methods to characterize microplastics is the appropriate
starting point. SSWR should begin work now towards developing a strategy for incorporating both
environmental and human health effects into the next StRAP.

Charge Question 2

Q.2: Existing geospatial datasets are often limited with respect to mapping rivers, streams, and
wetlands with the degree of accuracy and at the resolution needed to support federal, state,
tribal, and local water management decisions, including identifying "waters of the United States"
subject to Clean Water Act jurisdiction. SSWR is leveraging existing interagency partnerships to
improve the accuracy and application of geospatial data for mapping aquatic resources nationally.

and their application for federal, state and local water management decisions? [Research Area 2,
Output 1]

Narrative

SSWR is responding to the needs of EPA's Office of Water (OW) and the Army Corps of Engineers (USACE)
to identify the jurisdictional Waters of the United States, particularly with respect to the challenges
associated with identifying headwater streams (ephemeral and intermittent) and adjacent wetlands
connected to jurisdictional rivers under "normal" flow (i.e., a typical year as defined in the Navigable
Waters Protection Rule). The Agency is participating in an interagency collaboration with other partners,
including USACE, the United States Geological Survey (USGS), and the United States Fish and Wildlife
Service (USFWS) to discuss the uses, strengths and limitations of existing data such as the National
Hydrography Datasets (NHD) and National Wetland Inventory (NWI) and to recommend possible
improvements to those data sets. The goal of SSWR's research effort is to improve upon the classification
of jurisdictional waters in areas that cannot be mapped accurately using existing data sources. This effort
focuses on use of high-resolution imagery, topographic data, and various types of models distributed
across multiple geographic areas that represent a particular challenge for mapping using existing tools.
SSWR's effort is concentrated on case study watersheds with existing high-resolution data and modeling
tools, with the expectation that tools, and approaches developed for these areas can be extrapolated to
other regions.

Strengths

The Agency is to be commended for its participation in interagency efforts (e.g., with USACE, USFWS, and
USGS) to identify strategies and tools for mapping jurisdictional waters, especially with a focus on filling
gaps, and addressing known deficiencies in regional data sources such as NWI and NHD. In addition, the
Agency has conducted a comprehensive literature review and data assessment to identify specific
areas for which there is extensive high-resolution data (including satellite imagery, light detection and
ranging [LIDAR]) as well as modeling tools (e.g., dynamic TOPMODEL). The group has identified a specific
gap in modeling approaches that can be used to predict the probability of riverine flooding that will lead
to overflow into adjacent wetlands.

Suggestions

The Agency is participating in interagency discussions regarding the use and enhancement of regional data
sets that could prove useful in mapping a large percentage of the jurisdictional waters. SSWR's research
effort seeks to fill the gap in areas that cannot be mapped using those existing data and tools. Additional
resources that might be explored include use of the models WetLandscape or PHyLiSS (McKenna et al.
2018), which was developed in the Prairie Pothole Region to predict wetland water levels. For mapping
adjacent wetlands under specific flow regimes, enhanced NWI (attributed with hydrogeomorphic
characteristics) might be useful. In addition, the Restorable Wetland Index maps based on topographic
and land cover characteristics (https://data.nrri.umn.edu/data/dataset/minnesota-restorable-wetland-
index) may be another useful starting point for refining wetland connectivity maps.

The SSWR effort is currently addressing three difficult landscape settings where existing mapping tools
are problematic. These efforts could be further focused and prioritized through more sustained
participation of USACE practitioners to help define the most urgent mapping issues (i.e., utilizing a co-
production model of research engagement).

BOSC Safe and Sustainable Water Resources Subcommittee Report | October 28-29, 2020

Narrowly defined, Charge Question 2 focuses on emerging technologies, methods and data sets that might
be used to refine estimates of locations of ephemeral and intermittent stream channels and to
identify potentially connected wetlands adjacent to jurisdictional rivers and streams. Each of these
represent distinct mapping challenges because they represent a gradient of conditions that are defined
by the physical structure of the landscape, a dynamic hydrologic regime, and antecedent moisture
conditions, creating difficulties in deriving a strict classification. Rather, the gradient of conditions that
lead to channel formation and wetland connectivity are more appropriately defined using a probability
approach (see Recommendation 2.1). The Subcommittee recognizes that translating the complex science
based on probabilities into discrete classifications requires both science and policy perspectives.

Specific Suggestions:

•	Because the existing regional datasets (e.g., NWI and NHD) are capable of accurately identifying
a large percentage of the jurisdictional waters, it is critical that these data be updated and
improved to the extent possible. Therefore, the Subcommittee encourages
continued participation in interagency efforts to refine the national datasets.

•	Prioritize development of high-resolution data and models that reduce uncertainty in estimates
of stream channel origins and the extent/frequency of connectivity of adjacent wetlands in areas
that represent the greatest need and threat, based on input from targeted end users (OW,
USACE).

•	The Subcommittee suggests that SSWR further engage USACE practitioners to better define gaps
in specific knowledge and tools, identify any existing working USACE methodologies/guidance,
and target case studies and methods development to problems that most urgently need solving.
The Subcommittee also suggests expanding stakeholder engagement, where it makes sense to do
so, with additional federal partners (e.g., the National Oceanic and Atmospheria Administration,
or NOAA) as well as academic partners that may assist in the refinement of hydrologic models to
predict probability of flooding in adjacent wetlands under a range of flow regimes. The
Subcommittee also sees value in exploring partnership or knowledge-sharing through existing or
new networks with non-U.S. partners (e.g., scientific developments in the European Union to
support the new Water Framework and Floods Directives).

•	The Agency's current focus on high resolution models to explore case studies is anticipated to
provide valuable insight into site-specific hydrologic regimes. To make this information more
relevant nationally, the Subcommittee suggests that the Agency document and publish
methods and information needed for scaling the analytical processes to regional or national
models for future applications.

Recommendations

The Subcommittee offers the following recommendation to support the relevant Agency priorities:

Recommendation 2.1: Hydrologic regimes are characterized by a continuum rather than discrete
states. Therefore, the Subcommittee recommends the use of probabilistic metrics as a more accurate
way to represent "real world" hydrological conditions to inform discrete classification approaches. The
Subcommittee encourages the Agency to quantify uncertainties in both the underlying datasets as
well as their applications. This will help with research prioritization and provide a more quantitative
way to communicate success, progress, and key limitations among stakeholders.

Charge Question 3

Q.3: To help reduce health risks associated with exposure to fecal contaminants in recreational
waters, SSWR is conducting research to strengthen the scientific basis of existing, and to advance
new, fecal contaminant detection methods, source tracking, predictive tools, and health effects
assessments that contribute to human health recreational water quality criteria programs. As the
research progresses, what suggestion(s) or recommendation(s) does the Subcommittee offer on
continuing to identify and conduct research of greatest importance to advancing human health
protection from fecal contaminants in recreational waters? [Research Area 3, Output 1]

Narrative

Almost 100 million people swim in oceans, lakes, rivers, or streams each year, making it among the most
popular recreational activities in the United States. When those waters are contaminated, particularly
with human or animal feces, the associated pathogens are known to cause various health risks, including
gastrointestinal, respiratory, ear, eye, and skin infections. EPA has broad responsibilities to protect water
quality in recreational waters, and ORD has the charge to develop monitoring and assessment tools that
allow OW to achieve those goals.

ORD has a long history of successfully executing that role. They have been instrumental over the last two
decades in transitioning the Agency from the use of hundred-year-old culture-based measurement
methods to more modern genetic-based methods. These genetic methods are more reliable and more
rapid, shortening the time to measure from days to hours. They have also extended these molecular
techniques to use genetic signatures as a means of source identification, allowing managers to
differentiate whether the fecal contamination at a site originated from human or animal sources. Finally,
ORD has conducted the epidemiological studies that produce health-risk relationships for these new
methods, allowing the OW to set management guidelines that are appropriately protective of human
health.

The overall goal of this SSWR research area is to provide OW with information and tools needed for
establishing and updating criteria - including recreational water quality criteria, future updates of human
health criteria, and future revisions to aquatic life criteria. Charge Question 3 asked the Subcommittee to
focus specifically on work with data and innovative tools to advance public health protection from
microbial contaminants in surface waters. In their presentation to the Subcommittee, SSWR researchers
described a strong portfolio of research, including studies to enhance the performance of molecular
methods for existing indicators, development of new indicators, and expansion of microbial source

6


-------
BOSC Safe and Sustainable Water Resources Subcommittee Report | October 28-29, 2020

identification techniques. In addition, they described studies to assess the prevalence of antimicrobial
resistance to evaluate whether that is an important area for EPA to focus, and new forecast modeling
techniques that allow for predictions of water quality issues at a site even before the physical
measurements are made. The Subcommittee endorses all these research areas as appropriate to ORD and
of value to the nation.

Strengths

The Subcommittee is impressed by the research group that SSWR has assembled to address this topical
area and their accomplishments to date. There is no other research group in the world that is ahead of
them technically in this field. More importantly, they have successfully transitioned their work from the
laboratory to practice, as OW has promulgated new water quality criteria and promoted new associated
assessment techniques based on their research.

One of the key means SSWR has employed to achieve that success is through strategic partnerships, which
they emphasized in their presentation, and for which they should be commended. Some of those
partnerships are with other research institutions, particularly with academia, as they draw the best minds
in the nation to help them address their research objectives. The success of those partnerships is reflected
in the large number of collaborative publications with other institutions. However, their emphasis on
partnership also extends to working closely with end-users, such as states and tribes. Ultimately, OW is
more likely to make use of their products when there is consensus among the user community that these
tools can be implementable by the typical practitioner and add real value to the management process. By
working with the local community to employ those tools in demonstration programs in various
geographies, SSWR has been successful in creating interest and an awareness of these state-of-the-art
techniques.

The molecular tools that SSWR has developed have gained widespread traction in the user community.
However, there does not yet exist an agreed-upon means for assessing whether the techniques are being
properly utilized at the wide array of public and private laboratories that are now implementing them. As
their use transitions from exploratory public health warning systems to regulatory applications, there is a
need for programs, such as the National Environmental Laboratory Accreditation Program, to establish
and implement laboratory accreditation protocols for genetic-based measurement methods. The
development of a certified reference DNA material will be an important step in that direction. To the
extent possible, SSWR is encouraged to support efforts by the National Institute of Standards and
Technology or private organizations to create a certified reference DNA material.

While the Subcommittee feels that all of the research that SSWR has proposed is appropriate to the
Agency, the Subcommittee concluded the research focus that has the most opportunity for impact is the
further development of methods for the detection and quantification of coliphages as indicators of fecal
contamination in surface waters. Coliphage has some potential advantages over current fecal indicator
bacteria that are the focus of present water quality criteria. It may be less prone to false signals from
regrowth in the environment and can more closely mimic the survival of some pathogenic viruses after
disinfection. OW has suggested that they are interested in potentially adding coliphage as an additional
water quality criteria indicator. This potential improvement in monitoring, and the renewed interest by
OW, provides a tremendous opportunity for SSWR to impact the direction of the Agency's water quality
criteria and, again, successfully transition from research to application.

Suggestions

7


-------
BOSC Safe and Sustainable Water Resources Subcommittee Report | October 28-29, 2020

One of the challenges with the use of genetic measurement techniques is that genetic fragments can
persist in the water column long after the viability of the targets they represent has faded. Use of these
tools would benefit from a better understanding of the relative survival of the pathogens and the genetic
material that is now being quantified.

Regrowth in the environment of the indicators EPA uses can provide a false positive signal about the
presence of fecal contamination. SSWR should help improve understanding of this regrowth process, such
as what moisture, temperature and nutrients conditions cause such regrowth. Concern related to
source(s) and causes of microbial blooms affecting recreational waters are explored and would
complement other forensic details gathered when such events are investigated.

Recommendations

The Subcommittee offers the following recommendation to support the relevant Agency priorities:

Recommendation 3.1: The Subcommittee was charged with identifying the research of greatest
importance to advancing human health protection from fecal contaminants in recreational waters,
and it feels that while all of the research SSWR has proposed is appropriate, the research focus that
has the most significant opportunity for impact and should be prioritized is the further development
of methods for the detection and quantification of coliphages as indicators of fecal contamination in
surface waters.
