FOREWORD
The U.S. Environmental Protection Agency (EPA) is charged by Congress with protecting the
Nation's land, air, and water resources. Under a mandate of national environmental laws, the
Agency strives to formulate and implement actions leading to a compatible balance between
human activities and the ability of natural systems to support and nurture life. To meet this
mandate, EPA's research program is providing data and technical support for solving
environmental problems today and building a science knowledge base necessary to manage our
ecological resources wisely, understand how pollutants affect our health, and prevent or
reduce environmental risks in the future.
The Center for Environmental Solutions and Emergency Response (CESER) within the Office of
Research and Development (ORD) conducts applied, stakeholder-driven research and provides
responsive technical support to help solve the Nation's environmental challenges. The Center's
research focuses on innovative approaches to address environmental challenges associated
with the built environment. We develop technologies and decision-support tools to help
safeguard public water systems and groundwater, guide sustainable materials management,
remediate sites from traditional contamination sources and emerging environmental stressors,
and address potential threats from terrorism and natural disasters. CESER collaborates with
both public and private sector partners to foster technologies that improve the effectiveness
and reduce the cost of compliance, while anticipating emerging problems. We provide technical
support to EPA regions and programs, states, tribal nations, and federal partners, and serve as
the interagency liaison for EPA in homeland security research and technology. The Center is a
leader in providing scientific solutions to protect human health and the environment.
This report provides an overview of EPA's Remediation Data Repository (RADAR) application
that provides a searchable database for accessing multi-hazard research and operational data
conducted by the U.S. EPA and other federal and international partners. Instructions for using
RADAR and associated technical documentation describing the technology architecture and
security controls are also included.

EXECUTIVE SUMMARY
This project supports United States Environmental Protection Agency's (EPA) Homeland
Security Research Program (HSRP) and the Center for Environmental Solutions and Emergency
Response, Homeland and Materials Management Division's strategic goals as described in
detail in the Homeland Security Strategic Research Action Plan (U.S. EPA, 2020). This work is
pertinent to Long-Term Goal 2, which states, "The [EPA] Office of Land and Emergency
Management (OLEM) and other clients use HSRP products and expertise to improve the
capability to respond to terrorist attacks affecting buildings and the outdoor environments."
Numerous decision support tools and technical/operational data have been developed under
EPA's HSRP. Collectively, the research data and tools support decision makers in a wide range of
emergency response and recovery activities. In many cases, tools developed under HSRP (and
elsewhere within the federal government) tend to rely on static data that are individually
distributed with each tool and are therefore susceptible to becoming out of sync with source
data updates; therefore, tools can be costly to maintain and keep up-to-date. Additionally,
technical/operational data generated through various research initiatives are often made
available through static reports that require an arduous amount of time to review or reference,
and the associated data are not easily accessed in a format that readily supports subsequent
research and modeling efforts.
To confront this issue, HSRP developed the Remediation Data Repository (RADAR), a searchable
database for accessing peer-reviewed multi-hazard research and operational data conducted
by EPA and other federal and international partners. The tool provides a central repository (i.e.,
database) that stores up-to-date data derived from HSRP literature reviews, studies, and tools,
and provides a user interface to increase the discoverability and applied use of research data.
RADAR is intended for use by a wide audience that includes scientists, engineers, and
operational experts. Delivering on-demand data to the right people at the right time enhances
the utility of the important research outputs that are generated.
RADAR allows EPA's homeland security specific research or operational guidance to be shared
among partners and a broad array of users by way of an online platform - an offering that
currently does not exist. RADAR provides users access to data both through a user-friendly
searchable interface and via an application programming interface (API) to facilitate
consumption of data by other HSRP tools through web services. This capability greatly reduces
the cost of updating models and tools and ensures end-users are referencing the most up-to-
date information, all the while significantly reducing development and maintenance costs. This
report provides an overview of RADAR, instructions for using RADAR, and associated technical
documentation describing the technology architecture and security controls.

1 INTRODUCTION
Numerous decision support tools and technical/operational data have been developed under
EPA's HSRP. Collectively, the research data and tools support decision makers in a wide range of
emergency response and recovery activities. In many cases, tools developed under HSRP (and
elsewhere within the federal government) tend to rely on static data that are individually
distributed with each tool and are therefore susceptible to becoming out of sync with source
data updates; therefore, the tools can be costly to maintain and keep up-to-date. Additionally,
technical/operational data generated through various research initiatives are often made
available through static reports that require an arduous amount of time to review or reference,
and the associated data are not harmonized using consistent taxonomy, units, and formatting,
nor are data easily accessed in a format that readily supports subsequent research and
modeling efforts.
To confront this issue, HSRP developed the Remediation Data Repository (RADAR), a searchable
database for accessing multi-hazard research and operational data conducted by EPA and other
federal and international partners. The tool provides a central repository (i.e., database) that
stores up-to-date data derived from HSRP literature reviews, studies, and tools, and provides a
user interface to increase the discoverability and applied use of research data. RADAR is
intended for use by a wide audience that includes scientists, engineers, and operational
experts. Delivering on-demand data to the right people at the right time enhances the utility of
the important research outputs that are generated. Figure 1 presents a high-level, conceptual
illustration of RADAR.

RADAR allows EPA's homeland security specific research or operational guidance to be shared
among partners and a broad array of users by way of an online platform - an offering that
currently does not exist. RADAR provides users access to data both through a user-friendly
searchable interface and via an application programming interface (API) to facilitate
consumption of data by other HSRP tools through web services. This capability greatly reduces
the cost of updating models and tools and ensures end-users are referencing the most up-to-
date information, all the while significantly reducing development and maintenance costs.
This report provides an overview of RADAR, instructions for using RADAR, and associated
technical documentation describing the technology architecture and security controls. This
report is structured in the following manner:
•	Chapter 2 discusses quality assurance/quality control activities;
•	Chapter 3 summarizes RADAR's technology architecture;
•	Chapter 4 provides instructions for using RADAR;
•	Chapter 5 describes how EPA users can submit data to include in RADAR;
•	Chapter 6 describes instructions for RADAR Administrators to approve and manage
registered users; and
•	Chapter 7 presents next steps and recommendations.
2	QUALITY ASSURANCE/QUALITY CONTROL
The purpose of this project was to develop a web-based application to provide EPA's HSRP the
capability to store, search, and discover research data. Software development activities
conducted during this project adhere to industry best practices and follow an EPA project-
approved quality assurance project plan (QAPP) that addresses requirements for software and
application development. The application was approved and cleared by ORD's Office of Science
Information Management (OSIM) and EPA's Office of Mission Support (OMS). No scientific
experiments were performed. Technical area leads evaluated the quality of the application
code and related technical documentation and security controls that were developed during
this effort.
Separately, the RADAR project is governed by a Configuration Management Plan and undergoes
monthly auditing.
3	RADAR INFORMATION ARCHITECTURE
RADAR's information architecture solution is built upon a cloud-based, open-source technology
stack to leverage a modern framework that enables rapid development and deployment and
optimal performance. The application-level architecture and user authentication components
of RADAR are described in the sections that follow.
10

-------
3.1 Application-Level Architecture
RADAR consists of the following system components:
•	Front-End - The front-end component powers the user experience. It provides the
interface to the user to allow interaction with all the pages, data, and document access.
The front-end also utilizes a subset of the data that drive the application and support
several operational and navigational features. The front-end presentation component
generally consists of HTML 5, CSS/Sass, JavaScript, and API web services consumption.
RADAR uses Vue.js1 as its user interface framework. The application utilizes the OneEPA
template and integrates user interface components from the U.S. Web Design System2.
•	Back-End and Server-Side Programming - The back-end powers the website and
consists of web servers, databases, and the server-side programming components and
business logic. The back-end component provides web services to supply data to the
front-end, as needed, based on user actions. Back-end data are stored in a PostgreSQL
database, and server-side programming prepares blocks of data by way of web services.
Server-side programming in the middle-tier is implemented using PHP (Laravel3
framework). Data are delivered using a representational state transfer (or RESTful) API
in JavaScript Object Notation (JSON) format for consumption by the front-end for
display to the user.
The database schema is maintained in version control using Laravel migrations, enabling
consistency across environments and a recorded history of schema updates.
•	Hosting Environment - RADAR is currently deployed in the General Services
Administration (GSA) cloud.gov environment. RADAR resides within an EPA/ORD
cloud.gov organization space and uses the standard cloud.gov provided PHP build pack
to support deployments. The cloud.gov environment offers a few noteworthy features
to improve the deployment process and increase website stability, including:
o Dynamic Scalability - If the application receives a large uptick in users or data
processing, the hosting platform can instantly scale to handle increased load,
o Automated Build Processes - Developers can create automated processes that
are triggered as code is updated. A set of steps (e.g., tests, code bundling, code
deployment) can be automatically run.
o Self-service Provisioning and Deployment - Developers can directly provision
services (e.g., increasing resources) and deploy applications.

3.2 Cloud-Level Architecture and User Authentication
Data and information included in RADAR can be searched and retrieved by any public user as
shown in Figure 3 below. Several additional features are provided for registered users that
successfully authenticate (i.e., successfully login). The mechanisms that govern these
interactions are briefly described below.

-------
3.2.1	Non-EPA User Flow
Other emergency response and operational stakeholders (e.g., state, local, other federal
agencies) are considered "non-EPA" users. EPA has a standard procedure for granting non-EPA
users access to EPA applications that require a login. Described below are procedures used and
actions that are available for a non-EPA:
•	A user uses their web browser to navigate to the publicly accessible RADAR application.
•	The PHP-based cloud.gov server delivers the RADAR client application (HTML, CSS,
JavaScript, images.) to the user.
•	As the user interacts with the application:
o For non-authenticated users (i.e., not logged in), the client application invokes
application-level web services on the cloud.gov server which retrieves read-only data
from the PostgreSQL based database.
o For authenticated users (i.e., logged in), the application provides additional features
(see Chapter 4).
3.2.2	EPA User Flow
The user flow for EPA employees accessing the application is generally same as for non-EPA
users with one notable difference. If an EPA user is connected to the EPA network, the web
browser to application server communication traverses a Trusted Internet Connection (TIC)
route that EPA has established as opposed to going through normal public internet routes. This
communication channel does not change how the application behaves.
3.2.3	RADAR User Roles
RADAR institutes several role-based features that are accessible based on roles that are linked
to registered users. RADAR user roles are managed via EPA's Web Access Management (WAM)
system. Registered users are those users who have requested access to RADAR via the EPA
WAM portal and are able to login to RADAR. The following roles and corresponding capabilities
exist within RADAR:

Metadata requirements must be fulfilled when adding data to RADAR. RADAR metadata
requirements comply with the Project Open Data Metadata Schema that is used by the
Environmental Data Gateway (EDG) (See: Metadata Technical Specification for non-geospatial
data) and also include additional metadata fields that are unique to RADAR to support
application search functionality. For instances where datasets might already be published with
an activated Digital Object Identifier (DOI), RADAR provides users with the option to retrieve
existing metadata; otherwise, data entry prompts for required fields are presented for
completion.
5.2.1 Find / Enter Metadata
RADAR will pre-populate metadata from EDG if the dataset has already been published with an
activated DOI. Different data entry options are presented based on the following scenarios;
•	Whether a dataset has a DOI,
•	Whether a dataset is derived from a published EPA Report, or
•	Whether a dataset only has an approved QAPP.
26

-------
5.2.1.1 Dataset with a Digital Object Identifier (DOI)

5.2.4 Dataset Review Process
After a dataset is uploaded, RADAR requires that the dataset be reviewed and approved prior
to the dataset becoming discoverable in RADAR. Figure 30 illustrates the overall workflow of
the dataset review process. The sequence of reviews depends on whether the dataset has a
DOI, EPA Report Number, or QA Activity Number as specified when uploading the dataset.
RADAR notifies reviewers and administrators accordingly as datasets are queued for review and
approval.

Figure 30. Dataset review process workflow.
Reviewers can add comments next to any metadata field or dataset field, They can also add an
overall comment for anything that is not specific to a field for the user who contributed the
data to resolve. If comments are added and changes are required, the RADAR reviewer or
administrator can send comments back to the user for resolution. The dataset will remain
pending until RADAR review or administrator comments are satisfied. Should a user choose not
to address comments, users can rescind the dataset submission and delete the dataset from
RADAR.
41

-------
RADAR provides a notification alert to any pending actions that require a user's attention.
When a RADAR user navigates to Upload Data area, a table is displayed that presents their
datasets along with statuses and actions as shown in Figure 31. Datasets can have the following
statuses:
•	Incomplete
•	Pending QA Review
•	Pending Technical Review
•	Pending Admin Review
•	Denied
•	Approved
Datasets marked as incomplete will include an action to continue the dataset submittal process,
which will link to the Data Upload form where fields already entered are pre-filled. As shown in
Figure 31 below, an outstanding action to Address Comments on a pending dataset is displayed.
Users should click Address Comments to view and resolve reviewer comments. Selecting the
Address Comments button opens the submittal form displaying comments that must be
addressed prior to advancing through the review sequence.

Figure 32. Example reviewer metadata comments.
Users can update any field that requires attention and then resubmit. Resubmitting will alert
the reviewer of a pending dataset, where the reviewer can verify whether comments were
satisfactorily addressed. Reviewers will then either approve the dataset or add additional
comments for resolution. This review cycle will incrementally continue until all comments are
addressed from all reviewers.
Once no comments remain or if the initial dataset entry does not require revisions, the RADAR
Admin will approve the dataset for inclusion in RADAR. After approval, the dataset will be
visible to all RADAR users.
Note: Should a dataset be denied (i.e., returned to the user for further review) or if a user
would find it easier to start over, users can delete any dataset with a status of Denied or
Incomplete. If datasets are pending reviews, no additional action can be taken by the user who
contributed the data until a reviewer returns the dataset. If a dataset is approved, only a
RADAR Admin can disable a dataset from view with RADAR.

As discussed in Section 5.2.4 and illustrated in Figure 30, the overall workflow of the dataset
review process depends on whether the dataset has a DOI, EPA Report Number, or QA Activity
Number as specified when uploading the dataset. The sections that follow describe
components of the workflow that correlate with different dataset review status categories.
6.1 Pending QA and/or Technical Review
Datasets that require a QA Manager to first approve the dataset (based on the existence of an
associated EPA Report Number and/or QAPP) will appear as a pending action for users with a
QA Reviewer role. As shown in Figure 33, RADAR will alert users who have pending actions with
a notification that will appear at the top of the page. Users can click the Pending Actions button
to go directly to the Upload Data page. Any datasets that require a user's attention will be
separately displayed in a table noting the same. Depending on the status, the value in the
status column will show: Pending QA Review, Pending Technical Review, or Pending Admin
Review.
Reviewers can click the Review button to begin reviewing both the metadata and data that
were submitted.

Figure 36, Enter review comments and return to user who contributed data.
Otherwise, following verification that an approved QAPP exists, and that the review did not
identify any issue to resolve, the OA Reviewer will queue the dataset to a Technical Reviewer
for review. A Technical Reviewer will follow the same steps as the QA Reviewer. Following
approval by a Technical Reviewer, the RADAR Admins will be notified to complete a final
review. Figure 37 illustrates the buttons for the Technical Reviewer view.

7 NEXT STEPS AND RECOMMENDATIONS
EPA's HSRP continuously strives to find innovative ways to support its scientists and
stakeholders. Data are an integral component to all research and how researchers access and
use data is changing, and forward-thinking solutions to facilitate these changes are needed. The
RADAR project supports EPA's larger goal to collectively work from standardized data elements
to improve relatability among similar research datasets and standardize communication of
49

-------
research. Data element harmonization can be facilitated using standardized data capture forms
and can be enforced through validation procedures established for data upload features used in
RADAR. At present, RADAR provides the initial framework to establish a more robust process
for exposing HSRP research data. Incremental advances are in place to support achieving this
larger goal.
RADAR facilitates structuring data to separate and explicitly format data by type (i.e., text,
integer, numeric). This project has moved efforts forward by providing a platform to centrally
store homeland security research data and intentionally organize data in a structured manner.
Separating numeric values from units is one simple example. By providing a template to
organize data in a structured format, capture key metadata to aid data discovery and reuse,
and enforce basic validation principles, RADAR is facilitating better connections to research
data by other researchers and other tools and models.
Additionally, as the compilation of datasets included in RADAR expands, the tool will provide
emergency response personnel and decision makers the prompt and concise information that is
required to effectively perform their tasked objectives. RADAR will also facilitate the other
decision support tools and models in sourcing the most current research from a central data
repository through modern communication mechanisms (i.e., shared services).
While the technological solution to support EPA in achieving its goal is in place, the ultimate
success is rooted in adoption by researchers to support building out the repository. Work is
underway to identify additional opportunities to further advance harmonization efforts to
standardize terminology, preferred units, and related metadata. This will improve the ability to
merge and compare multiple datasets within RADAR. It could also allow for development of
more robust data validation (e.g., detecting and flagging outlier values) in the future. Upon
building consensus within the HSRP researchers, additional data validation mechanisms can be
built into RADAR to enforce data integrity standards that are prioritized and adopted by the
program.
In addition, demonstrating the value and utility of RADAR by way of real-world examples is
crucial to generate support and buy-in from stakeholders. Illustrating the benefits and directly
addressing the "why should I do this" to build consensus among HSRP researchers will ensure
EPA can achieve its vision and that those who stand to benefit most are part of refining the
solution.
