Setting the Standard for Health-Aligned Environmental Practice.

The Purified Environments Provider Network (PEPN™) is a national professional network advancing higher standards in environmental assessment, biotoxin decontamination, remediation, and verification when human health is a material concern.

Through the PEPN-HEART™ framework, qualified independent professionals operate within a unified system of training, technical standards, oversight, verification, and evidence-informed practice—creating greater consistency, accountability, and collaboration across the environmental industry.

PURIFIED ENVIRONMENTS PROVIDER NETWORK™

The Future of Environmental Health

Advancing environmental health through governance, science, accountability, and measurable outcomes.

A DEFINING SHIFT

Redefining the Relationship Between the Built Environment and Human Health

The Purified Environments Provider Network™ represents a defining shift in how the environmental services industry relates to human health. By establishing a national governance alliance built on clinical alignment, independent oversight, and evidence-based verification, PEPN is setting a new standard — one where environmental work is not complete until it is measurable, defensible, and health-relevant.

CLINICAL ALIGNMENT

Creating a common language between environmental professionals and healthcare providers while maintaining clear professional boundaries.

INDEPENDENT OVERSIGHT

Establishing governance, accountability, documentation, and professional expectations across participating organizations.

EVIDENCE-BASED VERIFICATION

Moving beyond completion of work toward objective measurement of environmental conditions and intervention outcomes.

A NEW PROFESSIONAL STANDARD

Environmental work is not complete until it is measurable, defensible, and health-relevant.

THE PEPN™ GOVERNANCE ALLIANCE

Professional Independence. Shared Accountability.

For independent organizations capable of implementing the PEPN-HEART™ Protocol under oversight, verification, and evidence contribution, partnership in the PEPN alliance represents an opportunity to operate at the highest level of professional accountability in the field.

THE GOVERNANCE MODEL
EDUCATION → PROTOCOL → OVERSIGHT → VERIFICATION → EVIDENCE → IMPROVEMENT
BUILDING THE EVIDENCE

Every Project Can Contribute to Something Larger.

PEPN's governance framework ensures that every partner contributes to a growing body of anonymized environmental data intended to support future scientific analysis and peer-reviewed research.

CLOSING THE GAP

Connecting Environmental Science With Human Health

The gap between clinical medicine and environmental remediation has existed for decades. PEPN exists to close it — permanently, systematically, and with the rigor that human health demands.

THE FUTURE OF ENVIRONMENTAL HEALTH

A Higher Standard of Environmental Accountability.

Science-driven. Independently governed. Measurably verified. Focused on exposure.

THE REASON BEHIND THE NETWORK

Why PEPN Was Created

For decades, clinical medicine evaluated patients and symptoms while environmental remediation addressed buildings structurally. These two domains evolved independently, with no governing body responsible for aligning environmental work to clinically relevant outcomes.

PEPN was created to close that gap.

By uniting clinical understanding with environmental practice under a single governance framework, PEPN ensures that remediation outcomes are measured not just by structural correction — but by their relevance to human health and occupant safety.

This represents a fundamental shift in how the industry defines success.

The PEPN-HEART™ Protocol

A specialized scientific framework for environmental health intervention.

The PEPN-HEART™ Protocol is a specialized scientific framework established to define environmental health intervention as an independent professional discipline.

A DIFFERENT APPROACH

Unlike traditional remediation that focuses primarily on structural repairs, this system prioritizes the evaluation and reduction of inhalation-based biological hazards within occupied buildings.

THE SCIENTIFIC FOUNDATION

Built Upon Interdisciplinary Science

Its foundation is built upon decades of interdisciplinary global research, integrating environmental science, building science, exposure science, medicine, and public health.

DATA-DRIVEN ENVIRONMENTAL HEALTH

Measure the Exposure.
Measure the Intervention.

The PEPN-HEART™ framework utilizes objective environmental data to characterize biologically active exposure burdens and evaluate whether intervention efforts have meaningfully reduced exposure pathways within the built environment.

THE PEPN-HEART™ QUESTION
Did the intervention measurably reduce the biological exposure burden?
THE PEPN-HEART™ FRAMEWORK
CHARACTERIZE → IDENTIFY → INTERVENE → REDUCE → VERIFY → STABILIZE

From Damage-Focused Remediation to Exposure-Focused Environmental Health

PEPN-HEART™ evaluates the indoor environment through the lens of human exposure—using environmental science, objective measurement, and verification to determine whether meaningful reductions in biological exposure pathways have been achieved.
