Governance Alliance Partnerhip
Delivering Clinically Sound Environmental Assessment,
Biotoxin Decontamination, and Remediation.
The Purified Environments Provider Network (PEPN™) PEPN is a national governance alliance advancing clinically aligned environmental purification.
Participation is offered through partnership to independent organizations capable of implementing the PEPN-HEART™ protocol under oversight, verification, and evidence contribution,
when human health is a material concern.
Why PEPN Was Created
For decades:
- Clinical medicine evaluated patients and symptoms
- Environmental remediation addressed buildings structurally
These two domains evolved independently, with no governing body responsible for aligning environmental work to clinically relevant outcomes.
As scientific understanding of environmental biotoxins expanded, it became clear that:
- Traditional remediation standards were designed for structural conditions, not health tolerance
- Visual or procedural completion did not reliably equate to reduced exposure
- There was no national framework to ensure environmental work could be validated, repeated, or reviewed through a health-aligned lens
PEPN was created to close that gap.
Health-Relevant Alignment
PEPN governance requires environmental assessment, biotoxin characterization, and remediation practices to be designed around health relevance and tolerance, not solely structural correction or visual completion.
Partner Governance
PEPN is not an open directory. Participation is limited to qualified professionals who meet defined education, credentialing, training, and performance requirements and who agree to operate under PEPN governance.
Verification & Accountability
Environmental work under PEPN governance is documented, measurable, and verifiable. Outcomes are evaluated using objective environmental data and post-work confirmation, with accountability mechanisms for non-compliance.
The Center for Indoor Air Quality and Human Health
The Purified Environments Provider Network™ (PEPN™) operates as an independent governance alliance aligned with the work of the Center for Indoor Air Quality and Human Health, a nonprofit organization dedicated to advancing research, education, and health-focused guidance related to indoor environmental exposure.
The Center is led by Dr. Andrew Heyman, MD, MHSA, and brings together medical experts, research scientists, and policy professionals to advance education, data collection, and research publication related to indoor environmental health.
PEPN™ standards and governance frameworks are informed by emerging science and clinical insight translated by the Center, while remaining fully operationally and organizationally independent. This alignment supports PEPN™’s mission to elevate environmental practice through clinically relevant, defensible, and scalable governance—without creating endorsement, control, or dependency between the organizations.
Independent by Principle
PEPN’s independence is not incidental — it is foundational. Free from certification trade influence and financial conflicts of interest, the network operates with impartial governance and a commitment to anonymized environmental data collection in support of future peer-reviewed scientific research.
PEPN was intentionally structured to maintain independence, impartiality, and public trust. To that end:
- PEPN does not perform remediation, decontamination, cleaning, or construction work. The network governs standards, oversight, and verification — it does not act as a service provider.
- PEPN does not interfere with alliance partners’ businesses or pricing. Partners retain full control over their business models, fees, and client relationships.
- PEPN does not write contracts, sell projects, or transact work. All scopes of work and commercial agreements remain strictly between partners and their clients.
- PEPN does not sell, broker, or monetize inquiries or referrals. The network is not a marketplace, referral engine, or consumer lead platform.
- PEPN may receive inquiries and facilitate connection to qualified alliance partners. This facilitation is non-commercial and exists solely to ensure inquiries are directed to providers operating under PEPN governance standards.
- PEPN does not operate as an open directory or advertising platform. Alliance partnership is governed, selective, and subject to ongoing oversight.
- PEPN does not certify professionals or sell credentials. PEPN holds no ownership or financial interest in any certification or credentialing body and serves all credentialing organizations impartially.
- PEPN does not diagnose, treat, or manage medical conditions. All work governed by PEPN remains environmental and non-clinical in nature.
- PEPN does not guarantee health outcomes. The network governs assessment standards, environmental testing, work processes, quality assurance oversight, and post-intervention verification — not individual medical results.
Behind every environmental problem is a human story.
PEPN and its Governance Alliance are advancing a new standard — moving an industry beyond structural repair toward health-aligned environmental accountability.
