WHY PFAS ARE A GROWING CONCERN

Per- and polyfluoroalkyl substances (PFAS), commonly called “forever chemicals,” have emerged as a leading environmental concern due to their persistence in water, soil, and air—and their potential to impact human and ecological health. As testing requirements and discharge limits continue to tighten, organizations are encouraged to take a proactive approach to PFAS compliance and remediation.

PFAS are resistant to natural degradation and are increasingly found in industrial discharges, municipal waste streams, drinking water, and groundwater. Regulators are responding with strict standards—driving the need for accurate data, site-specific risk assessments, and targeted cleanup plans.

Persistent toxicity in wastewater effluents can place your operations at risk of exceeding Whole Effluent Toxicity (WET) limits in an NPDES permit—resulting in potential penalties, project delays, or reputational damage. At EnviroScience, we help facilities across a wide range of industries identify, resolve, and prevent effluent toxicity issues through expert Toxicity Identification Evaluations (TIEs) and Toxicity Reduction Evaluations (TREs).

What Is a TIE/TRE Evaluation?

A Toxicity Identification Evaluation (TIE) is a structured, EPA-approved methodology used to determine the specific toxicants responsible for observed toxicity in effluents. Once the suspected source of toxicity is known, a Toxicity Reduction Evaluation (TRE) implements corrective actions to mitigate or eliminate these toxicants—ensuring regulatory compliance and long-term environmental sustainability.

Why Whole Effluent Toxicity Compliance Matters

WET testing is a key requirement under the Clean Water Act and NPDES permitting. Regulatory agencies may mandate a TIE/TRE investigation to restore compliance when toxicity is detected in effluent discharges. Without timely resolution, your organization may face:

• Expensive enforcement actions
• Delays in permit renewals
• Project shutdowns or discharge limitations
• Negative community or public perception

EnviroScience’s Proven TIE/TRE Process

With over 35 years of regulatory and laboratory experience, EnviroScience provides a full-service, stepwise TIE/TRE approach designed to address compliance targets and reduce operational disruptions efficiently.

Our process includes:

✅ Adherence to EPA toxicity testing protocols
✅ Establishing baseline toxicity through in-house WET testing
✅ Site-specific evaluations of plant operations, chemical usage, and treatment processes
✅ Data-driven recommendations to eliminate toxicity at the source
✅ Ongoing technical support throughout regulatory interactions

Customized Toxicity Solutions for Your Industry

Our TIE/TRE services are tailored to the needs of:

• Municipal wastewater treatment plants
• Industrial and manufacturing facilities
• Chemical processors
• Power generation stations
• Mining and extraction operations

No matter your industry, we help you meet your discharge permit requirements and minimize the risk of costly fines or shutdowns.

Case Study: How We Helped a Client Avoid Six-Figure Penalties

One industrial facility faced recurring toxicity exceedances that jeopardized its permit renewal. Within 90 days of initiating a TIE/TRE with EnviroScience, we identified the key contributors to effluent toxicity and recommended targeted process adjustments.

The result: complete elimination of exceedances and regulatory approval—without costly plant upgrades.

FAQs: TIE/TRE and Whole Effluent Toxicity Testing

Q: What is the difference between a TIE and a TRE?
A: TIE identifies the suspected toxicants responsible for noncompliance. A TRE follows up by applying and evaluating corrective actions to reduce or eliminate that toxicity.

Q: Why would my facility need a TIE or TRE?
A: If your discharge fails a WET test or shows persistent toxicity in bioassay results, regulators may require a TIE/TRE to investigate and correct the issue.

Q: How long does the TIE/TRE process take?
A: The timeline varies, but most initial TIE evaluations and recommendations are completed within a few weeks. Ongoing support is provided as necessary during the implementation of the TRE corrective action.

Q: What regulations require TIE/TRE testing?
A: EPA and state agencies require TIE/TRE under the Clean Water Act when WET testing indicates recurring or unexplained toxicity in effluent discharges.

As regulatory changes continue to unfold in 2025, another high-impact proposal is poised to reshape how environmental reviews are conducted nationwide: a move to significantly scale back habitat protections under the Endangered Species Act (ESA). At EnviroScience, we stay ahead of such developments so our clients—especially those managing federally funded infrastructure and development projects—can make informed, confident decisions.

In this article, we break down the proposed rule, examine its implications, and share how our team will continue to support endangered species compliance no matter how the regulatory environment evolves.

What’s Changing Under the Endangered Species Act?

On April 16, 2025, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service proposed a rule to rescind the regulatory definition of “harm” under the ESA. This would remove habitat modification from the scope of what constitutes prohibited “harm” to listed species—a major shift from longstanding policy. If finalized:

• Habitat destruction would no longer be considered harm, even if it affects species’ ability to breed, feed, or shelter
• Regulatory oversight for protecting critical habitat areas could be significantly weakened

Read about the proposed rule here:

https://www.federalregister.gov/documents/2025/04/17/2025-06746/rescinding-the-definition-of-harm-under-the-endangered-species-act

Implications for Environmental Review and Compliance

While this rule is still under review and open to public comment, it has major implications for:

• Endangered species permitting
• NEPA and ESA coordination
• Biological assessments and federal consultations

Although this proposal may appear to ease regulatory burdens for developers, it could increase legal risks, especially if litigation arises over how “harm” is interpreted in sensitive or contested habitats. Inconsistent application of these changes across agencies and courts may also complicate project planning and approvals.

How EnviroScience Ensures Endangered Species Compliance

EnviroScience remains committed to helping you navigate endangered species protections under any regulatory framework. Our expertise spans ecological science, environmental law, and interagency coordination.

Threatened & Endangered Species Surveys

We conduct comprehensive habitat assessments and field surveys to:

• Detect presence of listed species
• Evaluate potential project impacts
• Provide mitigation guidance that aligns with ESA, NEPA, and U.S. Army Corps of Engineers requirements

Even if habitat protections are scaled back under federal definitions, our clients benefit from documentation that supports:

• Legal defensibility
• Permit application success
• Stakeholder and community transparency

Environmental Compliance Services

From early-phase planning through post-construction monitoring, we help clients anticipate and meet environmental compliance needs—even as laws change.

Should I Adjust My Project Plans?

For now, the rule is only proposed—it is not yet law. We recommend that clients:

• Continue existing species survey protocols
• Maintain a precautionary approach where habitat conflicts may arise
• Consult early with environmental specialists (like us!) to understand risk exposure

A change in regulation doesn’t remove a project’s need for scientific accountability, public transparency, or due diligence—especially on federal, DOT, or grant-funded projects.

Stay Informed with Expert Environmental Consultants

EnviroScience will continue to track the ESA rule and interpret how it may affect permitting processes, fieldwork standards, and agency consultation. No matter the outcome, our clients can count on accurate guidance, streamlined project support, and environmental solutions backed by science.

Contact us today to discuss how this proposed rule may affect your project or to schedule a Preliminary Site Assessment.

What Is Ecological Uplift?

Ecological uplift refers to the measurable improvement of habitat quality, water quality, and overall ecosystem function following environmental restoration. At Veterans Legacy Woods, this principle guided every aspect of our stream and habitat restoration work—transforming a former golf course into a thriving natural system.

Stream Restoration in Ohio’s Veterans Legacy Woods

Located in Newbury Township, Geauga County, Veterans Legacy Woods is a public park owned and managed by the Geauga Park District. Once a golf course, the site has been reimagined as a dynamic ecosystem supporting aquatic and terrestrial wildlife.

EnviroScience worked closely with the Geauga Park District team, alongside RiverReach Construction and GPD Group, to implement a restoration plan designed to achieve long-term ecological uplift. Our team led the ecological design and construction of a coldwater stream, sourced from a natural spring, along with enhancements to the wetland and riparian areas.

Coldwater Stream Construction for Habitat and Water Quality

The project’s centerpiece is a 1,500-linear-foot coldwater stream built using natural channel design techniques. This spring-fed system was engineered to provide consistent base flow, cool temperatures, and habitat features that support sensitive aquatic species.

Key design elements include:

• Rocky substrates for macroinvertebrate colonization
• Leaf packs and woody debris to support food web development
• A shaded, meandering channel for temperature regulation and hydrologic stability

This headwater stream restoration represents a rare opportunity in Ohio to establish high-quality coldwater habitat with long-term ecological potential.

Enhancing Wetlands to Support Ecological Uplift

In addition to stream construction, two new wetlands were built to enhance site hydrology, promote nutrient uptake, and expand aquatic habitat. These wetlands contribute to overall ecological uplift by increasing biodiversity and improving water quality.

The design supports the growth and resilience of wetland vegetation while integrating with the site’s new hydrologic regime.

Riparian Reforestation for Habitat and Stream Health

To stabilize streambanks and restore native plant communities, EnviroScience’s vegetation services team reforested approximately 9.5 acres of riparian buffer. More than 2,400 native trees and shrubs were installed, selected based on soil and moisture conditions to ensure long-term survivability.

This reforestation effort:

• Enhances riparian habitat complexity
• Improves stream shading and temperature control
• Provides critical food and cover for birds, pollinators, and small mammals

Invasive Species Management to Protect Restoration Gains

Invasive plants, such as reed canary grass and purple loosestrife, were treated using invasive species management techniques, ensuring that native plants can establish successfully.

Our team’s long-term stewardship plan includes mechanical control, selective herbicide treatment, and ongoing monitoring to support the integrity of restored habitats.

A Showcase of Park Restoration and Public Benefit

Veterans Legacy Woods is more than a restoration site—it’s a vibrant, visitable natural area within the Geauga Park District. Public trails now weave through reforested slopes, emergent wetlands, and the newly built stream, offering a firsthand look at how ecological restoration enhances public lands.

This project exemplifies what is possible when park districts, restoration professionals, and ecologists collaborate to rewild formerly altered landscapes for long-term functionality and public benefit.

Frequently Asked Questions

What is ecological uplift in restoration projects?
Ecological uplift refers to the measurable improvements in ecosystem function, habitat quality, and biodiversity that result from intentional restoration activities. It’s a core goal of many stream, wetland, and habitat projects.

What makes a coldwater stream different from other streams?
Coldwater streams maintain lower temperatures year-round, typically due to spring-fed sources or shaded environments. They support specialized aquatic species, including sensitive macroinvertebrates and fish.

Why is stream restoration important in Ohio?
Many of Ohio’s headwater streams have been historically altered or degraded. Stream restoration improves water quality, stabilizes hydrology, promotes biodiversity, and facilitates the reconnection of ecosystems in a changing climate.

Can the public visit Veterans Legacy Woods?
Yes! Veterans Legacy Woods is open to the public and managed by the Geauga Park District. Visitors can enjoy trails, restored natural areas, and seasonal blooms throughout the park.
