On September 2, 2021, the EPA’s Office of Water, in partnership with the DoD’s Strategic Environmental Research and Development Program, published draft Method 1633.

In the environmental industry, many of us are familiar with Volatile Organic Compounds (VOCs) but some may not know that a subset exists known as Highly Reactive VOCs (HRVOCs).

In this blog, we’re taking that field experience and sharing our best tips to ensure you are met with success when submitting air samples to the lab.

For the first time ever, the EPA will be adding a compound to the Hazardous Air Pollution (HAP) list.

Welcome to our Green Building June Takeover blog series. This week, we will explore the chemistry of the air and trends that we have observed when the volatile organic compound (VOC) air quality parameters do not meet the requirements.

When thinking about Green Building certification, it’s important to factor in the indoor environment and air quality. Indoor Environmental Quality (IEQ)/Indoor Air Quality (IAQ) are the conditions inside a building—air quality, lighting, thermal conditions, ergonomics—and their effects on occupants.

Understanding what “Green Buildings” are and identifying the organizations that offer certification is just the start to a green building journey.

Despite the disruptions caused by the pandemic, the Green Building and Products industry has not shown any signs of decline.

An Environmental Site Assessment (ESA) evaluates property conditions concerning contamination and environmentally hazardous materials.

Many people often overlook the obvious when attempting to locate Volatile Organic Compounds (VOCs) in their homes. They may expect finding VOC and mold sources to be a daunting task, but this is not the case.

In July, new updates were adopted to highlight better land disposal practices in the area covered by the San Francisco Regional Water Board. Order R2-2020-0023 (June 2020) – General Waste Discharge Requirements (WDR) amendment applies to all active Region 2 landfills and sets new criteria for disposal of soils, and requires each landfill to submit an updated Waste Acceptance Plan

The potential aggregate effect to aquatic lifeforms from all pollutants confined within a facility’s wastewater is tested by means of Whole Effluent Toxicity; it is part of the implementation of the Clean Water Act to monitor the discharge for toxic contaminants.

If you manage hazardous waste in California, you may have heard the terms “TTLC, STLC, and TCLP”, but what do these mean and when do you need to use them?

40 CFR Part 64 Subpart FFFF establishes National Emission Standards for Hazardous Air Pollutants (NESHAP) for Miscellaneous Organic Chemical Manufacturing (MON). This subpart establishes requirements to demonstrate initial and continuous compliance with the emission limits, operating limits, and work practice standards.

Per- and polyfluoroalkyl substances (PFAS) are considered emerging contaminants by the Environmental Protection Agency (EPA) and are of great public health and environmental concern.

Dredge work that potentially impacts federally regulated waters requires a permit from the Army Corps of Engineers. The New England District of the Corps (CENAE) is responsible for permitting work conducted in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont.

A winter chill has floated into Research Triangle, NC and will likely transitioned to a cold shiver as we move through the winter months. Meanwhile, our stack-tester friends are still going strong out in the field knocking out one test after another.

On December 1, 2020, the State Water Resources Control (State Board) approved the California Statewide Toxicity Provisions.

WFH – work from home, WFA – work from anywhere, remote office, mobile work, remote job, future of work, flexible workplace, telework, teleworking….and the list goes on. Whatever you or your company call this new reality, it seems as though “workplaces” will be changed indefinitely.

After many years of drafts, comments, discussion, debate, consideration, and negotiation, the California Statewide Toxicity Provisions are expected to be considered for approval by the State Water Resources Control (State Board) in December 1, 2020.

Whole Effluent Toxicity (WET) testing is a critical component of monitoring the health of aquatic ecosystems and it is included in many National Pollutant Discharge Elimination System (NPDES) permits. If your NPDES permit includes WET testing, it is important to understand why it exists and how to best implement it in order to save time, money, and other resources.

As we move towards reopening from this pandemic, Legionella testing has been ramping up to ensure the safety of our front-line defenders battling COVID-19, educators, and future generations from the stagnant water left within buildings during the shelter-in-place.

Welcome to the Enthalpy Analytical blog!! We’re excited about this launch and look forward to sharing our journey each step of the way as we blaze new trails and explore new ideas in environmental laboratory testing services.
