Birchtech’s division, WE2C Environmental, is dedicated to creating cost-effective solutions for removing "forever chemicals" (PFAS) that help utilities manage compliance costs without burdening consumers. Our mission is clear: to bring the same advancements to water that we’ve already achieved in air. We believe that water free from harmful chemicals should be accessible and affordable—an essential right, not a privilege.
The Challenges Water Utilities Face
Water utilities across the U.S. are under increasing pressure to comply with new regulations around “forever chemicals” (PFAS), and the cost for EPA’s PFAS reduction is expected to cost utilities more than $47 billion in the coming years. However, the cost of compliance is only part of the problem. Utilities face additional concerns in two main areas:
1) Supply Shortages and Rising Costs of Virgin Activated Carbon: Granular activated carbon (GAC), recognized as the “Best Available Technology” (BAT) for contaminant removal, has seen price increases of over 50% in the past 12-18 months due to rising raw material costs and industry demand. These spikes could eventually impact consumers as utilities manage increased costs to maintain compliance.
2) Disposal Challenges: After GAC is used to remove contaminants, the spent carbon is often discarded, creating additional costs and environmental concerns. The USGS (United States Geological Survey) has recently reported growing concerns of PFAS in groundwater. With rising costs associated with disposal and the growing challenge of safely managing PFAS-laden waste, utilities are looking for more efficient and cost-effective ways to handle disposal.
The Impact on Consumers
As utilities face higher compliance and disposal costs, there’s a potential for these increases to impact consumers over time. We’re dedicated to providing innovative solutions that help utilities manage these costs efficiently, aiming to keep clean drinking water as accessible as possible.

Thermal reactivation of spent granular activated carbon (GAC) is a sustainable and cost-effective method for removing per- and polyfluoroalkyl substances (PFAS) from potable water. However, understanding the impact of pore size distribution on adsorption is crucial for water utilities aiming to optimize PFAS removal. GAC consists of millions of pores classified as micropores, mesopores, and macropores, with micro- and mesopores being the most effective for PFAS adsorption. Thermal reactivation can alter pore size distribution by widening micropores, which may enhance the adsorption of natural organic matter (NOM) but could also negatively affect PFAS removal efficiency. Additionally, repeated reactivation cycles may further change pore structure, making lab- and pilot-scale testing essential.
Another key consideration is calcium catalysis, an often-overlooked factor in thermal reactivation. Calcium, which naturally accumulates in GAC during water treatment, can accelerate the transfer of oxygen during reactivation, leading to an unwanted "drilling effect" that widens pores. While this is less of a concern for short service durations, prolonged use and multiple reactivations can lead to significant pore alterations, potentially reducing PFAS adsorption capacity.
To maximize efficiency, water utilities should evaluate calcium levels in raw water and assess GAC performance through rapid small-scale column testing (RSSCTs). Consulting experts in thermal reactivation and water quality can help utilities optimize GAC reuse, ensuring cost savings and regulatory compliance while minimizing environmental impact.
Granular activated carbon (GAC) has long been a cornerstone of municipal water treatment, particularly in removing harmful PFAS contaminants. However, with new EPA regulations setting PFAS limits in the low parts per trillion (ppt), GAC usage is surging, leading to increased operational costs and supply chain strain. A promising solution to these challenges is thermal reactivation of "spent" GAC, which can significantly cut costs, alleviate supply issues, and reduce environmental impact by minimizing landfill waste and lowering the demand for virgin GAC production.
Reactivated GAC offers utilities potential cost savings of up to 50% compared to new GAC, which now approaches $2.00 per pound. Despite these benefits, ensuring the reactivated product performs as effectively as virgin GAC is crucial. This is where Rapid Small-Scale Column Testing (RSSCT) plays a vital role. RSSCT provides quick and reliable data on the performance of reactivated GAC, allowing utilities to determine the optimal blend of reactivated and virgin GAC for maximum efficiency at minimal cost. Unlike full-scale testing, which can take months, RSSCT delivers results within days, making it a practical tool for optimizing water treatment systems.
By leveraging RSSCT, utilities can fine-tune their GAC strategies, maintain consistent contaminant removal, and achieve significant cost reductions. This approach ensures sustainable water treatment while addressing the increasing demand for PFAS removal in a rapidly evolving regulatory landscape.

Revolutionizing the Removal of Forever Chemicals in Water: Addressing a $47 Billion Challenge
Water utilities across the U.S. are grappling with increasing complexities in delivering clean, safe drinking water, driven by rising costs and supply chain challenges. A major contributor to this crisis is the presence of PFAS, harmful chemicals linked to cancer, heart disease, and other serious health issues. ME2C Environmental is stepping up to meet this urgent need with the launch of WE2C Environmental and two cutting-edge laboratories, the Carbon Development & Emerging Contaminant Analysis labs, dedicated to water purification.
Tackling the Forever Chemical Crisis
The Environmental Protection Agency (EPA) has stressed the critical need for effective PFAS removal. In April 2024, new monitoring data underscored the vast scale and costs involved in addressing this issue. According to updated analyses, reducing PFAS exposure for 35 million Americans could cost $37.1 to $48.3 billion over five years, with annual maintenance expenses reaching up to $3.5 billion. This creates a pressing demand for innovative, cost-efficient solutions.
