Birchtech Appoints Charlie Cooper as Business Development Manager, Strengthening Its Commitment to Rural and Small Water Systems

Cooper Brings 21 Years of Water Treatment Experience, from Mine Water Discharge to Drinking Water, Including Five Years Overseeing the West Virginia Rural Water Association’s Emerging Contaminants Program

CORSICANA, Texas, Oct. 01, 2026 (GLOBE NEWSWIRE) -- Birchtech Corp. (NYSE American: BCHT) (TSX: BCHT) (“Birchtech” or the “Company”), a leader in specialty activated carbon technologies for sustainable air and water treatment, today announced the appointment of Charlie Cooper as Business Development Manager, effective October 1, 2026. In this role, Mr. Cooper will lead efforts to develop and expand Birchtech’s relationships with municipalities, public service districts, and utility operators, with a focus on rural and small water systems.

Mr. Cooper brings 21 years of hands-on water treatment experience, spanning industrial mine water discharge to municipal drinking water. Most recently, he spent five years with the West Virginia Rural Water Association (WVRWA), overseeing its Emerging Contaminants Program and helping systems across the state prepare for new testing, treatment, and regulatory demands. Before joining WVRWA, Mr. Cooper served as a Water Plant Operator for the City of Lewisburg, West Virginia, gaining frontline experience running a public drinking water system. Earlier in his career, Mr. Cooper led the Environmental Department at Alpha Natural Resources, then one of the nation’s largest coal producers, managing water treatment and compliance across 131 mining permits.

Mr. Cooper’s appointment reflects Birchtech’s strategic focus on expanding its water treatment presence across the nation’s nearly 50,000 community water systems, particularly among smaller utilities where compliance pressures remain significant and internal resources are often limited. He will work closely with Birchtech’s operations and R&D teams to identify client needs and connect them with practical, cost-effective solutions.

Management Commentary

“Charlie understands the realities rural water systems face every day, especially the challenge of meeting evolving PFAS regulations on a limited budget,” said Richard MacPherson, Birchtech Chief Executive Officer. “Charlie has spent years helping these systems prepare for emerging contaminants, and that experience is exactly what we need as we work to bring Carbon Rejuvenation™ to smaller utilities that stand to benefit most from its potential cost savings and operational efficiency. We expect that he will help us listen better, respond faster, and deliver solutions that truly fit the communities we serve, as we continue to scale our water business and drive long-term value for my fellow shareholders.”

“Charlie has worked on nearly every side of water treatment, from mine discharge sites to a city drinking water plant to helping rural systems tackle emerging contaminants,” said Dennis Baranik, Director of National Sales at Birchtech. “That kind of range is rare, and it means Charlie knows our customers’ challenges from the inside. We’re excited to put that experience to work for the communities he has served for years.”
