U.S. EPA Announces Actions to Combat PFAS Contamination

MYCELX Technologies Corporation (AIM: MYX), the clean water and clean air technology company, notes the announcement by the United States Environmental Protection Agency ("EPA") regarding a comprehensive plan to tackle PFAS contamination, focusing on prevention, accountability, and support for affected communities.

Key actions cited in the announcement include appointing a PFAS agency lead, developing effluent guidelines to prevent PFAS from entering water systems, enhancing scientific research and detection, and creating a liability framework to ensure polluters bear responsibility for the remediation costs.

MYCELX is of the view that the announcement will lead to increased activity and investment in the PFAS remediation market.

Jim Weidler, MYCELX Director of Business Development - PFAS, commented:

"Most participants in the PFAS remediation industry have been waiting for an update and action plan from the EPA on how this critical market will evolve under the new administration. The establishment of a clear liability framework, which protects citizens while punishing polluters is a significant step forward, and the expansion of additional effluent guidelines will enable companies at the leading edge of the PFAS remediation market, such as MYCELX, to continue to roll out their technological offerings.

MYCELX will begin a wastewater effluent PFAS polishing trial in the next couple of weeks and has devoted considerable time and investment into becoming one of the leading PFAS remediation businesses in the United States. Multiple opportunities exist for PFAS treatment companies like MYCELX to secure new business and partnerships due to the EPA's expanded regulatory and enforcement agenda and we look forward to updating the market on the Company's advancement with this over the coming months."
