Principals and Management Staff

The principals, Phil Derrenbacher and Joe McLaughlin have over 60 years of combined experience in water and wastewater management. They complement the on-site staff to create an efficient and effective environmental facility. Our staff makes weekly reports about facility operations and meets frequently with VRI principals and managers to assess the effectiveness of operations and monitoring. Our team makes any adjustments necessary to optimize the facility, fulfilling the client’s and VRI’s objectives to meet or exceed all regulatory standards, all while reducing short and long-term operating costs.
