About Us

We research, develop, and commercialize innovative soil and groundwater remediation solutions through university and professional relationships in order to meet the increasing technological demands at contaminated sites. Our proven technologies help our clients reduce uncertainty, minimize risks, and achieve cost-effective results.

We are dedicated to supporting our clients by delivering outstanding customer service every day. Tersus Environmental is not focused on a specific technology and offers the right solution for your specific site needs. We look forward to helping you develop the most cost-effective and optimally performing remediation approach.

Our Values

As a customer-focused company, Tersus's steadfast mission is to ensure our clients are clients for life. Our corporate culture is based on the following core values::

1Customer service: understanding the needs of each client (internal and external) and striving to exceed their expectations. We listen to what each client wants and then do everything we can to deliver it in a timely fashion.

2Loyalty: we work collaboratively with Tersus associates, partners, suppliers, and clients to solve problems and achieve goals.

3Quality: no matter how effective our services, processes, and performance, we are dedicated to constantly improving. We strive for excellence in our product and service offerings. We routinely benchmark our own operations and re-align our processes to meet the high standards we set for ourselves.

Leadership

Always innovating

Our clients’ needs are constantly changing, so we continually seek new and better ways to mitigate their risks and deliver technology-based solutions to manage complex, challenging environmental liabilities. We accomplish this by bringing new talent into our firm, acquiring or licensing patented technologies, and developing new technologies either in-house or in conjunction with academic institutions and other companies. No matter the challenge, we focus on delivering cost-effective and sustainable solutions to achieve lasting results.
