Founded in 1995 by Mr. David Allan Klunk, a renowned Johns Hopkins scientist, CEL began with a clear mission: to ensure that everyone, regardless of where they live, has access to safe, clean drinking water. With this goal in mind, Mr. Klunk built CEL on the foundations of scientific excellence and unwavering trust. Over the years, CEL’s motto, “Built on Science…Growing on Trust,” has proven to be more than a slogan—it is a philosophy that continues to guide our every action.

In 2023, CEL was acquired by GHP Consulting and Testing LLC, a New Jersey-based company with over 15 years of industry experience. This partnership enables us to expand our services and continue delivering cutting-edge testing and calibration solutions throughout Maryland and the East Coast. With our combined expertise, we remain committed to helping our customers ensure the quality and safety of their environment, protecting public health every step of the way.

Our growth over the years is reflected in the broad spectrum of clients we now serve, including government installations, the Department of the Army, city public works departments, private water companies, public school systems, and even Universal Studios, who utilized our services during the filming in Baltimore for For Richer or Poorer. No matter the client, our priority remains the same: to provide superior testing and calibration services that protect the health and well-being of our communities.

As we continue to grow, we remain dedicated to ensuring the highest standards of service and care for our clients. Let us help you protect what matters most—your health and safety.
