Water Quality and Infrastructure

ERG’s water quality and infrastructure practice answers vital questions and provides cost-effective solutions to preserve and improve the nation’s waters. Our engineers and scientists are skilled at characterizing point and non-point source discharges, evaluating wastewater treatment infrastructure, and assessing and modeling the quality of surface waters and associated impacts to human and ecological receptors. We develop treatment options, best practices, and policy recommendations and provide technical assistance to communities in addressing water pollution problems. ERG’s water resource experts help clients implement water conservation programs and manage water resources. We develop product specifications and certification programs for water-efficient products. In addition, we assess the effectiveness of programs and recommend policies to better balance competing demands on water resources, including wetlands, coastal shorelines, and our nation’s rivers and groundwater. We routinely help our clients develop innovative solutions to meet new challenges and priorities, such as emerging contaminants and climate change impacts.

Solving today’s complex environmental challenges is a daunting task. It requires the delicate balancing of many competing factors, from cost and convenience to public health protection and resource allocation. At ERG, I am fortunate to be able to work on projects that get to the core of this balance, surrounded by clients and colleagues who are equally passionate about finding mindful, objective solutions for our complex world.

Deb Bartram

From an early age when I volunteered to clean up trash in local waterways, I’ve been passionate about improving water quality. I’m excited about innovative options for controlling industrial discharges and enjoy the constant challenge of finding and applying ever more cost-effective and environmentally beneficial solutions.

Chuck Durham

Three decades as a regulator and contractor to regulators has convinced me of one thing. We are more likely to save and preserve our natural resources by educating everyone on the impacts they can have, both positive and negative, than by simply punishing people for past sins. That said, enforcement is sometimes a necessary tool for education.

Jennifer Ferrando

Continual change in natural and political systems means there can be no perfect solution to water quality protection. However, we can continue to move in a productive direction by listening, questioning, and striving to understand the complexity of the issues we address and the interconnectedness of competing priorities. I enjoy working with my clients to seek a balanced approach that prioritizes water quality protection while respecting the needs of all stakeholders.

Wes Ganter

Protecting and restoring water quality has been my career-long mission. I feel so fortunate to have had great mentors, colleagues, and customers, and opportunities to serve throughout the U.S. and abroad. Most importantly, I truly appreciate  the privilege of mentoring a new generation of water quality professionals. Watching my company, PG Environmental, grow, thrive, and ultimately find such a perfect match with ERG has been equally rewarding. Looking forward, I am excited to tackle the water quality issues of the future.

Gregory Mallon

I started college in upstate New York just as acid precipitation was becoming a significant environmental concern. Through my studies of aquatic ecology in the nearby Adirondacks, I learned firsthand how devastating its effects on water quality and aquatic life could be and was determined to do something about it. That determination launched my 40+ year career as a water quality manager working to protect and preserve our nation’s precious water resources.

Arleen O'Donnell

I cherish the connection with nature I feel from the strength of the ocean, the run of a river, the serenity of a lake, the intensity of estuaries, and the magic of vernal pools. It’s from this sense of appreciation that I apply my knowledge, experience, and passion to protect and restore the ecological integrity of water resources.

Danny O’Connell

The operation and maintenance of water and wastewater utilities requires a clear understanding of the diverse variables unique to each facility. I enjoy interfacing with utilities operations and management teams to evaluate these variables and help create conditions or approaches that enable water treatment and management systems to perform at their highest efficiencies.
