For over 30 years, ERG has provided a full suite of services, across all industrial sectors, to help clients design, implement, and assess strategies and programs to prevent, reduce, and manage toxic chemical releases and exposures. Our engineers, environmental scientists, risk assessors, and industrial hygienists evaluate industrial processes and products to identify chemicals that are manufactured, processed, and used, and then characterize the associated human health and environmental risks from potential releases and exposures. They also provide full-spectrum support to help clients understand, select, and implement pollution prevention and risk management options to mitigate unreasonable risks. For example, our specialists identify alternative manufacturing processes; identify and characterize green engineering, green chemistry, and treatment technology options; and evaluate recycling and end-of-life management strategies. For clients interested in understanding the value of regulatory or voluntary efforts, ERG economists evaluate the costs and benefits of toxic chemicals management, reduction, and prevention programs.

I always appreciate when our government clients ask us to help them quantify the benefits and costs of actions they are considering. The more complex assignments, such as accurately characterizing behavioral changes under multiple compliance scenarios, put a premium on our creativity and experience.

The synergy between my enforcement and chemical evaluation work is invaluable. Because of the overlap, I routinely apply my skills and knowledge from one field to the other. This makes my work more efficient and enables me to approach it more holistically.

My experience has taught me that engineering and environmental protection go hand-in-hand. They do not need to hinder each other, but rather should work synergistically to continuously improve our world and the environment we live in.
