Transforming the future of engineering by highlighting female role models
Diane MacMillan is a chemical engineer who specializes in remediation, focusing on Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) programs to manage the cleanup of sites contaminated with hazardous substances and pollutants. She joined Tetra Tech in 2001 and applies her experience to the environmental management market. Diane earned a Bachelor of Science in Chemical Engineering from the University of Wyoming.
For more than 40 years, we have partnered with industry, academia, and allied governments to make the world a cleaner, safer, and more secure place. We have performed environmental cleanup work at more than 500 contaminated sites across the world, managed operations at vital national security projects, and helped the U.S. and other countries reduce threats posed by weapons of mass destruction. Their results will benefit people and the environment for centuries to come.

Efforts to reduce nutrient levels are shifting and becoming more widespread as water and wastewater utilities work to improve effluent and adhere to regulations
Nutrient pollution and the resulting excess of nutrients in waterbodies continues to plague aquatic environments around the world, threatening waterways, fish and plant life — and even public health. The runoff of phosphate and nitrogen from farming, stormwater, wastewater treatment plant discharges and other sources into waterbodies continues to unbalance ecosystems, resulting in toxic algal blooms and hypoxic dead zones.
Decked out in waders with a mission of finding macroinvertebrates and minnows in the Clinton River, FCA Environment, Health and Safety (EHS) Lead Dave Jump gets knee deep with Bowers Academy high school students to create the next generation of “stream leaders.”
Plant marks milestone in international treaty obligations
RESTON, Va., June 24, 2019 /3BL Media/ - With the destruction, in a sealed chamber, of one World War II-era projectile loaded with mustard agent, a Bechtel-led team in Kentucky has begun eliminating the final stockpile of U.S. chemical munitions, bringing the nation closer to its goal of permanently eradicating the weapons.
Take a closer look at the public spaces surrounding your community’s park and recreation areas. If you look carefully, you’ll probably notice hundreds, if not thousands, of pieces of cellulose acetate plastic — better known as cigarette butts — littering the sidewalks and parking lots.
Keep America Beautiful®, the nation’s leading community improvement nonprofit organization, has taken aim at aggressively reducing cigarette litter and beautifying communities through its Cigarette Litter Prevention Program® (CLPP), which launched in 2002.
If you've been wondering what people mean when they talk about a Green New Deal, today's episode of Sea Change Radio should help. This week we air the second half of our discussion with technologist Ramez Naam. Last week Naam shared some of the specifics of the Green New Deal. This we talk about the best way to pitch any plan to the American public, whether a measure for restricting individual consumption ought to be included in the plan, and the importance of considering vulnerable populations around the globe when crafting sound climate policy.
Has the carbon tax been effective at lowering global GHG emissions? In a word no, but maybe it’s not the tax itself that’s flawed but rather that it’s never been properly targeted at the people who are holding back progress.
