AECOM awarded USACE Baltimore District contract to deliver environmental services

Key Terms

environmental remediation technical

Environmental remediation is the process of identifying, cleaning up, and managing pollution or hazardous materials at land, water, or air sites to make them safe for people and future use. For investors it matters because cleanup can create large, sometimes hidden costs or legal liabilities, but successful remediation can also unlock property value or development opportunities—think of it like investing in a renovation that removes hidden damage and makes a building saleable.

pfas medical

PFAS are a group of human-made chemicals used in many everyday products, such as non-stick cookware, water-repellent clothing, and food packaging, because they resist heat, water, and grease. They are often called "forever chemicals" because they do not break down easily in the environment or the human body, potentially leading to health concerns. For investors, the presence of PFAS-related risks can impact companies’ reputations, legal liabilities, and future costs.

in-situ technical

In-situ means located or occurring in its original place, often used in medicine to describe abnormal cells or a treatment that stays in the tissue where it began rather than spreading or being removed. For investors, the distinction matters because an in-situ condition or therapy can imply different clinical risks, regulatory pathways and costs—similar to fixing a problem on the spot rather than taking the whole thing apart—which affects development timelines, approval chances and potential market size.

radiological materials medical

Radioactive materials are substances that emit energy in the form of particles or rays and are used in medicine, energy, industry and research—think of them as tiny, invisible batteries that can reveal images or power processes. Investors should care because their use triggers strict safety rules, specialized handling, disposal costs and potential liability, all of which can affect operating expenses, regulatory approvals and the value of companies that produce, use or transport them.

predictive modeling technical

Predictive modeling uses data and computer algorithms to estimate what is likely to happen next—like a weather forecast for business outcomes. By spotting patterns in past performance and current indicators, these models project sales, risks, customer behavior or other metrics that matter to investors. The results help investors weigh potential returns and risks, compare scenarios, and make more informed decisions faster than relying on intuition alone.
