Risk Assessment Home Insights Publications Why being “OSHA legal” isn’t enough OSHA’s 1970 chemical exposure regulations are still in place. Michael Pardus shows why it’s important to look beyond them. At facilities with subsurface contamination, what other chemicals may your workers be breathing?

Improve remediation success and reduce portfolio risk using a Lean approach This SlideShare explores how a “Lean” approach can help portfolio managers better understand and quantify remediation risks, which ultimately reduces risks and costs. Risk-based engineering for trenchless installation projects The design and construction of projects using one or more trenchless installation methods is more than just a line on a piece of paper. EPA releases updated toxicity values for Benzo(a)Pyrene: what you need to know EPA has published higher risk-based screening values for benzo(a)pyrene. Find out how this might affect your projects. Emerging contaminants in Arizona water: a status report Haley & Aldrich staff worked closely with ADEQ's Advisory Panel to produce this report on emerging contaminants in Arizona’s water supplies. Regulatory guidance: Risk assessment and the CCR rule This publication outlines four opportunities to use risk assessment as it relates to the CCR Rule to demonstrate the protection of human health and the environment. Developing resilience: Living with water strategies for Greater Boston This report on resiliency strategies related to sea level rise and coastal storms in Greater Boston centers on five overarching questions. Overview of depth‐discrete multilevel groundwater monitoring technologies: focus on groundwater monitoring in areas of oil and gas well stimulation on California Describes key multilevel systems for groundwater monitoring in areas of oil and gas well stimulation, as required by California law. Bioavailability: a critical, yet often overlooked, metric in remediation decisions An often-overlooked risk assessment for cleaning up contaminated sediments is bioavailability, which can substantially reduce project scope and costs. Ground improvement and building support: what is it and who is responsible? The increasing use of ground improvement for building support brings with it potential risks that must be addressed.
