Characterization of Soil, Groundwater, Surface Water, Sediment & Air Home Insights Publications DyeLIF™: A new direct‐push laser‐induced fluorescence sensor system for chlorinated solvent DNAPL and other non‐naturally fluorescing NAPLs This article describes how DyeLIF™ can provide hi-res, 3-D subsurface mapping of nonaqueous phase liquids (NAPLs) in the subsurface. At facilities with subsurface contamination, what other chemicals may your workers be breathing? Mathew Raithel’s AIHce presentation explored overlooked vapor intrusion hazards in the workplace.

Hidden in plain sight: Don’t let asbestos in soil derail your construction project Here are four tips on when to check for asbestos-containing material in soil on your construction project and what to do when you find it. New applications of CSIA for quantifying 1,4-dioxane biodegradation Technical Expert Peter Bennett was the lead author on the innovative study, published in Environmental Science & Technology Letters. Spatially averaged, flow-weighted concentrations – a more relevant regulatory metric for groundwater cleanup Murray Einarson advocates for the use of a new standard for groundwater cleanup in place of maximum contaminant levels. How you can cut costs and strategically address environmental challenges on campus What is the most effective way to approach the semi-privatized regulatory environment for property development? Here are seven things you can do. Direct push optical screening tool for high-resolution, real-time mapping of chlorinated solvent DNAPL architecture The tool is a new site characterization technology that facilitates 3-D delineation of residual chlorinated solvent DNAPL in the subsurface. 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. 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. Development and testing of a field screening method based on bubbling extraction and photoionization detection for measurement of benzene and total VOCs Peter Bennett and Murray Einarson discuss a new screening method to complete a site conceptual model and analyze groundwater from monitoring wells. Insights from Battelle’s Ninth International Conference on Remediation of Chlorinated and Recalcitrant Compounds Michael Basel and Paul Tornatore discuss industry trends from Battelle’s Ninth International Conference on Remediation of Chlorinated and Recalcitrant Compounds.
