EOS Remediation and Microbial Insights invite you to a webinar: Biomarker-based Tools to Validate 1,4-Dioxane Biodegradation
1,4-Dioxane is an emerging contaminant of concern, commonly associated with chlorinated solvent plumes. Due to its high solubility in water, resistance to biodegradation under natural conditions, and ineffective removal by technologies, 1,4-Dioxane tends to persist in wastewater and groundwater. 1,4-Dioxane biodegradation, catalyzed by monooxygenase enzymes, has been established in laboratory ...

ASTM D4129 - 05(2012) Standard Test Method for Total and Organic Carbon in Water by High Temperature Oxidation and by Coulometric Detection
This test method is necessary because of the need for rapid reliable tests for carbonaceous material in waters and sediments. It is used for determining the concentration of organic carbon in water that comes from a variety of natural, domestic, and industrial sources. Typically, these measurements are used to monitor organic pollutants in domestic and industrial waste water. When a ...

Harmful polycyclic aromatic hydrocarbons removed from soil using wastewater sludge and polyacrylamide
Wastewater sludge is widely used to remove toxic polycyclic aromatic hydrocarbons (PAHs) from soil, and yet the mechanisms underlying this process remain unclear. A new study reveals the extent of PAH removal following different treatments, and could provide a useful resource for those looking to diminish the effects that these pollutants have both on people and on the environment. PAHs have ...
