  • Georgia’s innovative approach to CMOM implementation - Georgia member association & state collaborate to improve SSO approach

    In 1998, the Georgia Environmental Protection Division (EPD) adopted a Zero Tolerance Policy for the area in and around metro Atlanta to address sanitary sewer overflows (SSOs). This policy required EPD to take an enforcement action against utilities for any SSO, regardless of the size, volume, or cause of the release. In response to this enforcement-based SSO strategy, at the request of its ...

  • Portable IR Analyzers Provide Petroleum & Wastewater Industries with Accurate Oil Content Measurements

    Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on off-shore and on-shore drilling platforms for well over 45 years. U.S. EPA methods 418.1 and 413.2 were used extensively on a worldwide basis until the Montreal Protocol called for Freon (the solvent used in the analysis) to be phased out. Infrared analysis using tetrachloroethylene (perchloroethylene) is ...

  • Rapid on-site analysis of fats, oil and grease (FOG)

    It is estimated that 23-28% of Sanitary Sewer Overflows (SSOs) are due to Fats, Oils and Grease (FOG) or as much as 19 million gallons from 1998 to 2001 (State of North Carolina, 2004). Our increasingly mobile society has led to a decrease of cooking at home and a significant growth in the commercial food sector. This, on top of other industries such as metal processors, meat packers, cosmetic ...

  • What the Wastewater Industry can learn from the Petroleum Industry when it comes to measuring oil in water

    I recently read a comment in the Steve Jobs biography by Walter Isaacson that different divisions within a company do just what the name implies—divide a business.  Integration across and communication between the departments was essential to smooth functioning product.  I think the same is true in the analytical analysis/measurement world—there seems to be a divide in ...

  • What too much water can do to your collection systems

    In areas with a high water table, or for cities more prone to flooding, your underground infrastructure can become inundated with groundwater and stormwater. And despite stormwater systems being built for this type of collection, there are a number of things that can go wrong for both types of collection systems underground—and above ground—that can lead to contamination or degraded ...
