For decades, granular activated carbon (GAC) has been recognized as an effective technology for removing organic chemicals in a variety of environmental applications. With strong demand for virgin activated carbon in both process and environmental applications, the use of carbon reactivation and recycling has become an increasingly important option for many companies that currently rely on activated carbon for their treatment needs.

Geographic information system (GIS) software represents less than 10 percent of the total GIS implementation cost in most cases, yet many people spend a lot of time selecting the best software for their GIS applications. This is actually a good thing, because the success of any GIS program largely depends on its users—who are not happy if they do not like their GIS software.

Throughout the world, thousands of stormwater pollutant removal systems are being installed in an effort to prevent watercourses from being polluted. As supply has risen to meet demand, a variety of proprietary, chamber-based systems have emerged, including hydrodynamic separators, which are designed to settle out and store sediments and associated pollutants, preventing them from being discharged to the natural environment.
