Mercury's Rising Impact
June 1, 2007By Constance L. Senior
This contaminant, a combustion byproduct of power plants, is increasingly polluting land and water through air-borne deposition
Mercury is getting a lot of attention, both in the popular press and in state and federal regulatory agencies. Combustion systems, like coal-fired power plants, industrial boilers, incinerators, and cement kilns, are sources of mercury emissions to the air. This article outlines the mercury emission regulations that apply to different combustion systems and the best demonstrated means to control these emissions from combustion sources. This article focuses on utility and industrial combustion systems because they are the highest emitters and face the greatest reductions and tightest scrutiny.
A Shock to the System

A new, stricter arsenic rule is starting to affect small and large water supplies
On Jan. 23, 2006, the arsenic rule was implemented with a new limit of 10 parts per billion (ppb) (the old standard was 50 ppb). The new rule has a broad reach; it affects large and small drinking water treatment systems, including non-community water supplies.
Water Quality Management 101
October 1, 2005By W. Wesley Eckenfelder, William Ney Hansard
A basic overview of the key concepts related to treating municipal and industrial wastewater
Over the past few decades there has been an increased awareness of the importance of water quality. Many municipalities and industrial facilities have upgraded or installed new technologies to meet the demand for clean water. Advances in water quality science show that further improvements are needed to ensure a plentiful water supply and to protect the natural environment.
Tackling Tough Contaminants
November 1, 2004By Russell A. Schuck, PG
Successful remediation of recalcitrant compounds starts with comprehensive site characterization
There are numerous case studies of failed remedial systems, which in turn can be linked to the remedial design team not fully understanding the site conditions. Often the most effective way to clean up these recalcitrant sites is source/migration control rather than intrusive remediation. The best solution can only be determined if the site is properly understood.
Arsenic Removal Arsenal

An overview of treatment options for successfully cleaning up contaminated drinking water supplies in compliance with the new stricter arsenic standard
The U.S. Environmental Protection Agency (EPA) has historically regulated arsenic at 50 parts per billion (ppb), but the agency will lower the maximum contaminant level (MCL) for arsenic to 10 ppb by 2006. Some states are even setting their own limits well below this level.
