Treatment Technology Evaluation
Research in Treatment Technology Evaluation (TTE) is focused on several key problems that face the potable water industry today. These include the formation and removal of disinfection byproducts of both ozonation DBPs and chlorination DBPs, the removal of pathogenic protozoa, such as Cryptosporidia and Giardia, and corrosion control. Branch staff also engage in collaboratorive research with utilities, academic institutions, and consultants. Branch scientists provide technical support to the Office of Ground Water and Drinking Water, EPA regional offices, and state governments.
TTE projects are supported by a combination of administrative, chemistry, and engineering staff. The research is conducted in onsite laboratories and pilot plants as well as through grants, contracts, and cooperative agreements.
The scope of TTE research projects is often defined by the needs identified within other offices of the EPA, such as the Office of Ground Water and Drinking Water. Information learned by TTE scientists supports the development of EPA regulations and rules. Most of present research is tied closely to the Disinfection Byproducts Rule and the Information Collection Rule. Some research is focused on lead and copper rule compliance. It is important to consider all treatment technologies in terms of total water quality. Our branch is also interested in the special problems of small and medium size systems and the processes that are most amenable to those systems.
