In October 2001, the US Environmental Protection Agency (USEPA) announced an initiative for additional
research and development for cost-effective technologies to help small systems
meet the new arsenic standard and to provide technical assistance to operators
of small systems to reduce compliance costs. As part of this initiative to assist
small community water systems (< 10,000 customers) in complying with the new
standard, USEPA's Office of Research and Development (ORD) proposed a project
to conduct a series of full-scale, long-term, on-site demonstrations of arsenic
removal technologies, process modifications and engineering approaches
applicable to small systems.
The objective of the arsenic removal technology demonstration projects was to:
evaluate cost-effectiveness of the technologies relative to existing technologies
and gauge simplicity of operation; evaluate the effectiveness of arsenic
treatment technologies under varying water quality conditions; compare
reliability; document operation and maintenance needs; and, characterize
arsenic wastes (residuals) and evaluate management practices.
The arsenic treatment technology demonstrations will be conducted at selected
water systems across the nation due to differences in water chemistry that exist
in various parts of the country. Because water chemistry is expected to affect the
performance of the treatment technology, the demonstrations will test some of
the same technologies at different sites. The demonstrations will last a full year.
This time frame provides for the gathering of operational information to fully
evaluate the performance of the technology over different temperature ranges
and to evaluate any seasonal factors that influence the performance of the
technology.
Water chemistry will be monitored throughout the process and information on the
simplicity of operation, energy costs, operator time and skills will also be
gathered. These demonstrations are to be conducted in real world conditions,
thus, USEPA will not be operating the technology. All operations will be conducted
by the operator or operators at the water system. USEPA and its contractor as well
as the technology vendor will support the water system throughout the process. Includes table.
