Arsenic
Removal:
Assisting
Small Water Systems
Through New Environmental Technologies
|
The
NSF International (NSF), in cooperation with the USEPA,
operates the Drinking Water Systems (DWS) Center, and is coordinating
Environmental Technology Verification (ETV) of new and innovative arsenic
removal technologies. This effort will help small community water systems meet
the new arsenic maximum contaminant level (MCL) of 10 micrograms per liter.

Terminology
Understanding . . . |
| A goal of
verification
testing
is to enhance and facilitate the acceptance of small drinking
water treatment equipment by state drinking water regulators and
consulting engineers. It also reduces the need for testing
at each location where the equipment might be used.
An
NSF-qualified
Field Testing
Organization (FTO), such as
Gannett Fleming, works with manufacturers to conduct verification
testing under NSF-approved protocols.
Equipment
verification doesn't mean that the equipment is “certified” by
NSF or “accepted” by the USEPA.
Rather, it recognizes that equipment performance has been
determined and verified by these organizations for those
conditions tested by the FTO.

Pennsylvania
Initiatives
The
ETV DWS Center and the PADEP Innovative Technology Unit have agreed to develop a
cooperative arsenic treatment technology study of adsorptive media. This
program involves three Pennsylvania utilities (representative of other state community water systems)
that have arsenic in their source water exceeding the
MCL.
Gannett
Fleming, one of only 11 NSF- qualified FTOs,
was selected to conduct verification
testing at the three sites.

Inc. (with Alcan
Chemicals) Arsenic
Adsorption Media Filter System
Water System:
Orchard
Hills Water Treatment Plant
Location:
Shermansdale (Carroll Township)
Dates:

Description:
The DWS Center evaluated the performance of the
Kinetico Inc. and Alcan Chemicals Para-FlowTM PF60 Model
AA08AS with Actiguard AAFS50 system, which is an arsenic adsorption
media filter used in drinking water treatment system applications.
Gannett Fleming's verification test evaluated the ability of the
absorptive media to remove arsenic from drinking water.
NSF
provided technical and quality assurance oversight of verification testing, including an audit of nearly 100% of
the data.
Gannett
Fleming provided all necessary logistical support, established a
communications network and scheduled and coordinated all participant
activities. The firm performed all field monitoring work including
sampling and on-site water quality analyses, conducted a data analysis
and prepared a peer-reviewed report. Gannett Fleming also ensured that
location and feed water
conditions enabled verification testing to meet its stated objective. |
