A Guide for Public Water Systems
-------
Introduction
On January 22, 2001 EPA revised the arsenic standard to 10 parts per billion (ppb). All public
water systems must comply with this 10 ppb maximum contaminant level (MCL) by January
23, 2006. Some systems will have to install treatment for arsenic removal in order to meet
the revised MCL. For more compliance information, please visit http://www.epa.gov/
safewater/arsenic.
There are a number of technologies to choose from, and numerous engineering firms and
treatment vendors who can help you with treatment selection, installation, and operation.
Choosing the right technology and firm for your system can be a confusing and time-
consuming process. The information in this brochure will help you navigate through the
process of selecting the most appropriate treatment for your system
This guide will provide you with:
* An overview on the long-term, chronic health effects linked to drinking water that contains
arsenic.
* Basic information on available treatment technologies for arsenic removal.
» Important questions to ask engineering firms and vendors when looking for the best
treatment for your system and the best firm to design and install the technology.
* Information on estimating treatment installation and operation costs and sources of
additional information on arsenic and arsenic removal.
By working through the handouts in this brochure and by reading the questions and answers,
you will be able to more confidently choose an engineer or a vendor that you trust to help you
make the best choices for your system.

Though most of the waste streams will not be hazardous, ask for certific
that the waste will pass the Toxicity Characteristic Leaching Procedure t
(or Waste Extraction Test, for systems in California). Have the vendor
identify any contaminants that treatment will remove that may cause the
to be characterized as hazardous. Disposal of hazardous waste is more
difficult and costly.

The wastes produced by the technology can sometimes be very difficult
handle and dispose of. This information could be a major determining f;
in your treatment selection. You should be sure that you have a means
through which to dispose of the waste.

Each treatment technology is somewhat different. With some, you may

the media. You need to know what chemicals, if any, will be needed; tf
costs, avaikbility and handling/safety requirements. Any chemical that is
added to the drinking water must have NSF 60 certification.

If the equipment is adaptable you will not be tied to one supplier.
For example, if the vessel has a typical EBCT, then the repkceme
media can be from any supplier that can provide the treatment wil
the same EBCT. Also, with some modification, adsorptive media
treatment systems could be adapted to coagulation/filtration.
