   Water Contaminant Information Tool's

          (WCIT) Latest Growth Spurt:
Contaminant Database Adds 11 Substances

U.S. EPA's Office of Ground Water and Drinking Water (OGWDW) has
announced an expansion of WCIT, adding 11 contaminants to the
online tool.Most are chemicals regularly used in drinking water and
wastewater treatment processes, although two substances (dioxins
and furans) were added due to their toxicity and use or occurrence.
Through accidents,  natural disasters or intentional acts,  these 11
substances have the potential to enter water systems or contaminate
source water. The 11 new WCIT contaminants are:
     aluminum sulfate

     ammonium hydroxide

     chlorine dioxide



                                 sodium hydroxide

                                 sodium hypochlorite

                                 sodium sulfite

                                 sodium thiosulfate
    • hydrogen peroxide

This addition brings the total to 113 contaminants listed in WCIT
that include full profiles — with medical information, early warning
indicators, drinking water treatment and several other categories
of valuable information. For more than 700 additional substances,
there are details about methods — including both field and laboratory
methods — with method descriptions, uses and, when available, links
to the full methods. EPA will continue to add additional substances
to WCIT (biotoxins, chemicals, pathogens, radioisotopes, etc.) to
ensure that the tool remains  a valuable source of information for
the  water sector.
           WCIT Online Training

Never tried WCIT? Or haven't used it in a while?
Or maybe you would like a refresher on how to use it. Then you
should take advantage of the free online training available for WCIT.

During the upcoming fiscal year, EPA will be offering hands-on
WCIT training. This special training lasts about one hour. It provides
an introduction to WCIT content and guidance on how to use the
tool. By the end of the one-hour training session, you will be able
to identify contaminant and method data in WCIT, and use most of
the tool's features — such as the search,  contaminant comparison
and risk assessment functions. Both Internet and telephone access
are needed  for this free training.

If you are interested in the training,  send an email to WCIT@epa.
gov. You will be contacted with the new fall training schedule.

      WCIT Incorporates
   Contamination Response
      'Expert System' Tool

As part of continued enhancements of the
WCIT, EPA has incorporated a powerful
resource to assist water utilities and other
WCIT users in planning or executing their
response to a drinking water or wastewater
contamination incident. Chemical biologi-
cal and radiological (CBR) Advisor, a tool
within WCIT, is an interactive, expert system
that supports real-time responses to con-
tamination incidents, as well as serving as
an individual or group training tool.
CBR Advisor is based on the Response
Protocol Toolbox (RPTB), a comprehensive
guide for responding to drinking water con-
tamination threats and incidents that was
developed by EPA's OGWDW.
The modules of the RPTB cover key con-
tamination response priorities, including:
  • Contamination threat management
  • Site characterization and sampling
  • Public health response
  • Remediation and recovery

Specific RPTB topics covered include:
  • Classifying threat warnings
  • Conducting initial threat evaluations
  • Collecting, packaging and shipping
   hazardous samples
In WCIT, CBR  Advisor operates in a split-
screen format. The left-hand side follows
an intuitive Q & A approach. This enables
users to  get quick answers to emergency
response questions, and link to documents
and forms that will assist in an emergency
response or a training exercise. The right-
hand side operates in tandem, allowing
users to  drill down  more deeply on topics
on the left side.
To access CBR Advisor, after logging in to
WCIT, click on the "Tools" tab at the top of
the page. Then click the link for CBR Advi-
sor once you reach the "Tools" Web page.

 Haven't Logged In Lately, or Forgot

      Your Password? No Problem!

Haven't logged into WCIT lately because you forgot your
password or user name?

If you haven't visited recently, it's possible that your pass-
word has expired. If it has, or if you have forgotten it, it's
easy to create a new password — and takes only a minute

              WCIT Challenge
Read the  scenario below and use WCIT to answer the
questions. Send your answers to The
first several responders with the correct answers will be
acknowledged in the next WCIT Update.

SCENARIO: The Ohio  River Valley is impacted by high
winds, heavy rain and several tornadoes resulting from
a fast-moving storm system. During the nighttime, an
unmanned river barge  on the Ohio River loaded with al-
dicarb escaped from its mooring and rams into a bridge
just above the water intake for a medium-sized city. The
collision results in a large gash in the barge below the
water line. Hours pass  before anyone realizes the extent
of the damage, allowing  much of the barge contents to
spill into the river.

QUESTIONS: What is the  chlorine to aldicarb ratio needed
for complete removal? Less than optimal chlorination
results in chlorinated  aldicarb sulfone  and chlorinated
aldicarb sulfoxide. How does this affect the toxicity? What
is the hydrolysis half life  of aldicarb in raw water?

To take the challenge,  log into WCIT at https://cdx.epa.
gov/. Good luck!

WCIT Becomes  Everyday
Companion for Lab Manager
                   Fairfax Water, outside of our
                   nation's capital, is one of the
                   largest water utilities in the
                   nation, providing drinking
                   water to  nearly 1.7 million
                   people in Northern Virginia. For
                   Melissa A. Billman, Manager/
                   Water Quality Laboratory &
                   Regulatory Compliance, WCIT
  Melissa A. Billman    has become a valuable tool
for operational activity as well as for emergency
response training and exercises at the utility. "WCIT is
an easy-to-use, robust tool -very logical and well laid
out," she says. "It provides technical expertise, and
the information is authoritative and understandable,
which provides a level of confidence when making

For Fairfax Water, Ms.  Billman has used WCIT to
research impacts of pesticide use within the utility's
service area watershed, to shape response to
petroleum-related spills in the Potomac River (one
of the utility's sources of raw water), and as a tool
to support emergency response exercises.  In 2013,
Fairfax Water was one of the two water utilities
participating in an EPA Office of Water (OW) Full-Scale
Exercise to test laboratory response capabilities for
a hypothetical drinking water contamination incident;
Ms. Billman  used WCIT to research contaminants
planned for the scenario.

Ms. Billman  has been a WCIT  user for about four
years. She was introduced to the tool at EPA OW's
Water Laboratory Alliance (WLA) Security Summit in
2009. She and herstaffsubsequentlytookadvantage
of WCIT's free online training (see article on page
1). "That's when we realized how many tools WCIT
provides and, overall, how  useful  it is for a water
utility," she says. Ms. Billman especially values WCIT's
drinking waterfocus, such as how it provides details on
parameters that would be affected by a contaminant
and the analytical methods and online water quality
testing needed to detect the contaminant. In addition,
she likes the ability in each contaminant profile to
switch between information categories (such as fate
and transport, drinking water treatment) with just one
click. "The Public Information Officer page for each
contaminant  also is very helpful," she says.
