Executive Summary
Bench-scale experiments were conducted to measure the response of water quality parameters to
contaminants that are potential threats to the drinking water supply. The experiments were
conducted in beakers at the United States Environmental Protection Agency (U.S. EPA) Test
and Evaluation (T&E) Facility in Cincinnati, Ohio. Five different types of finished waters from
four municipalities within the United States were evaluated. Numerous studies have evaluated
the response of water quality parameters to injected contaminants for a specific water matrix
(Hall et al., 2007). However, end users of the data have expressed concerns about whether a
utility with different source waters or treatment regimes would experience the same dose
response as EPA observed. Therefore, more data comparing these responses across various
treated waters are provided in this data set to address these concerns. The data are provided in
excel spreadsheets in the appendices of this report. An example spreadsheet explaining each data
field is also provided for nicotine. The water community can use these spreadsheets to select the
source water and treatment most representative to their utility and build specific dose response
curves. An example dose response curve for oxamyl is developed and presented from this data in
Section 3. Optimally, these dose response curves can be used to infer a contaminant
concentration due to a given deflection or change in a water quality parameter.
This data set was prepared in support of the EPA's Water Security Initiative, which is being
implemented by the Office of Water. This data set was summarized and presented at the 2010
American Water Works Association Water Quality Technology Conference in Savannah,
Georgia (Allgeier et al., 2010). This data set provides response data for chlorinated and
chloraminated surface waters and for filtered and unfiltered treated waters. It also provides data
for chlorinated groundwater.
Sixteen selected chemical, biological and radiological (surrogate) contaminants were used at
varying concentrations. The water quality parameters of free and total chlorine, total organic
carbon, pH, specific conductance, oxidation-reduction potential, and ultra violet- visible light
(UV-Vis) absorbance were evaluated. The data are presented in Excel® (Microsoft Inc.,
Redmond, WA) spreadsheets. An example spreadsheet for nicotine explaining the data fields is
provided in the Appendices to this report
In general, the data showed that the type of disinfectant, treatment process, or water source did
not greatly affect the water quality parameter response to the injected contaminants. There was
an overall slower parameter response time for chloraminated waters than for chlorinated waters.
Free and total chlorine along with total organic carbon (TOC) were the most responsive to the
wide range of contaminants tested. Also, the parameter of UV-Vis absorbance was a useful
substitute for traditional UV persulfate-based TOC detectors and was not affected by varying
water types. Per the detection thresholds defined in section 3 of this report, the data sets for all of
the waters tested showed consistently that the TOC response via the UV persulfate method was
able to detect 62.5 % of the injected contaminants while UV-Vis surrogate TOC was able to
detect 37.5 %. Free and total chlorine were also able to detect 62.5 % of the contaminants.
However, the true value of this data set is the afore mentioned ability to develop specific and
representative dose response curves.

1 Introduction
Concern over the risk of deliberate
contamination of drinking water
systems, and research aimed at
mitigating this risk, has intensified with
the spate of global terrorist activity. The
U.S. Environmental Protection Agency
(EPA) has devoted research efforts to the
early detection of contaminants within a
drinking water system. Data in this
report describes the response of water
quality parameters to the injection of 16
selected chemical, biological, and
radiological (surrogate) contaminants in
a laboratory. The data were generated in
order to build parameter response curves
for various types of drinking waters with
an ultimate goal of improving event
detection. Though several studies have
been performed that provide
contaminant response data for a single
water matrix (Hall, et al., 2007 and
Szabo et al., 2008), the question of
applicability to other finished waters is
often raised. End users of the data have
expressed concerns about whether a
utility with different source waters or
treatment regimes would experience the
same dose response as EPA observed.
The objectives of this study were to:
• Evaluate water quality parameter
response times using five test
waters and 16 water security
contaminants under controlled
conditions.
• Develop tabular summaries,
graphical representations and
empirical relationships for each
combination of water source,
contaminant, and water quality
parameter. The data can be used
to interpolate or infer responses
from similar water types and
contaminants. Dose response
curves can be built from this data
which will allow the end users to
choose the water type and
treatment method most similar to
their utility. An example dose
response curve is developed and
presented for oxamyl in Section
The goal of this data report is two-fold:
(1) to summarize the response data for
the aforementioned project and (2) to
provide the data and data collection
methods to the broader research
community. This document, containing
both the data collection methods and the
data, is available online through the
National Homeland Security Research
Center (NHSRC) website
(www.epa.gov/nhsrc/). Therefore, any
publications generated from the
aforementioned project can reference
this data and the data is easily accessed.
In addition, the data provided in this
open format is accessible to and
available for use by other researchers in
the fields of event detection algorithms,
data modeling or water quality.

2 Materials and Methods
2.1 Test Samples
Five different test waters were collected
for this experiment from four different
municipalities (see Table 1). The
collected water was shipped overnight
on ice to the laboratory. All the collected
water was stored in the refrigerator until
use. The water to be used in the
experiments was removed from the
refrigerator on the night before the
experiments to bring the water
temperature to room temperature
(~20°C). The water removed from the
refrigerator sat in the Organics
Laboratory, where the overnight shift of
room temperature is less than 5 °C.
The test waters from these 4
municipalities cover a broad range of
variable and are representative of most
treated drinking waters within the United
States. Waters number 1 and 5 are
supplied from rivers. Waters number 3
and 4 are supplied from surface water
lakes and reservoirs. Water number 2 is
supplied from groundwater. Waters
number 1, 2 and 3 are chlorinated and
waters 4 and 5 are chloraminated.
Waters number 3 and 4 are unfiltered.
Water number 1 has conventional
treatment followed by granular activated
carbon filtration.

2.3 Testing procedures
The testing was conducted under a fume
hood. Approximately 1550 milliliters of
each water matrix to be tested was added
to a 2 liter test beaker on a spin plate as
per the test procedures listed below.
The purpose of the Day 1 testing was (1)
to prepare the control and test beakers
and (2) to then record WQ parameters
following injection of contaminants into
the water types.
The purpose of the Day 2 testing was to
ensure that the control sample without
contaminant added provided stable
readings the next day and that chlorine
decay due to exposure to air and light at
room temperature had been completed. It
was also an important data point for the
test beaker with the contaminant added
because it provided a 24 hour sample.
The injection testing and sampling was
performed over a relatively short time
period of approximately 45 minutes.
Previous studies have indicated that the
water quality parameters react quickly
with added contaminants, but not in all
cases, especially with chloraminated
waters. However, the 24 hour sample
provided some insight into contaminants
with delayed reaction kinetics.

Table 3 lists the contaminants that were
evaluated in this study. The water
quality responses to each contaminant
were measured at five concentrations
between zero and a reference
concentration. The listed reference
concentration represents the maximum
concentration used for testing. If
measureable water quality responses
were observed at lower concentrations,
then the higher concentration injections

For the purposes of quantifying detection, certain thresholds needed to be established. In
other words, what minimum deflection of the response signal would be considered a
detection of a water quality event due to the added contaminant? The following detection
thresholds were established based upon historical data and experience with the water
quality sensors:
TOC UV persulfate method
UV-Vis absorbance (TOC surrogate)
Chlorine residual (free and total)
Conductivity
Oxygen Reduction Potential (ORP)
pH
0.2 mg/1
0.005 UVA units
0.2 mg/1
25 us/cm
50 mv
0.2 pH units
These detection thresholds and data sets provided in the attachments can be used to
develop response curves and compare sensor responses across varying water types. An
example of a typical response curve which can be developed is provided below.

Using the detection thresholds listed above and the attached data sets, it was observed
that the water type was not a major factor affecting the water quality response to the
study contaminants. The study results consistently showed the UV persulfate method
was better at detecting TOC than the UV-Vis method, with percent detections of 62.5 and
37.5, respectively. Free and total chlorine methods were also able to detect the study
contaminants 62.5% of the time.
