Testing and verification of a bench top luminometer for detecting toxicity of wastewater effluent
was conducted as a joint verification project with the Danish Centre for Verification of Climate and
Environmental Technologies (DANETV), ETV Canada, and the United States Environmental
Protection Agency (U.S. EPA) Environmental Technology Verification Program (ETV). The testing
and verification satisfied the requirements of the Canadian ETV program, U.S. ETV program and
the ETV scheme currently being established by the European Union (EU ETV).
Environment Canada established the Canadian ETV program to provide credible information for
promoting the commercialization and market deployment of new environmental technologies, thus
helping to address environmental challenges efficiently, effectively and economically. Information
on the Canadian ETV program is available at www.etvcanada.ca.

The U.S. ETV program was established to facilitate the deployment of innovative or improved
environmental technologies through performance verification and dissemination of information.
The goal of U.S. ETV is to further environmental protection by accelerating the acceptance and use
of improved and cost-effective technologies. U.S. ETV seeks to achieve this goal by providing
high-quality, peer-reviewed data on technology performance to those involved in the design,
distribution, financing, permitting, purchase, and use of environmental technologies. Information
and U.S. ETV documents are available at www.epa.gov/etv.
DANETV was established by four independent Danish research and technology organizations and
is supported by the Danish Agency for Science, Technology and Innovation under the Danish
Ministry of Science, Technology and Innovation to provide environmental technology verification
for vendors of innovative water technologies. Information and DANETV documents are available at
www. etv-denmark. com.
DHI as DANETV Water Center performed the testing and verification in collaboration with ETV
Canada and the ETV Advanced Monitoring Systems (AMS) Center, managed by Battelle through a
cooperative agreement with the U.S. EPA.
VERIFICATION AND TEST DESCRIPTION
Testing and verification of the LUMIStox 300 Bench Top Luminometer took place between
January and April 2010. DHI personnel, with support from the vendor, HACH-LANGE,
coordinated and supervised testing. The testing took place in the DHI laboratories, H0rsholm,
Denmark. DHI operated the luminometer during testing. HACH-LANGE provided the product
(luminometer, thermal block and software), user manuals, and operating instructions for the tests.
The LUMIStox 300 Bench Top Luminometer verification test was performed simultaneously with
the verification test of the Eel ox Luminometer also from HACH-LANGE. ETV Canada, Battelle
and DHI jointly produced the verification protocol, test plan, process document and report
documents including this Verification Statement with input from HACH-LANGE and an
independent expert group.
The test program was designed to comply with ISO standard 11348-3: "Water quality -
Determination of the inhibitory effect of water samples on the light emission of Vibrio fischeri
(Luminescent bacteria test)", as well as the instrument manuals.
Stock solutions were prepared in 2% NaCl MilliQ water. Solid NaCl was added to wastewater to
obtain the salt concentration required for testing with the saltwater bacteria, Vibrio fischeri. Dilution
series were prepared with dilute saltwater (2% NaCl).
Ten test series in total were performed as outlined in the joint test plan, with deviations mentioned
in the report. Each test series provided information on specified performance parameters, as shown
in Table 1. One test series was performed on wastewater to provide performance information on
wastewater toxicity.

Quality Assurance
DHI provided internal review of documents and an audit of test performance. Battelle and ETV
Canada ensured that the verification and tests were planned and conducted to satisfy the
requirements of U.S. ETV and ETV Canada, including input and concurrence from their
stakeholder groups. Battelle, U.S. EPA, and ETV Canada quality assurance staff conducted a data
quality audit of at least 10% of the test data. Battelle conducted an on-site technical systems audit.
Three technical experts provided an independent review of the test plan, and four technical experts
reviewed the verification report. This statement reflects the verification results after performing the
above quality assurance actions.
TECHNOLOGY AND PRODUCT DESCRIPTION
The following description of the LUMIStox
luminometer is based on information
provided by the vendor and does not
represent verified information.
The LUMIStox 300 is a bench top
luminometer that has been developed as a
measuring unit for the luminescent bacteria
test. In combination with the LUMIStherm incubation block it conforms to the technical
requirements of ISO 11348-1, 2 and 3.
Page 3 of 6
-------
The LUMIStox 300 has a built-in photometer function and an automatic measuring and evaluation
routine, which enables it to recognize color effects in the luminescent bacteria test and to take these
into account in the test results.
The LUMIStox 300 can be connected to a PC running LUMISsoft4 that enables the operator
performing and recording luminescent bacteria tests to conduct ISO 11348-1, 2 and 3 requirements.
The results from LUMIStox are either LID or ECso-values, representing Lowest Ineffective Dilution
(LID) causing less than 20%l inhibition and Effective Concentration (EC) causing 50% inhibition,
respectively. The ECso values are a commonly used result from toxicity tests, while the LID is used
in Germany. In this verification, results have been obtained for ECso values or directly as
percentage of inhibition.
VERIFICATION RESULTS
Table 3 Description of matrix and effect for LUMIStox.
Matrix
Effect
LUMIStox is applied for wastewater; river and lake
water; leachate from soils and waste; or directly in
effluent chemicals. Verification testing was
conducted on domestic and industrial wastewater
effluents.
Measurement of toxicity as indicated by inhibition
of luminescent bacteria by a variety of compounds
including metal ions, organic pesticides, inorganic
and organic pollutants and surfactants.
Additional parameters included:
User manual quality, product cost, environmental
health and safety.
Performance Parameters
The performance parameters listed in Table 4 are results for ECso values or percent inhibition
generated after 30 minutes. Only 30-minute results are included here since they represent the
standard length of time for reporting ECso results.

1)For colored samples, robustness results are presented after the use of color correction. For the BaSO4-turbid samples, robustness
results are presented without the_use of color correction. For domestic wastewater, adjustment was made to account for the negative
inhibition from the wastewater; if color correction was used the robustness was -20% to 70%. The values listed in table are the best
achievable robustness.
LID of 20% inhibition is stated in ISO 11348-3, Annex B, Section B.5.

General observations included the following.
• The user manual and other instructions were found to be complete.
• The results showed that the use of color correction is essential when testing colored samples,
while the results for turbid BaSC>4 samples showed that the color correction function is not
applicable. The applicability of color correction for other types of turbid samples was not tested.
• No additional risks for occupational health and environment were noted compared to
conventional effluent wastewater testing or analysis.
• The purchase price for the LUMIStox, LUMIStherm and LUMISoft4 software at the time of
testing was 13,000 Euro (17,800 $U.S.). Additional equipment such as cuvettes, bacteria and
chemicals on a cost-per-sample basis as used for testing for ECso according to the ISO 11348-3
was 18 Euro (23 $U.S.).
• The product costs for one laboratory day are listed in Table 5. Shelf life of the dried bacteria is
one year, and the lifetime of the rehydrated bacteria is four hours, making it possible to perform
an ECso test according to the ISO 11348-3 on three samples plus associated controls and
standards.
