ECLOX Handheld Luminometer with LUMIStherm Thermoblock and LUMISsoft4 Software HACH-LANGE GmbH Willstatterstrasse 11 PHONE: +49 211 5288 0 D-40549 Diisseldorf, Germany www.hach-lange.de elmar.grabert@hach-lange.de Testing and verification of a handheld 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. Page 1 of 6 ------- 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 ECLOX Handheld Luminometer took place between January and April 2010. DHI personnel, with support from the vendor, HACH-LANGE, coordinated and supervised the testing and verification procedure. The testing took place in the DHI laboratories, H0rsholm, Denmark. DHI operated the luminometer during the testing and verification procedure. HACH-LANGE provided the product (luminometer, thermal block and software), user manuals, and operating instructions for the tests. The Eclox verification test was performed simultaneously with the verification test of LUMIStox 300 Bench Top 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. However, the ECLOX with LUMIStherm Thermal block and LUMISsoft4 Software does not fulfill all ISO 11348-3 requirements. 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.

ECLOX firmware was used instead of the software. This test was not in compliance with ISO 11348-3. The operational conditions during testing are shown in Table 2.

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 ECLOX Handheld Luminometer is based on information provided by the vendor and does not represent verified information. The ECLOX is a portable instrument designed to provide data appropriate for risk assessments in the event of environmental releases, emergency situations, preventive security measures, and regulatory monitoring. The ECLOX is designed in particular to be used for the Luminescent Bacteria Toxicity Test and to be used with a Chemiluminescence Toxicity Test. Both tests will provide results in a short-term and Page 3 of 6 ------- simple manner in the field or in the laboratory. The ECLOX used in the field gives values of percent inhibition. The ECLOX can be used to deliver luminescence values by connecting the thermoblock LUMIStherm to a computer program (LUMISsoft4). This approach is used for testing and recording data according to ISO 11348-3 for calculation of the Lowest Ineffective Dilution causing less than 20% inhibition (LID) and Effective Concentration causing 50% inhibition (ECso). In this verification results have been obtained as ECso values or directly as percentage of inhibition. VERIFICATION RESULTS Table 3 Description of matrix and effect for ECLOX. Matrix Effect ECLOX 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. Table 4 ECLOX performance parameter summary.

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 101% to 130%. The values listed in table are the best achievable robustness. Page 4 of 6 ------- 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 ECLOX, LUMIStherm, theLUMISoft4 software at the time of testing was 6,500 Euro (9,600 $U.S.). Additional equipment such as cuvettes, bacteria and chemicals on a cost-per-sample basis as used for testing for ECso according to the ISO 11348-3 was 18 Euro(23$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.
