Standard Test Method for Enterococci in Water Using Enterolert
Standard Test Method for Enterococci in Water Using Enterolert
SIGNIFICANCE AND USE 5.1 This test provides an easy and reliable method for the detection of enterococci in water within 24 h. For recreational water (fresh and marine) testing is performed to insure areas are safe for swimming. Enterolert also can be used for testing bottled water, wastewater, ground water, and drinking water. SCOPE 1.1 This test method covers a simple procedure for the detection of enterococci in water and wastewater. It is based on IDEXX’s patented Defined Substrate Technology (DST).2 This product, Enterolert, utilizes a nutrient indicator that fluoresces when metabolized. It can detect these bacteria at one most probable number (MPN)/100 mL within 24 h. The presence of this microorganism in water is an indication of fecal contamination and the possible presence of enteric pathogens. 1.2 This test method can be used successfully with drinking water, source water, recreational (fresh and marine) water, wastewater, and bottled water. It is the user’s responsibility to ensure the validity of this test method for waters of untested matrices. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
ASTM D6503-24 - Standard Test Method for Enterococci in Water Using Enterolert provides a practical, standardized approach for the detection and quantification of enterococci bacteria in various water samples. Developed by ASTM International, this test method employs IDEXX’s patented Defined Substrate Technology (DST) with the Enterolert reagent, which fluoresces in the presence of enterococci. Suitable for both presence-absence and quantitative analysis, this standard ensures efficient and reliable monitoring of water quality for public safety and regulatory compliance.
ASTM D6503-24 has broad applications across multiple sectors with emphasis on protecting public health and supporting regulatory frameworks:
