ISO 7899-2 Enterococci Testing in Drinking Water
The ISO 7899-2 standard is a comprehensive framework designed to ensure the quality and safety of drinking water by detecting enterococci, which are bacteria that can indicate fecal contamination. This test is crucial in maintaining public health and ensuring compliance with regulatory requirements.
In this service, we employ advanced microbiological techniques tailored specifically for the ISO 7899-2 standard to identify enterococci in drinking water samples. Our method involves several critical steps: sample collection, preservation, and transport; inoculation on selective media; incubation at appropriate temperatures; colony counting; and confirmation by biochemical tests.
The significance of this test lies in its role as a sentinel for potential contamination sources. Enterococci are resilient bacteria that can survive harsh environmental conditions and are not pathogenic to humans, making them excellent indicators of sewage pollution in water supplies. By detecting these organisms, we ensure that drinking water meets the highest safety standards.
The ISO 7899-2 method is recognized for its reliability and consistency across different laboratories. It helps maintain public confidence by providing accurate data on water quality. The test results are typically reported within 5 business days, ensuring timely decision-making processes for stakeholders involved in water management.
The equipment used in this process includes sophisticated incubators, selective media such as m-CEM agar, and spectrophotometers for quantification. Our team of experts ensures that every step adheres strictly to the ISO 7899-2 protocol, minimizing any potential deviations from expected outcomes.
Our laboratory is certified according to ISO/IEC 17025:2017, ensuring that our services meet international standards for competence and capability. We also comply with other relevant regulations such as NSF P473, which governs drinking water system components intended to come into contact with potable water.
By choosing this service, you can rest assured knowing that your facility complies fully with regulatory requirements and contributes positively towards environmental sustainability goals. Our commitment to precision and thoroughness ensures that no detail is overlooked during the testing process.
