Dublin City Council (DCC) Central Laboratory wishes to procure a new gas chromatography mass spectrometry system for water quality analysis based on SI99 of 2023. Dublin City Council’s Central Laboratory conducts and provides INAB accredited testing of public and private drinking water supplies, as well as testing Uisce Eireann water samples from processing and the supply network as required. In future, DCC expects to focus increasingly on private supplies, and the applicable legislation requires the same range of tests as at present. Many of these tests are currently outsourced by DCC, meanwhile limits and enforcement are expected to tighten over time. The main focus of the current procurement specification is to bring analyses back in-house and onto DCC’s INAB ISO17025 scope, to maximise 1. Practicable reduction in the costs of outsourced analyses by the Central Laboratory 2. DCC’s ability to implement its current and future statutory testing 3. DCC testing capability to serve Local Authorities around Ireland 4. Provision of impartial means for DCC to verify the effectiveness of water management initiatives for Climate and Urban Resilience. Analytical parameters of interest are based on Statutory Instrument 99-2023 and include core suites of Volatile Organic Compounds (VOCs including THMs), Pesticides, and Per- and polyfluoroalkyl substances (PFAS). Potential future additions to the scope include the endocrine disruptors and (micro)plastic residues. To address this Dublin City Council request tender’s equipment supply, delivery, installation, setup, service and maintenance, warranty, software licences and upgrades, and a stock of consumable equipment parts, and training: for a Gas Chromatography system with a Triple Quadrupole Mass Spectrometer (GC-QQQ), Helium saver, and autosamplers for Purge and Trap and Solid Phase Micro Extraction.
