Microbiological analysis for Drinking Water

Startseite

  • Drinking Water Testing from the Household Installation: Mikrobiology

    100.00 CHF
    Total microbial count (Aerobic, mesophilic germs), Enterococci, Escherichia coli.
    Microbiological testing of drinking water hygiene in domestic installations (tap, shower etc)

    This analysis package provides you with a comprehensive overview of the microbiological information required for drinking water hygiene in accordance with the Swiss Drinking Water Ordinance (TBDV), as well as the total microbial load:
    The total microbial count (also known as aerobic, mesophilic microorganisms) gives insight into the general bacterial load of the water. According to the TBDV, this parameter is examined within the distribution system up to the building inlet but is also a relevant indicator for evaluating water quality within domestic installations up to the tap.
    Enterococci and Escherichia coli are indicator organisms that signal microbial contamination and must not be present in drinking water in accordance with the TBDV.
    Note: Additional chemical and physical parameters for assessing drinking water quality—such as sensory inspection for turbidity, color, and odor, as well as testing for pH, water hardness, nitrate, heavy metals like lead, or metals like copper and iron (indicative of corrosion), pesticide residues, or PFAS—can be found under “Chemical and Physical Water Quality Analysis”.
