WATER QUALITY SURVEILLANCE
TAKE CONTROL OF YOUR NETWORK
WITH ATP 2G!
Tracking the microbiological quality of networks represents a true health and environmental challenge for the public authorities and private companies tasked with providing water for human consumption (also called city water, tap water or potable water).
Engaging in continuous rapid analysis of the entire system, particularly critical points, helps prevent technical failures and health risks.
Rapid microbiological analysis with ATP 2G cannot replace obligatory analyses (which are required for establishing the safety of bottled water or tap water), but represents a first-line alert tool that is low cost, easy to implement and allows the user to identify shifts in the microbial population of a network in real time.
The total biological burden measured by ATP 2G serves as an overall quality indicator. Exceeding a certain value (predefined critical threshold) could indicate:
• a presumed health risk due to the presence of pathogenic micro-organisms (Legionella pneumophila, Pseudomonas aeruginosa, Cryptosporidium parvum, Giardia lamblia, etc.);
• fecal contamination by intestinal micro-organisms linked to pollution of the source or accidental infiltration (Escherichia coli, total coliform bacteria, enterococci);
• an unusual bacterial proliferation or algal bloom due to organic pollution, seasonal/climactic variation or failure of disinfection treatments;
• establishment of biofilms or aggregates by native heterotrophic bacteria (Pseudomonas sp., Aeromonas sp., Flavobacterium sp. etc.) and some filamentous cyanobacteria on the walls of the pipes in the network or on the purifying filters used in water treatment.
The QGA™ rapid microbiological analysis kit is recommended by aqua-tools I&E for:
• Measuring the total biomass of surface or ground water, treated or stored water, etc., notably water sources whose biological content is likely to undergo significant seasonal variation;
• Continuous monitoring of the microbiological quality of a water network, especially mixed networks with many different collection sources;
• Optimizing cleaning-disinfection processes or cleaning the lines (purging) in order to reduce the amount of oxidizing biocides (chlorine, chloramines, ozone) used or the length of the process;
• Guiding biodegradation processes in the treatment of reclaimed water (controlling blockages or the activity of biofilters).
• Bottled water: continuous surveillance of the source and the linked facilities.
• Technical water (laboratory applications): ultrapure water, pure water, deionized water, demineralized water, water for hospital applications, etc.
• Technical materials: evaluation of the stimulation of microbial growth on materials designed to be in constant contact with water (standard NF EN 16421).
