New ASTM standard ensures reliable HPC testing


New automated single shot mercury analyser


The new Milestone DMA-1 evo Direct Mercury Analyser from Analytix overcomes common sampling and calibration problems. The calibration can last up to six months and is matrix independent. Samples require no sample preparation and are simply weighted into either quartz or metal sample boats that are automatically loaded into the instrument. Measurements take as little as six minutes and total mercury results are generated at the end of analysis.


Given the ease of use and cost effectiveness, the system is also ideal for use out in the fi eld or off- shore on oil platforms. Systems can be calibrated in the lab/on-shore prior to shipment, also meaning that hazardous mercury does not need to be shipped with the system. Maintenance is simple, with support often performed remotely, ideal when up-time is crucial.

IDEXX, the global expert in water microbiology, has announced that its EasyDisc®


PCA, YEA


and R2A tests, for the for the detection of heterotrophic plate counts (HPC) in water, have been published by ASTM International as the ‘ASTM D8516-23: Standard Test Method for Quantifi cation of Culturable Waterborne Bacteria Using a Defi ned Culture Medium Coated Plate’. ASTM International is an international organisation that develops and publishes standards applicable to a wide variety of industries. There are over 12,500 global ASTM standards, developed and reviewed by over 30,000 technical experts from more than 140 participating countries.


IDEXX launched EasyDisc in 2021, which is a simple solution for HPC testing, needing no agar preparation, and requiring less than one minute of hands-on time to process a sample. Post-incubation, blue colonies reduce the ambiguity of results, and colony counting is made easier by the integrated gridlines in the EasyDisc plate. With a 12-month shelf life, EasyDisc reduces the need for repetitive quality control checks and ensures that tests are ready when needed.


EasyDisc formulations cover all categories of HPC testing: PCA and YEA, which correlate with the pour plate method using plate count agar and yeast extract agar respectively, for the testing of drinking and source water; and R2A that is comparable to the pour plate method using Reasoner’s 2 agar for the testing of medical and/or pharmaceutical waters. In 2022, IDEXX expanded the EasyDisc platform with the DEV test, designed to correlate with the German Drinking Water Directive (TrinkwV), §15(1c).


This publication as a standard follows EasyDisc YEA test being validated and certifi ed by the French standards organisation, AFNOR, with ‘NF Validation’ for the enumeration of cultural micro-organisms in water for human consumption (drinking water) under reference IDX 33/09-03/22.


EasyDisc complements other innovative water testing methods from IDEXX, which include liquid culture methods for the rapid enumeration of E. coli and coliform bacteria, as well as detection methods for enterococci, Pseudomonas aeruginosa and Legionella pneumophila. More recently, IDEXX has introduced Tecta® microbiology testing.

The management of fl ood defence networks is being revolutionised through a combination of MRC remote cameras and AI (Artifi cial Intelligence) systems developed by Meteor Communications. This new advanced technology is already providing Water Utilities, UK Government Agencies and Local Authorities with early warning of issues within their networks, enabling targeted, appropriate responses to events as they emerge.

With 1000’s of cameras in service monitoring a wide variety of network assets such as trash screens, CSO’s, overspill channels and EDM monitors, Meteor already has operational networks of cameras providing robust, reliable, real-time image feeds from remote assets. Stakeholders such as control rooms, operators and fl ood defence teams utilise the MeteorCloud® secure web portal to view images, remotely request new images and receive alerts for potential issues.

Over the past 3 years Meteor has been leveraging the MRC camera and Meteor Data Cloud capabilities to develop Deep Learning Neural Network technologies to identify network issues, caused by issues such as blockages, high water levels or other unforeseen factors.


Taking the example of trash screens, Meteor AI has been site tested in all seasons, and found to be over 94% effective at identifying potential screen blockages and issuing automated alerts. This enhanced capability will allow users such as the Environment Agency to target resources to sites with potential issues at an early stage, and thereby enable operational effi ciencies. The severity of fl ood events will also be reduced because users will be able to proactively respond to issues more quickly, rather than to fl ood events caused by blockages in drain networks.


During the recent storm Ciarán the Meteor Data Centre (MDC) processed over 500,000 real-time images over a 3-day period with peak MeteorCloud user sessions of nearly 5x usual levels. This presented an excellent real life test of the type of events for which the MDC was designed, and proved the robust, scalable nature of the platform.


With the effects of climate change and more adverse weather conditions Meteor Communications is developing the technologies required to effectively monitor and react to situations as they arise. This enables effi cient use of resources and saves carbon through a reduction of unnecessary site visits.
