Rapid Testing Kits for Cyano-toxins in Freshwater

Background Monitoring

The Abraxis test kits present a major advancement in onsite testing, but the tests do not negate the need for routine monitoring of a lake or water supply. Recording the water temperature, pH and dissolved oxygen levels with simple digital probes often gives valuable warnings of sudden changes in a lake that could proceed an algae bloom.

Proficiency CPD

The company is able to offer proficiency training on the test strips for groups of users. These training days will be support by Abraxis. Please contact us by email.

The Environmental Agency have a range of literature and fact sheets on recognising algae blooms. Key staff and temporary staff managing water should be routinely made aware of these guides.

It is very easy to forget what the lake looked like last week, but having photographs and taking images from key points of the lake shore is a good way to keep a visual diary. If you have a pier or pontoon on the lake, then taking images looking into the water is a great record.

If you have a clear plastic container, why not take a water sample, hold some white paper behind the bottle, and take a photograph with your smartphone. Include this in your weekly photo library and note any changes in colour or invertebrates (bugs) swimming in the water.

Recording the water temperature, pH and dissolved oxygen is often a good first step in collected basic parameters on the health of the water. If the temperature starts to climb above 21 degrees C, then you need to be more vigilant. If the pH starts to swing down to 9-10, then again be more vigilant. Finally, if dissolved oxygen in the day time starts to be above 120%, then there is likely to be lots of algae producing oxygen in the lake. For further advice, please contact us directly.

There are a range of optical water quality probes that record the density of blue-green algae cells in the water. These advance sensors, which are expensive, are often deployed in high risk sites, where daily or hourly monitoring is essential to protect water users. These sites often have a history of blue-green algae blooms. For further advice, please contact us directly.

If you require minute or hourly data on the basic chemistry and blue-green algae cell density in a lake or freshwater location, because the site is high risk, then onsite data loggers and telemetric warning systems are strongly advisable. These robots, can clean the water probes and send email or text alarms if these quality of the water degrades. For further advice contact us directly.

The Environment Agency have a range of on-line resources on the state of bathing waters. Some sites have pollution risk forecasts. This is an additional resource for users and operators of lake sites.
