The solution
Continuous E. coli estimation
Beach Pulse continuously estimates E. coli concentrations in bathing water across the range that matters for bathing water management. Instead of waiting for the next scheduled sample, you get an ongoing picture of how water quality develops. We are also working on estimating intestinal enterococci.
How it works
Multiple calibrated water-quality sensors collect data from the bathing site. Beach Pulse combines those measurements with environmental and standard weather data. Our algorithm estimates E. coli levels and flags significant changes.
From measurement to estimated level
- 01Water measurements
Calibrated sensors at the bathing site.
- 02Environmental data
Local conditions that shape the water.
- 03Weather data
Standard weather such as rainfall and temperature.
- 04Beach Pulse algorithm
Combines the inputs into one estimate.
- 05Estimated E. coli level
Decision support between laboratory samples.
How the sonde measures
The sonde hangs under the jetty, well below the surface and out of the way of swimmers. It continuously collects water measurements that the Beach Pulse algorithm turns into an estimated E. coli level between lab samples. This is not a laboratory analysis. It is continuous decision support, calibrated against accredited labs.
- Reading from the sonde
- Impact in the water
- Signal back
- Status in the app
What we measure and what it reveals
The sonde logs several parameters at once and the algorithm reads them together. The combination is what makes a change interpretable, not any single value.
What the sonde measures
- Water temperatureDegrees Celsius
- TurbidityCloudiness in NTU
- pHAcidity
- Dissolved oxygenMilligrams per litre
- ConductivityConductance and dissolved salts
What we can detect
- E. coliContinuous estimate between lab samples
- Intestinal enterococciIn development: estimate between lab samples
- Sewage impactDischarge and overflow reaching the beach
- Bathing water qualityFour classes based on the applicable limits
- Impact after rainRunoff that clouds the water
- Water chemistry anomaliesOxygen depletion and pH outside range
- Operating statusWhether the sonde is in the water and reading correctly
From measurement to decision
When Beach Pulse indicates elevated or changing E. coli levels, laboratory samples can be targeted to verify the result.
We do not replace laboratory samples. We make them targeted.
Better monitoring can also cost less
Continuous information can reduce the need for routine laboratory samples while giving a much more detailed picture of bathing water quality.
The objective is simple: improve monitoring while reducing its total cost.
Proven where it matters: in the water
Beach Pulse is not a laboratory concept. The technology has been deployed and validated in live bathing waters under real conditions. That real-world validation is a central difference.
At a glance
Beach Pulse does not replace legally required or certified laboratory analysis. Continuous estimation makes laboratory samples more targeted and can reduce total monitoring cost.
