Using our patented satellite imaging technology to detect the presence, location, and concentration (in parts per billion) of early Cyanobacteria and Chlorophyll-a blooms in the world’s lakes, streams, rivers, ponds, and reservoirs, our data saves money and can save lives. Our reports are derived from pinpoint precision GIS-based data. Early detection can help curb the blooms before they grow out of control, lowering chemical treatment costs and reducing damage to the water body.
Blue Water Satellite's ability to detect levels of Phosphorus - both in water and in surface soils - will help you keep the Cyanobacteria and Chlorophyll-a blooms from ever occurring.
And we cover every square inch of the earth, eliminating the shortcomings of arbitrary random location "grab" sampling.

Still skeptical that precise, reliable, detection can be done by satellite? See how we proved it. Read our Correlation White Paper Correlation White Paper

The LakeESP is a complete monitoring buoy for long-term water quality monitoring and management. The monitoring buoy features real-time monitoring of water column temperature stratification, meteorological parameters, and water quality parameters. Meteorology sensors can include net long and short wave radiation, humidity, air temperature, wind speed/ direction, barometric pressure and liquid precipitation. Meteorology sensors are positioned on the lake buoy above the water surface. Water column sensors are attached to the lake buoy below the water surface and can include temperature, dissolved oxygen, pressure, and PAR (Photosynthetically Active Radiation). The LakeESP monitoring buoy can transmit data via GSM cell phone or other methods to a user specified destination. Measurements are typically collected once per minute, but can be collected as often as once every few seconds, depending upon customer specification.

The LakeESP monitoring buoy is a stationary floating system that can be easily installed and is moored to compensate for fluctuating water levels.

How does Phoslock work within a water body?

Phoslock granules are generally mixed with in situ water and applied to a water body as a slurry.  As the slurry settles, phosphate anions in the water column are bound to the lanthanum cations contained within the bentonite clay.  Once Phoslock has settled on the sediment water interface, it forms a thin layer, usually less than 1 mm in thickness. As long as sufficient binding sites remain on the clay, this layer continues to remove any phosphorus that would normally be released from the sediment into the water column when anoxic conditions develop.

Once phosphorus is bound to Phoslock, it is no longer bioavailable for use by algae for assimilation and growth.  This lack of nutrients in the water body has a direct impact on the ability of algae to proliferate.

Phoslock operates over a wide pH range (4-11) and binds phosphate even under anoxic conditions.
