AlgaeTorch tested in Cape Town

Measuring algal chlorophyll at Rietvlei

Yesterday saw the testing of the bbe-AlgaeTorch at 8 locations in and around Cape Town.  The instrument performed to specification and produced excellent results from replicate samples at each site (see Table).  Moreover, it was possible to test 8 locations within three hours!  The testing was able to show the presence and contribution of cyanobacteria in lakes such as Zeekoevlei, Princess Vlei and Rietvlei, as well as measure the very low or zero levels in the clean (low nutrient or plant-stabilized) systems such as Little Princess Vlei.
