Tests were done over a 10 month period in 2015. The river's parameters covered an area of 1,300 feet in length, 60 feet in width and 7 feet in depth. During the 10 months of testing, only our probiotics were used without construction or engineering assistance. The river's nutrient reduction results were staggering considering our limited resources.

Photos of the testing are listed below.
This was a sewage problem where raw sewage infested with high levels of phosphorus was being dumped into Johannesburg rivers.
Tests were conducted at two areas; Queens Street Bridge and Clarkson Street. The testing was held over a 30 day period from May 1st to June 1st, 2017.
During that period, only our all natural probiotics were added by dumping product from a bridge. No construction or engineering assistance was used, just our probiotics. The nutrient reduction results were astonishing.
The test results are listed below.

The E-Coli, Phosphate and Dissolved Oxygen results are displayed to the right.
May 2 (5-2) - E-Coli tested extremely high at 240000 part per million (ppm) because of the sewage in the rivers. E-Coli is a wide range of harmful bacteria that can cause various diseases.
June 1 (6-1) - E-Coli tested at 2400 ppm at both locations. An astounding reduction in just one month.
May 2 (5-2) - Phosphate levels
