As recently as June 30, following rain the previous day, E. Coli levels increased to around 2000 CFU/100mL at Alexandra III Bridge. But E. Coli levels near Alexandra III Bridge still climbed to around 10000 CFU/100mL on the second day of rain. Longer term trends show there has been a “significant improvement” in water quality, according to Dan Angelescu, the company’s CEO. That’s more than three times higher than the level needed for “good” water quality, according to CNN’s calculation. In comparison, between June 24 and July 5, average E. Coli levels dropped to around 880 MPN/100mL, according to Fluidion.
