MIAMI (CBSMiami) – The South Florida Water Management District is increasing its tracking of toxic blue-green algae.

That means the agency will take additional samples from more places.

They will also be doing this at a greater frequency.

In fact, the agency has increased the number of water sampling sites by about 100, to nearly 250.

The new $2,000,000 program could double the amount of testing in some areas.

Researchers say they’ll test for more chemicals in fertilizer runoff, which is believed to help the toxic algae bloom.
