algal blooms

Toxic algal blooms have been happening more often in the rivers off Lake Okeechobee. One of the main causes is phosphorous runoff from wastewater and farmland. But a new filter may make algal blooms caused by wastewater a thing of the past. 

Fertilizer Bans Take Effect Around Indian River Lagoon

Jun 2, 2016

Fertilizer bans start Wednesday in the five-county region of the Indian River Lagoon.

The bans also apply in nearly all of the region’s municipalities.

Frequent rains wash fertilizers into the lagoon, feeding the blooms that this spring triggered the worst fish kill in the lagoon in modern history.

Duane De Freese of the Indian River Lagoon National Estuary Program says the bans are aimed at nitrogen and phosphorus, nutrients at the heart of the lagoon’s problems.
