State of Emergency Declared in Florida
to Combat Harmful Algal Blooms
On July 9, 2018, Florida Governor Rick
Scott issued an emergency order in seven
Florida counties including Glades, Hendry,
Lee, Martin, Okeechobee, Palm Beach and
St. Lucie counties in efforts to address the
impacts of harmful algal blooms caused by
water discharges from lake Okeechobee.
EPA Researchers Develop Strategies and Methods to Help
Predict Harmful Algal Blooms in Kansas
At Milford Lake—which discharges into the Kansas River, a drinking water
source for more than 800,000 people, EPA researchers are working with the
state of Kansas and other partners to develop monitoring tools for predicting
harmful algal bloom events, as well as understanding how toxic blooms form
to minimize future blooms.
Ohio Takes Steps to Confront Toxic Algae Crisis
On July 11, 2018, the state of Ohio took two steps to reduce farm runoff
pollution into Lake Erie, the No. 1 cause of toxic algal blooms. The actions
include an executive order requiring farmers to craft and implement plans to
reduce run-off pollution that runs into the Maumee River that feeds into Lake
Erie, and a bill, S.B. 299. investing $36 million to help farmers prevent manure
and excess fertilizers from running off farm fields and polluting waterways, by
paying for farming practices such as soil testing, injecting nutrients into the
soil (rather than on the surface), planting vegetation around fields to absorb
nutrients, and installing natural drainage systems to keep water on fields.
