Algae in Drinking Water a Concern
Some water-treatment plant operators along western Lake Erie, where harmful algae blooms are a threat to the drinking water, think there should be state or federal guidelines for detecting the algae inside their plants.

The city of Toledo estimated it spent an extra $1 million last year to combat the toxins. The city even barred residents from using the water because of toxins from algae in the lake.

The algae growth is fed by phosphorus from farm fertilizer runoff and other sources, leaving behind toxins that can kill animals and sicken humans. Without any guidelines on how to remove the toxins, plant operators have come up with their own strategies.

They’ve found that the best option, powdered activated carbon, is also very expensive. Toledo officials anticipated spending $3 million last year to treat its water, but the cost increased to $4 million because it needed more chemicals to treat the toxins.

Chesapeake Bay Underwater Grasses Continue to Rebound - Underwater grasses continue to rebound across the Chesapeake Bay, Maryland and Virginia scientists reported Thursday, with aerial surveys showing a 27 percent expansion last year.
