Blue Green Wake Up Call for Toledo- and other water drinkers!

In Ohio on Saturday
August 2 a state of emergency was declared as polluted water hit the
water faucets along the west end of Lake Erie. More than 500,000 people in Toledo and its surrounding
areas depend on Lake Erie drinking water. They were advised not to
drink boil or wash their food in their tap water after a summer blue
green bloom sent concentrations of a potent liver toxin called
microcystin above EPA limits.
A U. S. Senator from
Ohio called it a “wake up call”. This water advisory was not
from a chemical plant tank leak, a broken tar sands pipeline, or a
gas well, or a coal fly ash dump. It was a more insidious source of
pollution but one we know how to fix and can do so. If we have the
will to fix it.
Blue green algae ( aka
cyanobacteria) thrive on phosphate rich fertilizer from sewage and
manure large amounts of which can run off during heavy rains from
farm fields. Lots of rain plus lots of fall and winter spreading of
sprayed on liquid manure from big factory farms that isn't worked
into the soil for rapid uptake by growing plants create prime
conditions for these events. Lake Erie, a drinking water source for
11 million people has suffered a number of huge blue green blooms in
recent years. Closer to home a couple weeks ago I saw a small blue
green bloom at the south end of Fair Haven Bay and also at about the
same time during a hot calm spell I noticed a possible small bloom
in shallow water on the neighborhood open lake beach a few yards from
the mouth of a little creek.
Toledo residents stripped
the supermarkets of bottled water in short order as the city
scrambled to pipe in supplies from other sources. Businesses that
risked exposing workers or customers to tap water closed.
Restaurants, public institutions like libraries, schools, parks, and
universities all closed. Anyone who thinks it is too expensive to
regulate the application of farm fertilizers should consider the
costs and lost revenues of a water advisory. Last year Toledo spent
an additional million dollars on water treatment. This year one
suspects they'll be spending a bit more. And we aren't even
considering health costs, vet bills for sick pets, impaired
waterfront property values or other possible costs- just the
immediate expenses that this bloom imposed on the city and its
residents.
There is a lesson here
folks. Mother Nature always bats last. And if you don't play by her
rules, you will pay.
