Brain-eating amoeba in Louisiana’s water

Naegleria fowleri  (also known as the “brain-eating amoeba”) is a free-living, thermophilic excavate form of protist typically found in warm bodies of fresh water, such as ponds, lakes, rivers, and hot springs. It is also found in soil, near warm-water discharges of industrial plants, and in poorly chlorinated, or unchlorinated swimming pools….

N. fowleri can invade and attack the human nervous system and brain, causing primary amoebic meningoencephalitis (PAM). Although this occurs rarely, such an infection nearly always results in the death of the victim.  The case fatality rate is greater than 95%. [Source: http://en.wikipedia.org/wiki/Naegleria_fowleri]

This parish is like so many other towns we all live in…  Except that in southern Louisiana in September the weather is wicked hot and humid – and there is lots of industry responsible for creating fence-line communities.

(“Fence-line” refers to communities with refineries, gas compression stations and other kinds of industrial operations. These plants put up high wire mesh fences to keep people out of their premises, but those fences don’t stop toxins from entering the air and water of those communities. The term is used by agencies trying to address the resulting health issues occurring due to such toxins.)

The parish government has implemented “chlorine burns” to disinfect the Lions system, which serves over 12,000 people. The School Board has declared an emergency, taking school water fountains offline and putting water coolers in place. The deadly amoeba infiltrates via water vapor in the nose, and spreads to the brain causing severe damage. Residents are getting home water tests and taking precautions when swimming or bathing. Town meetings have drawn large crowds to discuss what can be done in their communities.

Grass is #1 US crop and is very water-dependent

July 14, 2014

Using satellite imagery, NASA’s Christina Milesi has been studying the impact of lawns on America’s fresh water resources. Research indicates there’s at least 3 times more surface area of lawns in the U.S. than irrigated corn, making it the largest irrigated crop.

How do lawns hurt the environment?

 fertilizers run off into drains, contaminating drinking water

 fertilizers pollute rivers and streams and damage ecosystems

 watering lawns depletes our freshwater reserves

chemical herbicides / pesticides are health risks to humans and wildlife

lawns infringe on viable habitat for pollinators like bees

 an hour of gas-powered lawn mowing produces as much pollution as four hours of driving a car

Consider Xeriscaping!

We’re all connected downstream

WHAT YOU CAN DO to protect our water resources:
Support the EPA and US Army Corps of Engineers –

It’s critical we all have clean fresh water! The EPA and USACE are proposing a clarification of their rules that protect our water quality by addressing upstream impacts on downstream communities. Ending loopholes in the 1970’s Clean Water Act will stop the free dumping of toxins into small streams and wetlands. This will affect some farmers’ use of pesticides and herbicides; but it will encourage restoration of riverine corridors and wetlands that filter such toxins. In the long-run, a tighter Clean Water Act will benefit us all.

NWNL asks everyone to jump in here!!

— Read the proposal.
— Listen to EPA Administrator Gina McCarthy on this ruling.
Contact the EPA during its 90-day Comment Period.
