Toledo’s water crisis: Why we haven’t seen the end of it

Toledo Water Problems

Toledo, Ohio’s weekend-long drinking water scare came to an end this morning, but this Midwestern city’s water woes are far from over.

The buzz word in Toledo over the weekend was microcystin, referring to a deadly toxin found in blue-green algae blooms. Dangerous levels of the substance in Toledo’s drinking water led to a advisory against drinking, brushing teeth or bathing in city water.

While death is rare in connection with the toxin, it did cause 75 deaths in Brazil in 1995. Microcystin can also cause liver malfunction, diarrhea and vomiting.

This weekend’s scare was a result of widespread algal blooms in the Maumee Bay area of Lake Erie, Toledo’s main water source. The blooms are not, however, the result of a natural disaster; Toledo’s water crisis is the first of what will likely be many man-made water crises related to unnatural growth in Lake Erie.

The culprit

Algal blooms occur as a result of an inordinate amount of fertilizer flowing into Lake Erie from farms on the watershed.

86% of the fertilizer used on farms in Ohio, Indiana and Michigan is in the form of phosphorus-packed pellets.

The use of fertilizer isn’t necessarily dangerous on its own, but a popular agricultural practice in the Lake Erie region called no-till farming can have some stark unintended consequences.

In order to prevent erosion, farmers avoid plowing their fields, leaving fertilizer pellets on the surface, ready to be washed away. This is where nature comes in. Heavy rains easily wash away about 1 pound per acre of fertilizer into the Maumee River, which feeds into Maumee Bay.

Just as phosphorus is intended to fuel crop growth, it feeds algae in Lake Erie, leading to toxic algal blooms.

A recurring problem

Algal blooms are nothing new in Lake Erie. In the 1960s, rampant agricultural and industrial pollution – to the tune of 64 million pounds of phosphorus per year – fed algal blooms.

In addition to contaminating Toledo’s water supply, the growth led to seriously damaged marine life, a pressure point thanks to the multi-billion dollar Lake Erie tourism industry. U.S. and Canada officials teamed up and spent $8 billion on sewage plant upgrades and cut the amount of phosphates allowed in household products.

It seems obvious that this sixth straight year of increasingly widespread algal blooms necessitates some governmental intervention similar to that seen in the 70s and 80s.

Today, a financial commitment of this stature (which, we might add, would be significantly higher considering inflation) would require much more than Toledo opening her pocket book. Farmers in Ohio as well as Indiana and Michigan (who share the same watershed), would have to commit to cutting fertilizer use or finding an alternative to no-till farming that would also not contribute to erosion. This is a highly unlikely outcome unless officials agree to compensate the farmers who will have to make significant changes to their practices.

In fewer words, don’t expect a solution any time soon.

This is not the end

Lake Erie’s science-fiction-style neon green takeover this past weekend is unfortunately going to be a familiar scene in lakes across the globe. A 2012 report suggested that algal blooms will be “one of the most serious health risks of the 21st century,” appearing in China, Japan, Brazil and Australia. In the US alone, more than 40,000 large lakes may contain microcystin.

With the rising importance of providing food for a booming population and an extreme water shortage hitting America’s largest agriculture-producing state, we can only expect use of phosphorus-laden fertilizers to continue.

Rising temperatures have lead to more frequent and volatile storms, carrying an increasing amount of phosphorus into water sources. Toxic algae blooms thrive in higher temperatures.

The problem is complicated further by foreign species such as Lake Erie’s zebra mussels, which eat non-toxic competitors to blue-green algae and excrete more phosphorus for the toxic algae to feast on.

Lesson learned

The recurring theme every time a water crisis arises as a result of preventable human actions is that it is the citizen’s responsibility to care for his or her own water.

While a municipality’s first interest should always be its own people, we see time and again that political complications often take the front seat. This current crisis will likely be relegated to the back burner until elections have passed.

In the mean time, we recommend writing your local representative and ask about what your municipality is doing to avoid the oncoming dangers of algal blooms. Also, consider a drinking water system to protect yourself and your family from future water crises.

 

Algae Invade Southern California Drinking Water

myFOXla.comResidents  in a number of inland areas are dealing with some seriously stinky water, the result of a summer algae bloom in a state reservoir.

Silverwood Lake, the highest elevation reservoir in the state water project  is suffering from an abundance of blue-green algae caused by warmer temperatures, possibly the result of global climate change.

The algae makes the water from the reservoir smell and taste musty during the heat of summer, according to the Metropolitan Water District.

Affected areas include Claremont, La Verne, Walnut, Diamond Bar, Rowland Heights, Upland, Chino, Chino Hills, Rancho Cucamonga, Fontana, Riverside,  Corona, Norco, Eastvale, Jurupa Valley, Lake Elsinore, Hemet, Perris, Murrieta and Temecula. 

The MWD says there is no health risk from drinking the water, although it may be somewhat unpleasant.

The Department of Water Resources is planning to spot treat the reservoir this Thursday and Friday with a form of hydrogen peroxide which will neutralize the overgrowth.  

While the water is safe to drink, some water agencies are recommending refrigerating the water to get rid of some of the nasty smell and taste.

What Are the Effects of Algae In Your Water?

Blue-green algae, otherwise known as cyanobacteria or “pond scum,” are microscopic organisms that thrive in pools of standing water when exposed to sunlight during the warmer months of the year. Although they are not typically seen in homes, they are common in ponds and other standing bodies of water. Unfortunately in this case, they have thrived in the reservoir from which we get our drinking water. 

 

Visible Effects

  • Algae can cause drinking water to change color, but in most cases it is undetectable. Only in extreme situations will the blue-green or yellowish-brown tint of an algae infestation become visible in faucet water. Algae-infested water may also produce scum.

Smell Test

  • Algae in drinking water don’t give off an odor until the problem is quite severe. In such situations, according to the government of New Brunswick, it will smell like freshly cut grass; in extreme cases, it will cause drinking water to smell like sewage or garbage.

Health Effects

  • While not all algae produce toxins, it is not easy to tell the nontoxic type from the more dangerous algae. Toxic chemicals released by algae can lead to a number of health problems. If too much is ingested, it can kill animals. According to the Florida Department of Environmental Protection, humans who drink water poisoned by algae toxins can experience a litany of health issues. This includes long-term problems with the liver, digestive and nervous systems, including liver cancer. Other issues that can come up include headaches, sore throat, fever, vomiting and diarrhea. Contact with the algae toxins on the skin can lead to hives and rashes.
