Wetlands and Flood Mitigation: The 10 Percent Solution

Wetlands and Flood Mitigation: The 10 Percent Solution

Following the Great Flood of 1993, an official report called for more research to find ways to prevent flood devastation, apparently unaware the problem had been mostly solved, conceptually over a decade earlier. But taking action through the implementation of a national wetland restoration program has faced intractable political and economic obstacles.

Keep Your Shirt On, Save Some Coral?

Keep Your Shirt On, Save Some Coral?

This is not great news, especially for those of us who like to be out in the sun but get really bad sunburns. As reported by Nature and Scientific American, Hawaii state senator Will Espero has introduced a bill to ban sunscreens containing oxybenzone and octinoxate, two chemicals that may pose risks to us, such as endocrine disruption, as well as to coral. The Environmental Working Group maintains lists of …

Rejected Export Corn Prompts Class Action Suit

Rejected Export Corn Prompts Class Action Suit

Updated 16 November 2016 When it’s assumed that food grown using modern high-tech agriculture, including GMO crops and greater reliance on chemical pesticides, is absolutely necessary to feed a growing world population, one might be tempted to question that assumption when the most populous nation in the world rejects such food. Syngenta Litigation There are some angry farmers in the U.S. who, in 2013-2014 were unable to sell their GMO …

Lake Erie Algae Blooms Correlate to June Rainfall

Lake Erie Algae Blooms Correlate to June Rainfall

June precipitation appears to be positively correlated to algae blooms in Lake Erie. Looking at monthly precipitation data readily-available from Weather Underground and comparing it to the Western Lake Erie Algae Bloom Severity Index, I was surprised by the strength of the correlation (0.6, 0.85 with an “outlier” removed). June precipitation was the only month to correlate to the Severity Index in my data set and I was surprised that …

Lake Erie Watershed Soil Phosphorus Study Shows Glyphosate Link

As reported recently by Laura Barrera in the┬ámagazine No-Till Farmer, a study led by Ohio Northern University chemistry professor Christopher Spiese links the popular herbicide glyphosate to dissolved reactive phosphorus (DRP) desorption in soils. Mobilization and runoff of phosphorus to streams and lakes is associated with toxic algae blooms in Lake Erie and the Gulf of Mexico Dead Zone. For decades, soil scientists have understood phosphorus to form low-solubility compounds …

Herbicides, Critical Source Areas, and Vegetated Buffers

Herbicides, Critical Source Areas, and Vegetated Buffers

Waging Chemical Warfare on Weeds Last fall, while on one of my country road walking routes, I noticed an advanced infestation of marestail (Conyza canadensis) in a soybean field. Evidently, this weed, and others, is becoming herbicide-resistant. A new agricultural herbicide called Acuron (link goes to manufacturer’s website) is on the market, and in some fields. Acuron has been developed in response to “superweeds” that have grown resistant to glyphosate, …

A Journey on the Dirt Road

A Journey on the Dirt Road

When I was seven years old, my family moved from Dearborn, a modern suburb of Detroit, Michigan and the home of Henry Ford, to a much smaller and older town in Northwest Ohio, called Defiance. Perhaps the most notable aspect of Defiance was that it was built at the confluence of the Maumee and Auglaize rivers and regional folklore had it that the meeting of these two rivers protected the …

Lead, Plumbosolvency, and Phosphates in the Environment

What’s happened to the water supply in Flint Michigan is especially ironic considering the state is surrounded by four of the five Great Lakes, which make up 95% of the surface fresh water in the United States. If Michiganders can’t have safe public water, who can? Plumbosolvency The problem, briefly summarized here, boils down to variable source water chemistry, plus common chemicals added at the water-works, interacting with outdated lead plumbing components …

Agricultural Runoff and Ohio’s Senate Bill 1

Agricultural Runoff and Ohio's Senate Bill 1

In response to the August 2014 shutdown of Toledo’s water supply due to microcystin contamination, the Ohio legislature passed Senate Bill 1, which regulates fertilizer and manure application to farm fields. Essentially, the new regulations prohibit spreading manure or fertilizer in the Lake Erie Watershed when soils are frozen, snow-covered or saturated, or if there is a more than 50% chance of at least one-half inch of rain in the …
