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?

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 …

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 …

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, …

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here, boils down to variable source water chemistry, plus common chemicals added at the water-works, interacting with outdated lead plumbing components …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

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 …

Field Drain Tile and the “Re-Eutrophication” of Lake Erie

Algae Blooms, Microcystin and Phosphorus It’s been over a year since Toledo, Ohio and surrounding communities shut down public water supplies due to an algae bloom and microcystin contamination in western Lake Erie. Was the trouble a “one-off” or can we expect more of these events in the future? While attending a seminar this year hosted by the Michigan Chapter of the Soil and Water Conservation Society, my interest was …

Update: American Farm Bureau Federation et al. v. EPA Oral Arguments

American Farm Bureau Federation, et al. v. EPA, Case 13-4079 oral arguments were held Tuesday (see previous post) and early indications suggest the Farm Bureau is fighting an uphill battle as it attempts to block the EPA from implementing a Total Maximum Daily Load (TMDL) program for Chesepeake Bay. The program calls for a 25% percent cut in nitrogen, 24% cut in phosphorus, and 20% reduction in sediment loads by …

American Farm Bureau Federation vs. EPA: Oral Arguments Scheduled for Tuesday

American Farm Bureau Federation, et al. v. EPA, Case 13-4079 oral arguments are scheduled for Tuesday, November 18, 2014 at U.S. Court of Appeals for the Third Circuit in Philadelphia. The American Farm Bureau Federation (Farm Bureau) is suing the Environmental Protection Agency over its authority to regulate farm runoff. The issue has gained attention following this summer’s “do not drink” advisory affecting over 500,000 residents in the Toledo, Ohio …

Remembering the 1966 Riga Confined Space Tragedy

On a Saturday afternoon in May 1966, five men lost their lives, wives lost their husbands, and twenty children lost their fathers. Consider it a cautionary tale about the lethal danger of hydrogen sulfide. The confined space was a cistern fed by a 300-foot deep water well and the gas apparently occurred naturally in the ground. The accident was reported as far away as Sidney, Australia via Associated Press wire …
