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 …

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 …

Dams and Demand for Sand Threaten World Beaches

Documentary filmmaker Denis Delestrac has recently completed the movie Sand Wars, which looks at the intense demand for what may seem like an abundant natural resource. In some cases worldwide, the sand business has taken on a dangerous criminal dimension. In a TedxBarcelona Talk called Let’s talk about sand, Delestrac introduces the complex subject of beach sand, including erosion and exploitation, with style and charisma. There are also some good …

On Site Wastewater Disposal Systems: Soil Considerations

According to the U.S. Census Bureau, as of 1990 there were 24.67 million residences serviced by on-site waste disposal (OSWD) systems, representing 24.1 percent of the total number of households. The highest concentration of OSWD systems is found in the New England states where Maine, New Hampshire, and Vermont have about 50% of their households using them. That number has surely grown, but, unfortunately, 1990 data is the most up-to-date …

Is Fukushima Out of Control?

Following up on a recent post, the news out of Fukushima just got worse last week in what appears to be shaping up as a major environmental crisis requiring a massive and coordinated international response. A spike in radioactivity led to the acknowledgement by Tokyo Electric Power Company (Tepco) of a leaking tank used to store some of the more heavily contaminated water from the damaged reactor. Japan’s Nuclear Regulatory …

Groundwater Whack-a-Mole

In two high-profile cases, efforts to block the flow of contaminated groundwater resulted in short-term relief – until water tables rose and leaks started popping up all over the place. It’s groundwater whack-a-mole. Red and Bonita Mines Near Silverton, CO, owners of a metallic mine with an acid mine drainage problem and state regulators reached a consent decree that was supposedly going to solve the problem. A tunnel access to the …

The Ins and Outs of Fracking and Underground Waste Injection Wells

When the Akron Beacon-Journal Online publishes its updated interactive map of active, permitted, and producing oil and gas wells in Ohio, it places another map right below it. The second map shows underground waste injection wells. These two maps belong together because underground injection wells are used to dispose of the polluted flowback water from high volume hydraulic fracturing (fracking) operations. When thinking about potential for groundwater contamination, hydrofractured oil/gas …

Soil Anisotropy: Mechanisms and Hydrologic Consequences

Introduction Anisotropy, which is the opposite of “isotropy,” is a term used to denote preferential flow direction in soils and other geologic materials. If soil consisted of perfectly spherical grains, flow rates would be isotropic – the same in all directions, other factors being equal. Soil doesn’t consist of perfectly spherical grains, however. It’s commonly understood that flow of air and water through soils is greatly influenced by grain size, …

EPA to Enbridge: Dredge More Submerged Oil from the Kalamazoo River

On July 25 2010, the 30-inch diameter Enbridge 6B pipeline ruptured near Marshall, Michigan. Roughly 1 million gallons of diluted bitumen (DilBit) from Canadian oil sands spilled into Talmadge Creek, a tributary to the Kalamazoo River. Nearly three years later, the cleanup continues. Last week, the U.S. EPA issued a final Administrative Order requiring Enbridge, the owner of the pipeline, to conduct additional dredging to remove submerged oil from three portions of …
