I read with interest about the panel discussion on the pros and cons of so-called “hydrofracking.” The debate as framed makes good points, however, it also misses a few key points.
When I was an exploration and development geologist for a Fortune 100 oil and gas company, for all the majors I worked with the preferred industry standard practice for both oil and gas well completions was called an “acid frac,” or an “acid job.” Based on my understanding, this is still the preferred method for non-horizontal wells, not hydrofracking.
The acids pumped into these wells, such as hydrofluoric and hydrochloric acid, are highly concentrated to “clean out” or dissolve rock and natural cements to produce preferential flow paths for oil and gas. These old practices involve hundreds of thousands of U.S. wells—more than are typically hydrofracked. These practices are unregulated, as are the drilling muds.
“Mud” is a misleading term. These muds are laden with polymers, chemicals, and heavy metals formulated to bring to the surface crushed rock, coat the borehole, and prevent blowouts. My company experienced a “blowout” in Oklahoma that blew the entire drill string out of the hole when it encountered an over-pressured gas zone and the mud was not thick enough to counter the massive pressure. Muds are excluded from reporting, regulation or oversight.
The key to a successful well is the completion method: the type of mud used and how the well casing is cemented into place. The blow-out of BP’s Deep Water Horizon Anaconda well in the Gulf is a recent case of questionable cementing practices. There was also a major blowout several years prior in Ohio.
Well-drilling and completions are not regulated, left up to what is termed “best professional practice.” Yet large areas and groundwater zones in many old producing areas in the U.S. are contaminated from prior practices. This calls for a broad-based effort by citizens and government to reduce deaths and injuries. Despite best practices, accidents do happen.

There was a time when people knew what they were eating. Frozen meals, fast food chains and ingredients impossible to pronounce were non-existent. Instead, simple ingredients and meals were all made from scratch.
Joann P. Magri, owner of The Divine Olive, is keeping this way of eating alive. Offering hungry customers with a choice in quality foods and ingredients, Magri encourages customers to make their own meals. With shelves stocked full of 18-year-old vinegars straight from Modena, Italy, to extra virgin olive oils infused with various herbs and flavors, the Divine Olive features a variety of organic and vegan products, all 100 percent natural. It even has handmade spaghetti and fresh bread, which perfectly pairs with all of their other products.

It’s a cute little ‘bug.’ What it represents, however, is anything but cute.
An unusual-looking Volkswagen is toodling around Long Island this month. Painted to resemble the Asian longhorned beetle (ALB), the VW Beetle is part of efforts by the US Department of Agriculture to eliminate the pest, which can destroy 70 percent of an area’s tree canopy, according to the agency. Initially, officials held hope for complete eradication from about 23 square miles of LI designated as infested or at risk by 2016. Instead, this “landcape-altering pest” is spreading.

It will be difficult to top the exhilaration of being crowned Nassau County Champs, but the 2014 Farmingdale Dalers will begin their defense of the title on Sept. 13 at rival Massapequa—whom they beat to claim the crown.
“The attitude is that we have to prove it again,” said Head Coach Buddy Krumenacker, who has been at the helm since 1993. “But I think we’ll be okay,” he added.
