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.

Bethpage Water District officials recently filed a federal lawsuit against Northrop Grumman Corp., claiming the company’s facilities caused “irreparable harm” by creating a toxic plume that has contaminated the groundwater, costing the district millions of dollars and threatening more than 33,000 customers in Bethpage, Old Bethpage, Farmingdale, Levittown and Plainview.
According to the lawsuit, the district is demanding a jury trial to determine whether Grumman owes compensation for the costs of monitoring contaminants, operations, maintenance, treatment upgrades, and equipment required to comply with state and federal safe drinking water law; or whether Grumman would bear the expense of securing an alternative source of clean drinking water.

For most, the Thanksgiving holiday is a time to gather with family and feast on a smorgasbord of traditional holiday cuisine.
But for six Farmingdale High School Seniors, it means helping others have a full meal.

The Farmingdale Dalers took on the Sachem North Flaming Arrows last Saturday afternoon at Stony Brook’s LaValle Stadium for the Long Island Conference I Championship in front of 7,200 fans. This was the Dalers second trip to the finals since losing to Floyd last year. The Dalers went into the game looking to finish a perfect season.

The Farmingdale Dalers, ranked first in the division (11-0), came out to defend their title as Nassau County champions against the no. 3 seed, the Massapequa Chiefs (8-3), who attempted to take it away. The Chiefs, after losing to the Dalers 33-8 in week 4, would of liked nothing better then to defeat the Dalers in front of 4,000 people at Hofstra and grab the title. The rivalry was all the talk this week and the Nassau County Police had extra Officers all around the stadium at Hofstra.
