Well-water testing in advance of natural gas drilling operations in parts of Luzerne County could give homeowners with wells knowledge, a baseline for future testing and a legal leg to stand on if their water becomes tainted, some experts say.

Marcellus Shale gas drilling is coming into Luzerne County this summer. EnCana Oil and Gas USA Inc., based in Denver, Colo., will be starting a site in Lake Township off Zosh Road in June or July.

Drilling could also be coming to other mostly Back Mountain area communities. Some area groups have voiced strong opposition to the drilling, and some landowners in counties where drilling is already taking place have said their water wells have been inversely affected by gas drilling activities.

EnCana Community Relations Adviser Wendy Wiedenbeck said her company has drilled 8,700 gas wells and has not had “any instance of well water becoming contaminated.” She said EnCana takes great pains not to damage water wells.

“It is in our best interests not to impact water supplies,” she said. Wiedenbeck said that besides using the standard cement casing at the gas-drilling site to protect underground water sources, a second cement casing will be used for added protection.

She said the casings are inspected regularly throughout the life of the well.

Encana’s zero tolerance of spills means its employees are specially trained for operating valves at drilling operations or transporting liquids, she said.

All spills are reportable, and the federal Environmental Protection Agency has a toll-free line to report them at (877) 919-4372.

“We are very proud of our environmental record,” she said.

To be prepared, residents within a mile radius of the drilling sites are advised to have their well water tested, Wiedenbeck said.

The trick is knowing what kind of testing is needed and the proper way to take a sample.

Aqua-Tech Laboratory Director Joseph F. Calabro, Mountain Top, said well water owners should have a state Department of Environmental Protection-certified lab do the testing. Someone who is certified with the lab should draw the water and a chain of custody for the water sample should be followed, he said.

A chain of custody for the sample is a log that is signed and dated by the person taking the water sample and given to the lab, where it is signed and dated upon receipt. Calabro said this log will stand up in court.

A listing of state-certified labs, by county, can be found at http://water.cas.psu.edu. Click on “information” on water issues related to Marcellus drilling. Then, on the right side of the screen, click on “find a lab.”

Calabro said homeowners should know what is normally in their well water. He said small amounts of minerals such as barium, sodium, manganese and iron, are already in well water, along with many other minerals.

He said that once this baseline for what’s in the water is established, then testing for industry-specific indicators can be performed.

He advised that if homeowners notice a change in taste, clarity or smell of their water, they should have it tested right away.

Concerned that nervous residents could be charged for more testing that what is really needed, he said he is willing to attend municipal meetings to discuss minerals and industry-specific indicators to watch for.

Wilkes University geologist Brain Ora said he is hoping homeowners will be willing to share their testing results to compile a database, by zip code, to show water quality history. He said that over time the database will track changes of water quality.

Mar. 24–The discovery and development of the Marcellus shale natural gas deposits has been big news in Pennsylvania and neighboring states for several reasons.

One is the massive energy resource it represents. Another is the jump in jobs it could create. A third is the tax revenue that might be reaped. And one more is the concern that widespread drilling poses for the environment.

That worry covers a range of issues, but a major one to catch the eye of the Environmental Protection Agency is “fracking,” the hydraulic fracturing technology that breaks the rock deep in the ground to release the gas. The process injects millions of gallons of water mixed with chemicals and sand under great pressure into a gas well to crack the shale. How should drillers best dispose of this water?

While fracking has been used for decades at shallow depths, the EPA said last Thursday it would do a $1.9 million study of the potential adverse effects of the process at a mile or more underground. The EPA wants to gauge the impact on water quality and public health — and that makes this money well spent.

In Pennsylvania alone, 2,500 drilling permits were issued by the state for Marcellus shale gas wells between 2007 and 2009, with another 5,000 expected this year. The Marcellus Shale Coalition, a trade group, says 1,100 Marcellus shale wells have been drilled so far, as a way to get to some of the estimated 363 trillion cubic feet of natural gas.

While the coalition and others in the industry say they are committed to ensuring a safe approach to treatment and disposal of wastewater due to fracking, it’s good to know the EPA study will provide an objective, scientific view on how well they are doing.

It’s unfortunate the study could take two years to complete, but Americans should be willing to sacrifice speed for thoroughness on a question that involves community health.
