A Reader’s View
Domestic, industrial and agriculture water use is rising across Canada, putting many rivers and lakes under increasing strain. As an organization that works to protect natural areas across P.E.I., Island Nature Trust is concerned that any increase in the number of high-capacity groundwater wells will affect fish and wildlife in the province negatively. How much water can be withdrawn while still maintaining healthy natural aquatic ecosystems? It takes the expertise of hydrologists, engineers and biologists to understand and predict the changes in fish habitat in response to altered flow regimes/water systems.
Conservation practices such as longer crop rotations that include forages, better residue management and strip cropping increase the moisture holding capacity of the soil. The presence of organic matter enhances the soilʼs structure, thermal, and nutritional regimes; and decreases wind and water erosion. Healthy soils hold moisture better than those with low organic material. In other words, soils with high organic matter need less water for healthy plant growth.
Withdrawing water from existing ground water supplies at times of the year when those water levels are at their lowest and at a time when 100 per cent of the surface water flow is from groundwater (springs) will further reduce the volume of ground water flowing into springs, streams, rivers and estuaries. Reduced water flow coupled with high levels of nutrients currently found in the very potato-rich watersheds to be irrigated in central P.E.I., will lead to increased over-nutrification of water systems and then to an increase in anoxic events.
Wildlife in all parts of waterways will be affected by less water and by the associated issues such as eutrophication and anoxia. Extracting more groundwater from P.E.I. is about so much more than simply water volume issues. The permanent loss of high volumes of water in an already fragile aquifer at a very sensitive time of year will have negative impacts on aquatic animals and plants, including those harvested by humans.
Human health is important, and the high nitrate level found in groundwater in many wells in high potato production areas is a serious concern to the health of Islanders. However, wildlife and natural areas often take a back seat to human needs and health issues. In many jurisdictions fish and wildlife management agencies sit on the sidelines of important water management decisions.
On behalf of the health of our natural systems, including springs, streams, rivers, their riparian zones and estuaries we strongly encourage the P.E.I. Government to adopt a provincial water management plan to effectively integrate water quantity, quality and wildlife management and to maintain the existing moratorium on high-capacity deep water well construction.

At first glance, from New Brunswick, this headline sounded at-least-not-bad:
Impact of shale gas development on groundwater to be studied
New Brunswick Energy Institute investing $500K in two-year study, set to begin in April
Here are more details on the proposed NB study. It sounds like this intends to be little more than an assessment of baseline conditions of well water, with a focus on naturally-occurring methane contamination. In itself, that is not such a bad idea, but it is hard to see what good would come of this given they will presumably not be establishing baseline measurements for the various toxic chemicals actually used in fracking and/or liberated from deep underground as a result of fracking (e.g., heavy metals, radioactive elements, etc.). Also troubling is that this will likely be used to distract us from the many other risks and impacts associated with a shale gas industry (air pollution, habitat damage, surface water pollution, noise pollution, waste water pollution, etc.). –Brad
Testing Energy institute to spend $500,000 over two years to develop water quality baselines in four areas in southern New Brunswick that are earmarked for possible shale gas development
JOHN CHILIBECK TELEGRAPH-JOURNAL, March 18, 2014
FREDERICTON – The New Brunswick Energy Institute plans on spending more than $500,000 on research looking at well water quality in areas where industry wants to develop shale gas.
The institute, under fire for being funded by a pro-development Tory provincial government, said Monday the research would go toward establishing a proper baseline before any more wells are drilled.
It will take place in four areas of southern New Brunswick where exploration or development of the controversial industry is underway: Sussex-Petitcodiac, St. Antoine-Shediac, Harcourt-Richibucto and Boisetown-Upper Blackville.
Kerry MacQuarrie, a civil engineering professor at the University of New Brunswick, was selected as the project lead for the two-year study on about 500 private wells.He said it was important to find out the water quality before any further development takes place because sometimes people don’t realize there’s naturally occurring pollution with no human cause.
“This will be totally voluntary and it will be up to the homeowners that we contact whether they want to be involved”MacQuarrie said in an interview. “I would assume that people would be interested to know what the quality is for their drinking water, but there won’t be any obligation for anyone to take part.”
MacQuarrie is well aware of the controversy surrounding the industry and the institute itself. Between opinion polls and the province’s two major political parties, New Brunswick society appears to be split on the merits of shale gas development, which relies on hydraulic fracturing. The long-term consequences of fracking are still not completely understood,with critics,such as the Liberal opposition, saying a moratorium should be in place until more studies can be carried out, whereas the Tory government and other shale gas supporters argue that development, with certain safeguards, should go ahead to create more jobs and wealth.
“This is a research study, and it’s not really linked to any particular interest group or industry group,” MacQuarrie said. “I have no links with the shale gas industry or anything like that. I’ve been doing ground water research in the province for over 20 years and I publish that in peer-reviewed scientific formats. People probably will take issue that it’s related to the shale gas issue, but I think it’s something worthwhile to do because it seems a lot of the concerns that have been raised are related to ground water quality and the potential impacts on that.”
Stephanie Merrill,freshwater program director with the Conservation Council of New Brunswick, works for the environmental organization that has campaigned heavily to stop shale gas development. She welcomed the idea of further study Monday, though she qualified her support by saying she would have to first see a detailed work plan and explanation of the research methods.
She agreed that baseline studies were important, all the more reason, she said, for a moratorium on exploration and development.
“There should be a decision made right now to halt the further work of companies’ with exploration leases and licences while this kind of work is undertaken. That would go a long way in providing an increased level of trust with the public, so they can put aside the question of whether the work is supporting the industry versus having information for providing good solid information for whether the industry should go ahead”
MacQuarrie acknowledged the researchers would have a bit of trouble with their baseline data if the industry continues to develop over the next two years.
“I have no idea to predict what the industry might do in the next couple of years,but I’m guessing it would only be a handful of wells, perhaps, that might be drilled. But again, I have no inside information or any clue about that.”
The team, which will consist of MacQuarrie and as many as eight research students, will send mail-outs or hold meetings to pick about 500 private well owners in the select areas. To ensure their results are not contaminated, they want to establish their baseline using wells that are at least one to two kilometres away from any existing oil or gas wells or seismic tests that have already been conducted. Natural gas is currently extracted at the McCully fields near Sussex and dozens and dozens of different hydrocarbon wells have been drilled since the 19th century,most of them now abandoned.
The researchers want to look at newer private water wells built within the last 20 years when provincial regulations became stricter and data was collected on the wells. They also want sites that are nicely spaced apart with different geology so that they get a better variety and breadth of data. The study will run from April 2014 to April 2016, when a final technical report will be submitted.
The project will be the first large-scale examination of natural methane gas occurrences in private water wells in the province, with the objective to collect and report baseline domestic water quality data. The focus is on groundwater quality parameters that are most relevant to the potential impact on shallow groundwater from unconventional shale gas production.
Early results from the project will be provided in an interim progress report on the institute’s website. It is intended on being the beginning of a series of water studies that the institute will be funding relating to energy development.
MacQuarrie described the work as labour intensive and requiring a good deal of expertise to properly obtain and analyze samples.He said they’d probably work in concert with researchers at Université de Moncton, who have already begun work on collecting data on wells that might be contaminated by radioactive materials caused by deposits such as uranium.
The institute plans on spending $532,000 overall on the study.
