The U.S. Geological Survey (USGS) has warned New York state regulators that their plan to allow drilling and hydraulic fracturing for natural gas in the Marcellus Shale could endanger private water wells, municipal aquifers and New York City’s drinking water supply.
The assessment of the USGS, widely regarded as impartial and authoritative on drilling issues, intensifies pressure on Gov. Andrew Cuomo (D-NY) not to proceed with a drilling plan drafted by the New York State Department of Environmental Conservation. Cuomo has pledged to “let the science and the facts make the determination, not emotion and not politics.”1
The U.S. Environmental Protection Agency (EPA) has separately written New York regulators arguing that they are ill-equipped to regulate a boom in shale gas drilling and have limited financial means to enforce the numerous new regulations they have proposed. The EPA has raised additional concerns, among them, that the state has understated the severity of radioactive pollution associated with drilling and doesn’t know how such contaminants would be disposed of.
Officials at the Department of Environmental Conservation are now considering whether to modify their plan to address the federal agencies’ reservations and about 60,000 letters from local governments, independent scientists, gas drillers, property owners, environmental groups and other interested citizens. Once the state agency has concluded its review, which could wind up as soon as this spring, the issue goes to Cuomo’s desk.
The stakes for New York taxpayers are enormous. The Department of Environmental Conservation has estimated that if New York City’s drinking water supply is contaminated by drilling, cleaning up the water would require a water filtration plant costing at least $8 billion, with a yearly operating expense of $200 million.2 Even then, city officials have said there is no guarantee that the water could be purified. If water supplies of other population centers are tainted, the cleanup costs would soar higher.
As now written, the state plan projects that tens of thousands of natural gas wells could spring up along the New York portion of the Marcellus Shale, a vast underground formation that stretches along the Appalachian chain as far south as Kentucky. Most of the wells are likely to deploy a relatively new shale-drilling process called high volume hydraulic fracturing and horizontal drilling, which typically involves injecting millions of gallons of water laced with chemicals into the ground under high pressure, aiming to crack shale rock and release natural gas trapped in small pockets.
The USGS, the federal government’s expert on the geology and hydrology of oil and gas drilling, advised New York regulators that their plan is flawed in several respects. Among them:
- The state’s proposal to prohibit drilling inside a 500-foot buffer around aquifers that supply major municipal water systems “is one-size-fits-all and may provide only partial protection to these aquifers.”3
- A similar 500-foot buffer for private water wells and springs “affords limited protection” and “does not take local geohydrologic conditions and topographic setting into account.” The USGS added that “changes brought about by drilling, including water quality changes, can be felt rapidly at significant distance from a disturbance—especially if a domestic well is [downhill] of a well pad.”4
- Pressurized fracturing fluids could migrate through underground faults and impact an underground aqueduct that carries drinking water to New York City. The USGS said that “the possibility of damage to the aqueduct from hydraulic-fracturing operations is an issue of concern” and deserves more study.5
- A map displayed in the state’s draft plan “grossly under-represents the number and extent of [natural] faults in the Appalachian Basin of New York” where shale gas drilling would occur. Ground that is riddled with underground faults could channel pollution from drilling into underground aquifers.6
- “Only scattered and incomplete information is available” on underground freshwater sources that could be polluted by shale gas drilling. The USGS said the state plan should require drilling companies to maintain detailed logs that would identify and protect these aquifers.7
Drilling too close to water sources
The USGS went to some lengths to dispute the state agency’s premise that drilling could be safely conducted 500 feet from water supplies. The federal agency said that in some cases, it might be necessary to prohibit drilling within five square miles of aquifers to avoid polluting them.8
The USGS position is bolstered by documented cases in Colorado, Ohio and Pennsylvania, where natural gas and related contaminants have polluted underground water supplies at distances much greater than 500 feet.
- In 2004, Canada-based Encana Corp. improperly cemented and hydraulically fractured a well in Garfield County, Colo. The state found that the poor cementing caused natural gas and associated contaminants to travel underground more than 4,000 feet laterally. As a result, a creek became contaminated with dangerous levels of carcinogenic benzene. The state of Colorado fined Encana a then-record $371,200. Despite more than seven years of cleanup efforts, as of last September, three groundwater monitoring wells near the creek still showed unsafe levels of benzene.9
- In 2007, a natural gas well fractured by Ohio Valley Energy Systems Corp. in Bainbridge, Ohio, caused natural gas to contaminate 23 nearby water wells, two of which were more than 2,300 feet from the drilling site.10
- In 2009, several natural gas wells drilled by Houston-based Cabot Oil and Gas Corp. in Dimock, Penn., polluted water wells used by at least 19 families, according to the state Department of Environmental Protection. Cabot has disputed the finding. At least three of the water wells were farther than 1,000 feet from the gas wells. For about two years, the Pennsylvania DEP ordered the company to deliver water to the families. Last December, Cabot stopped the deliveries after the DEP ruled that the company had met its obligations under a state order. Affected families were forced to scramble for new sources of water. Filmmaker Josh Fox, actor Marc Ruffalo and others donated bottled water that met some of the families’ needs. The federal EPA recently found dangerous contaminants in well water in Dimock and ordered a resumption of water deliveries for four of the families. Pennsylvania officials have declined to extend public water lines to the affected families, estimating the cost at $12 million.11
New York City water aqueduct threatened
The USGS concluded that under the state plan, hydraulic fracturing fluids could reach and damage New York City’s West Delaware Aqueduct, an underground tunnel that brings drinking water to the city from reservoirs in the Catskill Mountains. Naturally occurring fractures “may potentially provide pathways for the migration of pressurized fluids over significant distances,” the USGS wrote. It suggested that the state’s proposal to require site-specific permits in a 1,000-foot zone around the aqueduct might prove inadequate.12 The USGS focused only on threats to the West Delaware Aqueduct, one of several underground aqueducts that carry water to New York City from the Marcellus Shale region.
An earlier assessment commissioned by New York City’s Department of Environmental Protection (DEP) also concluded that drilling might endanger the West Delaware Aqueduct and other tunnels that carry the city’s water, for reasons similar to those cited by the USGS. The city’s DEP found that naturally occurring underground pathways near the tunnels “can extend up to seven miles laterally and up to 6,000 feet in depth.” It added:
“The vertical and lateral persistence of these features in conjunction with the potential for failed casings or other unforeseen occurrences could result in significant surface and subsurface contamination of fresh water aquifers, as illustrated by incidents in other well fields, most notably documented in Garfield County, Colorado (migration of toxic formation material through subsurface fractures) and Dimock, Pennsylvania (migration of natural gas to the surface via improperly cased wells). Similar mechanisms could permit migration of material into the fresh water aquifers that comprise the NYC West-of-Hudson watersheds and present potential risks to water quality and tunnel lining integrity.”13
Based on this assessment, the city agency recommended several preventive measures, including barring drilling within seven miles of several aqueducts and a drilling ban within two miles of other water tunnels.14
Underground faults, water supplies unmapped
The USGS raised serious questions about the state’s significant undercount of natural faults throughout the gas-rich Marcellus Shale formation. If drilling and hydraulic fracturing were permitted directly underneath faults, the federal agency said, contaminants could flow upward into underground aquifers. It noted that there are generally far more natural faults in bedrock overlying the Marcellus Shale than elsewhere.15
In a study that focused on the Marcellus Shale in New York and Pennsylvania and was published last year by the National Academy of Sciences, researchers from Duke University reported finding levels of natural gas an average of 17 times higher in water wells close to active natural gas wells than in water wells in non-active drilling areas. The most likely cause, they said, was leaky well casings, but they also raised the possibility that some gas migrated through “extensive fracture systems” in rock above the shale formations. Another factor, they said, might be gas migration through many older, un-cased wells abandoned during 150 years of drilling in Pennsylvania and New York.16
USGS urges better reporting
The USGS said that the depths of underground drinking water sources are not well documented and must be established so that drilling companies can design casing and cementing to prevent migration of gas or saltwater into underground drinking water supplies. The agency faulted New York state regulators for failing to require drilling companies to map underground fresh water and salt water sources and, as well, shallow gas formations before they drill extensively. It called these determinations critical to the design and installation of effective casing and cementing.17
Cuomo should emulate Maryland’s O’Malley
The USGS assessment makes clear that New York is not ready for shale gas drilling on any level. Given Cuomo’s commitment to science, it is hard to see how he could come to a different conclusion. Cuomo should halt the state’s drilling plan and let scientists like those at USGS continue their work so that New Yorkers can know whether high volume hydraulic fracturing and horizontal drilling can be conducted safely before drilling begins.
That’s essentially the approach Maryland Gov. Martin O’Malley has taken. His administration has embarked on a detailed study of potential drilling impacts, to be finished by 2014. Until then, O’Malley has committed not to allow gas drilling companies to deploy this controversial technique in Maryland’s portion of the Marcellus Shale.18
Meanwhile, the EPA is conducting a nationwide study on hydraulic fracturing’s impact on water and a separate inquiry in Pavillion, Wyo., where the agency concluded in a draft report that hydraulic fracturing likely contaminated groundwater on which the community relies for its drinking water and agricultural needs.
By proceeding with drilling in the face of warnings by USGS, the EPA and other experts, “Cuomo would be betting nothing of significance will go wrong,” Albany Times-Union columnist Fred LeBrun wrote in a Jan. 15, 2012, column. “Given the enormity of the possibilities, that’s a dumb bet.”19
Will Cuomo make a multi-billion-dollar gamble with the state’s drinking water and the health of New Yorkers? The upside, in the form of jobs and revenues from gas production, is modest. The downside, if anything goes wrong, is incalculable. Why chance it?

The conclusion to decades of work to remove a dam on the Middle Fork Nooksack River east of Bellingham, Washington began with a bang yesterday as crews breached the dam with a carefully planned detonation. This explosive denouement is also a beginning.
The History<p>The Middle Fork Nooksack drains glacier-fed headwater streams that run off the icy summit of 10,778-foot Mt. Baker. The Middle Fork joins the North Fork and then the mainstem of the Nooksack River, which travels to Bellingham Bay and Puget Sound. The entire Nooksack watershed stretches 830 square miles across Washington and into British Columbia.</p>
A Plan Comes Together<p>The Middle Fork dam is not a pool dam built for water storage. Much of the time, water flows over the top until dam operators drop a floodgate to divert water to new locations. That water travels about 14 miles through tunnel and pipeline to Mirror Lake, then Anderson Creek, and to Lake Whatcom before finally being delivered to residents' taps.</p><p>Before removing the dam, engineers had to move the water intake 700 feet upstream and situate it at an elevation that still enabled city water withdrawals throughout the year, regardless of flow conditions.</p><p>They also needed to make sure that the rushing water didn't sweep up fish and accidentally send them through the water-supply system.</p><p>"The solution required a fairly complex design in the intake structure, including a fish exit pipe out of that structure to put fish back into the river in a way that meets current environmental permit standards," explains LaCroix.</p>
Project layout for the removal of the Middle Fork Nooksack diversion dam and rebuilding of water intake. City of Bellingham<p>Despite the cost and the work, she says, being able to continue to meet their municipal water obligations while opening up habitat for threatened species has been a win-win.</p><p>"I think there's a lot of benefits to having a dam removal versus fish passage — the main one being that you get a free-flowing river that can be a dynamic ecosystem and change over time," she says. "A static fish ladder just can't provide that same level of ecosystem benefit."</p>
Restoration Success<p>Despite local authorities' championing dam removal on the Middle Fork, the project has largely flown under the radar, overshadowed in the Pacific Northwest by heated discussions about a much larger potential project — removing <a href="https://www.seattletimes.com/seattle-news/feds-reject-removal-of-4-snake-river-dams-in-key-report/" target="_blank">four federal hydroelectric dams on the lower Snake River</a>, a major tributary of the Columbia River.</p><p>Proponents of dam removal there see it as the best chance for recovering threatened salmon populations, including Chinook, which could help starving Southern Resident killer whales. Those dams also provide irrigation water, barge navigation and hydropower, so there's been more pushback against removal efforts.</p><p>Previous dam removals around the country, however, have proved successful at aiding fish recovery and river restoration.</p><p>Most notably the 1999 demolition of <a href="https://therevelator.org/edwards-dam-removal/" target="_blank">Edwards Dam on Maine's Kennebec River</a> restored the annual run of alewives, a type of herring essential to the food web. The fish run has gone from zero to 5 million in the two decades since dam removal. Blueback herring, striped bass, sturgeon and shad have also extended their reach. And the resurgence has brought back osprey, bald eagles and other wildlife, too.</p><p>The overwhelming success of river restoration on the Kennebec helped to spur a nationwide dam removal movement that's now seen 1,200 dams come down since 1999. Last year a record <a href="https://www.americanrivers.org/conservation-resource/a-record-26-states-removed-dams-in-2019/" target="_blank">90 dams</a> were removed in 26 states, including <a href="https://therevelator.org/cleveland-forest-dam-removal/" target="_blank">20 dams in California's Cleveland National Forest</a>.</p>
Spider excavators remove on dam on San Juan Creek in California's Cleveland National Forest. Julie Donnell, USFS<p>The results have been seen in the Pacific Northwest, as well, which boasts the largest dam removal thus far in the country. In 2011 and 2014, the demolition of <a href="https://therevelator.org/elwha-dam-removal/" target="_blank">two dams</a> on Elwha River, which runs through Washington's Olympic National Park, opened up 70 miles of habitat that had been blocked for a century. Scientists have started seeing all five species of salmon native to the river coming back, particularly Chinook and coho. Bull trout, they've observed, have increased in size since the dams were removal.</p>
Benefits on the Middle Fork Nooksack<p>McEwan hopes to see a similar outcome on the Middle Fork.</p><p>Like the Elwha the Middle Fork Nooksack is a relatively pristine river with little development, and dam removal is expected to provide a big boost to fish. The additional miles of spawning habitat are important, but so is the temperature of that water.</p><p>The dam removal will open access to cold upstream waters, which are ideal for salmon and getting harder to come by as climate change warms waters and reduces mountain runoff.</p><p>"This is really great for the climate change resiliency for these species," says McEwan.</p><p>Steelhead will get back 45% of their historic habitat in the river, and scientists expect Chinook populations to increase in abundance by 31%.</p><p>That <em>could</em> help Southern Resident killer whales.</p><p>"When you get to the ocean, it's a little bit of a black box in terms of what you can model and say definitively is going to help, but more fish is better for orcas," McEwan says.</p><p>Upstream habitat will see benefits, too.</p><p>Oceangoing fish like salmon enrich their bodies with carbon and nitrogen while at sea. When they return to their natal rivers to spawn and die, the marine-derived nutrients they carry back upriver become important food and fertilizer for both riverine and terrestrial ecosystems — aiding everything from trees to birds to bears.</p><p>"Once the fish start making their way back, it will start changing the whole ecological system," says Delgado.</p><p><span></span>But any ecological benefit from salmon restoration, either in the ocean or the upper watershed, won't be immediate.<br></p><p>"The population of salmon on the Middle Fork is so low that we expect it's going to take quite a while to rebound," she says. "But the big picture is that what's good for salmon is good for the region — our history and our destiny are intricately intertwined."</p><p>After decades of work, that process of restoration has finally begun.</p>

It can grow to a maximum of six inches (16 centimeters), change color depending on mood and habitat, and, like all seahorses, the White's seahorse male gestates its young. But this tiny snouted fish is under threat.
Building an Ocean Seahorse Destination<p>Seahorses are found in tropical and temperate coastal water worldwide, but are most abundant around Australia, China and the Philippines. </p><p>Trade in the tiny creatures is strictly regulated because of their use in traditional medicine, aquariums and their sale as dried curios. But because they are poor swimmers and cannot easily move elsewhere, habitat loss is a particular threat for these curious animals. </p><p>Seahorses wrap their tails around seagrass and corals to avoid being carried away on currents. They use the habitat to spawn and hide from predators such as crabs, while also feeding on riches of plankton and small crustaceans living in the reef.</p><p><span></span>Where corals aren't available, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/aqc.1217" target="_blank">scientists</a> found seahorses taking up residence in fishing nets and old crab traps abandoned at the bottom of the ocean. </p>
Mixing With the Locals<p>Baby seahorse mortality is high in the wild because they are easily caught, so those bred in the protected environment of the aquarium weren't ready to be released into the wild until early May.</p><p>The team released 90 new arrivals into Sydney Harbor, placing some directly into the purpose-built hotels, and others onto a net that wild seahorses had already settled on.</p><p>Before setting them free, the researchers marked each young seahorse with a fluorescent tag with unique IDs inserted just beneath the skin to track how they get on in the different environments. </p><p>"The most exciting part was being able to put these animals into the wild and then go back a month later and still see them surviving and growing," said McCracken. </p><p>The seahorses will be old enough to mate and reproduce around October or November 2020. And researchers hope that by then, they will be able to breed with the wild population. </p>
Building a Global Seahorse Hotel Chain<p>With seahorses everywhere facing the loss of their coral reef homes, similar projects have sprung up in places like Greece and South Africa, home to the world's most endangered seahorse, the Knysna seahorse. </p><p>"The endangered South African seahorse is benefiting from something quite similar, even though it wasn't intentional," said Peter Teske, professor at the Department of Zoology, University of Johannesburg.</p><p>In the South African <a href="https://www.researchgate.net/publication/322649251_An_endangered_seahorse_selectively_chooses_an_artificial_structure" target="_blank">case</a>, seahorses have bedded down in "Reno mattresses" — wire cages filled with rocks — that were used to build a new marina. Researchers from NGO Knysna Basin Project found the structures acted as a refuge for the animals.<span></span></p><p><span></span>While Teske describes the seahorse hotels as "a positive news story" and a great way to create public awareness of conservation, he added that establishing artificial habitats in some areas will only prevent the extinction of local populations.</p><p>"For a complete recovery, it is necessary to give the natural habitat a chance to regenerate," said the seahorse expert. </p>
Underwater Mascot<p>In Australia, the researchers hope the project could provide an opportunity to raise awareness not only of the plight of the Sydney seahorses but the other animals with which it shares its ocean habitat.</p><p>The waters around Sydney and the east coast are rich in biodiversity and include several threatened species like the weedy seadragon — a relative of the seahorse — and the grey nurse shark. Like the seahorse, they're also under pressure from pollution, ocean traffic and habitat loss through storms and coastal construction. </p><p>"It's a good thing to get people's support and interest. The seahorses are a useful vehicle to get people concerned if the harbor is in trouble," said David Booth, professor of marine ecology at the University of Technology Sydney who is also working on the project. </p><p>The hotels have become an attraction for divers hoping to catch a glimpse of these small but near mythical creatures. </p><p>"Everyone loves seahorses," added Booth, "they are so popular." </p>
