A Conversation With Fred Sinclair #1 Introduction / Water issues

I had the pleasure to sit down with Fred Sinclair for a few hours on a recent Saturday and asked him questions about hydrofracking and its potential impacts. I first met Fred during the fight against the siting of the radioactive waste dump in Allegany Co. and quickly came to respect his broad knowledge and expertise. In our conversation, Fred spoke on topics that will be the focus of my next three columns:  Water, Radioactivity, and Social Impacts.

Fred is currently an Allegany County legislator and is the chairman of the Planning and Economic Development Committee. For 35 years he was manager of the Soil and Water conservation district for Allegany County prior to becoming a legislator. He has a deep understanding of resource protection, water flow and hydraulics, interactions of water and earth, and subsurface geology. This knowledge combined with the larger social and economic perspectives of a legislator has given him the ability to see how the various issues related to hydrofracking – whether they be scientific, geologic, economic, or social, are all interrelated.

GM: The Village of Alfred, the Colleges, Tinkertown, parts of the Town of Alfred, the Alfred-Almond School, and the village of Almond all draw their water from one aquifer. If hydrofracking is allowed in our area should we be concerned?

FS: This type of aquifer is called an unconfined aquifer, meaning that it is related to the gravels and the recharge areas of the valley; considerable wetlands areas serve to recharge it and are hydraulically connected to it.
This is a fundamentally different situation than a confined aquifer that exists down below a big layer of clay that would tend to confine it from surface influences. Alfred’s unconfined aquifer has a lot of hydraulic connections, just like in your body, like the way veins are connected and go to many different areas. These water veins feed this aquifer and there is the potential for things that happen on the surface to penetrate down through and affect the aquifer readily. And it sits on top of bedrock that has its own characteristic patterns of significant fractures; that also collects water and feeds the aquifer. These are all possible pathways for pollution if drilling goes into one of these veins that feed a gradient that heads towards an aquifer. Alfred’s aquifer and well is very good and needs to be protected and having this huge population dependent on it ups the ante for the need to protect it.

GM: So given the geology you just described do you feel that hydrofracking in the area around the aquifer is a threat?

FS: Absolutely! And there is an additional issue here and that is airborne sources of pollution. You have to look at all of the trucking, hydrofracking engines at the well sites, and all of the developmental activities that come with drilling. Additionally, over a 12 month period 1 well is allowed to discharge 1 ton of benzene to the atmosphere. That’s only one well – remember a spacing unit between well pads is 640 acres – so every 640 acres there could be a well pad.
The DEC -- proposed solution to these emissions is to put 30-foot stacks up at the well pads. That is their solution! What happens when it rains and you get this atmospheric deposition of pollutants? It lands on watersheds, recharge areas, wetlands and foliage. It is part of the water that penetrates the earth and is recharging aquifers. Not to mention that it’s going to affect organic certification of fields. These emissions will also affect the more susceptible – people with breathing problems and those less able to cope with pollutants. Think about the BTEX complex [Benzene, Toulene, Ethybenzene and Xylene] coming off the condensate tanks. This wide blanketing of atmospheric deposition is not something the DEC has addressed.

GM: You describe a kind of aerial migration pathway to the aquifer, what about the drilling itself as a source of pollution?

FS: At the wellheads there will be large areas of extremely poisonous chemicals on site. There will be accidents. There will be illegal activity. There are examples in Pennsylvania of fracking fluids being spread on roads. That’s the human factor. There are many ways pollution can travel underground. First, when they begin drilling, before a pipe is inserted and grouted, they are using a caustic drilling “mud” and they are drilling down through aquifers. Second, when they drill into the Marcellus layer they then fracture the shale with an explosive force that exerts huge amounts of pressure, creating fractures that can connect to natural geologic pathways. It is absurd to think that gas and chemicals will only follow the designated channels. Four, it is proven that gas will follow along the outside of the pipe. Five, you have seals and grout in the underground pipeline. As long as they work you have a seal that will contain most of the gas, but they have a life and you have ground movement and the potential for seals to be interrupted, so who’s to say for how long they will function properly? There are actual field studies that show how long these seals work – they might last 10 years but inevitably there will be seepage and methane can accumulate in your water system and can be explosive. For us to think that we have everything all sealed off is naïve. The latest research of the USGS [United States Geologic Survey] has been damning in terms of what is happening out west. The DEC says our regulations will be better -- but with the forces at play we will find over time that these things will leak and there will be the introduction of pollutants into the aquifers.

GM: Up to 50% of the water that’s mixed with chemicals that goes down the hole of a well during the fracking process, doesn’t come back to the surface. The industry says it’s not a concern because it’s geologically sound down there and this material will be contained forever. Does the process of migration you’ve just described pertain also to this chemical-laced water?

FS: Yes. It could easily be carried up by man-made and geologic fractures. The earth and geology in western New York is very fractured already.

GM: What about the large number of abandoned gas wells in Allegany Co.?

FS: There are areas in the county where hundreds and hundreds of wells were drilled in a very small area and they just walked away from them when they didn’t hit anything – or they hit water. Not all of these wells are still seen at the surface, sometimes the pipe is rusted off and grass has grown over it. In the Allentown area there are zones where the homes do not have potable water, there are some spots where it is questionable if you should bathe in the water. Because of old drilling there are hydrocarbons in the aquifers – there are entire areas in the mostly southern part of the county where you cannot drill a water well. A lot of people don’t know that.

GM: It’s like you are describing swiss cheese. Are these old wells a threat to us in relation to hydrofracking?

FS: Absolutely. In many cases they are the connections between lower levels of geology and water. Those pipes are old enough that they are cracked and have lost their integrity, so if hydrofracking or a crevice of some kind was to reach them, they are a direct conduit to an upper aquifer.

An abandoned gas well in Elm Valley that now spouts water. What was intended to keep water out has now become a conduit for it.


GM: Are there other ways in which our water is threatened?

FS: Yes –what’s even more vulnerable than the unconfined aquifer that Alfred draws from is the Genesee River. The villages of Wellsville and Scio rely on water that comes right out of it. It is classified A Class, meaning it is potable water. We have contacted Potter County and their emergency managers and we have attempted to set up a direct line of communication between Pennsylvania and our water plant in Wellsville, so that if they have any inkling that a truck has turned over, or a bad actor has put stuff in a stream that is in the Genesee River watershed – there are several thousands of acres in Pennsylvania that feed directly into the Genesee River – we want to know immediately if something happens. It’s no small feat to get everyone understanding the importance of this. Immediate notification would enable us to close our water intake until it has passed by us.

GM: Does this arrangement leave you feeling confident?

FS: The human factor is one that does not create confidence.

GM: And what about further downstream from Wellsville?

FS: The other community that could be affected is the Village of Belmont. It has an unconfined aquifer just off the side of the Genesee and its water is associated with the river. If they were to know, action could be taken.

GM: And what happens further downstream from there?

FS: The DEC will tell you that dilution is the solution to pollution.
