The safety of fracturing fluids – a quantitative assessment

The Safety of Fracturing Fluids – A Quantitative Assessment
by Steve Coffman, member of the Committee to Preserve the Finger Lakes --
August 4, 2009
In response to a FOIL request to New York State’s Department of Environmental Conservation, the
Committee to Preserve the Finger Lakes received a list of 48 toxic substances (as defined by the DEC or
EPA) permitted for use in hydraulic fracture drilling of gas wells in the Marcellus Shale formation in Yates,
Schuyler, Steuben, Broome and Cortland Counties. The received materials came in the form of documents
submitted by the drilling companies themselves: Material Safety Data Sheets (MSDS) and Company Drilling
Data Sheets.
The Hazardous Materials Identification System was developed to help employers comply with OSHA
standards. The MSDS documents have the Hazardous Materials Identification System (HMIS) ratings for
most of the 48 products. Additionally, extensive data is presented for each product about its chemical
composition.
Some of the products listed in the documents are antimicrobials, microbiocides, corrosion inhibitors,
surfactants, hydrochloric acid, and liquid nitrogen. Very low doses of some of them can cause cancer,
damage kidney and immune systems and affect reproductive development. Some of them are very harmful
to plant and marine life. Many are highly flammable.
Gas drilling companies say they use such tiny amounts of chemicals in the drilling---of the million or so
gallons of liquid pumped into a well, only one percent or so are chemicals, and that they are diluted beyond
harmful levels. But on some fracturing sites that tiny percentage of one percent translates to 5,000 or more
gallons of chemicals highly concentrated in a few acres.
Method
While all 48 products received from DEC are toxic to some degree, this analysis limits its scope to 34
materials that are highly toxic in one or more ways, or that have specific relevance to the drilling operations
in Part II.
Part I describes these products in terms the toxic chemicals they contain, their use, precautions,
decomposition dangers, and methods of disposal. [Numbered “NOTES” provide additional information on
toxicity of certain chemicals within these described products.]
Part II describes the use of toxic chemicals, also information about water use and disposal, as reported
from the 12 gas drilling operations that, according to DEC, have taken place in the Marcellus Shale
formation in Yates, Schuyler, Steuben, Broome and Cortland Counties.
Part III provides a brief summary and poses some of the obvious questions prompted by this information.
Disclaimer: While several members of the Committee to Preserve the Finger Lakes have strong industrial
engineering backgrounds, none of the members is a chemist, geologist or a gas drilling expert. The purpose
here is not to present ultimate answers, but rather to pose important and necessary questions about the
safety of these products; not only to the humans directly exposed to these materials, but also in the air and
water of our region’s environment. All of the information presented herein comes from the companies
themselves, either from the DEC or from other Material Safety Data Sheets.
Note: The “Composition” of products refers only to listed toxic ingredients as supplied in company MSDS.

(short-term) or chronic (long-term) exposure of humans to methanol by inhalation or ingestion may result in
blurred vision, headache, dizziness, and nausea. No information is available on the reproductive,
developmental, or carcinogenic effects of methanol in humans. Birth defects have been observed in the
offspring of rats and mice exposed to methanol by inhalation.

NOTE 8. Aromatic hydrocarbons
U.S. Public Health Service statement “How can polycyclic aromatic hydrocarbons [PAHs] affect my
health?”-- PAHs can be harmful to your health under some circumstances. Several of the PAHs . . . have
caused tumors in laboratory animals when they breathed these substances in the air, when they ate
them, or when they had long periods of skin contact with them.
Studies of people show that individuals
exposed by breathing or skin contact for long periods to mixtures that contain PAHs and other compounds
can also develop cancer. Mice fed high levels of benzo[a]pyrene during pregnancy had difficulty

PART II ANALYSIS OF GAS DRILLING SHEETS FOR MARCELLUS
SHALE WELLS IN YATES, SCHUYLER, STEUBEN, BROOME
AND CORTLAND COUNTIES
For the five counties requested, DEC provided Drilling Sheets for 14 gas drilling operations in the Marcellus
Shale formation. Of the 14, only 12 were hydraulically fractured, and only one of those 12 was “slickwater”
fractured.
In this analysis, all hydraulically fractured wells are analyzed for: 1) Amount of fresh water used; 2) Water
source; 3) Additives used; 4) Amount of return fluid; 5) Percentage of return fluid; 6) Method of
disposal; 7) Time of drilling operation from site construction to site reclamation.
In addition, several notes have been added for chemical products used that were not included on DEC’s

PART III -- SUMMARY & QUESTIONS
SUMMARY
Drilling sheets on 14 wells were received. 12 of the 14 were stimulated (11 were “Nitrified,” one, Frost 2-2,
was “slickwater fractured.”).
Average amount of fresh water used for the 11 non-slickwater wells: 93,163 gal.
(Range: 15,078 gal. - 263,340 gal.)
Amount of fresh water used for “slickwater” fractured well: 640,550 gal.
(690% increase over non-slickwater wells)
Average amount of frac water returned (from 9 wells providing that information): 41%.
Number of different toxic chemical products used: 34.
Number of products (in MSDS) hazardous to aquatic environments: 21.
Number of products (in MSDS) whose aquatic toxicity is undetermined: 11.
Average time from site construction to site reclamation: 75.
QUESTIONS (by no means meant as an exhaustive list)
1. QUESTION: How is it that Multifunctional Surfactant F-15 [No. 16] can be disposed of via “Injection or
other acceptable method in accordance with local regulations” when one of its ingredients, butan-1-ol entails
the caution: “Avoid runoff into storm sewers and ditches which lead to waterways. Butanol should not bind
strongly to soil and so is expected to leach into groundwater . . . RCRA U-Series:: waste number U031
(Ignitable waste)”?
2. QUESTION: (similar to Q. 1) Why is it that FE-105 and Gas Perm 1000 can be disposed of “according
to federal, state and local regulations,” when both contain Isopropanol (See Note 12), which is separately
required to be disposed of according to RCRA Hazardous Waste Code D001 (ignitable waste)?
3. QUESTION: How adequately can the local and regional treatment plants remove the toxicity (and brine)
from millions of gallons of frack fluid before returning it benignly to local water supplies?
4. QUESTION: If only 41% of fracking fluid is recovered, what happens to the other 59%? Is it contained?
Flowing loosely underground? Seeping out?
5. QUESTION: Given the strong suspicion of a connection between gas drilling in the Texas Barnett Shale
and seismic activity [See work of Dr. Chris Hayward, geophysics research projects director at SMU], what
surety can there be that contained fluids will remain contained and not eventually infect area aquifers and
waterways?
6. QUESTION: As to the recovered fracking fluids---given that, according to MSDSs, 30 of the 34 toxic
products in this report may be disposed of “according to local regulations,” what uniformity is there among
“local regulations” that would give confidence that those 30 products will be adequately treated before being
released back into public waters?
7. QUESTION: Given that, of the 13 hydrofracked wells in this report, 11 of them disposed of their returned
fracking fluids in Pennsylvania, who is responsible for proper oversight of these toxic materials? The
localities of Athens, Franklin and Sayre PA? The lead agency NYS DEC? PA DEP? EPA---despite
exemption of hydraulic fracturing from EPA oversight, is this not interstate commerce? Susquehanna River
Basin Commission? Who is responsible for making sure that these water treatment facilities are capable of
treating all the chemicals contained in fracking fluids, as well as the brine and other contaminants in the
return waters? Who is responsible for their quality control?
8. QUESTION: For the 11 products whose aquatic toxicity has yet to be determined, should the
determination not be made before they are disposed to water treatment plants for ultimate return into the
aquatic environment?
This report was prepared by Steve Coffman, a member of the Committee To Preserve The Finger Lakes -- August 4, 2009.
