For over 5 years, DCS has been reporting on, and fighting, the practice of spreading toxic fracking wastewater on unpaved roads for “dust control”. Mr. Hess, in the article below, references DCS’s reporting on this issue. Another DCS post includes a map of unpaved roads in PA, which are potential dumping grounds for toxic fracking wastewater.
Unpaved roads in PA

The health hazards of dumping toxic fracking wastewater on unpaved roads is one reason why the DRBC must ban the import of frack waste into the Delaware River Basin.
A new study by Penn State researchers to be published in the journal Science of The Total Environment found oil and gas drilling wastewater is far less effective than commercial products at suppressing dust, is easily washed off roadways into nearby streams and fields and contains pollutants that can negatively affect human health, agriculture and aquatic life.
The authors of the study include Dr. William D. Burgos from Penn State’s Department of Civil and Environmental Engineering who provided the conceptualization and methodology and the formal analysis for the study, including validation, supervision, writing, reviewing and editing the article.
Researchers tested the effectiveness of oil and gas drilling production wastewater (OGPW) from several states against three commercially available dust suppressant products including waste soybean oil, an EnviroKleen product approved by the PA Center for Dirt And Gravel Roads and water treatment plant softening sludge.
Oil and gas wastewater was collected from eight different conventional and unconventional wells in Pennsylvania, Ohio and Wyoming.
The wastewater and alternative products were tested in a laboratory setting on simulated dirt and gravel roads and then subjected to small simulated rain events.
Among the findings of the study were–
— OGPW Was Orders Of Magnitude LESS Effective At Controlling Dust: Both the soybean oil and EnviroKleen product performed “three orders of magnitude better” than the best performing oil and gas wastewater samples. (page 7, Section 4.1)
— OGPW Application For Dust Suppression May Not Be Beneficial: Dust suppressants used commercially, such as calcium chloride, magnesium chloride and EnviroKleen, as well as the alternative soybean oil each outperformed all oil and gas drilling wastewaters tested in this study, “which may indicate drilling wastewater application for dust suppression may not be beneficial.” (page 8, Section 4.2)
— OGPW Lost Efficacy More Quickly Than All Suppressants After Small Rain Events: The study said even after small simulated rain events all suppressants lost efficacy, but oil and gas drilling wastewater “lost efficacy more quickly and to a greater degree than” the alternatives. (page 8, Section 4.3)
— OGPW Lost Nearly All Sodium, Magnesium, Calcium After Small Rain Events: OGPW testing also found that small simulated rain events leached out all sodium, magnesium and calcium from the road aggregate in runoff making it the most susceptible to these losses than the other alternatives. (page 8, Section 4.3)
— OGPW Contains Radioactive Radium Above Regulatory Standards: Oil and gas drilling wastewater “contains levels of radium above regulatory standards, such as the industrial discharge limit of 60pCi/L.” (page 8, Section 4.4)
–– Pollutants In OGPW Raise Concerns Over Safety Of Water Resources After Application: The article noted “additional contaminants found in OGPW, i.e. lead, arsenic, radium, may accumulate on roadways and in groundwater, which raises concerns about the safety of water resources post-application.” “Indeed, brines that are used for road maintenance activities such as deicing and dust suppression raise concerns about increasing the salinity of proximate water resources, because once applied, much of the salt becomes mobile and travels offsite with surface and groundwater which has negative consequences for agriculture, infrastructure and aquatic life.” (Page 8, Section 4.5)
— Soybean Oil Most Promising Alternative: The article said soybean oil is perhaps the most promising alternative product to oil and gas drilling wastewater because it worked as well as a commercial product and could likely be obtained at a lower price, although other impacts from its application were not evaluated in this study. (page 7, Section 4.1)
Conclusion Of The Study
“Road spreading of OGPW is an established practice that is generating health and efficacy concerns as the practice gains more attention.
“Compared to commercial counterparts, calcium and magnesium chlorides, the presence of sodium in an OGPW can render an OGPW less effective as a dust suppressant.
“None of the OGPWs assessed [in this study] performed as well as the commercial analogs, CaCl2 or MgCl2.
“If the justification for using OGPW is equivalency with commercial counterparts, evidence points to far less efficacy.”
One other helpful aspect of this new Penn State study is footnotes and references in the journal article contain links to many other studies of oil and gas drilling wastewater that support the conclusions in the study and document the harmful nature of pollutants in the wastewater.

Importance Of This Study
DCED’s PA Grade Crude [Oil] Development Advisory Council is scheduled to meet August 19 to discuss the issue of road dumping conventional oil and gas drilling wastewater and the status of Penn State research on the issue. Read more here.
The results of this new Penn State study show clearly that road dumping of drilling wastewater is just that– dumping– with little effective dust suppression benefit.
A second new study released last week from researchers from the Technical University Of Munich say there is a clear link between exposure to airborne or waterborne particles and several health conditions through the breakdown of the mucosal system, the body’s first line of defense from infections and toxins. Read more here.
Residents where road dumping is occurring in Pennsylvania have complained for years of a variety of health-related problems. Read more here.
Other recent research by Penn State and others has shown the road dumping of wastewater from oil and gas wells as a dust suppressant is not only NOT effective, but contaminates the roads and wash sediment and pollutants into nearby streams.
There has also been other research pointing to not only environmental but also health impacts from using oil and gas well wastewater for dust control. Click Here for a summary (by DCS).
Another recent study found that between 1991 and 2017, 240.4 million gallons of wastewater from conventional oil and gas wells were applied to roads, according to DEP records.
In October 2016, DEP adopted regulations prohibiting the road dumping of production wastewater from unconventional oil and gas wells for dust suppression, anti-icing and de-icing (Chapter 78a, Section 70), but did not address wastewater from conventional wells.
As a result of a 2017 appeal to the Environmental Hearing Board, DEP’s Oil and Gas Program imposed a moratorium on all road dumping of wastewater from wells in the state in 2018.
However, the road dumping of wastewater from oil and gas wells is still authorized under the DEP Waste Management Program under a co-product determination which allows the use of waste that has similar properties to commercial products as if it was that product.
This new Penn State study very clearly says oil and gas drilling wastewater is at least THREE orders of magnitude less effective at dust suppression than other commercial alternatives, which blows a big hole in the “co-product” determinations made by DEP over the years.
The road dumping of conventional drilling wastewater is pervasive and widespread in oil and gas areas in Pennsylvania and as a result DEP has an extremely difficult time taking enforcement actions to shutdown illegal operations. Read more here.
The 2019 Annual Report of the Crude (Oil) Development Advisory Council contains a special section devoted to the issue of oil and gas production water issues, including the goal of reinstating the road dumping program, leaving no doubt about their political intentions.
The conventional drillers have also supported legislation– House Bill 1144 (Causer-R-Cameron)– that would legalize the road dumping of drilling wastewater. House Republicans passed the bill in May and it is now in the Senate. Read more here.
Senate Republicans have their own version of the bill that would do the same thing– Senate Bill 534 (Hutchinson-R-Venango)– but it has not yet been considered.
