Does hydraulic fracturing contaminate drinking water?

FACT: Fracking does NOT Contaminate Drinking Water The report found that there is “no evidence of widespread, systemic impacts on drinking water” as a result of the fracking process. Another study corroborated the EPA’s findings.

How does hydraulic fracturing contaminate groundwater?

There are many pathways to pollution from fracking. After the well is fracked and starts producing oil and gas, much of the fracking fluid remains underground where it could potentially contaminate groundwater if fractures connect to aquifer systems.

Does fracking contaminate surface water?

Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals.

Is hydraulic fracturing exempt from the Clean Water Act?

Fracking is exempted from the Safe Drinking Water Act pollution control measures unless diesel is used in the fracking process. Oil and gas operations are exempt from important permitting and pollution control requirements of the Clean Water Act, including the stormwater runoff permit requirement.

What happens to water used in fracking?

Produced water is often disposed of by injecting it into deep geologic formations via wells that are specifically designed for that purpose. In some cases, produced water can be treated and reused to hydraulically fracture another well.

Is fracking water toxic?

However, the practice may come with a significant public health consequences, warn critics of fracking, noting that the process has the potential to contaminate drinking water supplies with toxic chemicals.

Does fracking damage groundwater?

In fact, scientists and researchers from governmental organizations, universities, and nonprofits confirm that fracking does not contaminate groundwater.

How does fracking affect the hydrosphere?

Fracking also results in significant ef- fects on hydrosphere including freshwater consumption, wastewater pollution, evaporation and transpiration, and local hydrologic cycle.

What are the effects of fracking on groundwater?

Fracking damages the environment, threatens public health, and affects communities in ways that can impose a multitude of costs: Drinking water contamination – Fracking brings with it the potential for spills, blowouts and well failures that contaminate groundwater supplies.

What’s in fracking water?

Fracking fluid is 99.5% water and sand. 0.5% is made up of safe chemical additives, most of which are found in common household products, like toothpaste and makeup remover, or in the foods you eat.

What exemptions did the 2005 energy bill give hydraulic fracturing?

In 2005, a national energy bill included the exemption of hydraulic fracturing from the Safe Drinking Water Act. This bill passed, with the exemption, although it left the door open for the EPA to regulate the use of diesel in hydraulic fracturing operations.

Does fracking remove water from the water cycle?

Fracking fluid and produced water gets mixed together. In the U.S., nearly all of this wastewater is injected into disposal wells. These deep wells are designed to prevent the water from escaping and contaminating drinking water aquifers, surface water, and ecosystems.

How does hydraulic fracturing use water in Michigan?

Water withdrawals can lead to wells, springs, and wetlands running dry, lake levels dropping, and reducing stream flow with great harm to wildlife. Michigan has been tracking water use for high volume hydraulic fracturing since 2008. The EGLE has a Tracking Table that shows approximate groundwater volumes withdrawn for fracking completions.

How many hydraulically fractured water samples in the Marcellus Shale?

This national spatial and temporal analysis of data on nearly 1 million hydraulically fracture Water samples from 50 domestic wells located 1 km (distal) from shale-gas wells in upland areas of the Marcellus Shale region were analyzed for chemical, isotopic, and groundwater-age tracers.

What is the environmental impact of hydraulic fracturing?

Hydraulic fracturing, commonly known as fracking, is the process of injecting water, sand, and/or chemicals into a well to break up underground bedrock to free up oil or gas reserves. The USGS monitors the environmental impact of this practice across the country, from potential earthquakes to degraded groundwater quality.

What are the stages of the hydraulic fracturing water cycle?

The stages and activities of the hydraulic fracturing water cycle include: Read the executive summary. Stage 1: Water Acquisition. The withdrawal of groundwater or surface water to make hydraulic fracturing fluids. Stage 2: Chemical Mixing. The mixing of a base fluid, proppant, and additives at the well site to create hydraulic fracturing fluids.
