The vast amount of waste water produced by fracking can contaminate rivers, lakes and other waterways with radioactive material and hormone-affecting chemicals, according to new research.
The study tested sediments and groundwater downstream of a treatment plant in Pennsylvania that was designed to make the water used as part of the fracking process fit for release into the environment.
Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale.
Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
Excerpted from Concepts and Challenges of Life Science From Pearson's Concepts and Challenges Immigration dating Science. Integrate dzting science, archeology, and physical science as you review how the half-life of radioactive elements is used to date fossils and rocks. In this science printable, students will review how the half-life of radioactive elements can be used to determine a rock's absolute age. Use the diagrams and fossils shown in this printable to make inferences about the relative age of rock layers.
