Capillary Action and Water

Plants and trees couldn't thrive without capillary action. Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it's way all the way up to the branches and leaves. Read on to learn more about how this movement of water takes place.

Biological Oxygen Demand (BOD) and Water

You don't often think that water bodies contain oxygen, but water does contain a small amount of dissolved oxygen. A small amount, but it is essential for life in the water. Biological oxygen demand (BOD) generally represents how much oxygen is needed to break down organic matter in water.

Environmental DNA (eDNA)

Environmental DNA (eDNA) is organismal DNA that can be found in the environment. Environmental DNA originates from cellular material shed by organisms (via skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods. Such methodology is important for the early detection of invasive species as well as the detection of rare and...

Bacteria and E. Coli in Water

Water, like everything else on Earth, including you, is full of bacteria. Some bacteria are beneficial and some are not. Escherichia coli (E. coli) bacteria, found in the digestive tract of animals, can get into the environment, and if contacted by people, can cause health problems and sickness. Find out the details here.

Aqueducts Move Water in the Past and Today

An aqueduct has been and continues to be an imporant way to get water from one place to another. Be it 2,000 years ago in ancient Rome, Italy or today in California, aqueducts were and are essential to get water from a place where it exists in ample supply to where it is scarce. Find out how these "ancient marvels" work.

Gold King Mine release (2015): USGS water-quality data and activities

On August 5, 2015, U.S. EPA was conducting an investigation of the Gold King Mine near Silverton, Colorado. While excavating as part of the investigation, water began leaking from the mine tunnel, and about three million gallons of water and sediment were released into Cement Creek, a tributary of the Animas River. The USGS provided pre- and post-release water-quality and streamflow data from...

Fiber-Optic Distributed Temperature Sensing in Waquoit Bay, Massachusetts

In 2006 the USGS Office of Groundwater, Branch of Geophysics (OGW BG) conducted a technology demonstration and evaluation project in Waquoit Bay, East Falmouth, Massachusetts, to evaluate the use of fiber-optic distributed temperature sensing (FO-DTS). In this project, the USGS used FO-DTS to investigate aquifer-estuary interaction by monitoring submarine groundwater discharge in Waquoit Bay....
