The study area within the Potomac River basin of eastern North America. Open circles show sample site locations on streams within the C&O Canal National Historical Park. Shaded areas show physiographic regions within Maryland from west to east as the Ridge and Valley, Blue Ridge, and Piedmont, and the stippled areas show regions of karst geology.

Equipment used for water-quality sampling needs thoroughly cleaned to remove lingering contaminants or sediment. In this photo, a peristaltic pump is used to flush three different solutions (liquid detergent, tap water, and deionized water) through the tubing used to collect raw-water samples from the public water supply systems.

Collecting raw-water samples from a public water supply system pump house. Water is drawn into a sampling chamber (left) to prevent external contamination of the water. A sonde connected to a handheld display (right) records ancillary parameters like pH, temperature, and dissolved oxygen.

This scenic view of Howards Creek was observed in White Sulphur Springs, a city in Greenbriar County in southeastern West Virginia.

The Chesapeake Bay watershed, or draingage basin, encompasses six states - New York, Pennsylvania, West Virginia, Maryland, Delaware, Virginia, and the District of Columbia. A drainage basin is a giant system of creeks, streams, and rivers that all flow into a common outlet, which in this case is the Chesapeake Bay.

Histology laboratory with microtoming area to the left.  Microtoming is when tissues are cut into very thin slices and placed on glass slides prior to being stained and coveslipped.  In the center is the incubator where slides are dried when needed.
