USGS scientists measured the concentrations of select endocrine disrupting chemicals (EDCs) in Spirit Creek, Georgia, as part of an assessment of the effects of the closure of a wastewater treatment plant. Sprit Creek is typical of a stream in coastal environments.

Epic flooding conditions at Peachtree Creek, Atlanta, Ga., September 2009.
Many days of continuous heavy rain in mid-September have resulted in flooding in many parts of Georgia, especially in north Georgia and the Atlanta region. These rains have been producing streamflows of record proportions.

Volunteer picking up trash along Walnut Creek Tributary, Raleigh, North Carolina. Litter from upstream often gets caught in the wetlands along Walnut Creek, degrading an important habitat refuge in the urban watershed.

Noses Creek at Powder Springs Road, Georgia. Part of the USGS safety protocol is to wear a PFD (personal flotation device) around any surface water. This scientist may not look like he has one on, but he does--it is under his rain coat. This DH-81 sampler is used to sample flood water for suspended-sediment concentrations and water quality.

A USGS scientist about the collect a water sample with a DH-95 sampler (the white torpedo looking device). After sampling, another scientist takes the bottle of water and pours it into the churn. Having another scientist do this prevents contamination of the sample.

Pew Creek below Johnson Road, Lawrenceville, Ga. The metal structure is a "V" weir. A sediment dam was built on either side of it to force the water through the weir. Scientists can calculate gallons per minute flow in the stream by timing how long the flow took to fill a bucket.

USGS test well 10 34h363 in the East River, Brunswick, Ga. The U.S. Geological Survey drilled this test well in the early 1970's and at the time it was on the edge of the marsh at Andrews Island. It is now only accessible by boat or canoe at high tide. Despite being surrounded by saltwater the artesian well flows very fresh water from the Upper Floridan Aquifer.

Installing a water-level monitoring gage, Coosawattee River, Georgia. Two USGS workers installing a "stilling well"s, which is a major component of most systems used to monitor stream stage (gage height). The pipe is placed vertically into the stream and the level of the water in the pipe is continuously monitored and transmitted to USGS water-science offices.
