Water-Quality Sampling
Detailed Description
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.
