The labs at the MD-DE-DC WSC are clean, well-stocked, and appointed with modern equipment and a highly talented staff. The three labs analyze samples, conduct controlled-environment chemical tests with GCMS in the Water Qualty lab. Scientists and technicians work with core samples and analyze soils in the Sediment Lab.
Our labs assure reliability, reproducibility, and high quality of its data and information through adherence to USGS Fundamental Science Practices for publications. The use of comprehensive internal and external QA/QC processes to monitor method and analyst performance insure that our labs meet their commitment to publish high quality data of known and documented quality. External, independent oversight is provided by the USGS Branch of Quality Services as our labs are inspected by USGS qualified safety professionals.
There will be a lot more information specific to the labs at the MD-DE-DC WSC coming to this site very soon!

Below are FAQ associated with this project.
How frequently are volatile organic compounds (VOCs) detected in groundwater?
Volatile organic compounds (VOCs), which are widely used in the manufacture of many products including refrigerants, plastics, adhesives, paints, and petroleum products, have been detected in about one-third of the wells sampled by the National Water-Quality Assessment (NAWQA) Program of the USGS. Chloroform and other trihalomethanes, the most commonly detected compounds, were found in about 9...
Does the use of pesticides affect our Nation's water quality?
Pesticide use in the United States has increased because not only must we supply our exploding population with food, but crops and food are also grown for export to other countries. The United States has become the largest producer of food products in the world, partly owing to our use of modern chemicals (pesticides) to control the insects, weeds, and other organisms that attack food crops. But...

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Processing, taxonomy, and quality control of benthic macroinvertebrate samples
Qualitative and quantitative methods to process benthic macroinvertebrate (BMI) samples have been developed and tested by the U.S. Geological Survey?s National Water Quality Laboratory Biological Group. The qualitative processing method is based on visually sorting a sample for up to 2 hours. Sorting focuses on attaining organisms that are likely to result in taxonomic identifications toAnalytical properties of some commercially available nitrate reductase enzymes evaluated as replacements for cadmium in automated, semiautomated, and manual colorimetric methods for determination of nitrate plus nitrite in water
A multiyear research effort at the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) evaluated several commercially available nitrate reductase (NaR) enzymes as replacements for toxic cadmium in longstanding automated colorimetric air-segmented continuous-flow analyzer (CFA) methods for determining nitrate plus nitrite (NOx) in water. This research culminated in USGS approvedInterpreting and Reporting Radiological Water-Quality Data
This document provides information to U.S. Geological Survey (USGS) Water Science Centers on interpreting and reporting radiological results for samples of environmental matrices, most notably water. The information provided is intended to be broadly useful throughout the United States, but it is recommended that scientists who work at sites containing radioactive hazardous wastes need to consultDetermination of human-health pharmaceuticals in filtered water by chemically modified styrene-divinylbenzene resin-based solid-phase extraction and high-performance liquid chromatography/Mass Spectrometry
In 1999, the Methods Research and Development Program of the U.S. Geological Survey National Water Quality Laboratory began the process of developing a method designed to identify and quantify human-health pharmaceuticals in four filtered water-sample types: reagent water, ground water, surface water minimally affected by human contributions, and surface water that contains a substantial fractionMethods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of whole-water recoverable arsenic, boron, and vanadium using inductively coupled plasma-mass spectrometry
Analysis of in-bottle digestate by using the inductively coupled plasma?mass spectrometric (ICP?MS) method has been expanded to include arsenic, boron, and vanadium. Whole-water samples are digested by using either the hydrochloric acid in-bottle digestion procedure or the nitric acid in-bottle digestion procedure. When the hydrochloric acid in-bottle digestion procedure is used, chloride - FAQ
