Janet M Carter
I am a Bureau Approving Official (BAO) in the Office of Science Quality and Integrity (OSQI) within the Office of the Director.
I began working for the U.S. Geological Survey in 1990 as a student hydrologist. In 1994, I became a hydrologist with the South Dakota Water Science Center working in the Huron and Rapid City offices performing research on water quality and groundwater. I worked on many studies in South Dakota and several regional, national, and international studies. I also served as the report specialist for the South Dakota Water Science Center and other Centers within the USGS. In 2016, I became the Deputy Director for Studies for the then newly formed Dakota Water Science Center. In April 2019, I transitioned to a Bureau Approving Official with the Office of Science Quality and Integrity. I have authored or co-authored more than 50 scientific publications and thoroughly enjoyed working on all of them.

Pesticide concentrations in wetlands on the Lake Traverse Indian Reservation, South and North Dakota, July 2015
During July 2015, water samples were collected from 18 wetlands on the Lake Traverse Indian Reservation in northeastern South Dakota and southeastern North Dakota and analyzed for physical properties and 54 pesticides. This study by the U.S. Geological Survey in cooperation with the Sisseton-Wahpeton Oyate was designed to provide an update on pesticide concentrations of the same 18 wetlands that wAuthorsJanet M. Carter, Ryan F. ThompsonPrioritization of constituents for national- and regional-scale ambient monitoring of water and sediment in the United States
A total of 2,541 constituents were evaluated and prioritized for national- and regional-scale ambient monitoring of water and sediment in the United States. This prioritization was done by the U.S. Geological Survey (USGS) in preparation for the upcoming third decade (Cycle 3; 2013–23) of the National Water-Quality Assessment (NAWQA) Program. This report provides the methods used to prioritize theAuthorsLisa D. Olsen, Joshua F. Valder, Janet M. Carter, John S. ZogorskiFactors associated with sources, transport, and fate of chloroform and three other trihalomethanes in untreated groundwater used for drinking water
Multiple lines of evidence for indicating factors associated with the sources, transport, and fate of chloroform and three other trihalomethanes (THMs) in untreated groundwater were revealed by evaluating low-level analytical results and logistic regression results for THMs. Samples of untreated groundwater from wells used for drinking water were collected from 1996-2007 from 2492 wells across theAuthorsJanet M.

Release 4.0 of the U.S. Geological Survey S-PLUS library supercedes release 2.1. It comprises functions, dialogs, and datasets used in the U.S. Geological Survey for the analysis of water-resources data. This version does not contain ESTREND, which was in version 2.1. See Release 2.1 for information and access to that version. This library requires Release 8.1 or later of S-PLUS for Windows. S-PLAuthorsDavid L. Lorenz, Elizabeth A. Ahearn, Janet M.

WilliamsonConcentration data for anthropogenic organic compounds in groundwater, surface water, and finished water of selected community water systems in the United States, 2002-10
The National Water-Quality Assessment Program of the U.S. Geological Survey began implementing Source Water-Quality Assessments (SWQAs) in 2001 that focus on characterizing the quality of source water and finished water of aquifers and major rivers used by some of the larger community water systems in the United States. As used in SWQA studies, source water is the raw (ambient) water collected atAuthorsJanet M. Carter, James A. Kingsbury, Jessica A. Hopple, Gregory C. DelzerThunderstorms and flooding of August 17, 2007, with a context provided by a history of other large storm and flood events in the Black Hills area of South Dakota
The Black Hills area of western South Dakota has a history of damaging flash floods that have resulted primarily from exceptionally strong rain-producing thunderstorms. The best known example is the catastrophic storm system of June 9-10, 1972, which caused severe flooding in several major drainages near Rapid City and resulted in 238 deaths. More recently, severe thunderstorms caused flash floodiAuthorsDaniel G. Driscoll, Matthew J. Bunkers, Janet M. Carter, John F. Stamm, Joyce E. WilliamsonEstimated use of water in South Dakota, 2005
During 2005, withdrawals from ground-water and surface-water sources in South Dakota for the eight categories of offstream use totaled about 500 million gallons per day (Mgal/d). Of total withdrawals, about 271 Mgal/d was withdrawn from ground water and about 230 Mgal/d was withdrawn from surface water. The largest use of water in South Dakota during 2005 was irrigation, which accounted for aboutAuthorsJanet M. Carter, Kathleen M. NeitzertOccurrence of volatile organic compounds in aquifers of the United States
Samples of ambient ground water were collected during 1985-2002 from 3,498 wells in 98 aquifer studies throughout the United States. None of the sampled wells were selected because of prior knowledge of nearby contamination. Most of these samples were analyzed for 55 volatile organic compounds (VOCs) to characterize their national occurrence. Volatile organic compounds were found in samples collecAuthorsJanet M. Carter, W.W. Lapham, J.S. ZogorskiSummary of selected U.S. Geological survey data on domestic well water quality for the Centers for Disease Control's National Environmental Public Health Tracking Program
About 10 to 30 percent of the population in most States uses domestic (private) water supply. In many States, the total number of people served by domestic supplies can be in the millions. The water quality of domestic supplies is inconsistently regulated and generally not well characterized. The U.S. Geological Survey (USGS) has two water-quality data sets in the National Water Information SystemAuthorsRoy C. Bartholomay, Janet M. Carter, Sharon L. Qi, Paul J. Squillace, Gary L.

This national assessment of 55 volatile organic compounds (VOCs) in ground water gives emphasis to the occurrence of VOCs in aquifers that are used as an important supply of drinking water. In contrast to the monitoring of VOC contamination of ground water at point-source release sites, such as landfills and leaking underground storage tanks (LUSTs), our investigations of aquifers are designed asAuthorsJohn S.

Results from two national surveys indicate that the gasoline oxygenate methyl tertiary butyl ether (MTBE) is one of the most frequently detected volatile organic compounds in source waters used by community water systems in the United States. Three other ether oxygenates were detected infrequently but almost always co-occurred with MTBE. A random sampling of source waters across the United StatesAuthorsJanet M. Carter, Stephen J.
