The atmosphere as a source of volatile organic compounds (VOCs) in shallow groundwater was evaluated over an area in southern New Jersey. Chloroform, methyl tertbutyl ether (MTBE), 1,1,1‐trichloroethane, tetrachloroethylene (PCE), and carbon disulfide (not a VOC) were detected frequently at low‐level concentrations in a network of 78 shallow wells in the surficial .

Arsenic is a human carcinogen that occurs ubiquitously in soil and water. Based on epidemiological studies, a benchmark dose (lower/higher bound estimate) between and 8 μg/kg bw/day was estimated to cause a 1 % increased risk of lung, skin and bladder cancer.

Update to the National Program Guidance for the Office of Water, U.S. Environmental Protection Agency, FY With this article, we develop the Drinking Water Disparities Framework to explain environmental injustice in the context of drinking water in the United States.
The framework builds on the social epidemiology and environmental justice literatures, and is populated with 5 years of field data (–) from California’s San Joaquin by: STEROID HORMONES. The occurrence and fate of steroid hormones in agricultural environments continues to be of interest.

The amendments to the Safe Drinking Water Act (SDWA) require that the United States Environmental Protection Agency (EPA or the agency) establish criteria for a program to monitor unregulated contaminants and publish a list of up to 30 contaminants to be.
Muddy or turbid water: Unlike chemical contaminants, we can see SS. If water is cloudy or muddy, there is an excess of some sort of material suspended in the water (see Figure 10). If water is tinged with green, golden or brown coloration, there may be phytoplankton that may act as particles similar to clay.
FOREWORD The Safe Drinking Water Act (SDWA), as amended inrequires the Administrator of the U.S. Environmental Protection Agency (EPA) to establish a list of unregulated microbiological and chemical contaminants that are known or anticipated to occur in public water systems and that may need to be controlled with a national primary drinking water regulation.
This new document provides updated scientific data and information related to the health effects of uranium, and still focuses on kidney effects in male rats. It outlines analytical methods and treatment technologies available at the municipal and residential scales. It proposes to reaffirm the MAC of mg/L (20 µg/L) for total uranium in drinking water.
In the race to enhance agricultural productivity, irrigation will become more dependent on poorly characterized and virtually unmonitored sources of water. Increased use of irrigation water has led to impaired water and soil quality in many areas. Historically, soil salinization and reduced crop productivity have been the primary focus of irrigation water by: 2.
It is regulated in California in drinking water and soil. The U.S. EPA has approved: Ion chromatography analysis of Cr (VI) in Method for drinking water; Ion chromatography analysis of Cr (VI) in ground water and industrial wastewater in SW Method ; The EPA SW Method A for extraction of Cr (VI) from soil.
Elevated levels of arsenic in drinking water are found in several parts of Asia. Prolonged intakes of even low concentrations typically have serious health effects. This research paper integrates results of various studies on arsenic contamination of ground, surface, waste and drinking water in north-central Mongolia.
Samples were analyzed with the ARSOlux biosensor and the Arsenator field Cited by: 1. Introduction. Groundwater is an important natural resource that supports socioeconomic development and maintains ecological balance in modern societies .It provides 36% of drinking water, 42% of water for agriculture, and 24% of water for industry [2,3].The quality of groundwater resources globally is threatened by the natural geochemical background and anthropogenic pollution [4,5].Author: Qibin Chen, Guilian Fan, Wei Na, Jiming Liu, Jianguo Cui, Hongyan Li.
Concern over the occurrence of arsenic (As) in drinking water has a long history. The effects of chronic As exposure have been well documented and have provided the basis for regulating As concentrations in drinking water (NRC ; U.S.
EPA ).In the United States, a limit of 50 μg / L was first set for As in and is still the standard in some countries today (Mondal et al. The line chart in Fig. 1 shows the annual publication output performance of the six most productive countries.
Though at a low publishing level, the USA played a role of pioneer in this area over the first decade generally. After that, the publication number in China experienced and kept a robust rise in the following decade and took the leading position with by: 4.
Volatile organic compounds are ground‐water contaminants of concern because of large environmental releases, human toxicity, and a tendency for some compounds to persist in and migrate with ground water to drinking‐water supply wells.
In general, VOCs have high vapor pressures, low‐to‐medium water solubilities, and low molecular by: Definition: Infection or intoxication caused by the transfer of microbial or chemical contaminants (substances that spoil or infect) from food or drinking water to a human. In most cases, the contaminants are bacteria, parasites, or viruses.

In this letter report, the committee presents the details of its evaluation of the Agency for Toxic Substances and Disease Registry (ATSDR) report drafts, of ATSDR’s response to review, and of the concerns of the Office of the Director of ATSDR and the Office.
For this bibliometric analysis, the online search within Web of Science was carried out by the insertion of “drinking water” and “arsenic” as keywords in the topic field of the search-engine in order to compile a complete bibliography with all the articles related to the research on arsenic in drinking water published during the period Cited by: Revisions to the Unregulated Contaminant Monitoring Regulation (UCMR 3) for Public Water Systems, .
1,2-Dichloroethane (1,2-DCA) and 1,2-dibromoethane (ethylene dibromide [EDB]) contaminate groundwater at many hazardous waste sites. The objectives of this study were to measure yields, maximum specific growth rates (μ̂), and half-saturation coefficients (KS) in enrichment cultures that use 1,2-DCA and EDB as terminal electron acceptors and lactate as the electron donor and to Cited by:
