Community Home Contact Us Visit Us Brookhaven Lab Home Search Cleanup Home Groundwater DOE, BNL, elected officials, and community leaders mark the opening of the first off-site groundwater treatment system. Chemical Groundwater Contamination The most common chemical pollutants found in the groundwater are called volatile organic compounds (VOCs). These compounds were, and still are, used in a wide variety of consumer products and industrial processes. At BNL, one common VOC called carbon tetrachloride, for example, was found in pesticides, in cleaning fluids and degreasing agents, in fire extinguishers, and in spot removers; use of VOCs at the Lab dates back to the 1940s. The environmental impact of these materials was not well understood during the early years of their use, and what were considered acceptable disposal methods for these chemicals at that time are no longer utilized. In some instances, these chemicals were spilled onto the ground or poured into drains. One of the drill rigs used to install off-site groundwater treatment wells These releases to the environment allowed the VOCs to eventually make their way into the groundwater. Once the Lab discovered that these compounds had entered the groundwater and were moving off the site, more than 3,000 temporary and permanent on- and off- site groundwater monitoring wells were installed between 1990 and 2005 to develop a detailed picture of the nature and extent of contamination.

To find out if you need an environmental permit and for details of how to apply, please visit the following web page: Environmental permitting - groundwater How we manage groundwater Our water resources are not just our rivers, lakes and reservoirs. Our largest resources are underground. The Environment Agency has a duty to manage the use of this groundwater, balancing the need to supply consumers with the need to preserve the environment, protect it from pollution and over-abstraction and where it is already polluted to clean it up.

Arsenic in Drinking Water and Groundwater by: Mr. Brian Oram, PG B.F. Environmental Consultants Inc. Residential Water Supply and Homeowner Drinking Water Testing Evaluation Program Click on Map to See Full Scale - Arsenic concentrations in Ground Water of the United States. (Source: USGS) What is arsenic? Arsenic is a semi-metal, a member of the nitrogen family. It occurs naturally in the earth and in the seas. It is odorless and tasteless. Arsenic is an element (As) that occurs in the earth’s crust-rock, soil, all natural sources of exposure, or can be traced to deep water brines used to produce oil and natural gas. Consumption of food and water are the major sources of arsenic exposure for the majority of US citizens. People may also be exposed from industrial sources, as arsenic is used in semiconductor manufacturing, petroleum refining, wood preservatives, animal feed additives, and herbicides. Arsenic can combine with other elements to form inorganic and organic arsenicals. In general, inorganic derivatives are regarded as more toxic than the organic forms. While food contains both inorganic and organic arsenicals, primarily inorganic forms are present in water. Exposure to arsenic at high levels poses serious health effects as it is a known human carcinogen. In addition, it has been reported to affect the vascular system in humans and has been associated with the development of diabetes. As compared to the Western part of the United States, it is relatively rare contaminant in Pennsylvania groundwater supplies. A recent survey by the U.S Geological Survey (USGS) found that arsenic exceeded 5 ppb in 5% of wells in Pennsylvania.
