Wellhead Protection Program
The Wellhead Protection Program in the 1986 amendments to the Safe Drinking Water Act requires states to protect underground sources of drinking water from contaminants that may adversely affect human health. More than one-third of the people in the United States depend on groundwater for drinking water. However, residential, municipal, commercial, industrial, and agricultural activities can all contaminate groundwater. In the event of contamination, a community's drinking water supply can develop poor quality or be lost altogether. Groundwater contamination might not be detected for a long period of time and health problems can occur from drinking contaminated water. Cleanup of a contaminated underground source of drinking water may be impossible or so difficult it costs thousands or millions of dollars. The U.S. Congress requiring Wellhead Protection Programs b42 U.S.C. § 300h–7in the Safe Drinking Water Act applied the concept that it is better to prevent groundwater contaminat ...

Safe Drinking Water Act
The Safe Drinking Water Act (SDWA) is the principal federal law in the United States intended to ensure safe drinking water for the public. Pursuant to the act, the Environmental Protection Agency (EPA) is required to set standards for drinking water quality and oversee all states, localities, and water suppliers that implement the standards. The SDWA applies to every public water system (PWS) in the United States. There are currently over 148,000 public water systems providing water to almost all Americans at some time in their lives. The Act does not cover private wells (in 2020, 13% of US households were served by private wells). The SDWA does not apply to bottled water. Bottled water is regulated by the Food and Drug Administration (FDA), under the Federal Food, Drug, and Cosmetic Act. National Primary Drinking Water Regulations The SDWA requires EPA to establish ''National Primary Drinking Water Regulations'' (NPDWRs) for contaminants that may cause adverse public h ...

Capitol City Plume Superfund Site
The Capitol City Plume, which also is referred to as the Capital City Plume, is an area of contaminated groundwater located beneath the western downtown area of Montgomery, Alabama. The contamination was discovered in 1993 by the Alabama Department of Environmental Management (ADEM) which was investigating soil contamination at the Retirement Systems of Alabama Energy Plant in the city. After assessment by the United States Environmental Protection Agency (EPA) it was proposed for inclusion in the National Priorities List The National Priorities List (NPL) is the priority list of hazardous waste sites in the United States eligible for long-term remedial investigation and remedial action (cleanup) financed under the federal Superfund program. Environmental Protec ... (NPL) in May 2000. The City of Montgomery managed to keep the site off of the NPL, eliminating the possibility that it could be labeled a superfund site, by taking fiscal responsibility for the site and its ...

Groundwater Recharge
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and or reclaimed water is routed to the subsurface. Processes Water is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge may be impeded somewhat by human activities including paving, development, or logging. These activities can result in loss of topsoil resulting in reduced water infiltration, enhanced surface runoff and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater Flow
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Hydrogeology
Hydrogeology (''hydro-'' meaning water, and ''-geology'' meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers). The terms groundwater hydrology, geohydrology, and hydrogeology are often used interchangeably. Hydrogeology is the study of the laws governing the movement of subterranean water, the mechanical, chemical, and thermal interaction of this water with the porous solid, and the transport of energy, chemical constituents, and particulate matter by flow (Domenico and Schwartz, 1998). Groundwater engineering, another name for hydrogeology, is a branch of engineering which is concerned with groundwater movement and design of wells, pumps, and drains. The main concerns in groundwater engineering include groundwater contamination, conservation of supplies, and water quality.Walton, William C. (November 1990). ''Principles of Groundwater Engin ...

Woburn, Massachusetts
Woburn ( ) is a city in Middlesex County, Massachusetts, Middlesex County, Massachusetts, United States. The population was 40,876 at the 2020 census. Woburn is located north of Boston. Woburn uses Massachusetts' mayor-council form of government, in which an elected mayor is the executive and a partly district-based, partly at-large city council is the legislature. It is the only one of Massachusetts' 351 municipalities to refer to members of its City Council as "Aldermen." History Woburn was first settled in 1640 near Horn Pond, a primary source of the Mystic River, and was officially incorporated in 1642. At that time the area included present day towns of Woburn, Winchester, Burlington, and parts of Stoneham, Massachusetts, Stoneham and Wilmington. In 1740 Wilmington, Massachusetts, Wilmington separated from Woburn. In 1799 Burlington, Massachusetts, Burlington separated from Woburn; in 1850 Winchester, Massachusetts, Winchester did so, too.

Rocky Mountain Arsenal
The Rocky Mountain Arsenal was a United States chemical weapons manufacturing center located in the Denver Metropolitan Area in Commerce City, Colorado. The site was completed December 1942, operated by the United States Army throughout the later 20th century and was controversial among local residents until its closure in 1992. Much of the site is now protected as the Rocky Mountain Arsenal National Wildlife Refuge. History After the attack on Pearl Harbor and the United States entered World War II, the U.S. Army began looking for land to create a chemical manufacturing center. Located just north of Denver, in Commerce City and close to the Stapleton Airport, the U.S. Army purchased . The location was ideal, not only because of the proximity to the airport, but because of the geographic features of the site, it was less likely to be attacked. The Rocky Mountain Arsenal manufactured chemical weapons including mustard gas, napalm, white phosphorus, lewisite, chlorine gas, and sar ...

MTBE Controversy
Methyl tert-butyl ether (MTBE) is a gasoline additive that replaced tetraethyllead. MTBE is an oxygenate and raises gasoline's octane number. Its use declined in the United States in response to environmental and health concerns. It has polluted groundwater due to MTBE-containing gasoline being spilled or leaked at gas stations. MTBE spreads more easily underground than other gasoline components due to its higher solubility in water. Cost estimates for removing MTBE from groundwater and contaminated soil range from $1 billion to $30 billion, including removing the compound from aquifers and municipal water supplies, and replacing leaky underground oil tanks. Who will pay for remediation is controversial. In one case, the cost to oil companies to clean up the MTBE in wells belonging to the city of Santa Monica, California is estimated to exceed $200 million. Some U.S. states banned MTBE in gasoline. California and New York, which together accounted for 40% of U.S. MTBE consumpt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hinkley Groundwater Contamination
From 1952 to 1966, Pacific Gas and Electric Company (PG&E) dumped about 370 million gallons (1,400 million litres) of chromium-tainted wastewater into unlined wastewater spreading ponds around the town of Hinkley, California, located in the Mojave Desert about 120 miles north-northeast of Los Angeles. PG&E used chromium 6, or hexavalent chromium (a cheap and efficient rust suppressor), in its compressor station for natural-gas transmission pipelines. Hexavalent-chromium compounds are genotoxic carcinogens. In 1993, legal clerk Erin Brockovich began an investigation into the health impacts of the contamination. A class-action lawsuit about the contamination was settled in 1996 for $333 million (around $621 million in 2023). In 2008, PG&E settled the last of the cases involved with the Hinkley claims. Since then, the town's population has dwindled to the point that in 2016 ''The New York Times'' described Hinkley as having slowly become a ghost town. History During the early ...
