  • Studies reveal why drinking water wells are vulnerable to contamination

    New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States receive ...

  • Private U.S. Drinking Water Wells Contaminated with Arsenic and Other Harmful Elements

    Geologists with the U.S. Geological Survey (USGS) recently discovered that 13 percent of untreated drinking water contains at least one potentially dangerous element at a concentration exceeding federal regulations or guidelines, reports Scientific American. Researchers checked private wells for 24 trace elements and found that they taint more wells than other pollutants, such as pesticides and ...

  • Fracking: leaking wells cause gas-contaminated groundwater

    Contamination of drinking water in areas close to several fracking sites in the Marcellus and Barnett Shales, USA, is caused by structural problems leading to wells leaking natural gas into aquifers, a new study suggests. The researchers measured trace amounts of chemicals, called noble gases, which formed signatures of the sources of gas contamination in over 130 samples. These findings suggest ...

  • Leaky wells, not fracking, taint water

    The drilling procedure called fracking didn't cause much-publicized cases of tainted groundwater in areas of Pennsylvania and Texas, a new study finds. Instead, it blames the contamination on problems in pipes and seals in natural gas wells. After looking at dozens of cases of suspected contamination, the scientists focused on eight hydraulically fractured wells in those states, where they ...

  • Cholera outbreaks blamed on contaminated water

    Recurrent outbreaks of cholera in the western province of Nyanza are caused by widespread water contamination, including seepage from latrines, health officials said. 'The major contributor to the recent outbreaks in the area was unsafe water,' Shahnaaz Sharif, the senior deputy director of medical services in Kenya's health ministry, said. 'In Kisumu, many wells are built near the latrine; ...

  • Benzene Levels Exceed Limits in 12 of the 17 Wells Contaminated in Jackson

    After a massive gas spill in Jackson, WI, 17 private wells have been contaminated with gasoline. Levels of benzene, a gasoline component, in 12 of the wells were found to be higher than the safe drinking water standard of 5 parts per billion established by the federal government. The pipeline break that occurred on July 17th spilled an estimated 54,600 gallons of gasoline. An excavation of ...

  • Testing the water is important for household well owners

    The National Ground Water Association recommends household well owners test their water at least annually for bacteria, nitrate, and any contaminants of local concern. More frequent testing should be considered if: There is a change in the taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap, inundation by floodwaters, or a new contamination ...

  • 5 Reasons to Test Your Well Water

    A lot of us know that we should test our water when we notice a problem with it. Three of the most common problems are when the water gives off a bad smell, is discolored or leaves behind stains. However do you realize that some problems you may be facing such as gastrointestinal upsets, dry skin, or even hardness may be a sign that there is something wrong with your water? Most dangerous ...

  • Regular water testing important for household water well owners

    Started by the National Ground Water Association, the 16th annual National Groundwater Awareness Week takes place March 9-15, 2014. According to NGWA, this is a good time for owners of household water wells, as managers of their own personal drinking water system, to test the water. At a minimum, private well owners should ...

  • Abandoned water wells can present risks

    Household water well owners should act to address any improperly abandoned wells on their property as they can present threats to both people and animals, the National Ground Water Association said today. “Abandoned wells can be a physical danger to people and animals who may fall into them, but an even greater threat may be the pathway that an abandoned well provides for surface ...

  • Household water well inspections important to water quality, health

    National Groundwater Awareness Week, March 10-16, 2013, is a good time to schedule a water well system inspection to assure proper well operation, prolong the well system’s life, and monitor groundwater quality, the National Ground Water Association and its 48 affiliated state organizations said today. “Water wells are expertly engineered systems that, like a car, ...

  • Shale gas extraction linked to water contamination

    A new study suggests shale gas extraction leads to methane contamination of underground water sources and calls for thorough surveys of methane levels at extraction sites. The study presents a timely insight into a relatively under-researched area of science that will help support decisions on the future of shale gas exploration. Shale gas, or natural gas extracted from sedimentary rocks ...

  • Drinking water of 41m Americans contaminated with pharmaceuticals

    An investigation by the Associated Press (AP) has revealed that the drinking water of at least 41 million people in the United States is contaminated with pharmaceutical drugs. It has long been known that drugs are not wholly absorbed or broken down by the human body. Significant amounts of any medication taken eventually pass out of the body, primarily through the urine. 'People think that if ...

  • Water well owners should check water periodically for bacteria, nitrate

    Bacteria and nitrate are widespread in the environment, so every household water well owner should regularly test their water to make sure no health risk exists, the National Ground Water Association recommended today.
