Most wells experience some type of operational problem during the normal process of aging. The rate at which a well will experience such problems can be influenced by many factors, including water chemistry, aquifer characteristics, operational schedules and well construction details, just to name a few.
There are many types of wells across the globe, including water supply, injection, aquifer storage recovery, extraction, monitoring and dewatering, and most deteriorate as they age.
Time-based approach to effective well maintenance
Approximately 30 million Americans get their drinking water from private household wells. Protection of private wells does not fall under the U.S. Environmental Protection Agency’s (EPA) Safe Drinking Water Act, so well owners must take it upon themselves to ensure their water quality. To keep water clean and pure and the well operating at peak performance, regular water testing is an important maintenance tool.
Selecting the right combination of tests for water wells
It’s been well established that drought, water scarcity and sustainability are the most important issues facing the water industry. In the coming decades, these factors will not just shape the way we use and value water, they also will drive technological innovation and the laws and regulations surrounding water.
Groundwater cleanup near the New Cassel industrial area expected to cost $22.9 million
The U.S. Environmental Protection Agency (EPA) has finalized its plan to clean up a portion of contaminated groundwater beneath the New Cassel/Hicksville Ground Water Contamination Superfund site in the towns of Hempstead, North Hempstead and Oyster Bay in Nassau County, N.Y.
Performance tested by the U.S. EPA, the Multi-Barrier System provides > 4-log reduction of Cryptosporidium and viruses, meeting disinfection requirements for the Ground Water Rule, Groundwater Under the Direct Influence of surface water and Long Term 2 Enhanced Surface Water Treatment Rule. It includes three treatment stages: sediment filtration, charged membrane filter and UV. It offers flow rates from 8 to 480 gpm, with capabilities for monitoring flow, filter life and UV status to provide fail-safe disinfection protection.
New book highlights the efforts of Maine citizens to prevent a corporation from extracting groundwater
In From Groundwater to Grass Roots, author Walter Baily chronicles the struggle of residents in the rural Maine towns of Newfield and Shapleigh to prevent an international corporation from extracting groundwater. This book highlights residents’ actions and developing knowledge as they advocate for protecting groundwater beneath their homes and communities. The issue was not only preservation of an aquifer, but the principle that a resource fundamental to life should not become a commodity for private profit.
With flow rates ranging from 30 to 60 liter per minute, UVDynamics Mini-Rack Systems incorporate up to three filter housings and an ultraviolet disinfection system into one clean-looking, integrated product. An optional floor stand simplifies installation where wall mounting is impractical. UVDynamics Mini-Rack systems speed installation, are easy to service and provide lasting value.
Awards will be presented this December during the NGWA Groundwater Expo and Annual Meeting
The National Ground Water Assn. congratulated the recipients of its annual Awards of Excellence, Outstanding Groundwater Project Awards and Divisional Awards, which will be presented this December during the NGWA Groundwater Expo and Annual Meeting in Nashville, Tenn.
The town of Newport Center, Vt., is a small community of approximately 1,500 residents located just south of the U.S.-Canada border. A combination of drought and increased water use required the drilling of a new well for the community to supplement the two wells already in service. Water quality testing of the new well found arsenic levels at 20 ppb, well above the drinking water standard set by the U.S. Environmental Protection Agency (EPA) and the state of Vermont of 10 ppb.
Arsenic removal system helps New England town meet standards
The water treatment industry seems to be full of new ideas about how to treat water in innovative ways. NPR reported that UNICEF is promoting a machine developed by Sweden’s Royal Institute of Technology and HVR that turns sweat into drinking water by filtering the drippings squeezed from clothes. In answer to the Bill and Melinda Gates Foundation’s “Reinvent the Toilet” competition, researchers at Duke have developed a new toilet, complete with a self-contained waste recycling system, that transforms wastewater into drinking water.
