Radius BZ1 Rental: Easily the best gas monitoring solution for oil & gas well plugging projects - Case Study
The first successful use of a drilling rig on a well drilled especially to produce oil was made in 1859. One estimate suggests that since then, 3.5 million oil and gas wells have been drilled in North America. Because many wells were drilled before well permit regulations were introduced, this number may be even higher, reaching estimates of 4 million. Ideally, when a well reaches the end of ...

Increased information on waterborne outbreaks through efficient notification system enforces actions towards safe drinking water
In 1997, a compulsory notification system for waterborne outbreaks was introduced in Finland. The main aim of this notification is to obtain immediate information on suspected waterborne outbreaks in order to restrict and manage the outbreak promptly. During the past ten years, there have been 67 waterborne outbreaks in Finland, mainly associated with small groundwater supplies or private wells. ...

Arsenic in private drinking water wells: an assessment of jurisdictional regulations and guidelines for risk remediation in North America
Arsenic is a known carcinogen found globally in groundwater supplies due to natural geological occurrence. Levels exceeding the internationally recognized safe drinking water standard of 10 μg/L have been found in private drinking water supplies in many parts of Canada and the United States. Emerging epidemiological evidence confirms groundwater arsenic to be a significant health ...

Groundwater management: a search for better policy combinations
Excessive groundwater pumping is now a global concern. There is no panacea for this problem, which needs to be addressed through continual policy improvements based on case studies. Good examples of the diversity of groundwater management are demonstrated by the Tokyo (Japan) and Orange County Water District (OCWD, California, USA) experiences. In Tokyo, excessive groundwater pumping was ...

Passive seismic HVSR surveying for groundwater exploration at the Chilalo Graphite Project, Tanzania
Summary Passive seismic HVSR surveying is increasingly being used for investigating the thickness of soft sedimentary cover deposits sitting over hard and fresh bedrock, and for direct drill targeting of paleochannels for groundwater and brine resources. A detailed passive seismic HVSR survey was carried out at the Chilalo Graphite Project in SE Tanzania to assist with defining the thickness of ...

Classification of groundwater chemistry in Shimabara, using self-organizing maps
Shimabara City in Nagasaki Prefecture, Japan, is located on a volcanic peninsula that has abundant groundwater. Almost all public water supplies use groundwater in this region. For this reason, understanding groundwater characteristics is a pre-requisite for proper water supply management. Thus, we investigated the groundwater chemistry characteristics in Shimabara by use of self-organizing ...

Brackish Water as a Resource
There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although these definitions ...
