At face value, well drilling projects sound as simple as showing up and digging a deep hole in the ground. But it’s important to learn more about how to drill a water well because it isn’t that straightforward. Preparing for a drilling project is more than just setting up the rig. In fact, drill site preparation starts before you arrive at the jobsite and details adjust throughout the ...
The goal of water well drilling is to make a borehole that will create a long-lasting well. Without the proper support, the borehole can collapse in on itself. Here are a few things to keep an eye out for during the drilling process to ensure your borehole has the best chance of ...
Drinking water companies in the Netherlands do special projects worldwide to improve the quality of installations but also support the local engineering. In Kabatini, Kenya, a well field with eight boreholes, nearly all with high maintenance cost, needed to be analyzed for replacement with high efficiency pumps. ...

Motivation Vista Clara NMR Geophysical Equipment helps clients image the subsurface to accurately define hydrogeologic properties including porosity, pore size, mobile and bound water content, permeability, and transmissivity. We offer equipment for sale or rent, as well as, professional consulting services to our ...
Farmers may want to reduce salinity of their wells for irrigation, and they typically use conventional reverse osmosis and ion exchange, but brine production, fouling of membranes, lack of adequate boron reduction, and high cost-of-application continue to hinder the use of treatment technology for well water meeting suitable quality for agricultural use. ...
It also is the least expensive way to help you with many health and growth factors. Start at the source, your well/borehole, dugout (big body of water in a hole with a liner), holding tanks etc. ...
Sensors are the backbone of any water quality monitoring system since they determine accuracy and reliability. As such, it is best to start with picking the sensor(s) when designing a new system for applications such as pollution control, saltwater ingression studies, aquaculture, process control, ...
The miniDOT’s size and shape allow for many different deployment applications including underwater caves, boreholes and wells. Batteries Two AA batteries make the laborious and time-consuming task of shipping your logger back to the manufacturer to replace semi-permanent batteries a thing of the past. ...
Water demand has increased in tandem with the growth of industry, agriculture, and population. Around 60% of the world is now experiencing a freshwater shortage (Zektser I, S., and Everett, L.G., 2000). Recent heatwaves and lack of rainfall have raised concern about the UK’s water resources. Together, these two factors reduce river flow, deplete reservoir stocks, and increase water demand. ...
By using nested wells—one monitoring location with one large borehole that holds multiple well casings, each with screen intervals at distinct depths to target specific aquifers—WRD has been able to collect a wealth of data from a manageable number of sites. ...
The Problem In the area around a refinery’s facilities the groundwater was suspected of being contaminated by hydrocarbons. Test borings in the refinery area confirmed the contamination by waste oil that had percolated through the ground, and that had left a layer of waste oil on the surface of the groundwater. The local authorities engage a consulting company, and asked that they recommend ...
Underground deep drilling inspection camera for Geological Survey are becoming more frequent. Of course, when it comes to well inspections, we may immediately think of water well borehole inspections that are performed primarily in residential areas. ...
However, collecting a sample from a monitoring borehole that is truly representative of the quality of groundwater in the surrounding aquifer is not as easy as it might seem. The water quality of a groundwater sample collected from a monitoring borehole or well is critically dependent on two factors: 1) The length of the screened interval in the ...
The information gathered is useful in determining the desirability of the identified formations depending on the type of well. The data is also essential in informing the drillers if water from the boreholes should receive additional treatment before it is used commercially. ...
LOCATION Sakhalin Island, Russian Federation PRODUCT Microgrid Controller CUSTOMER VALUE Reliable Control of Isolated Microgrid In the remote oil fields of Sakhalin Island in the Russian Federation, Exxon Neftegaz operates some of the longest well boreholes in the world without the benefit of a utility grid connection. ...
The LIAG staff are very happy to have their new Javelin tools which will allow them to perform NMR measurements in a wide variety of borehole and well sizes, to depths of up to 1200 ...
Synonyms Rainbow Trout Fry Syndrome (RTFS) Bacterial fry anemia Low temperature disease Peduncle disease Saddleback Tail-rot Systemic myxobacteriosis Cause of the Disease Bacterial Coldwater Disease (BCWD) is caused by Flavobacterium psychrophilum, also known as Flexibacter psychrophilus and Cytophaga psychrophila. There may be strain differences among isolates but their importance ...
This well was constructed with a 20 inch borehole and 16 inch well casing and when completed yielded 1,800 gallons of water per minute. In 2003, the well yield had dropped to essentially 0 gallons per minute. They were only able to get enough water to fill the well pipe. ...

Lack of Water Financially Crippling One source of confusion is the term “improved,” which is ambiguous and can refer to a wide diversity of water sources such as public taps, boreholes, and wells. Moreover, even “access” is an ambiguous term. ...
