Effects of Borehole Fluid on Standard Penetration Test Results
The standard penetration test (SPT) represents the most widely used in-situ test method for evaluating the liquefaction resistance of saturated soils. Significant progress has been made in recent years in developing correlations between SPT results obtained using different test procedures and equipment in order to develop a higher degree of standardization for SPT testing. One of the heretofore ...

Nitrate pollution in groundwater in two selected areas from Cameroon and Chad in the Lake Chad basin
The shallow aquifer in the Lake Chad basin is highly vulnerable to pollution. Analysis carried out on 316 wells and boreholes have showed a tendency towards an increase of nitrate values, exceeding 50 mg l−1. Nitrate concentrations ranged between about 1 and 300 mg l−1. Large variation in concentration was observed in wells and boreholes that are only short distances apart. High concentrations of ...

What is the purpose of soil boring and borehole logging?
What is the purpose of soil boring? Soil boring is a practice of geotechnical investigations whose purpose is to determine the soils load-bearing capabilities, water table and chemical contamination. Boring is important because (1) it helps to determine the capacity of the soil to provide support to the structures on the surface, (2) it reveals the permeability of the soil to establish if it ...

Coliform status of water bodies from two districts in Ghana, west Africa: implications for rural water resources management
Investigations were conducted on the total and faecal coliform status of streams, hand-dug wells and boreholes highly patronised by communities in the West Akim and Kwaebibirem Districts, Eastern Ghana. Total coliform values obtained range from 60–2,672 cfu, 0–680 cfu and 0–128 cfu for streams, hand-dug wells and boreholes, respectively. Faecal coliform values similarly range from 31–1,988 cfu, ...

Why Bentonite Hurts Well Production: The Case for Biopolymer Drilling Fluid
Bentonite is a naturally-occurring clay material, largely composed of the mineral, sodium mont-morillonite. The dominant property of bentonite is that it swells to many times its dry volume when hydrated by water, forming a viscous fluid with high gel strength. This makes bentonite an excellent product when used as a sealant, for preventing the influx of surface water into a well, sealing ...

Radon-222 from different sources of water and the assessment of health hazard
Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56–98.57, 0.88–25.49, 0.73–1.35 and 0.24–1.03 Bq.L−1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% ...

Impact of intestinal microorganisms and protozoan parasites on drinking water quality in Harare, Zimbabwe
The presence of microorganisms and their potential impacts on drinking water from boreholes, bowsers, lakes, rivers, springs, taps and wells was investigated in peri-urban settlements around Harare. Escherichia coli, Salmonella sp., Vibrio cholerae and faecal streptococci were present in all water sources except for the boreholes and bowsers. Rivers, lake and wells showed the greatest diversity ...

Top Water/ Borehole Drilling Companies in Uganda (East Africa)
Rural water being a source for health, an essential nutrient and a building block for peoples’ lives in local communities cannot be sustained without external support in form of boreholes as they are the ‘surefire’ answer to providing fresh water in rural communities. A borehole is simply a deep-hole or a shaft sunk into the earth purposed forobtainingwater. Boreholes can be ...

Microbiological assessment of private drinking water supplies in Co. Cork, Ireland
The microbiological quality of 75 private drinking water supply boreholes in Co. Cork, Ireland was assessed in order to determine the incidence of contamination and the potential pathways of such contamination. Microbiological analysis was carried out using the membrane filtration technique for the recovery of thermotolerant (faecal) coliforms. The sanitary protection of the supplies was ...

Inspection Cameras for the Mining, Geological and Well Industry
When it comes to Borehole inspection requirements we can think of various industries and environments that these activities are engaged in. 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. The ...

Borehole logging case study
Corozal, Puerto Rico GeoView was tasked to conduct borehole geophysical logging of at a groundwater extraction well in the rural area of the Municipality of Corozal, Puerto Rico. Prior groundwater tests indicated possible contamination of the groundwater. The study area was primarily underlain by stratified, mostly dark gray basaltic tuff, andesite and basalt porphyry rocks assigned to the Los ...

Sustainable Groundwater Management in Indian Wells, CA - Case Study
Motivation The Indian Wells Valley in the Mojave Desert of California is home to the China Lake Naval Air Warfare Station, the city of Ridgecrest, and significant agricultural and mining interests. Residents and industries in the valley depend on groundwater, which has been depleted due to overuse since the 1960s. The Indian Wells Valley Groundwater Authority required accurate information on the ...

The Italian Job
Open loop systems abstract groundwater from one or more boreholes. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate well or body of water. The supply and return lines need to be placed far enough apart to ensure thermal recharge of the source. The key issues for open loop systems relate to borehole yields, licensing and, most importantly, ...

Drinking water quality and source reliability in rural Ashanti region, Ghana
Site-specific information about local water sources is an important part of a community-driven effort to improve environmental conditions. The purpose of this assessment was to gather this information for residents of rural villages in Ghana. Sanitary surveys and bacteriological testing for total coliforms and Escherichia coli (EC) using Colilert® were conducted at nearly 80 water ...
