-
Water quality monitoring in a watershed requires easy to use field meters that are accurate and reliable.
For watershed monitoring, samples are needed from multiple locations that are typically far from each other. As traveling to remote locations is itself very time consuming, the time spent on doing the water analysis, from sample collection to getting the results, becomes even more critical. In West Virginia, some of the types of water bodies in the watershed, like blackwater rivers, possess ...

Impact of agricultural activities on phosphorus in streams draining into Opa Reservoir Ile Ife, Nigeria
Phosphorus is noted as the limiting factor of eutrophication. We investigated the impact of different agricultural land use (mixed cropping, horticultural garden and fallow land) on the phosphorus loading of a reservoir. Soil samples were analysed for pH, particle size distribution, organic matter, available P and erodibility index calculated. Water samples analysed for biological oxygen demand ...

Environmental assessments and audits at aviation facilities
Environmentalists are all about “green”, but there is another type of green that is associated with being environmentally compliant – money. There are primarily two types of environmental assessments that are performed at aviation facilities that can affect a company’s bottom line: Phase I/II Environmental Site Assessments (ESA) and General Facility Audits. The ESAs are also referred to as due ...

Organic compounds migrating from plastic pipes into water
Case studies were carried out to identify potential chemical contaminants migrating to drinking water from polyvinyl chloride (PVC) or polyethylene (PE) pipes, available on the Polish market. Analyses were carried out by gas chromatography (GC) coupled with mass spectrometry (MS). Analysis of organotin compounds in water in contact with PVC pipes from different manufacturers found variability: ...

Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution
To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...
