Train derailment prompts contaminated land investigation - Case study

On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

Why You Should Monitor Groundwater?

What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

Guidelines for the use of mosses and soils in monitoring contaminant fallout

In 1999 Italy’s Environmental Protection Agency (ANPA) published a paper on the methods to be used in the case of mosses and soils. After nearly a decade, a review is advisable. The attached Guidelines take account of numerous experiments in the environmental field and include a short description of bryophyte biology. A great many pollutants are present in our environment. In addition to ...

Optimal groundwater contamination monitoring using pumping wells

This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...

Contamination at ANA Shipyard

ANA Shipyard is located on Elizabeth river and during additional construction work, it was discovered that the ground water was contaminated with free product due to soil contaminated with a mixture of oils and greases. Excavation of soil and replacement with clean dirt was not an option since it would contaminate the river. It was recommended by the Virginia DEQ that the cleanup should be done ...

Bioremediation of pollutant-contaminated water

Raw water resources in Kafr El-Sheikh Governorate are affected by many contaminants particularly during the winter season and low demand period of the Nile River, in which water level decreases and organic matter increases resulting in decreased dissolved oxygen, and increased ammonia, nitrite and bacterial load in the water. In this study, physicochemical and microbiological characteristics ...

Bioremediating Explosives Contaminated Soil

From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

Bioremediation with compost of a diesel contaminated soil: Monitoring by dehydrogenase activity and basal respiration

The effect of compost on hydrocarbon degradation was determined during a 120-d incubation period. An evaluation of soil basal respiration and dehydrogenase activity as a monitoring instrument for the bioremediation process of soil contaminated with commercial diesel-oil was carried out. Six soil samples were used: S (control, uncontaminated soil), CS (contaminated soil), CSS (contaminated and ...

The Mussel Watch approach and its applicability to global chemical contamination monitoring programmes

Although the use of biological monitors has become a standard practice in different national and international programmes over the past two decades, there are several complicating factors that need to be taken into account when sampling over large geographical extensions. Species availability, physiological conditions, and climatic variables encountered over large areas of study are a few of the ...
