Lysimetric studies for modelling radioactive contaminant transport in soils
To assess the movement of contaminants in the soil mass surrounded by near/subsurface waste repository, researchers have developed several mathematical and numerical modelling techniques. However, most of these techniques consider remolded state of soil mass, which fail to reproduce exact in situ conditions and also have used inactive salts as model contaminants. Hence, in order to model ...

Making MGP Wastes Beneficial
More than 11 billion gallons of coal tar were generated at MGP sites in the United States from 1816 to 1947. The types and quantities of waste discharged to surface waters from MGPs vary from site to site, and the disposition of several billion gallons is unknown and remains unaccounted for. Numerous locations in the United States have sediments and soils contaminated with wastes generated from ...

Removal of Oil in Groundwater With Oil Skimmer - Case Study
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 ...

Environmental and health concerns regarding the quality of water in a poor suburb of Kinshasa in the Democratic Republic of Congo
In many developing countries, the scarcity of potable water is an ongoing challenge. Even when water is plentiful, its quality may be unsuitable for household use such as in the city of Kinshasa in the Democratic Republic of Congo (DRC) which is the study area for this investigation. Shortage of potable water has forced inhabitants in the city to rely on water wells dug without adherence to ...

A dynamite job? Cleaning up trinitrotoluene waste at the Apache powder superfund site.
The clean up of trinitrotoluene (TNT) wastes and contaminated soils from an abandoned TNT salvage operation is underway at the Apache Powder Superfund Site in Cochise County. Clean-up operations involved an unexploded ordnance (UXO) survey, on-site pre-burn of high-grade materials, excavation, and off-site disposal. Approximately 5,400 lb of high-grade TNT wastes (averaging approximately 33 ...

Mathematical modeling of heavy metals contamination from MSW landfill site in Khon Kaen, Thailand
Kham Bon landfill site is one of many municipality waste disposal sites in Thailand which are in an unsanitary condition. The site has been receiving municipality wastes without separating hazardous waste since 1968. Heavy metals including, Pb, Cr and Cd are found in soil and groundwater around the site, posing a health risk to people living nearby. In this research, contamination transport ...

Spatio-temporal assessment of groundwater level and quality in urban coastal city Puri, India
Puri city is situated on the shoreline of Bay of Bengal and groundwater is the only source available to meet the city water supply mainly from two demarcated water fields. Due to the anthropogenic activities and absence of sewerage system, groundwater quality is deteriorating through open discharges of domestic waste, open defecation, septic tanks, soak pits, contaminated water pools, unorganized ...

NORMs contamination treatment using Ivey-sol technology
NORMs (naturally occurring radioactive materials) are found almost everywhere, and many natural materials, such as the earth’s crust, contain such radioactive materials. So what happens when oil and gas activities such as petroleum refining and natural gas extraction, disturb such radioactive material? They can alter the natural background radiation — the radiation that we are ...

Pollution level detection in dump clay liners by hyperspectral imaging
Landfill is the most common and cost–effective method of waste disposal, with collection and transportation accounting for 75% of the total cost. A key point in waste disposal is the picking up and the drainage of percolation fluids to limit the risk of groundwater contamination. Aim of this study was to evaluate the possibility to develop fast and reliable methods to perform an in situ ...

Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate
Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

Lead contamination in soil and groundwater in and around a lead processing industry: a case study
Environmental pollution is of major concern across the world, which is affected by a variety of contaminants. Lead is one of the major heavy metals used in industrial activity. Unscientific handling and disposal of lead bearing residues or lead waste has led to contamination of the surrounding soil and water environment. A detailed investigation of soil and groundwater was carried out in and ...
