Abstract:

The past human activities, mainly that related to industrial development caused in many cases a strong contamination of soil, subsoil environment and of groundwater. This type of pollution is a concern because it poses risks to human health and to the ecosystem. More than this, such areas may not be used for new development, requiring solutions for remediation. The management of these sites consists of three main activities: characterization, remediation and, finally, redevelopment. The paper presents a case study dedicated to the first step of contaminated sites management, respectively characterization. This phase is very important, a good characterization could ensure a performant solution for the second step – remediation. Two new techniques for site characterization are presented, as technical principles, but also as performances obtained for the mentioned case study.

Abstract:

Coal tar, creosote, and similar viscous non-aqueous phase liquids (NAPLs) behave in alluvial soils in a manner significantly different from that of less viscous NAPLs, such as gasoline and chlorinated solvents. Their unique behavior is due to the interaction of their physicalchemical parameters: a density often greater than water, a viscosity significantly greater than water, and an interfacial tension that yields a positive initial spreading coefficient at airwaterNAPL interfaces. This results in slow, creeping flow that causes long-term contamination at former manufactured gas plants and wood-preserving sites and of their adjacent surface waters. Multiphase simulations of this creeping flow are shown for a site along the lower Fraser River near Vancouver, British Columbia, and the long-term consequences of the migration of viscous NAPLs in alluvium are discussed from the perspective of site characterization and brownfields redevelopment.Key words: creosote, coal tar, multiphase simulation, brownfields, NAPL.

Abstract:

With the rapid development of industrialization and urbanization in China, many of industrial enterprises have relocated from the original sites, which have produced a large number of contaminated sites. The environmental risk assessment and management must be carried out imminently. This paper analyzes the removal of contaminated sites happened in China currently, and through combing the contaminated sites features and aspects of human health pathways, analyzed environmental risks of contaminated sites recycling. As for the health risk assessment, we focus on data collection, toxicity assessment, exposure assessment and risk characterization. The paper also describes the regulations and technical standards of contaminated sites risk assessment, which is used in our country currently. Finally the paper summarizes the problems and gives suggestions for the risk assessment research of contaminated sites.

Abstract:

With a view to conserving or improving soil ecosystem services, environment-friendly techniques, such as bio- and phytoremediation, can effectively be used for the characterization, risk assessment, and remediation of contaminated agricultural sites. Polyannual vegetation (meadows, poplar, and cane stands) is widely considered the most efficient tool for remediation (extraction of bioavailable fraction of contaminants), for undertaking safety measures (reducing the mobility of contaminants towards other environmental compartments), and for restoring the ecosystem services of contaminated agricultural sites (biomass production, groundwater protection, C storage, landscape quality improvement, and cultural and educational services). The roles of agronomic approaches will be reviewed by focusing on the various steps in the whole remediation process: (i) detailed environmental characterization; (ii) phytoremediation for reducing risks for the environment and human health; (iii) agronomic management for improving efficiency of phytoremediation; and (iv) biomass recycling in the win-win perspective of the circular economy.

Abstract:

Soil contamination is a widespread problem and action needs to be taken in order to prevent damage to the groundwater and the life around the contaminated sites. In Sweden, it is estimated that more than 80,000 sites are potentially contaminated, and therefore, there is a demand for investigations and further treatment of the soil. In this paper, we present the results from a methodology applied in a site contaminated with chlorinated solvents, for characterization of the contamination in order to plan the remediation and to follow-up the initial step of in-situ remediation in an efficient way. We utilized the results from three different methods; membrane interface probe for direct measurement of the contaminant concentrations; seismic refraction tomography for investigating the depth to the bedrock interface; and direct current resistivity and time-domain induced polarization tomography to acquire a high-resolution imaging of the electrical properties of the subsurface. The results indicate that our methodology is very promising in terms of site characterization, and furthermore, has great potential for real-time geophysical monitoring of contaminated sites in the future.

Abstract:

Polycyclic aromatic hydrocarbons (PAHs) are toxic and carcinogenic environmental contaminants originating from different sources; petrogenic, pyrogenic or biogenic. Depending on the source of contamination there will be different ratios of PAHs and the effects on the environment will differ. Petrogenic sources will be higher in concentration of alkyl substituted PAHs (APAHs) while pyrogenic sources will be higher in parent PAHs. In the present study a GC/MS method was developed to separate and calibrate PAHs, dibenzothiophenes and alkyl substituted PAHs in a mix containing 49 standards. The method was able to differentiate between PAHs and APAHs with the same mass number; up to six different compounds with the same mass number was separated. The developed method was used to analyse six different soil samples from various contamination sites. PAHs, APAHs and dibenzothiophenes were identified and quantified in all samples. In order to establish the source of contamination, the distribution pattern, the ratio between different PAHs, and the ratio between APAHs and parent PAHs were used. There was a higher ratio of APAHs/PAHs and a lower ratio between the parent PAHs in the soil samples from sites contaminated with oils compared to the other samples, indicating petrogenic source.
Polycykliska aromatiska kolväten (PAH) är giftiga och cancerframkallande miljögifter som härstammar från olika källor; petrogena, pyrogena eller biogena. Olika föroreningskällor kommer att ha olika förhållanden av PAH och effekterna på miljön kommer att skilja. Petrogena källor innehåller högre koncentrationer av alkylsubstituerade PAH (APAH) medan pyrogena källor kommer att ha högre koncentration av PAH. I denna studie har en GC/MS-metod utvecklats för att separera och kalibrera PAH, dibensotiofener och alkylsubstituerade PAH i en blandning innehållande 49 standarder. Metoden kunde skilja mellan PAH och alkylsubstituerade PAH med samma masstal; upp till sex olika föreningar med samma masstal särskildes. Den utvecklade metoden användes för att analysera sex olika jordprover från olika föroreningsplatser. PAH, APAH och dibensotiofener identifierades och kvantifieras i samtliga prover. För att fastställa föroreningskällan användes fördelningsmönstret för APAH och PAH, förhållandet mellan olika PAH och ration mellan APAH och PAH. Det fanns en högre kvot APAH/PAH i jordprover från områden som var förorenade med olja, vilket indikerar på petrogena föroreningskällor.

Poluentes presentes em um solo contaminado podem ser transportados para áreas próximas, devido aos processos de dispersão de poluentes, principalmente pelo fluxo de águas superficiais e subterrâneas, formando áreas contaminadas não cadastradas, chamadas nesse trabalho de "áreas com contaminação difusa". Com o objetivo de identificar e mapear áreas com contaminação difusa na área delimitada no Projeto Urbano "Eixo Tamanduatehy" (PET), o conceito de base de dados georreferenciados (geodatabase) foi utilizado, com uma formulação em três módulos, source, pathway e receptor. A geodatabase elaborada para este estudo foi alimentada com dados obtidos junto às agências ambientais regionais e locais, à prefeitura do município de Santo André e outras instituições nacionais, com informações sobre a localização dos lotes contaminados, os contaminantes, os aspectos hidrogeológicos, geológico-geotécnicos, além dos aquíferos, córregos e rios da área de estudo. A base de dados também foi alimentada com informações sobre poços de monitoramento as quais foram obtidas a partir de 17 processos, protocolados na Companhia Ambiental do Estado de São Paulo (CETESB), referentes às áreas contaminadas na área que abrange o PET. Os resultados indicaram um predomínio de poluição em escala regional por metais, como bário, chumbo, níquel, e também por organoclorados resultantes da degradação do tetracloroetileno (PCE). A partir dos mapas gerados para o fluxo subterrâneo, de isolinhas de concentração e de suscetibilidade à contaminação por metais e solventes halogenados, foi possível indicar sete áreas (regiões) com potencial de contaminação difusa na região do PET. Portanto, com a integração dos dados geoambientais em uma geodatabase, utilizando softwares SIG, o estudo foi capaz de mapear as regiões com grande potencial de contaminação difusa, na área de influência do PET, indicando a aplicabilidade de geodatabase em escala regional para otimizar o manejo dessas áreas contaminadas, como também o planejamento urbano em escala regional. Um mapeamento mais preciso e atualizado poderia ser realizado se uma base de dados georreferenciados nacional com escala de trabalho apropriada estivesse disponível, e se os dados em relatórios de licenciamento ambiental e de gerenciamento de áreas contaminadas fossem padronizados e disponibilizados de forma integrada.
Pollutants in contaminated soils can be transported to surrounding areas due to pollutant dispersion processes, especially by the flow of surface and groundwater, forming unregistered contaminated areas, called "areas with diffuse contamination". To identify the areas with diffuse contamination within the limits of the "Tamanduatehy Axis" Urban Project (PET), a geo-referenced database (geodatabase) concept was used, with a three-module design: source, pathway and receptor. According to data collected from regional and local environmental agencies, Santo André's city hall, and other national institutions, information on the location of contaminated sites, contaminants, hydrogeological and geological-geotechnical aspects, contamination of the aquifers, streams and rivers of the study area were fed into the geodatabase. The database was also created with information from monitoring wells in which seventeen processes of the contaminated sites throughout the PET and registered by CETESB were consulted in order to complement the geo-environmental parameters interpretation. The results indicated a predominance of regional scale pollution by metals, such as barium, lead and nickel, and by organochlorines resulting from the degradation of tetrachlorethylene (PCE). It was possible to map seven areas with potential diffuse contamination in the PET region, based on the interpretation of the underground flow maps, concentration isolines, metals and halogenated solvents contamination susceptibility. Therefore, with the integration of geo-environmental data into a geodatabase using GIS software, the study was able to map the regions with great potential for diffuse contamination in the PET's area of influence, indicating the applicability of the geodatabase on a regional scale to optimize the management of contaminated areas, as well as urban planning on a regional scale. More accurate and upto-date mapping could be done if a national georeferenced database with appropriate work scale was available and if the data in environmental permitting and contaminated area management reports were standardized and made available in an integrated manner

Abstract:

A creosote treatment facility was active during the 1950’s and 1960’s at a railroad tie yard site. In 1990, creosote contamination was discovered along a creek bank at the site. Phytoremediation was selected as the remedial technology and hybrid poplar trees were planted at the site in 1997. A research project was designed to: 1) characterize the site through collection of soil and ground water samples; 2) assess phytoremediation effects of 3 grasses, clover, fescue and rye, in creosote-contaminated surface soils; 3) perform assessment of the hybrid poplar tree phytoremediation system; 4) develop a hybrid poplar tree evapotranspiration model. This thesis is focused on the first and second items on the research agenda. Soil and ground water samples were collected and analyzed for 6 polycyclic aromatic hydrocarbons (PAHs), acenaphthene, fluorene, phenanthrene, fluoranthene, pyrene and chrysene. Site characterization revealed multiple creosote sources. Areal subsurface bedrock DNAPL distribution, approximately 6500 ft², was much greater than previously reported. Total PAHs (Σ 6 PAHs) in the soil and ground water ranged from below detection limits (BDL) to 8,276 mg/kg and BDL to 1.58 mg/L, respectively. Aqueous phase PAHs should be available for hybrid poplar tree and microbial uptake. Dissolution and diffusion of PAH constituents from the free product phase to the aqueous and soil phases contaminated both matrices. PAH cosolvency effects were also evident. The presence of more soluble PAHs in the aqueous phase enhanced the solubility of two hydrophobic PAHs, chrysene and benzo(b)fluoranthene. Phytoremediation effects of fescue, rye, and clover grasses were assessed in creosote-contaminated surface soils. Over the 9 month period, clover grass growth was very poor. Clover data was not used in comparative analyses. Rye and fescue grasses exhibited acceptable growth. In planted and control (unplanted-amended) plots, acenaphthene, fluorene, phenanthrene, fluoranthene, and pyrene soil concentrations were reduced 72, 50, 73, 55 and 49 percent, respectively. Chrysene reduction was not statistically significant. During the first 4 months of the study, dry site conditions limited grass growth and subsurface biological activity. The site received approximately 16 inches of precipitation during the last 3 months of the study, including multiple, intense precipitation events. The subsurface was saturated for prolonged periods of time and oxygen transfer to indigenous microorganisms was likely limited. The root structures of fescue and rye grasses were neither dense nor complex enough to promote phytoremediation effects. PAH reductions were generally greater for constituents with higher aqueous solubilities. It is thought that PAH losses were primarily due to solubilization and/or microbial uptake.

Abstract:

Groundwater geochemistry and flow have been studied in Gotra, West Bengal, India, where geogenic arsenic contaminates groundwater at levels above World Health Organization limits. The village is situated upon the natural levee of an abandoned channel, which terminates a fluvio-deltaic depositional sequence. The formerly prograding meander bend deposited point-bar sands during the Holocene that now comprise the 30m-thick shallow aquifer, while incising deeper Pleistocene sands and a shallow floodplain sequence. Hand-pumped tubewells are completed in point-bar sands, whereas irrigation wells are generally screened within Pleistocene materials. Hydraulic conductivity of the point-bar aquifer is approximately 5x10⁻⁴ m/s. A leaky-confining layer of levee/crevasse splay deposits overlies this aquifer beneath crop fields. Near the village, the shallow aquifer is confined by channel-fill silts that have an estimated conductivity of 1x10⁻⁷ m/s. The paleohorizon separating Holocene and Pleistocene sediments is marked locally by fine-grained material comprised of organic material and a hard clay. Groundwater elevations vary 7m over the course of a given year due to monsoonal climate and groundwater extraction. Convergent flow towards shallow pumping wells is a salient feature during irrigation season, and persistent localized downward gradients suggest that meteoric recharge and pumping are the predominant groundwater sources and sinks. A northeast trending geochemical gradient in the point-bar aquifer suggests that local flows transporting arsenic are directed away from the channel-fill silt. Concentration gradients of terminal electron acceptors and redox reaction products in the shallow aqueous profile also coincide with a flowpath originating from this unit. A numerical model of groundwater flow was developed based on a conceptual model derived from field observations to investigate controls of arsenic transport and to provide a context in which to interpret geochemical data. Short- (7-day) and long- (3-year) term transient simulations were implemented to simulate groundwater flowpaths, water balance, and average residence times. Modeling results support field observations that contamination is related to the channel-fill unit deposit, and suggest that the water balance has been significantly altered compared to pre-irrigation conditions. Results also suggest contaminant flushing will not occur over a human timescale.

Abstract:

Rikke Granum Andersen In situ characterization and quantification of phytoremediation removal mechanisms for naphthalene at a creosote-contaminated site Phytoremediation is an attractive remediation technology due to its relative low cost and maintenance requirement. Acceptance of phytoremediation requires that the contaminant removal mechanisms are characterized and demonstrated in the field. Quantification of contributions from each mechanism to the overall remediation rate is crucial for optimization of phytoremediation systems, risk management and prediction of the total remediation time. The objective of this research was to characterize and quantify removal mechanisms for naphthalene at a creosote-contaminated site with poplar trees in Oneida, Tennessee. Groundwater monitoring for seven years in the surficial aquifer at this site demonstrated a reduction in polycyclic aromatic hydrocarbons (PAHs) with selective removal of naphthalene and three-ring compounds. Naphthalene mass loss mechanisms investigated at this site are biodegradation in the saturated zone, volatilization and biodegradation in the vadose zone and phytovolatilization. This is probably the most comprehensive field study of PAH phytoremediation mechanisms conducted to date. The significance of this research is to contribute to predictions of remediation time and end result for phytoremediation of PAHs. The understanding of in situ factors controlling each mechanism can facilitate future optimization of phytoremediation systems as well as improve risk assessment and monitoring strategies. Biodegradation rates were determined for different conditions at this site with in situ respiration tests, laboratory soil microcosms and laboratory soil columns. The combined remediation mechanisms of volatilization and biodegradation in the vadose zone were investigated in the field and in laboratory columns. Field measurements show that lower groundwater elevations in the summer and early fall lead to elevated groundwater concentrations of naphthalene and increased volatilization. The increase in the fraction of the porespace occupied by gas (gas saturation) in the unsaturated zone during the summer and fall further enhances the volatilization by increasing effective diffusion rates. Water consumption and interception by the phytoremediation system are believed to enhance mass transfer to the vadose zone. Column experiments and field measurements show that more than 90% of the naphthalene vapors are biodegraded within 5-10 cm above the groundwater table. The data indicate that biodegradation increases the overall volatilization flux out of the source by 10-300 times, when the source is exposed directly to the gas phase. In situ the naphthalene is generally dissolved from the source into the groundwater and then volatilezed from the groundwater to the gas phase. Under these conditions biodegradation in the vadose zone will still indirectly have an enhancing effect on the flux out of the source. This is the result of removal naphthalene from the soil gas by biodegrdation driving removal from the groundwater by volatilization, which in turn drives dissolution form the source into the groundwater. Phytovolatilization was quantified in flux chambers mounted on trees and calculated from transpiration rates. A laboratory uptake study and analysis of tree cores from the site provided supplementary evidence for naphthalene uptake by poplar trees. Phytovolatilization was detected throughout the year and was highest in the summer and fall when the groundwater concentrations were highest and transpiration was active. The role of biodegradation relative to physical removal mechanisms was compared for a year, for winter and summer conditions and with and without the impact of phytoremediation. Biodegradation of naphthalene in the saturated zone dominates by orders of magnitude over the removal by volatilization and phytovolatilization of naphthalene at this site. The removal of the total residual naphthalene mass was estimated to require up to 100 years with phytoremediation, but more than twice as long without phytoremediation. The estimated removal of naphthalene was three times larger in the summer than in the winter due to slower biodegradation in the saturated zone and smaller rates of volatilization to the vadose zone in the winter. The research shows that phytoremediation enhances the overall naphthalene removal, mainly by stimulating faster biodegradation in the rhizosphere and promoting mass transfer of naphthalene to the vadose zone followed by rapid vadose zone biodegradation. In the future, phytoremediation research focusing on the capillary zone is desirable.

Abstract:

Production water containing naturally occurring radioactive materials (NORM) has been collected in unlined artificial lagoons for evaporation in some Syrian oilfields. These lagoons have become highly contaminated with NORM and the situation has urged the operating oil companies in Syria to initiate a remediation program in cooperation with the Atomic Energy Commission of Syria. Part of this national remediation program is to characterize the contaminated soil as a preliminary step for disposal of this waste. Depth profiles of radioactivity have been established and found to be variable from one field to another. Factors that influence this distribution have been evaluated and are presented. Laboratory leaching experiments were performed using six 60-cm cores collected from highly contaminated areas in the oil fields. Results show that 226Ra is transferred to deep layers via erosion caused by disposal of production water and some heavy rain water that occurred in the past. This erosion process is mainly affected by the mineralogical compositions of the contaminated soil and the particle size distribution. Gypsum present in the soil has increased transfer of 226Ra from surface layers to deeper layers; water has caused some sink holes (caves) in those soils containing high amount of gypsum. In addition, 226Ra was also determined in different particle size soil samples before and after leaching experiments where small soil particles sizes were found to be moved downwards by water. Radium was only more concentrated in smaller particle sizes than larger ones in those samples containing low concentration of gypsum. In addition, halite content in the upper soil layers has increased the radium specific activity after leaching since it dissolved in water and moved to deeper layers.

Abstract:

The “Commissariat a` l’Energie Atomique” (CEA, French Atomic Energy Commission) has set up over the last 10 years an innovative methodology aiming at characterizing radiological contaminations. The application of the latter relies on various tools such as recently developed software platform called Kartotrak which is used in the expertise vehicles with impressive detection performances (VEgAS). A Geographic Information System tailored to radiological needs constitutes the heart of the platform; it is surrounded by several modules dedicated to sampling optimization, data analysis and geostatistical modeling, real-time monitoring (Kartotrak-RT) and validation of proper clean-up operations. This paper presents the purpose and the performances of the VEgAS which provides exhaustive instruments for the radiological surface characterization of sites.

Abstract:

The important first step in remediating contaminated sites is completing characterization. The process for characterization of natural environmental media (i.e., soil, sediment, surface water, groundwater) involves three basic steps: (1) develop a plan, (2) implement the plan by collecting information necessary to define the nature and extent of contaminants in the natural media, and (3) integrate, interpret and report the results. Because of budgetary constraints, these three steps are typically applied linearly with the expectation that by the end of one application of the process the site will be characterized with sufficient resolution to make decisions about remedial actions. Our experience over the past 13 years at a complex site in Tennessee has shown that this linear approach to characterization does not produce the desired resolution. Because characterization is typically a process of defining unknowns the inflexible nature of the linear approach makes it impractical to react as the conceptual understanding of site contaminants changes in response to the acquisition of new data. An alternative, flexible approach to characterization has been developed based on lessons learned. Over the past 3 years the flexible approach has cost-effectively produced the information needed for decision making.

Abstract:

This project presents several successful case studies in 15 categories of dredged material along with the statutory and regulatory requirements for beneficial use of dredged material in Illinois. The Illinois Environmental Protection Agency classification criteria for contaminated and uncontaminated dredged material are included with emphasis on Illinois requirements and characterization. Nine sites that have sandy dredged material stockpiles in Illinois are presented with suggestions for beneficially using the material. Based on this study, there is a high potential for beneficially using dredged material in Illinois for a range of projects. Currently, it is a state policy in Illinois to formally evaluate the history of possible nearby sources of chemicals that may have impacted the project sediments and to test the dredged material for chemical contamination before accepting for use on any highway project. However, the research team suggest that if the dredged material is mainly uncontaminated sand (e.g., greater than 80% sand) and is from a local site that does not have a history of contamination as determined by a formal evaluation, then the material is unlikely to be contaminated and may be easier to use and require little to no contaminate testing. Nevertheless, this proposed rule needs more testing and examination to be verified.
