Use of geostatistics to evaluate the monitoring well network of a TCE plume
This paper summarises the use of geostatistics to evaluate an existing network of wells in a groundwater monitoring program. The primary objective was to evaluate whether selective well removal would result in a comparable characterisation of a trichloroethylene (TCE) plume. For adequate characterisation, it is important to retain enough wells to evaluate areas with higher concentrations and to ...

Evaluation of regional groundwater quality using PCA and geostatistics in the urban coastal aquifer, East Coast of India
A systematic groundwater quality-monitoring program was conducted, and a total of 201 groundwater samples were collected. Multivariate and geostatistical techniques were employed to investigate major contamination types and its spatial characteristics in the study area. Principal Component Analysis (PCA) reveals that salinity (Factor 1) and nutrient (Factor 2) are very predominant contaminants in ...

EQuIS milestone
EQuIS now contains over 15 million chemical/physical discrete monitoring results after the recent completion of the EDMS (Closed Landfills) database migration. Growth for other MPCA Remediation and Solid Waste programs will depend on the rate that labs and contractors adopt the new standard lab and field EDD submittal formats and on associated location establishment. Groundwater and surface water ...

Design Considerations for Multilevel Monitoring Wells
Untitled Document ABSTRACT Much has been written about the advantages of multilevel (multiport) monitoring wells over clustered or nested monitoring wells, however, there is little published information that provides helpful hints and 'dos and don'ts' for planning successful multilevel well projects. This paper discusses the differences in both design and construction ...

Case Study: Granite Rock
The world is changing. Consider the environment: In just a couple of decades, our knowledge of the world around us and how we affect it has caused significant shifts in the way we act. The best example of this lies with our corporate culture, as companies have to consider their impact on the world as well as their overall profitability. Industries that rely on the earth are in a precarious ...

Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures
Untitled Document Background The Regional Superfund Ground Water Forum is a group of ground-water scientists, representing EPA's Regional Superfund Offices, organized to exchange information related to ground-water remediation at Superfund sites. One of the major concerns of the Forum is the sampling of ground water to support site assessment and remedial performance ...

The Effectiveness of Intrawell ground water monitoring statistics
Abstract The reality of the new statistical evaluation requirements for ground water at Subtitle D facilities are being felt nationwide. All too often these requirements are resulting in unnecessary increases in ground water monitoring costs and erroneous indications of facility impacts. For example, a common situation faced by many older facilities is that there is statistically significant ...

Managing RCRA statistical requirements to minimize ground water monitoring costs
Abstract This paper will provide an overview of how ground water monitoring statistical choices can significantly impact a facility's ground water monitoring costs. For example, a recent study analyzed the long term ground-water monitoring cost impacts of different statistical analysis approaches on over 20 landfills. The study found that the choice of statistical approach can make over a 50% ...

Brazil - updated soil contamination regulations
While Brazil has not changed its waste generator liability since adopting Law 6.938 in 1981, it has updated and altered requirements for generators. Most recently, the Brazilian National Council on the Environment (CONAMA) adopted CONAMA Resolution 420/2009, establishing guidelines and criteria for the management of contaminated sites. CONAMA Resolution provides for the creation of soil quality ...
