It includes different steps: Answering the Initial Ecological Assessment Screening Questions found in that methodology document If "yes" is the response to any of the four questions, then the sampling findings should be compared to the HSCA Screening Levels for ecological sediment, surface water, and surface soil, as appropriate. If any ...
Clean-up may not just be on your property but any other property including surface and groundwater that may have originated on your property. A Phase I ESA provides the appropriate level of “due diligence” in the transaction. ...
Southwest Giza area is one of the most complicated regions in Egypt because of the combination of agricultural, industrial and urbanization activities with few studies about water resources contamination with heavy metals. In this study, ten surface water samples and eight groundwater samples were collected and analyzed for ...
This situation makes it necessary to explore other possibilities, for example, conjunctive use of groundwater and surface water. The objective of this work was to describe the dynamic and geochemical relationships between surface water and groundwater in the medium-low basin of the Ají stream. ...
An automated solid-phase microextraction gas chromatography/mass spectometry (SPME-GC/MS) method was developed for the determination of semi-volatile pesticides from several classes with a wide range of polarities in an environmental matrix, and validated according to the rigorous standards of a large commercial laboratory reporting data requiring regulatory acceptance with the purpose of ...
Therefore, the federal environment agency (UBA) supported a project that aimed to investigate near-surface groundwater samples in regions of high livestock density and high risk of groundwater exposure to antibiotics. ...
This study investigates the drinking water (groundwater and surface water) quality and potential risk assessment along mafic and ultramafic rocks in the Swat district of Khyber Pakhtunkhwa Provence, Pakistan. For this purpose, 82 groundwater and 33 surface water samples were collected and analyzed for ...
One of the key threats to groundwater and surface water quality in Ireland is the impact of poorly designed, constructed or maintained on-site wastewater treatment systems. ...
To adhere to the regulatory compliance monitoring of external gamma level, radon and long–lived alpha activity of ore dust is carried out in uranium mines. Apart from this, surface contamination is also monitored in radiologically important areas of ore processing plant. ...
Whether sampling surface water or groundwater, conducting soil investigations, making air quality measurements or collecting soil-vapour samples, LSPECS is flexible, adaptable and robust. ...
On-site wastewater treatment systems (OWS) are a potentially significant non-point source of nutrients to groundwater and surface waters, and are extensively used in coastal North Carolina. The goal of this study was to determine the treatment efficiency of four OWS in reducing total dissolved nitrogen (TDN) and dissolved organic carbon (DOC) concentrations ...
PROJECT: GPR survey with confirmatory drilling + soil and water sampling / analysis LOCATION: Spokane, Washington PROJECT DESCRIPTION: Designed and performed a tight-line / saturation Ground Penetrating Radar (GPR) survey of an active retail property, to determine the presence, if any, of buried 1950s-vintage underground storage tanks (USTs). ...
Prudent interventions for reducing selenium (Se) in groundwater and streams within an irrigated river valley must be guided by a sound understanding of current field conditions. An emerging picture of the nature of Se contamination within the Lower Arkansas River Valley in Colorado is provided by data from a large number of groundwater and ...
The hydraulic properties of the aquifer were tested, and soil, surface water and groundwater samples were collected at various times in the year. ...
This paper discusses the results of the systematic measurement of activity concentration of 222Rn in groundwater and surface water samples of two major rivers of coastal Karnataka, namely, Kali and Sharavathi. Water radon concentrations were measured using an Alpha Guard PQ2000Pro (Genitron GmbH) equipped with an appropriate unit (AquaKIT), ...
Enhanced infiltration caused by groundwater extraction is suspected to be both a prime factor in the disappearance of a lagoon system at the Toluca Basin and a potential risk to long-term groundwater quality. A combined approach of field investigation and numerical modeling was adopted to assess the groundwater-surface water ...
