A case of environmental contamination is defined as 'serious' if >25 m 3 soil or >100 m 3 groundwater is contaminated above the intervention value. The values presented below are from Annex 1, Table 1, "Groundwater target values and soil and groundwater intervention values".
Soil Guideline Values (SGVs) are figures which are used in non-statutory technical guidance for assessors carrying out risk assessments to determine whether land is considered "contaminated" under United Kingdom law, that is "land which appears to... be in such a condition, by reason of substances in, on or under the land, that (a) significant harm is being caused or there is a significant ...
A study investigating the heavy metal pollution in the vicinity of the smelter reveals that elevated levels of nickel and copper were found in the soil; values going as high as 5,104ppm Ni, and 2,892 ppm Cu within a 1.1 km range of the smelter location. Other metals were also found in the soil; such metals include iron, cobalt, and silver.
Phase II Environmental Site Assessment is an "intrusive" investigation which collects original samples of soil, groundwater or building materials to analyze for quantitative values of various contaminants. [11] This investigation is normally undertaken when a Phase I ESA determines a likelihood of site contamination.
Usually, pesticide standard value is regulated in residential surface soil (i.e., pesticide soil regulatory guidance value, or RGV), [1] drinking water (i.e., pesticide drinking water maximum concentration level, or MCL), [2] foods (i.e., pesticide food maximum residue level, or MRL), [3] and other ecological sections (e.g., air, surface water ...
Blue billy is a chemical or mineral [i] deposit often encountered in contaminated land. [1] The name is a reference to its distinctive bright blue colour, which can make it immediately obvious in other mud or soil. Chemically it is a form of Prussian blue.
Soil quality in agricultural terms is measured on a scale of soil value (Bodenwertzahl) in Germany. [6] Soil quality is primarily measured by chemical, physical, and biological indicators because soil function cannot easily be measured directly. [7] Each of these categories comprises several indicators that provide insight into overall soil ...
A soil family category is a group of soils within a subgroup and describes the physical and chemical properties which affect the response of soil to agricultural management and engineering applications. The principal characteristics used to differentiate soil families include texture, mineralogy, pH, permeability, structure, consistency, the ...
