The in situ in ISCR is just Latin for "in place", signifying that ISCR is a chemical reduction reaction that occurs at the site of the contamination. Like ISCO, it is able to decontaminate many compounds, and, in theory, ISCR could be more effective in ground water remediation than ISCO.
The in situ in ISCO is just Latin for "in place", signifying that ISCO is a chemical oxidation reaction that occurs at the site of the contamination. The remediation of certain organic substances such as chlorinated solvents ( trichloroethene and tetrachloroethene ), and gasoline-related compounds ( benzene , toluene , ethylbenzene , MTBE , and ...
Hot zone, also written as hot-zone or hotzone, refers to an area or region that is significantly affected by environmental hazards or risks. It may refer to a location where there is high pollution, contamination, or a concentration of hazardous substances or activities.
Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, 2012). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase ...
1-in-100 flood – a flood with 1 in 100 chance of occurring in any given year (used as a safety requirement for the construction industry.); 20/30/10 standard - 20 mg/L Biochemical Oxygen Demand (BOD), 30 mg/L Suspended Solids (SS), 10 units of E. coli: the water quality standard for greywater use in toilets, laundry and surface irrigation.
Contamination control is the generic term for all activities aiming to control the existence, growth and proliferation of contamination in certain areas. Contamination control may refer to the atmosphere as well as to surfaces, to particulate matter as well as to microbes and to contamination prevention as well as to decontamination .
After years of debate, protests and late meetings, Boise’s new zoning code has arrived.. The new code, which dictates how and where development takes place in the city, took effect went live Dec ...
[14] [15] Riparian zones can play a role in lowering nitrate contamination in surface runoff, such as manure and other fertilizers from agricultural fields, that would otherwise damage ecosystems and human health. [16] Particularly, the attenuation of nitrate or denitrification of the nitrates from fertilizer in this buffer zone is important. [17]
