METHOD OF EXPRESS-DETERMINING CONTAMINATION OF AREAS OF SOIL AND GROUNDWATER WITH CRUDE OIL AND REFINED PRODUCTS

摘要

FIELD: ecology.;SUBSTANCE: method comprises areal well-drilling of small diameter for shallow depth, sampling the subsurface gas, determination in samples the bulk concentration of methane and total hydrocarbons, as well as radon volumetric activity Rn²²² and Rn²²⁰. According to reduction of the radon volumetric activity and increase in concentration of methane and total hydrocarbons relative to the natural background the conclusion is made on the presence of area of contamination.;EFFECT: increase in informational content and reliability of determination.;1 tbl, 1 dwg
