Problems solved by technology

[0003] Under normal circumstances, it is necessary to conduct a detailed investigation on the pollution sources and usage of the site to accurately judge whether it is a typical petroleum hydrocarbon contaminated site. Due to the differences in geographical locations of different sites, the sampling process varies greatly, and there is currently a lack of corresponding established sites. General sampling method

[0019] specific implementation plan

[0020] The present invention is further described below in conjunction with example, but not limited thereto:

[0021] The soil and groundwater sampling method of a lubricant production plant relocation site, the steps are as follows.

[0022] Step 1. Through data collection, on-site survey and personnel interviews, it is clear that the site was once a lubricant production plant, which used and produced petroleum hydrocarbon raw materials. There are 5 emission sources and 2 potential leakage sources.

[0023] Step 2: For the first sampling, select 16 sampling points to sample 13 heavy metals (arsenic, cadmium, chromium (VI), copper, zinc, lead, mercury, nickel, manganese, silver, antimony, thallium, tin) on the site Investigate to determine whether the site soil is polluted by heavy metals, collect 80 soil samples;

[0024] Step 3: A total of 9 soil sampling points (S1-S9) were arranged for the second sampling, including 4 groundwater s...

Abstract

The invention relates to a special method for sampling soil and groundwater from a typical petroleum hydrocarbon contaminated site. The method comprises the following main steps: (1) collecting historical data and conducting interviews and site surveys in an early stage to confirm whether a site is a typical petroleum hydrocarbon contaminated site; (2) conducting primary sampling survey on the site, and distributing points for sampling in the site according to potential sources of pollution so as to confirm whether soil suffers from other contamination such as heavy metal contamination; (3) conducting secondary sampling survey on the site, wherein soil sampling points and groundwater sampling points are determined; and (4) conducting tertiary sampling survey according to the results of secondary sampling survey, distributing denser points for sampling in a possible contamination area range of the contaminated site, wherein mainly soil sampling points are laid out. The method provided by the invention is specifically for a special contaminated site, i.e., the typical petroleum hydrocarbon contaminated site, puts an end to the current situation that no specific specification is prescribed for sampling methods for petroleum hydrocarbon contaminated sites, and provides an effective method for sampling in petroleum hydrocarbon contaminated sites.

Description

[0001] The method relates to a soil and groundwater sampling method of a typical petroleum hydrocarbon polluted site, and belongs to the technical field of environmental assessment. Background technique [0002] With the rapid development of social economy, the problem of organic pollution of soil and groundwater is becoming more and more serious. As a special kind of polluted site, petroleum hydrocarbon polluted sites, due to the complexity of pollutants, changeable migration and transformation processes, will cause environmental damage after entering the environment. Large impact, and difficult to clean up. The sampling process in petroleum hydrocarbon contaminated sites has many unique characteristics, and nitrogen sampling is very difficult. [0003] Under normal circumstances, it is necessary to conduct a detailed investigation on the pollution sources and usage of the site to accurately judge whether it is a typical petroleum hydrocarbon contaminated site. Due to the dif...
