According to the division principle of above-mentioned stratigraphy assemblage type, the environmental hydrogeology in drafting District of Shanghai or area level region
Map section, various stratigraphy assemblage type have corresponding geographical position coordinates respectively.
（2）Determine the stratigraphy assemblage type belonging to contaminated site；The method specifically determined can have following two：
First method：The environmental hydrogeology situation data of contaminated site is consulted, to know its stratigraphy assemblage situation,
So that it is determined that the stratigraphy assemblage type belonging to the contaminated site；
Second method：According to the geographical position coordinates of contaminated site to be analyzed, pass through query steps（1）Middle drawn environment
Hydrogeological province map, determine the stratigraphy assemblage type belonging to the contaminated site to be analyzed.
（3）Determine the inside and outside river distribution situation of contaminated site, including three kinds of situations, equal nothing respectively inside and outside contaminated site
There is river to be distributed outside river distribution, contaminated site, have river distribution in contaminated site；
（4）Stratigraphy assemblage type and inside and outside river distribution situation according to belonging to contaminated site, are assessed in the contaminated site
The diffusion mobility direction of pollution sources and pollution depth, it is specific as follows：
【For I type】
When the stratigraphy assemblage type of contaminated site is I type, diffusion mobility direction and the dirt of contaminated site presence of pollution sources are assessed
Dye depth method be：
（a）If contaminated site is inside and outside when being distributed without river, water level or flow are relatively stable in contaminated site, and hydraulic gradient is smaller,
Convection action and hydrodynamic dispersion effect are relatively less obvious during contaminant transportation, because Groundwater Flow is slow, are detained
Time is grown, and the effect such as soil layer absorption, biodegradation is abundant, plays retarding effect to contaminant transportation, causes migration circle limited,
Therefore the diffusion mobility of pollutant in the horizontal direction can be neglected when being assessed；And in the depth direction, crust layer distribution
Pollutant in area is generally trapped at the top of crust layer, crust layer missing area, is moved under pollutant, but migration circle is limited and relatively has
It is small during river.
Therefore assessment result is：Pollution sources will be to depth direction diffusion mobility, and pollutant is finally stranded in the top of crust layer
Portion；If locally lying in missing area in crust layer, the top for being stranded in Muddy Bottoms stickiness soil layer is moved under pollutant；
（b）If have river distribution outside contaminated site, fill stratum is higher to groundwater level fluctuation sensitivity, during solute migration
Convection action influences substantially, secondly to act on for hydrodynamic dispersion；Crust layer poor permeability, convection current and mechanical dispersion effect are weak, point
Sub- disperse and suction-operated are stronger, therefore pollutant is generally trapped at the top of crust layer；Crust layer lacks area, and possibility is moved under pollutant
Property it is big, pollutant be most trapped at last Muddy Bottoms stickiness soil layer soil top；Due to the good retardation of crust layer, crust layer and
The Groundwater Flow of following soil layer is slow, causes pollutant migration circle under the conditions of different-thickness mealiness soil layer or silty sand ground poor
Other unobvious.
Therefore assessment result is：Horizontal direction to depth direction and sensing or away from river is carried out migration expansion by pollution sources
Dissipate, and pollutant is finally stranded in the top of crust layer；If locally lying in missing area in crust layer, move and be stranded under pollutant
The top of Muddy Bottoms stickiness soil layer；If the groundwater level in contaminated site is higher than river level, pollution sources point to river
Horizontal direction carry out diffusion mobility；If the groundwater level in contaminated site is less than river level, pollution sources deviate from river
The horizontal direction of stream carries out diffusion mobility；
（c）If have river distribution in contaminated site, when convection action influences to have river distribution more outside the venue during solute migration
More obvious, pollution migration circle is bigger；Crust layer distributed area pollutant is generally trapped at the top of crust layer.Crust layer lacks
Area, pollute and moved under solute, pollutant is most trapped at the top of the top of Muddy Bottoms stickiness soil layer at last, and migration circle has river more outside the venue
May be wider during stream.
Therefore assessment result is：Pollution sources in contaminated site are by depth direction and sensing or away from the level side in river
To carrying out diffusion mobility, pollution sources are pointing to or will be during away from the diffusion mobility of river direction（b）On the basis of improve migration expand
Area is dissipated, and pollutant is finally stranded in the top of crust layer；If locally lying in missing area in crust layer, moved under pollutant stagnant
Stay in the top of Muddy Bottoms stickiness soil layer；If the groundwater level in contaminated site is higher than river level, pollution sources point to
The horizontal direction in river carries out diffusion mobility；If the groundwater level in contaminated site is less than river level, the pollution sources back of the body
Horizontal direction from river carries out diffusion mobility.
【For II type】
When the stratigraphy assemblage type of contaminated site is II type, diffusion mobility direction and the dirt of contaminated site presence of pollution sources are assessed
Dye depth method be：
（a）It is distributed if contaminated site is inside and outside without river, when crust layer distribution is complete, rule is same as I type；Crust layer lacks area,
Moved under pollutant, but diffusion mobility is limited in scope, and is moved under pollutant and is detained position at the top of Muddy Bottoms cohesive soil.
Therefore assessment result is：Pollution sources will be to depth direction diffusion mobility, and pollutant is finally stranded in the top of crust layer
Portion；If locally lying in missing area in crust layer, the top for being stranded in Muddy Bottoms cohesive soil is moved under pollutant；
（b）If have river distribution outside contaminated site, fill stratum is higher to groundwater level fluctuation sensitivity, during solute migration
Convection action influences substantially, secondly to act on for hydrodynamic dispersion；Each soil layer suction-operated is relatively strong, the migration in crust layer distributed area
Rule is same as I type.Crust layer lacks area, moves that possibility is big under pollutant, and pollutant may be trapped in the top of Muddy Bottoms cohesive soil
Portion.
Therefore assessment result is：Pollution sources in contaminated site are by depth direction and sensing or away from the level side in river
To progress diffusion mobility, and pollutant is finally stranded in the top of crust layer；If locally lying in missing area in crust layer, pollute
The top for being stranded in Muddy Bottoms cohesive soil is moved under thing；If the groundwater level in contaminated site is higher than river level, pollute
The horizontal direction that river is pointed in source carries out diffusion mobility；It is dirty if the groundwater level in contaminated site is less than river level
Horizontal direction of the dye source away from river carries out diffusion mobility.
（c）If have river distribution in the contaminated site, convection action influences to have more outside the venue during contaminant transportation
River is more obvious when being distributed, and migration circle is bigger.Transport is same as I type substantially, only under crust layer missing area, pollutant
Moving delay position may be at the top of Muddy Bottoms stickiness soil layer.
Therefore assessment result is：Pollution sources in contaminated site are by depth direction and sensing or the level side away from river
To diffusion mobility is carried out, pollution sources will be described when pointing to or away from the diffusion mobility of river direction（b）On the basis of improve and move
Diffusion area is moved, and pollutant is finally stranded in the top of crust layer；If locally lying in missing area in crust layer, under pollutant
Move the top for being stranded in Muddy Bottoms stickiness soil layer；It is dirty if the groundwater level in contaminated site is higher than the river level
The horizontal direction that the river is pointed in dye source carries out diffusion mobility；If the groundwater level in contaminated site is less than river level
When, then horizontal direction of the pollution sources away from river carries out diffusion mobility.
【For III type】
When the stratigraphy assemblage type of contaminated site is III type, diffusion mobility direction and the dirt of contaminated site presence of pollution sources are assessed
Dye depth method be：
（a）If contaminated site is inside and outside when being distributed without river, water level or flow are relatively stable in contaminated site, and hydraulic gradient is smaller,
Convection action and hydrodynamic dispersion effect are relatively less obvious during contaminant transportation, because Groundwater Flow is slow, are detained
Time is grown, and the effect such as soil layer absorption, biodegradation is abundant, plays retarding effect to contaminant transportation, causes migration circle limited,
Therefore the diffusion mobility of pollutant in the horizontal direction can be neglected when being assessed；And in the depth direction, crust layer distribution
