The phrase "migration of pollutants" is correct and can be used in written English.
It refers to the movement or spread of harmful or unwanted substances in the environment. Example: The migration of pollutants from the industrial site to the nearby river has caused serious damage to the ecosystem.
The injection of rainwater into the well has the effect of locally increasing the water level and preventing or slowing the migration of pollutants from nearby sources of pollution such as septic tanks.
The migration of pollutants is controlled not only by natural groundwater flow, but it is also strongly influenced by water drainage during deep mining, an activity that causes the multi-source pollutants to migrate to the mining centre.
Metakaolin (MK), widely used for high-performance concrete admixtures, is introduced into improving the percolation behaviors of cement-stabilized soft clays, which is a key performance when analyzing the permeability and consolidation in the grounds modified by deep mixing methods etc., the underground water seepage and the migration of pollutants in waterproof curtains by grouting methods etc.
Thus, the method proposed here can also be used for predicting migration time of pollutants to a stream or river from its surroundings through subsurface flow in a watershed.
"We will chart migration pathways of pollutants that have traveled both vertically and horizontally over all these years, using mathematical modeling.
If similar trend continues beyond the unsaturated zone, there could be greater migration of dissolved pollutants from the leachate along with hydraulic gradient towards groundwater system, unless other chemical processes such as adsorption, ion exchange and complexations with less mobile compounds occur.
An accurate estimation of this parameter in a watershed is crucial as it provides information about probable time of migration of a pollutant to receiving water bodies in contact with the watershed via the subsurface (Jury 1975a, b; Jury and Weeks 1978) drains.
The migration and transformation of pollutants are usually coupled with the redox of FeII FeIII−.
A finite element subsurface flow (FEFLOW) system was utilized to construct a numerical model that can analyse and predict the migration of multi-source pollutants during groundwater pumping and drainage in the mining area.
The increased retention of bacteria at the gas liquid interface indicates the presence of the interface is an important factor in limiting pathogen migration, evaluating biocolloid-facilitated transport of pollutants, and developing bioremediation strategies for unsaturated porous media.
Scavengers always set fires openly on site to the waste in search of retrievable materials, a situation which will normally results in thick fumes and ash formation, dissolution and migration of chloride compounds and other pollutants into nearby surface water.
