Introduction
The most efficient techniques consist of preventing a pollution from reappearing,
In the 3 cases that interest us, we will see if it is possible to take action at the pollution source in order to avoid its reappearance.
When this is not possible, we will see which technical means are available,
It is actually necessary to take into account as soon as possible the flow polluted in order to treat and purify it.
Neglecting the management of the flow leads to contamination of the environment

For each type of pollution concerning the atmosphere, different types of treatment can be applied. As for noise pollution, the impacts can be reduced by :
isolating the sources when possible or by replacing the machines with less noisy ones isolant les sources
confing the areas where the machines operating with sound proof materials
limiting the speed at which the engins run, the insenisty of noise may diminue

Vacuum hoods
Near to the source or area where the dust is produced. These installations have to be adapted to the working conditions (operater, production mode…)
Protective clothing (masques, goggles) existe to avoid inhalation of vapors and solvants (see Module 5 « Prevention and protection of personnel »).

Collection from sewers on the site (or the sewer system for pretreatment of waste water) allow for the control of contaminated flows sending them towards the treatment unit.
These treatment units could be simple filters or internal waterwater treatment plants (WWTP).
If a WWTP is not on the site, the discharge could be sent towards the municipal WWTP with permission authorized by qualified services at the the town hall or by a water treatment agency.

Such equipment previously illustrated permet to diminue the pollution charge before the flow is disposed in the environment.
For example if hydrocarbons are detected on the surface of the site, due to a gas or oil leak from a truck or canister), a hydrocarbon separator can be installed that takes up and treats the water generally before contamination.

If pollutants are present, the rain water must be taken into account in the same way as process water (see « treatment for contaminated water »)
The impact on water and soil can be avoided by using retention tanks in senstive zones. They are used to control water flow and to guide water towards a treatment unit (see Module 9 « Transport and storeage : storing primary marterials and finished products »).

The 3 principle nuisances and pollution vectors are water, air and soil.
For each vector, different prevention, actions, and treatment means, exist in order to avoid that a pollution or nuisances flow towards the natural environment.
Each site is responsible of their own discharges: a polluted water flow issued from its parameter has to contained, treated and purified.
All pollutions and nuisances constated by the authorities, lead to potentially high fincanical costs in order to restore the area contaminated or victims harmed.
