Que ce soit pour l\u2019achat d\u2019un terrain ou d\u2019une propri\u00e9t\u00e9 immobili\u00e8re, l\u2019\u00e9valuation environnementale est un param\u00e8tre important \u00e0 consid\u00e9rer avant l\u2019acquisition. Cette \u00e9tude de sols permet de d\u00e9terminer le degr\u00e9 de contamination et de la d\u00e9tecter en amont afin d\u2019\u00e9viter de nombreux probl\u00e8mes sur le long terme.
Les polluants susceptibles de contaminer le sol et les eaux souterraines sont les :<\/p>\n\n\n\n
\u2013 hydrocarbures p\u00e9troliers
\u2013 toxiques organiques
\u2013 m\u00e9taux et substances radioactives
\u2013 pesticides
\u2013 autres.<\/p>\n\n\n\n
Pour v\u00e9rifier l\u2019\u00e9tat environnemental d\u2019un terrain, l\u2019\u00e9tude documentaire est
recommand\u00e9e afin de lister les activit\u00e9s ant\u00e9rieures susceptibles de le contaminer. Si
l\u2019\u00e9tude de l\u2019historique du site r\u00e9v\u00e8le des indices d\u2019une probabilit\u00e9 de contamination,
l\u2019\u00e9tape suivante consiste \u00e0 pr\u00e9lever des \u00e9chantillons de sol et de les analyser en
laboratoire.
Les r\u00e9sultats d\u2019analyse des \u00e9chantillons de sol en laboratoire d\u00e9termineront le degr\u00e9 de
contamination et le type de contaminants. Ces donn\u00e9es techniques permettent :
\u2013 d\u2019\u00e9valuer l\u2019ampleur du probl\u00e8me, les risques pour l\u2019environnement
\u2013 d\u2019estimer le co\u00fbt d\u2019une d\u00e9contamination, d\u00e9terminer les mesures correctrices \u00e0
r\u00e9aliser
\u2013 d\u2019envisager les options qui s\u2019offrent aux acheteurs potentiels, aider \u00e0 la
d\u00e9cision : acheter ou annuler l\u2019offre d\u2019achat.
Le risque de contamination est plus \u00e9lev\u00e9 lorsque des activit\u00e9s industrielles (garage
m\u00e9canique, station-service, usine m\u00e9tallurgique) s\u2019y sont d\u00e9roul\u00e9es dans le pass\u00e9. En
ville, les anciens terrains industriels convertis en zones r\u00e9sidentielles sont les plus
concern\u00e9s par des \u00e9tudes de sol. En revanche, pour les terrains r\u00e9sidentiels, la
d\u00e9gradation des r\u00e9servoirs d\u2019huile de chauffage (enfouis ou hors-sol) entra\u00eene des fuites
de substances polluantes pour le sol et qui sont g\u00e9n\u00e9ralement toxiques pour la sant\u00e9.<\/p>\n\n\n\n
Lorsqu\u2019une contamination est d\u00e9couverte, il est difficile de prouver qui est le
responsable (les acheteurs et anciens vendeurs se renvoient la responsabilit\u00e9).
C\u2019est la raison pour laquelle, les institutions financi\u00e8res exigent de plus en plus aupr\u00e8s
de leurs clients, d\u2019effectuer des \u00e9valuations environnementales avant d\u2019accorder un
pr\u00eat hypoth\u00e9caire. Cette d\u00e9marche initi\u00e9e par les institutions financi\u00e8res (pr\u00eateurs) leur
permet de s\u2019assurer que la valeur de la propri\u00e9t\u00e9 et\/ou du terrain, \u00e9quivaut au montant
de l\u2019offre d\u2019achat.
Dans le cas d\u2019une contamination av\u00e9r\u00e9e, les propri\u00e9taires d\u2019un terrain sont
confront\u00e9s \u00e0 des proc\u00e9dures judiciaires en cascade, \u00e0 des d\u00e9marches fastidieuses aupr\u00e8s
des assureurs, \u00e0 d\u00e9montrer l\u2019existence d\u2019un vice cach\u00e9, et enfin \u00e0 payer une somme
on\u00e9reuse pour d\u00e9contaminer. Toutes ces \u00e9tapes entra\u00eenent des co\u00fbts financiers \u00e9lev\u00e9s,
une perte de la valeur immobili\u00e8re de la propri\u00e9t\u00e9, du temps et de l\u2019\u00e9nergie pour
solutionner le probl\u00e8me.
Afin d\u2019\u00e9viter toute mauvaise surprise, mieux vaut anticiper. L\u2019achat d\u2019un terrain
demeure un acte majeur loin d\u2019\u00eatre anodin. L\u2019\u00e9tude de sol n\u2019est pas une futilit\u00e9, elle
prot\u00e8ge le futur acheteur de nombreux soucis.<\/p>\n\n\n\n
