 Background
Outdoor storage facilities for wood poles treated with pentachlorophenol
(PCP) can generate significant soil and groundwater contamination
by leachate due to exposure to heat and precipitation. Biogenie’s
mandate was to restore a total of 16 storage sites,
as well as design and manage the construction of new storage sites
equipped with efficient, economical and low maintenance environmental
protection systems.
Other
logistical challenges stemmed from site location (residential area),
permanent structures, power lines and strong odours emanating from
the contaminants.
Solution
The PCP-contaminated soils were treated with Biogenie’s ex situ Biopile process. The environmental protection systems consisted
of impermeable recovery basins that directed the PCP-contaminated
storm water to a physico-chemical treatment unit. Once separated
from the water, the oily solvent was sent for disposal and, in accordance
with negotiated criteria with different municipalities, the water
was discharged into the sewage system.
Services
- Characterization
study to determine the extent and degree of soil and groundwater
contamination on the existing storage sites;
-
Remediation
of commercial and industrial storage sites, notably the
biological treatment of 6,000 tons of PCP-Contaminated
soil.
- Design
of environmental protection systems for soil and groundwater assuring
the recovery of PCP-contaminated water utilizing a physico-chemical
treatment process;
- Design,
preparation of plans and preliminary estimates, as well as documents
pertaining to proposals for the construction of environmental
protection systems;
- Secure certificates of approval from the Ministry of Environment
for the development of
new storage sites equipped with environmental protection systems;
- Management
and supervision throughout the construction of new storage sites;
- Environmental
monitoring (sampling of recovered water, treated water and groundwater).
