INTRODUCTION
The ongoing growth of human population in the world and its
associated impacts, mean that the need for environmental restoration
has become increasingly clear. Environmental restoration is a term
common in the citizens’ environmental movement. It is closely allied
with ecological restoration and environmental rehabilitation.
APPROACHES
Environmental restoration involves many different approaches and
technologies depending on the requirements of the situation.
• Heavy equipments like cranes, graders, bulldozers or excavators.
• Hand processes like the planting of trees and other vegetation.
• High-tech processes such as those applied in the careful
environmental control required in fish-hatchery procedures.
• Computer-based mapping.
In some situations, environmental restorative work is handled entirely
by professionals working with skilled operators and technicians.
GOALS
Goals of the program shall include the following:
1. The identification, research and cleanup of contamination from a
hazardous substance or pollutant or contaminant.
2. Correction of other environmental damage which creates an
imminent and substantial endangerment to the public health or
welfare or to the environment.
3. Demolition and removal of unsafe buildings and structures.
OVERVIEW
The project scope includes;
• Characterizing the nature and extent of contamination
in soil, groundwater, surface water/sediment, plants,
and animals.
• Selecting and implement cleanup actions for soil and
groundwater that are protective of human health and
the environment.
• Maintain protection over time.
• Minimize untreated waste.
CONCLUSION
Whether we like it or not or can confront it
or not we all need to heed the warning
signs of an impending environmental 9/11.
There is still time but experts give us only
about a decade to reverse the tides. This
is our wake up call . With the help of
environmental restoration we can try to
ensure a better planet for our future
generations.
RESTORATION PROJECT : HURRICANE
KATRINA
AFTERMATH
Hurricane Katrina, the 11th named storm and 5th
Hurricane of 2005 Atlantic Hurricane season
caused severe environmental degradation
throughout the coastal region.
-Destruction along Gulf Coast from Central
Florida to Texas.
-Failure of levee system in Orleans.
-Carbon monoxide poisoning.
-Oil and chemical spills in hazardous sites.
- Releasing toxic materials.
-Contaminating groundwater and drinking water.
PLANNING
The restoration planning for Hurricane Katrina
based on 3 types of restoration;
1.HABITAT RESTORATION:
NOAA Fisheries Services planned large scale
multimillion dollar habitat restoration.
2.WETLAND RESTORATION:
NOAA and its partners planned to asses the
island and wetland restoration
.
3.RESTORATION FROM CHEMICAL WASTES:
OR&R responded to damage assessment to oil
and chemical spills.
PROCESS
For different restoration treatments the measures
taken were different.
-NOAA funded nearly 40 on ground habitat
restoration in Louisiana and Mississippi.
-NOAA also assisted in natural restoration of
shoreline by oyster reefs and wetland planting.
-OR&R’s mission was to minimise harm and to
develop best practice of controlling oil spills in
hazardous waste sites.
