3. PETROLEUM HYDROCARBON
GOOD
BAD
AS SOURCE OF ENERGY
AS AN ECONOMIC RESOURCE
WHEN SPILLED ON LAND , WATER OR AIR

4. ENVIRONMENTAL REMEDIATION
THIS IS A PROCESS TO REDEEM OR REMEDY THE ENVIRONMENT FROM ANY SET BACK

5. APPROACHES TO ENVIRONMENTAL REMEDIATION
PHYSICAL METHODS
CHEMICAL METHODS
BIO-TECH METHODS

6. PHYSICAL METHODS SCOOPING OF HYDROCARBON SPILL EXCAVATION OF TOP SOIL
USING FLOATERS TO ABSORB SPILLED OIL ON WATER

7. CHEMICAL METHODS APPLICATION OF IN-ORGANIC FERTILIZERS
DIRECT INTRODUCTION OF NITROGEN AND/OR PHOSPHOROUS INTO THE SOIL (BIOVENTING)
ADDITION OF ANY IN-ORGANIC NEUTRALIZING AGENT INTO THE ENVIRONMENT
BIO PILES

8. BIO-TECH (BIO-REMEDIATION) METHOD
PHYTOREMEDIATION
MICROBIAL REMEDIATION
COMPOSTING
ENGINEERED TREATED CELLS
ETC

9. THE APPROACHES CAN BE
IN - SITU
OUT - SITU

10. GENERAL PRINCIPLES OF IN-SITU BIOREMEDIATION
THAT BACTERIA OCCUR BY NATURE
THAT THEY ADAPT TO THEIR ENVIRONMENTS
MIROBIAL ACTIVITIES CAN BE LIMITED BY ENVIRONMENT/NUTRIENTS
THAT WHEN SUCH LIMITS ARE REMOVED MICROBE COMMUNITY CAN DEGRADESUBSTRATES
AEROBIC BIODEGRADATION IS PREFFERED BECAUSE ITS FASTER AND COMPLETES DEGGRADATION
SOME MICROBES MULTIPLY FASTER WHEN IN CONTACT WITH HYDROCARBON CONTAMINANTS
THAT MICROBIAL TRANSFORMATION CAN LEAD TO TOXIC WASTE
THAT SELECTED PLANTS CAN REMEDIATE A CONTAMINATED ENVIRONMENT

11. EXAMPLES OF BIOREMEDIATION MICROBES
NATURAL BACTERIA ( FLAVOBACTERIUM SPP,PSEUDOMONAS SPP
MIXED BACTERIA (CONSORTA, ANEROBES)
GENETICALLY ENGINEERED MICROBES
FUNGI

12. PHYTOREMEDIATION PHYTOTRASFORMATION PHYTODEGRADATION
PHYTOSTABILIZATION
PHYTOSTIMULATION
PHYTOVOLATILIZATION
RHIZOFILTRATION
PHYTOEXTRACTION

13. LOCAL EXAMPLESOF SUCH PLANTS
PIG WEED (BOEHOVIA DIFFUSA)
HEMP (CANNABIS SATIVA)
LEGUMES
TOBACCO
SUNFLOWER
CORN
GRASSES
HYCINTH
ETC

14. PREVIOUS EXPERIENCES IN ENVIRONMENTAL REMEDIATION
JONES CREEK SPILL (SPDC-W)
SAGHARA OIL-FIELD (SPDC-W)
JESSE (DEVIN REMEDIATION)

15. OUR USUAL PRELIMINARY PROCEDURES
STUDY THE HISTORY OF THE ENVIRONMENT
IS THEIR ACCLIMATED POPULATION OF DESIRABLE MICRORGANISMS
IS THERE A REDUCING ZONE (BACTERIA ACTIVITY)
WHAT IS THE HYDROLOGY
DISTRIBUTION OF CONTAMINANTS(VERTICAL AND HORIZONTAL)
CONCENTRATION OF CONTAMINANT
LITHOLOGY OF THE SUBSURFACE

16. WHAT ARE BIOSURFACTANTS
THEY STIMULATE OR ENCOURAGE THE GROWTH OF BIOREMEDIATION MICROBES AROUND A HYDROCARBON CONTAMINANT

17. EXAMPLES OF BIOSURFACTANTS
BIO-BOOM
PRP WAX
