We have a serious case of groundwater contamination at Nisisioken Ogale, in Eleme LGA.
The pollution is due to the Nigerian National Petroleum Company product pipeline in proximity of which an 8 cm layer of refined oil was observed floating on the groundwater which serves the community wells.
Total petroleum hydrocarbons (TPH) are 30,000 for the adjacent soil.
How can we most efficiently and economically remove the oil from the already contaminated groundwater?
Wonderful concept. The "pays for itself" statement is a bit hard to swallow. Technology not new. the (ORI) oil recovery initiative was developed at The University of Texas at Austin. Research done in the 70's, testing and field trials in the 80's, went public in the early 90's. I do like the idea of recovery as it fits the ZERO Waste concept. Boils down to Recover or clean it. we call it remediation. Nature calls it bioremediation. using of oil eating microbes with zero waste and no residue. short view..... more options, more profit.
The adsorption bed filtration process is very efficient in this case. Contact us for advice, through the following contact: chcp1@hotmail.com or carloscatunda@uern.br
Kind regards.

I might be a bit late to this question. But I would suggest an organic Microbe that is completely safe for humans, fauna and flora. All you need is a dosing system and some aeration for the water and some on site soil remediation (can be done by manual labour and the right products).
I would suggest talking to someone from Tala Engineering Projects if this is a problem you still have, or for anyone reading through with the same problem. They are based in South Africa and have a lot of expertise in solving problems like this.
We have plans for short term and long term water management. In regard to Nigeria products must pass DPR testing without microbes. We are culturing natural oil eating microbes from the areas that we are working.
The only solution is to supply you with drinking water elsewhere. As Helen says it is an important continual deep pollution. At first you have to go to the source of pollution and remove it!!!!!
Then allow time to clean up this pollution (a few years)
Contaminated water is for ongtemps and of course micro organisms will never manage to purify this pollution
la seule solution c'est de vous approvisionner en eau potable par ailleurs. comme le dit Helen il s'agit d'une pollution continuelle profonde importante. Dans un premier temps il faut aller à la source de la pollution et la supprimer!!!!!
Ensuite laisser au temps le temps de nettoyer cette pollution ( quelques années)
l'eau contaminée l'est pour l'ongtemps et bien entendu les micros organismes n'arriveront jamais à épurer cette pollution
A lot of marketing seems to be posted here. One thing for sure man and machines will never be able to do the job that nature has evolved to do over a few billion years. I believe asking many questions of artificial cleanups is in order. Get cost estimates on each offer. See if any can compete with nature. Good luck.
There are many excellent responses below. On tother additional consideration I would suggest (which you may already have in place), is that you determine the extent to which oil may travel within the aquifer. In my dealings with ground contamination where groundwater sources have been or have the potential to be contaminated, resolution of the problem is not a simple nor short-term solution . I have found by setting up your internal and external boundaries with appropriate monitoring and controls is always a benefit.
Helen, We are using several approaches, Our site is under 3 feet of water. First we are fencing the area with a membrane fence that will let the water through but not he oil. In this double fences paremeter we will also be using OspreySorb a 30:1 nontoxic cellulose sorbent. then on site we are skimming, the using an incredible product that has incredible results in 30 days, even heavy metals. We will be treating to 60M aquifer. Within the water tables we are using nanobubbling system with our solution!
Next week we will be testing to the aquifer level and will have so much more information.

Mary, you will need some free product recovery and then remediation of the contaminated groundwater and soil. It might be worthwhile contacting Verde Environmental. They are already operating in Nigeria.
Hello, we have successfully cleaned-up in-situ, dozens of sites contaminated with hydrocarbons using electro-bioremediation. But it is essential that you always start with removing the free product. This can be done using skimmers or a device we specifically developed for this purpose. If you want more information just let me know
I understand that OilSolutions International has oilclean up products as microencapsulated spongy or rubbery and resinous materials that scavenge oil from water,so that it can be easily scummed off.
Microencapsulated adsorben sponges have high oil remediation efficiencies,and ease of removal combined with application and absorption effectiveness
We are using skimmers, bioremediation with the only bi-product from oil remediation is water, CO2, and Humus. We also use the highest sorbent in the market called OspreySorb, non toxic, with a 30:1 sorption rate sorbent and creates basically no ash and burns at 7000 BTU's.
Dear Suresh sir: very keen to learn it more. I am in Gujarat state of India and working with ultra poor farmers. few days back in peak summer in one district of Gujarat there was contamination of aquifer due to oil pipe line puncture. It was difficult situation. if the remedial process is cost effective then we can try to popularize within farmers. regards Biplab Paul T; @BHUNGROO Ph +919825506900
We have the gold standard in hydrocarbon remediation products called OspreyMix, a DPR certified product, 100% green technology. In Nigeria in 21 days reduced the TPH by 99.8% in the water and 95.6% in the soil and removed all of the BTEX.
Our company uses a proprietary application of a biological accelerator and peat moss with an excellent success record and a much lower cost then conventional methods. We are eco-friendly and US EPA approved for aquatic remediation.
Mary ... Our company has been very successful in removing petrocarbons, oil, diesel and gasoline from water in Europe quite recently. We have used our product to clean small oil spills in QATAR in the past.
As some in this forum have said, microbiological remediation is the new, inexpensive way to solve your problem.
We would be more than happy to go over in detail with you the protocols used recently in Europe.
Using the Bioremediation modern technology all you really need to do is apply the ARCHAEA microbial species at a selected point of entry and let them do their natural biological function. If you remember there are many international cleanups by the ARCHAEA with no residue and extremely low cost to do so. All of the 1950,s technologies do work. Just a choice of low cost and efficiency. (go to you tube Megaborg oil spill 1990. ).
Mary; Someone is pulling a scam. Chemical intervention will not be effective. Only microbial intervention will work. If there is a portion of their infrastructure that will actually inspect each powdered product then I would recommend a very small microbe that is 1/10,000 the size of the smallest bacteria. The RNA group name for this species is Archaea. The only way you can tell they are there is with a scanning electron microscope. That will only show millions together but never able to see a single one. South Africa uses this microbe more than any other country. The USDA/NOP has approved it as 100% organic and the W.T.O. has authorized its use because of its natural ability to eliminate all pathogens and toxins. When it is shipped into any country with corrupt officials it is identified by its ISO number and as a "Healing Clay" Which also happens to be true. I am in Texas. If you want an expert closer to you Jean Marius from France I believe is the most knowledgeable.
Bonjour Jean. Como se va. Excellent comment. Few in this industry comprehend the value of microbes in our earths circle of life. What we call "cleaning" microbes call food. Not all people like the same foods and it is the same in nature. Microbiologist discover a new microbe, determine its' parameters then add it to their data base for to be learned later what they are used for by nature.
Your analysis is spot on. When some new technology comes along some are eager to learn and others stick with what they know best regardless of the efficiency and cost of it. I do not pretend to know your background and training. But I have read many of your comments and the #1 characteristic is your passion to do good things for all using your God given talents. If you have not already done so allow me to introduce the Archaea microbe. details another comment thread. Classification is an RNA microbe. Has NO DNA structure. parameters are: temp range 28 F to 427 F, ph. range is 5.5 to 10.0, moisture requirements suspense is 2% to 10%, activation is at 10% moisture, best activity level is 50%, can still function at 99% moisture. It is aerobic and because many species are from volcanos they con fully function at 1ppm of O2. (microaerophilic). DNA bacteria and fungi do not have the genetic code for reducing compounds into their elemental state. Just less complex compounds. Archaea does reduce all compounds into their elemental/nutritional state. This does include the chelation of all metals.(heavy metals/nutrients). Pleasure to share cutting edge technology.
