Published in the April edition of the Waterwell Journal, this article looks at the problems caused by iron bacteria and iron oxide in wells and boreholes and how Boresaver, a specialist range of cleaning treatments, can solve those problems.

Mineral scale and bacterial slime contamination are becoming an increasing problem in groundwater bores in America. Iron bacteria and iron oxide deposits are estimated to affect about 40% of the world’s water bores and the rust-colored slime and solid encrustations cause reduction in the bore capacity, deterioration of water quality, motor burn out of the submersible pump, and encrustation on the pump, column, bore casing, screens and reticulation systems.  If left to accumulate the deposits can also cause severe maintenance problems and create unpleasant working conditions for operators.

Whether caused by naturally occurring bacteria or chemical infection, iron deposits or bacterial slime will eventually affect nearly everyone who sources water from groundwater aquifers.

Iron bacteria and iron oxide have been detected in many bores in Squaw Valley, California and Dan Roe from Roe Water Service has been dealing with the problem for years. “We see boreholes where the water runs red when the pump starts up, the sinks and toilets in the house are badly stained and pumps get so clogged up they don’t last more than a year. We’ve chlorinated before and the water was bad again in 2 weeks.”

BoreSaver Ultra C is a unique cleaning solution for iron oxide and bacterial slime contamination and is just one element of a phased treatment programme that has been successfully used across Australia and Europe and has now been brought to America by Laval Underground Surveys. Using a purpose built cable tool rig and a video inspection camera to record pre and post treatment results, service operators are able to gauge the correct BoreSaver treatment solution to use to achieve maximum results.

Tested and Certified by NSF International, BoreSaver Ultra C has been certified under ANSI/NSF Standard 60 for use in potable water supplies. A specially formulated proprietary blend of monohydrates and organic acids, Boreaver Ultra C successfully removes removes iron oxide deposits and iron bacteria. The formulation is based on leading independent research and the key component of BoreSaver Ultra C has been shown to be ten times more effective then other chemicals at removing iron oxide and iron bacteria.

Dan Roe in California was impressed with both the treatment results and the ability to see the results by using a downhole camera: “The camera visual was unbelievable.  In the first video, the walls of the well were covered with the iron bacteria.  We could only see little patches of granite through the brownish-red material.  In the second video, almost all the black and white granite was visible. But there was visual proof other than the video.  Roe had proof in the form of something othen than video. He had PVC pipe. In my experience, PVC pipe just never can be cleaned when it’s been in an Iron Bacteria hole.  We’ve tried bleaching, chlorinating, everything, but nothing has ever made those pipes look like they did when they came out of the BoreSaver Ultra C.  They almost looked brand new.”

Dan Roe is half way through his first phased treatment program but he’s already excited about the results: “We’ve chlorinated before and the water was bad again in 2 weeks.  I think that will be the real test for this hole.  I will continue to pump out the residue and IRB membrane. If this IRB is still out in one month we will be thrilled.”
