HaloSan

The Ultimate Solution for Elimination of Iron, Manganese and Sulfate Reducing Bacteria in Groundwater Wells

HaloSan is a drinking water treatment chemical which is tested and certified by NSF International (see Background on NSF and the Drinking Water Additives Program) for disinfection and oxidation of bacteria for potable applications. This sanitizer is used to kill the naturally occurring bacteria in your well which cause odors, slimes, chemical resistant staining and clogging. HaloSan will kill any bacterium that does not have a spore in its life cycle.

• BioShield dispenses HaloSan, a well sanitizer, into the well water killing the iron and sulfate reducing bacteria.
• The BioShield product line is a treatment system for control of iron and sulfate reducing bacteria in water wells and associated equipment.
• BioShield eliminates iron and sulfate reducing bacteria problems in water wells preventing damage to associated equipment such as water treatment peripherals, irrigation systems and household appliances.
• BioShield prevents the formation of hydrogen sulfide gas by eliminating sulfate reducing bacteria.
• BioShield also enhances filter performance by preventing bacterial deposits of organic compounds and mineral hydroxides.

HaloSan, is NSF certified for disinfection of potable water supplies.

Well water is contaminated by a variety of bacteria, which feed upon the minerals in the water. The presence of as little as 0.1 mg/L iron in well water will encourage the growth of iron bacteria. These bacteria combine dissolved iron and manganese with oxygen and use it to form rust-colored deposits and slime which build up on well screens, pipes and plumbing fixtures resulting in odors, stained surfaces and clogged plumbing or irrigation systems. Layers of insoluble iron and organic material from the bacteria block screens and pipes reducing well yields and water pressure.

The number one reason for loss of production and abandonment of groundwater wells is biofouling, and the number one agent of biofouling is iron bacteria. Sessile organisms residing within biofilm possess a number of advantages over their free-swimming or planktonic counterparts, including increased resistance to adverse environmental conditions such as shocking and antibacterial agents. Biofilm development causes significant problems in the areas of public health, medicine, and industry. Accordingly, there has been a great deal of research to better understand biofilm development and to identify improved strategies for biofouling control.

Recent work in this area has focused on the role of cell-to-cell signaling within biofilm populations. It is now believed that many different types of bacteria are able to produce and respond to various hormone-like signal molecules. A particular subset of these molecules have been shown to be involved in biofilm formation and dispersal. HaloSan works by triggering the dispersion mechanism in biofilm bacteria. Once the bacteria are dispersed into the bulk fluid, they are easily eliminated by the sanitizer. HaloSan kills these bacteria and protects the well and everything the water touches from clogging, slimes, chemical resistant staining, and odors. HaloSan is the only chemical approved for use in the BioShield system. Traditional treatment methods work temporarily until clogged by the bacteria. The key to eliminating the problem is eliminating the bacteria at the source, in the well. The BioShield system is unique in this approach. HaloSan, is NSF certified for disinfection of potable water supplies.

Biofilm, the clog or buildup of organic and inorganic material within the well, encourages the growth of opportunistic and pathogenic bacteria including species such as H. pylori. Opportunistic bacteria, including Pseudomonas aeruginosa, can be harmful to people with immune compromise issues. Bacteria are not the only pathogens which can contaminate well systems; the list of potential pathogens in wells includes human viruses, pathogenic fungi, cyanobacteria and protozoa. E. coli is one of the most common well bacterial pathogens. Shallow wells under the influence of surface water are at greatest risk for contamination. The depth of the casing, not the depth of the well, is the key factor.
