PathShield™ Antimicrobial


PathShield™ Antimicrobial Filter Media

Removal of Waterborne Bacteria

The EPA website states, “In 1996, over 2,500 beaches in the United States were posted with warnings or closed for at least one day because the water was contaminated. Today, many beaches are either not monitored well or not monitored at all, so Americans continue to face risks of illness from swimming and other activities in coastal areas, lakes, and rivers that contain disease-causing microbes. By carrying out the Clean Beaches Plan, we are helping state, tribal, and local beach managers strengthen their programs. A strategy for reducing the risks of infection to people who use our recreational waters, the Plan recognizes that beach managers need tools that allow for local and regional differences in pollution sources and climate. The Clean Beaches Plan describes what we plan to do over the next couple of years to achieve two major goals: promote recreational water quality programs nationwide and create scientific improvements that support timely recreational water monitoring and reporting.” Click here to learn more on the 2004 Clean Beach Plan.

Technology Description

PathShield™ effectively reduces coliform bacteria without releasing, discharging, or leaching any antimicrobial agents, chemicals or heavy metals. PathShield™ kills coliform bacteria as the organisms physically move over the hostile surface of filter media granules (Figure 1). Efficacy is achieved at high filtration loading rates up to 20 gallons per minute per square foot (gpm/ft²). PathShield™ filter media is not consumed, requires no power source, has no moving parts, is non-corrosive, and is unaffected by seasonal temperature changes

Laboratory Testing
A number of independent efficacy tests were performed by a NELAP accredited laboratory certified to perform E. coli plate counts. Various influent surface area loading rates and test cartridges simulated over 400,000 gallons of water passing through 24 cubic feet of PathShield™ media on an annual basis.

Refer to the literature below where you will find summaries of the results of the laboratory simulations. E. coli concentrations ranged from 150 to 36,000 colony forming units per 100 milliliters (cfu/100 ml) while loading rates ranged from 9 to 118 gpm/ft². Efficacies of >99.9% or log three reductions, were achieved for these eight simulations. Additional independent long term laboratory efficacy challenges against E. coli were performed using 15 separate quality control PathShield™ filter media samples.

Field Testing
A series of independent filed verification tests were performed by university researchers using PathShield™ filter media within a full scale commercially available stormwater catch basin insert at an ultra urban location in Los Angeles, California.



Toxicity Testing
Comprehensive studies have been confirmed through the PathShield™ EPA registration that the media does not leach any antimicrobial agents, chemicals, or heavy metals and the effluent treated water is non-toxic.

Conclusions and Benefits
PathShield™ Antimicrobial Filter Media demonstrates superior performance for the removal of coliform bacteria in a variety of treatment applications including municipal waste water and stormwater runoff. EPA registration of PathShield™ confirms that coliform bacteria are physically killed as they pass through the media.

Significant operational and environmental benefits can be realized through the use of PathShield™ filter media including:

  • EPA registered antimicrobial filter media
• Media does not discharge, release or leach any antimicrobial agents
• Long term and high level of performance
• Does not rely on physical trapping
• No external power source or moving parts
• Media is non-corrosive and is not consumed
• Unaffected by seasonal temperature changes

CrystalStream helps Educate our future about Stormwater Treatment

ELIZABETHTON —CrystalStream Technologies was proud to be invited once again to contribute time to the education of future leaders at this years Elizabethton/Carter County Conservation Camp. One of the great things about the camp is there are so many things to do and to learn; the children hardly have time to be bored.  There also were stations where the children learned about soil erosion by actually getting to play in the dirt. Don Billingsley with CrystalStream Technologies took time to teach the students about stormwater management and how important it is to remove sediment from our stormwater runoff.

The camp is sponsored by the Elizabethton/Carter County Chamber of Commerce.

Below are some pictures of this exciting event.

Stormwater Runoff provides plant food

Today, more people are thinking about stormwater runoff as a resource.  In my opinion, we are missing an important opportunity with a readily available resource.  Everyone knows that stormwater runoff contains nutrients.  Some jurisdictions are so concerned with these nutrients that they base their water quality plan approvals solely on the removal of the metallic element phosphorus.

It is time we started to plant stormwater vegetable gardens in our BMPs to solve the nutrient problem while providing food for people and farm animals.

The justification for many “bio-based” best management practices (BMPs) is the fact that they can take up nutrients like phosphorus and nitrogen, thus “removing” them from the runoff.  This is, in fact, true, if the plants that take up the nutrients are physically removed from the BMP before they pass on to that great garden in the sky.  If they are allowed to expire, they will decompose and then pass on their carefully gathered nutrients to some other lucky plant or animal.  Even though our atmosphere is mostly nitrogen, this gaseous form of the element needs to be “fixed” to be available to plants.  This is mostly accomplished by bacteria in the soil.  This process, while important, is not the major source of nitrogen for plants.  Most of the available nitrogen comes from decomposers (fungi and bacteria) that break down existing organic material.  Regardless of the process, it is important to note that stormwater carries a ready source of useable nitrogen and phosphorus that we are literally wasting.  Using a biotic BMP is a handy way to get nutrients out of the water and back into plants where they belong. As an added bonus, other nasty metals and chemicals have been shown to be taken up by plants as well as phosphorus and nitrogen.

Now it might seem like putting metals and other pollution into the food chain via vegetable gardens is a bad idea, but if we confine these dangerous materials to a known location (people and farm animals), we can keep track of them and keep them from escaping to our lakes and rivers.  As it stands today, with practically no one actually removing plants (or anything else for that matter) from BMPs, all of the material taken up by the biological processes will eventually be released back into the water as the organic material dies and decomposes.  This material then proceeds downstream to parts unknown, where it is sure to be taken up by another plant or animal.  It now becomes impossible to know where the metals and chemicals might reside.  Some innocent child might catch a perch in the lake, and consume it, not knowing that the chemicals contained within might have come from an approved BMP.

If growing and eating vegetables laced with chemicals taken up from a bio-based BMP makes no sense, does it make any more sense to place these same chemicals into the food chain with no thought of where they might end up?  It does not, and I say we plant the veggie gardens and be sure the pollution does not go any further.  The gunk stops here. Bon appetit!
