TripleClear Force Field TM Filters
Legionella Removal Capability The electroabsorbtive properties of Force Field TM Filters allow it to remove a variety of contaminants from water including biological contaminants like Legionella pneumophila. Legionella pneumophila is a pathogenic bacterium commonly present in many residential, commercial and industrial systems such as cooling towers and hot water systems. It is transmitted as an aerosol and when aspirated by people having compromised immune systems can cause Legionnaires’ disease, a respiratory infection that causes pneumonia. Transmission of the Legionella pneumophila bacterium can be of great concern in hospitals and nursing homes where patients are more susceptible to infections. Applications Force Field TM Filters can be used as Point of Entry (POE) filters to reduce the amount of Legionella pneumophila entering a building. Point of Use (POU) filters can be designed and certified for use on showers or other water outlets. Such filters would be of particular interest in locations with immunocompromised people such as hospitals and nursing homes. Legionella outbreaks are also associated with cooling towers, car washes, and public fountains. Force Field TM Filters that remove Legionella pneumophila can be used in conjunction with other sanitization treatments to inhibit growth of the bacterium in all such water systems.

Force Field TM Filters Remove Lead in Water to Safe Levels
Lead is a toxic metal that is harmful to human health; there is NO safe level of Lead exposure. The primary route for lead poisoning in drinking water is not contamination of water by leaded fuels, old batteries or some hazardous waste site. The primary route is the distribution system used to carry water to your home, and even the plumbing within your home or building. This problem has become nearly epidemic in proportion due to the crumbling of our nation’s infrastructure. Prior to 2014, the legal definition for “lead free” was plumbing fixtures with a lead content of less than 8 %. In 2014, the term was redefined to include only fixtures with a lead content of 0.25% and newly installed fixtures must use the “lead free” materials–but this did not apply to fixtures currently in use! Therefore, if your building was constructed even as recently as 2014, your pipes could contain up to 32 times the allowable lead levels. Even worse, much of the municipal piping that is getting the water to your building is decades old and these pipes, in many cases, are comprised or have components that are largely comprised of lead. Today the issue is so widespread that at least 4 million households with children living in them are being exposed to high levels of lead. There are approximately half a million U.S. children ages 1-5 with blood lead levels above 5 micrograms per deciliter (g/dL), the reference level at which CDC recommends public health actions be initiated. Don’t take chances with your water. Upgrade to Triple Clear today!

PROTECT YOUR WATER SUPPLY FROM HARMFUL LEAD CONTAMINATION
Heavy metals in drinking water are a serious concern due to the adverse health effects that are associated with them. In order to determine if Triple Clear’s patented Force Field TM Filter media could address this issue, a panel of heavy metals was chosen for testing and analysis by independent third party labs. Based on customer requests and market trends for claims in drinking water filtration, it was decided that testing would be conducted for arsenic, barium, cadmium, chromium VI, copper, iron, lead, selenium and silver. The metals spike was purchased from CPI International and analysis of filtrate was provided by TestAmerica in Tampa, FL. Filtering of the spike through the media was carried out by BCS Laboratories in Gainesville, FL. The results of this testing show that both the Force Field TM Filter with silver, and the Force Field TM Filter with silver and carbon infused significantly reduced chromium VI, Copper, Iron, Lead and Selenium in water.

Independent testing* has proven that Force Field Filters remove greater than 99.9% of viruses (i.e. MS2 virus, norovirus), bacteria (i.e. E. coli, Pseudomonas and Legionella) and parasites (i.e. Giardia, Cryptosporidium). They also effectively remove a wide range of submicron particulates (i.e. sand and rust), heavy metals (i.e. Lead and Chromium VI), trace pharmaceuticals (i.e. BPH), and many other chemical residues. Unlike other submicron filters, Force Field Filters keep out the bad stuff, while keeping the good stuff in water. They also offer better flow, are less likely to clog, are easy to maintain and are completely chemical-free and environmentally-friendly. Force Field Filters are the ultimate choice for providing safe, clean and delicious water to your customers. When used as directed, our products are fail-safe.
Triple Clear’s Force Field Filter Technology triple filter purifies and protects water using mechanical filtering, carbon filtering and electroadsorptive technology (science originally developed for NASA). Water passes through the filter’s 400 layers of mechanical filtration, powdered carbon and a naturally occurring positively charged “force field” that, like a magnet, attracts, captures and kills negatively charged contaminants.

Building Reopening Checklist – Potable Water Systems
Buildings or floors that have been lightly occupied (<10% of normal occupancy) or unoccupied for more than 21 days should prepare the potable water systems for reopening 1 to 5 days prior to re-occupancy.
The CDC website for guidance for various building types is given here:
https://www.cdc.gov/coronavirus/2019-ncov/php/building-water-system.html
A checklist for reopening should include:
• Identifying team responsible for deciding when the building will be reopened
• Identifying the personnel responsible for reopening the building(s)
• Note that for large campus system with multiple buildings it is unreasonable to open all buildings simultaneously so a priority list for opening buildings should be developed by the team
• Each building should be inventoried for
Water filters •
•
Drinking fountains Flushing drinking fountain procedure should be in place (once filter is removed the fountain needs to be flushed - where is that water going – drain, bucket, hose?). New filters in stock • Ice Machines Lines should be flushed before putting new filter in place. • Other filters that may be present in kitchens • Water softeners
Overall Number of Fixtures • Bathrooms
•
Sensor based faucets (eye, pressure, etc) can be more difficult to flush – refer to faucet manual to identify how to override the sensor for flushing (for example) o Kohler (https://support.kohler.com/hc/en- us/articles/360008995074-Overriding-the-Sensor-on- Touchless-Faucets)

• Once an inventory has been completed put together a list for ordering equipment • Replacement filters for all systems • Drinking fountains • Ice Machines • Other • Thermometers or other devices for measuring hot water temperature • Buckets (for flushing drinking water fountains if no drain close by) • Order a chlorine testing kit such as
•
• https://www.hach.com/free-total-chlorine-test-strips-0-10-mg- l/product?id=7640211603&callback=pf
Note there are 50 tests per bottle.
• Work backwards to determine how long it will take to flush buildings and to staff properly
• All fixtures that may be used for consumption (drinking, eating, food prep) and bathing (showers, tubs, etc) need to be flushed until either • A free chlorine residual of 0.5 ppm has been achieved for potable cold water • OR • The water temperature at the location is consistent with delivery temperature of hot water (e.g. if hot water is made at 140 F and delivered at 120 F the water at the tap should be 120 F +/- 2 degrees F.
• The flushing process needs to be documented with: • Date/Time of flushing •
Final water quality (either free chlorine or temperature)
• It is unreasonable to flush a large building in a few hours. In order to have enough time it is a helpful exercise to do an estimate of time per floor/building.

• In this example the drinking fountains with fountains are the limiting factor – taking about 30 minutes per system to change (including flushing). • Note that these are just estimates for time.
Validate water system by testing for Legionella
• Perform a Legionella test on 2 to 3 cold water systems from different floors as well as the hot water system (tank) and distribution (showers). o This can be done by submitting samples to a local laboratory (like EMSL, or EMLab P&K) note that there is a 10 day turn around for this testing or it can be completed using an on-site test that returns results in 45 minutes. (https://www.spartanbio.com/products/environmental/legionella/) o Cost for analysis of Legionella should be between $100 to $200 per sample
EXAMPLE FLUSHING PROCEDURE
• Flushing process should be performed as follows:
o Start at one end of the floor of the building. o Working in one direction on the floor ▪
Open faucets in sinks to allow continuous flow of cold water or tempered water taking care not to overflow sink or drain • Record date/time starting and location ▪ Systems with dual (hot/cold) handles can both be opened ▪ Run Showers to allow continuous flow of hottest temperature available • Record date/time starting and location ▪ ONCE ALL SYSTEMS ARE FLOWING GO BACK TO INITIAL SYSTEM THAT WAS STARTED • For cold water test free chlorine o Minimum level should be 0.5 ppm as FAC o If level is 0.5 ppm FAC or greater the faucets in that room (e.g. bathroom with three sinks) can be shut off ▪ Only one fixture per “room” needs to be tested for chlorine - all fixtures must be flowing
▪ Record date, time, location and free chlorine level
o If level is not at 0.5 ppm FAC or greater then fixtures should continue to run to drain. Retest every 5 minutes until the free chlorine is above 0.5 ppm as FAC. ▪ Record date, time, location and free chlorine level
• For hot water test (hot water faucets, showers) o
Temperature should be measured as +/- 2 degrees of delivery temperatures set point. ▪
If delivery temperature is 120 F then faucet or shower should measure 118 to 122 F.
o If level is at +/- 2 degrees F of delivery temperature the sink or shower can be shut off. ▪ Only one fixture per “room” needs to be tested for temperature – all fixtures must be flowing ▪ Record date, time, location and temperature. o If temperature is lower than delivery temperature by more than 2 degrees, the fixtures should continue to run to drain. Retest every 5 minutes until the temperature is within 2 degrees of delivery temperature set point. ▪ Record date, time location and temperature.
o NOTE: It is important not to exceed the capacity of the hot water system or temperatures will not meet required delivery temperature.
▪ When all fixtures have been flushed, change filters on drinking fountains and flush fountains as well as any other filters that may be present (ice machines, etc). • These should be done last to minimize flushing of these systems – water that is in the piping will be freshly chlorinated and will minimize flushing times.
▪ Regenerate any water softeners if present.

Building Reopening Checklist – Non-Potable Water Systems
Buildings or floors that have been lightly occupied (<10% of normal occupancy) or unoccupied for more than 21 days should prepare the non-potable water systems for reopening 1 to 5 days prior to re-occupancy as well as develop a plan for operations during periods of lower overall usage.
The CDC website for guidance for various building types is given here:

A checklist for reopening should include:
• Identifying team responsible for deciding when the building will be reopened
• Identifying the personnel responsible for reopening the building(s)
Note that for large campus system with multiple buildings it is unreasonable to open all buildings simultaneously so a priority list for opening buildings should be developed by the team

Develop an operational strategy for circulating all cooling tower basins on a regular basis (every two to three days) while feeding biocides (chlorine, bromine, etc) and documenting residuals in towers.
For Example – Decorative Fountains
Develop an operational strategy for operating fountains on a regular basis (once per day for several hours) while feeding biocides (chlorine, bromine, etc) and documenting residuals in fountains
• Identify other water equipment that may be present such as • Water softeners • Carbon or Activated Charcoal filters •
Safety showers/eye washes – note that some sites may continue to test these on a regular basis so additional flushing may not be necessary
• Develop a time-line to regenerate water softeners 1 to 5 days prior to re-occupancy • Develop a time-line to backwash or replace carbon or activated charcoal filters 1 to 5 days prior to re-occupancy • Test/flush safety shower and eye washes prior to re-occupancy 1 to 5 days prior to re- occupancy
