Is the Water Safe at Your Favorite Restaurant? 

There has been a lot of controversy and discussion regarding post mix vending machines, (dispensers that mix flavored syrup with carbonated water), that are used in most fast food restaurants and the majority of convenience stores today. The post mix dispenser system is a combination of equipment and materials such as: water from the building supply, pressurized CO2 cylinders, a carbonator tank, a high-pressure water pump, containers of flavored syrups, usually bags in boxes, syrup pumps, and the dispenser console where the carbonated water and syrups are mixed. This all seems simple enough; however, the problem is the CO2 and water if it contacts copper water lines

Sunlight Plus Lime Juice Makes Drinking Water Safer

Looking for an inexpensive and effective way to quickly improve the quality of your drinking water? According to a team of researchers from the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins School of Medicine, sunlight and a twist of lime might do the trick. Researchers found that adding limejuice to water that is treated with a solar disinfection method removed detectable levels of harmful bacteria such as Escherichia coli (E. coli) significantly faster than solar disinfection alone. The results are featured in the April 2012 issue of American Journal of Tropical Medicine and Hygiene.

Happy New Year!

The San Antonio Chapter of the American Backflow Prevention Association was able to hold eight monthly meetings last year in spite of COVID-19. We used many of the techniques that BAC-FLO Unlimited initiated in their classes, to provide a safe environment for the members who attended our meetings, which included limiting the number of members attending, social distancing, checking temperatures, and the use of sanitizers. We will continue with those procedures and continue to provide box lunches to limit the handling of the food presented to the members. It is important for members to be mindful and not sign up for a meeting if you are not sure you will be able to attend, because that prevents someone else from attending. We do realize that sometimes last minute emergencies do happen. We were able to accommodate everyone who signed up for a meeting in 2021. The couple of members who were on the “Wait List” were able to attend.
