Temporary Change in Water Treatment Method

By | August 29, 2017

Earlier today ‘Juline803′ asked, “The local paper today said my water company is temporarily changing the water treatment method from chloramines to free chlorine and that we should not worry if our water smells like chlorine.  How much chlorine is too much and what is the difference between chloramines and free chlorine?  Why the change in treatment types?  Is there a problem they’re not telling us?”

Thank you, Juline, for the inquiry.  We will begin our response by saying that the change in water treatment methods does not mean your water treatment company has made the decision because they have something to hide.  Water plants that use chloramines as the primary disinfection method routinely must perform a free-chlorine conversion (also known as a ‘burn’) as an added level of disinfection.

Municipalities will typically also flush water lines to clear them of any sediment that may have accumulated since the last flushing and force water in low use or low pressure areas out of the system.

How much chlorine is too much chlorine?

The United States Environmental Protection Agency has set the maximum allowable limit for both free and total chlorine at 4ppm.  You can use a product such as the 
WaterWorks 2 Free & Total Chlorine Test Strip to quickly and easily determine how much free chlorine and total chlorine your water contains.

What is the difference between free chlorine and total chlorine?

Simply put, the total chlorine concentration in a water sample includes all available free chlorine plus all the chlorine that has already oxidized (acted on) contaminants in the water and become combined chlorine (often referred to as chloramines and/or monochloramines).

Free (available) chlorine refers to the concentration of chlorine molecules residing a water sample that have not, yet, oxidized contaminants.

(Total Chlorine) – (Free Chlorine) = Combined Chlorine

For pool water you can use a test strip like the Pool Check 6-Way to determine the free and total chlorine concentrations of a sample.

For drinking water you can use test strips like SenSafe Free Chlorine Water Check to determine the free chlorine concentration of a water sample and SenSafe Total Chlorine Water Check to determine the total chlorine concentration of a water sample.

OR, for an even easier test procedure, you can use the WaterWorks 2 Free & Total Chlorine Test Strip which tests for both free and total chlorine at the same time.

SenSafe Free Chlorine Water Check (0 - 6ppm)
SenSafe Free Chlorine Water Check
Detects 0 – 6 ppm

SenSafe Total Chlorine Test Strips (0 - 10ppm)
SenSafe Total Chlorine Test Strips
Detect 0 – 10ppm

Filter to Remove PFOA’s

By | August 29, 2017

With all the news stories out there regarding PFOA’s and related compounds turning up in drinking water all over the country we knew it would not take long for the following question:  ‘DanD’ wrote,
“Water in our town has pfoas in according to a local news station’s report.  What kind of filter removes PFOA’s?”

At this time we carry an undercounter water filter from Propur™- the 
FS10 UnderCounter Water Filter – that has successfully tested to the NSF Perfluorinated Organic Acids reduction test for spiked water.

How Well Does the Propur™ FS10 Perform?

Read the independent laboratory test results for removal/reduction of…

Additional Information About the Propur™ FS10

Why You Should Choose the Propur™ FS10

The FS10 FULL SPECTRUM™ filter is specifically designed for unsurpassed performance and maximum contaminant reduction. Independent lab reports (links to reports are listed above) show the ProMax™ FULL SPECTRUM™ reduces/removes a broad range of over 220 contaminants including VOC’s, lead, fluoride, heavy metals, pesticides, SVC’s, disinfectants, inorganic non-metallics, herbicides, pharmaceuticals, PFOA, PFOS and micro-organisms.

FS10 FULL SPECTRUM™ filter also contains Catalytic GAC (granular activated carbon) with enhanced carbon media to help improve your water’s taste and odor.

Testing for THM’s (Trihalomethanes) & Water Filters for THM’s

By | March 28, 2017

We recently heard from ‘Brad’ who emailed, “Looking to test for THMs.”

Thank you, Brad, for the inquiry.  At this point we know of no at-home water test kit exists that test for THM’s (trihalomethanes) or other DBP’s (disinfection byproducts).  Testing for those sorts of substances/compounds requires laboratory techniques and equipment.

With that said, companies like National Testing Laboratories offer mail-in water testing services that include tests for THM’s. The most basic one we know of is called “Watercheck City-Check Basic” and you can read more about it in the Water Test Kit Store.

Results of testing carried out by National Testing Laboratories typically get emailed to customers about 10 business days after the lab receives samples for analysis.

What are THM’s?

The term trihalomethanes describes a class of compounds in the disinfection byproduct family which get created when a disinfectant (example: chlorine in the form of hypochlorous acid) interacts with and/or neutralizes organic contaminants in water.

Scientists and health officials have determined that consuming water with elevated levels of THM’s poses a threat to human health and therefore the EPA regulates the amount of THM’s that public water supplies may possess.  If a water system’s internal testing reveals higher than allowed levels of THM’s the water system must immediately remedy the situation and in most cases must also report the failed tests to its customers within a specified period of time.

Filtering THM’s Out of Drinking Water

Can home water filters remove or drastically reduce THM’s in drinking water?  Yes, some do have that ability.  As an example, several of the home water filters in the Multipure product line have been
tested according to NSF/ANSI Standard 53 for the reduction of a number of potentially harmful drinking water contaminants including THM’s.

During that testing Multipure’s Drinking Water Systems’ AquaversaAquaperform and Aquadome water filter systems effectively reduced concentrations of unwanted contaminants to less than
or equal to the permissible contaminant limits for filtered water leaving the systems.

If you’d like to see the full list of potential drinking water contaminants Multipure filters remove or reduce, you can view that information here.
