KIRSTEN JOHNSON, THANKS VERY MUCH.

>> THANK YOU FOR HAVING ME.

>> TURNING TO THE ENVIRONMENT, AT LEAST 45% OF TAP WATER CONTAINS THE CANCER-CAUSING FOREVER CHEMICALS KNOWN AS P.F.A.S., ACCORDING TO A RECENTLY NATIONWIDE STUDY FROM THE U.S. GEOLOGICAL SURVEY, VARYING GREATLY DEPENDING ON WHERE YOU LIVE.

AS RESEARCH INTO P.F.A.S.

EXPANDS, SO DOES THE REACH OF WHERE IT IT IS FOUND IN EVERYDAY LIVES.

FOR MORE ON HOW TO MITIGATE EXPOSURE TO THESE CHEMICALS IN YOUR OWN HOME, WE TURN TO JOE GRANDE, WATER QUALITY MANAGER FOR THE MADISON WATER UTILITY.

THANK YOU FOR BEING WITH US.

>> GLAD TO BE HERE.

>> SO WISCONSIN CLEARLY HAS P.F.A.S.

IN ALL CORNERS AND IN SOME PLACE, THERE ARE DEFINITE P.F.A.S.

HOT SPOTS, BUT HOW DOES SOMEONE KNOW IF THEY HAVE EXPOSURE TO P.F.A.S.

IN THEIR DRINKING WATER AND WHETHER IT'S ENOUGH TO WORRY ABOUT?

>> SURE.

SO REALLY DEPENDS ON WHAT THE SOURCE IS OF THEIR DRINKING WATER, WHETHER THEY ARE SERVED BY A PUBLIC UTILITY OR WHETHER THEY HAVE A PRIVATE WELL AND IT'S THEIR OWN INDIVIDUAL RESPONSIBILITY.

SO IF THEY'RE ON A PUBLIC WATER SYSTEM OR A PUBLIC UTILITY, THEY SHOULD REACH OUT TO THEIR UTILITY.

MAYBE THEY RECEIVE INFORMATION FROM THEIR CONSUMER CONFIDENCE REPORT OR THEIR ANNUAL WATER QUALITY REPORT AND IT REPORTS ON THAT.

SO THE LARGEST UTILITIES IN THE STATE WOULD HAVE DONE THEIR INITIAL TESTING LATE IN 2022, SO THAT SHOULD BE REPORTED ON THEIR CURRENT CONSUMER CONFIDENCE REPORT.

SOME OF THE SMALLER UTILITIES ACROSS THE STATE ARE CURRENTLY DOING THAT TESTING, SO THEY MIGHT NOT HAVE THOSE RESULTS ALREADY REPORTED, BUT THAT'S ONE WAY THAT THEY CAN FIND OUT, CHECKING THE WEBSITES FOR THEIR INDIVIDUAL UTILITY OR JUST CALLING THE UTILITY AND ASKING, HAVE YOU TESTED FOR P.F.A.S.

IF YOU HAVE, HAVE YOU FOUND ANYTHING AND WHAT HAVE YOU FOUND?

>> AND SO IF PEOPLE DO SEE IN THOSE REPORTS OR THROUGH PRIVATE WELL TESTING THAT THEY HAVE HIGH LEVELS OF P.F.A.S., WHAT SHOULD THEY DO ABOUT IT?

HOW DO YOU MITIGATE THAT IN YOUR DRINKING WATER?

>> THERE ARE TREATMENT ALTERNATIVES.

I'M NOT HERE TO ADVOCATE ONE WAY OR THE OTHER, BUT THERE ARE TREATMENT ALTERNATIVES THAT CAN REDUCE P.F.A.S.

CONCENTRATIONS IN DRINKING WATER.

THOSE INCLUDE ACTIVATED CARBON, LIKE A CHARCOAL FILTER, IT MIGHT BE IN A PITCHER FILTER OR SOMETHING THAT'S ATTACHED TO YOUR KITCHEN SINK.

THERE'S ALSO IN-LINE EXCHANGE, WHICH IS LESS COMMONLY USED.

THAT'S MORE FOR LARGE USERS LIKE UTILITIES THAT ARE TREATING IT BEFORE IT'S SENT OUT TO CONSUMERS, AND THEN THERE'S REVERSE OSMOSIS, AND THAT'S ANOTHER WAY THAT YOU CAN REMOVE.

SO THOSE ARE THE THREE GENERAL TECHNOLOGIES THAT ARE AVAILABLE.

>> AND SO APART FROM KIND OF THE PICTURES THAT YOU USE BY FILLING IT WITH TAP WATER IN YOUR KITCHEN, PITCHERS, CAN PEOPLE ININSTALL THOSE OTHER KINDS OF FILTERS THAT FILTER THE WATER AT ITS SOURCE?

>> THEY COULD BE ATTACHED UNDER THE KITCHEN SINK, FOR EXAMPLE.

YOU MIGHT HAVE A SEPARATE FAUCET THAT'S DELIVERING THAT FILTERED WATER, AND THAT MIGHT BE, LIKE I SAID, IT MIGHT BE CARBON-BASED SYSTEM OR IT MIGHT BE A REVERSE OSMOSIS SYSTEM, AND SO THOSE SYSTEMS ARE AVAILABLE.

>> CAN YOU DO THOSE SYSTEMS YOURSELF, OR DO YOU HAVE TO HAVE A PLUMBER?

>> DEPENDS ON HOW HANDY YOU ARE.

SOME PEOPLE MIGHT BE ABLE TO DO THAT ON YOUR OWN, BUT IN MOST CASES, IT'S PROBABLY A PLUMBER THAT NEEDS TO COME IN AND DO THAT.

>> WE GOT AN EMAIL FROM A VIEWER WHO TALKED ABOUT THE DISPOSAL OF USED FILTERS FOR P.F.A.S.

AND THAT THEY ARE THEN CONTAMINATED.

RIGHT?

AND HOW SHOULD THOSE BE DISPOSED OF, THOSE FILTERS?

>> THERE REALLY ISN'T AN INFRASTRUCTURE SET UP FOR HANDLING THOSE.

QUITE FRANKLY, THE CONCENTRATIONS OR THE AMOUNT OF P.F.A.S.

THAT MIGHT BE ON THOSE FILTERS IS REALLY SMALL QUANTITIES, AND SO THERE REALLY ISN'T ANY REGULATION IN TERMS OF SPECIAL IS DISPOSAL RECOMMENDATIONS FOR THAT.

TYPICALLY, YOU JUST PUT IT IN THE TRASH AND IT ENDS UP IN THE LANDFILL.

THE PROBLEM WITH P.F.A.S.

IS THAT THEY ARE THESE -- EXCUSE ME, FOREVER CHEMICALS, AND SO THEY DON'T BREAK DOWN.

WE'RE IS NOT DESTROYING THEM WITH OUR TREATMENT PROCESSES.

ALL WE'RE DOING IS CONCENTRATING THEM AND MOVING THEM SOMEWHERE ELSE, AND WE HAVE TO FIND SOME WAY, TECHNOLOGY HAS TO ADVANCE TO BREAK THESE DOWN AND TO BREAK THAT CYCLE.

>> SO P.F.A.S.

IN GROUNDWATER AND DRINKING WATER SEEMS TO GET KIND OF THE BULK OF THE ATTENTION, BUT WE'RE EXPOSED TO THESE CHEMICALS IN A LOT OF OTHER WAYS IN OUR DAILY LIVES.

HOW MUCH SHOULD WE FOCUS ON WATER VERSUS THE OTHER AREAS OF EXPOSURE?

>> YEAH.

I THINK WE SHOULD FOCUS ON ALL OF THEM.

FOOD IN PARTICULAR, IN SOME LOCAL BODIES OF WATER, THERE ARE FISH ADVISORIES, SO THAT'S ONE PIECE.

THERE'S THE DRINKING WATER, BUT THERE'S ALSO CONSUMER GOODS.

WE'RE SURROUNDED BY P.F.A.S.

IT'S IN UP UPHOLSTERY, IT'S IN OUR CLOTHING, IT'S IN OUR CARPETING.

IT'S IN A LOT OF PAPER PACKAGING.

SO IN ORDER TO MITIGATE OR REDUCE OR EXPOSURES, WE NEED TO BE LOOKING FOR P.F.A.S.-FREE ALTERNATIVES, AND SOME OF THOSE DO EXIST AND THERE'S A GROWING LIST OF COMPANIES THAT ARE NOW MAKING P.F.A.S.-FREE ALTERNATIVES, BUT IF YOU SEE THE WORDS "STAIN RESISTANT, STAIN REPELLANT, GREASE REASSISTANT, WATER REPEL MILITANT, ALL OF THESE TYPICALLY MEAN THAT THERE'S P.F.A.S.

IN THEM."

LIKE YOUR ANTI-STICK COOK WARE, THOSE KIND OF THINGS.

IN THE PAST CERTAINLY HAVE HAD P.F.A.S.

AND THERE ARE NOW ALTERNATIVES THAT ARE TRYING TO REMOVE THOSE FROM THE CONSUMER SUPPLY CHAIN.

>> THAT'S GOOD, BECAUSE IT'S
