#448 Everything Water Filtration with Gerry Bulfin of Clean Water Store

April 8, 2026·1 hr 3 min·5 clips

Gerry Bulfin reveals how adding chlorine to water with organic material creates regulated, cancer-causing byproducts.

1. Less Stressed Life episode 448 covers residential water filtration with Gerry Bulfin, founder of Clean Water Store and a master water specialist with nearly 40 years of experience. 2. Host Krista Bigler, a functional medicine practitioner, introduces Gerry as someone she has been recommending without his knowing it; Gerry founded Clean Water Store in 1986 specifically to help homeowners diagnose well and city water problems. 3. The episode's organizing framework is Gerry's two-bucket taxonomy: aesthetic water problems (staining, scale, odors, excessive chlorine) versus invisible health problems (arsenic, nitrates, PFAS, bacteria, heavy metals). 4. Gerry explains that city water may leave the treatment plant clean but picks up lead from pre-1960s pipe solder and joints, rust from corroding galvanized distribution pipes, and bacterial biofilm in low-chlorine-residual sections of aging infrastructure. 5. He recommends inspecting the toilet flush tank as a free first diagnostic: blue stains indicate copper pipe corrosion from acidic water, black deposits indicate manganese, and a clean tank with minor sand is a reassuring baseline. 6. For chlorine removal, coconut-shell activated carbon in a whole-house tank is Gerry's standard recommendation — his own system has run for seven years without media replacement — but households with chloramine instead of chlorine need catalytic carbon, which is a different and more expensive product. 7. Water hardness is caused by dissolved calcium and magnesium (not iron), and can damage appliances such as water heaters and washing machines; a repair technician once told host Krista that her washer looked like 'there's cement in it' from hard water buildup. 8. Standard ion-exchange water softeners remove hardness by substituting sodium for calcium and magnesium, adding roughly 150 milligrams of sodium per liter to drinking water — a minor amount but relevant for sodium-restricted diets. 9. Salt-free water conditioners are widely marketed as softener alternatives but do not actually reduce spots or remove hardness minerals; they only prevent scale buildup inside pipes and appliances, making them 'oversold' in Gerry's view. 10. Iron and manganese are the most common well water contaminants in much of the country and produce orange and black staining respectively; they must be filtered with manganese dioxide media before reaching a water softener or the softening resin will foul. 11. Iron bacteria — identifiable as orange slime or filamentous growths inside storage tanks — thrive in aerated iron-rich environments and require upstream chlorine or hydrogen peroxide injection before the iron filter to control. 12. Reverse osmosis under the sink is the most comprehensive treatment for lead, PFAS, heavy metals, and fluoride, but the membrane fouls quickly with hard water or iron unless whole-house pre-treatment is installed in the correct sequence first. 13. Fluoride cannot be removed by activated carbon and requires reverse osmosis; the episode notes that PFAS (forever chemicals) can be treated whole-house but is often more practical and affordable to treat at the point of use. 14. Chlorine disinfection byproducts — formed when sodium hypochlorite reacts with organic material in water — are classified as carcinogens and are heavily regulated at the municipal level; this is Gerry's primary argument for hydrogen peroxide injection over chlorine for well water odor treatment. 15. Hydrogen peroxide oxidizes back to water and oxygen without leaving a sodium residual or chlorine byproduct, making it Gerry's preferred choice despite higher material cost. 16. Krista adds clinical context throughout: excess calcium in hair tissue mineral analysis can suppress thyroid function and cause recurrent gut issues; iron accumulates in the body because humans have no efficient excretion pathway for it, stressing detoxification systems. 17. Gerry notes that approximately half of Clean Water Store's business is iron filtration, shipped as DIY kits with YouTube installation guides and phone support; roughly one-third of customers hire a plumber or handyman for installation. 18. Sulfur bacteria produce hydrogen sulfide (rotten egg smell) by feeding on iron or sulfur in low-chlorine-residual water inside pipe biofilms; the smell is often worse after a vacation when bacteria have had time to multiply undisturbed. 19. Scale-forming water that deposits calcium on pipes protects against lead leaching from older solder joints; corrosive, low-mineral water is actually more dangerous for lead exposure than hard water. 20. Best suited to homeowners with well water, those in older homes on city water with distribution infrastructure concerns, and anyone pursuing a low-toxin household environment; less relevant for city apartment dwellers on newer infrastructure.

As heard by us

A practical look at water filtration, from chlorine byproducts to iron filters.

Krista Bigler and Jerry Bolfin keep the discussion grounded as it moves from chlorine byproducts and municipal versus well water to iron, rust, storage tanks, and the filters that can change the result at home.
