City Water

Your city water starts out treated, tested, and regulated at the plant โ€” the tricky part is the trip to your tap. ๐Ÿšฐ Along the way it can pick up chlorine or chloramine taste and odor, disinfection byproducts that form in the pipes, and sometimes a little lead from older service lines. The good news: your utility publishes an annual water-quality report you can actually read, and a simple carbon or reverse-osmosis filter handles most of what's left.

Navigating PFAS: Protecting Your Health from "Forever Chemicals"

PFAS is getting into your body through various ways. Let's explore what PFAS is and how we can reduce our exposure.

Understanding TDS: What Total Dissolved Solids Mean for Your Water

Total Dissolved Solids is the most common single number on a water-quality report. Here is what it actually measures, how to read it, and when it should worry you.

Potential Changes to Water Regulations

A look at potential shifts in U.S. water regulations in 2025 โ€” how proposed changes to the Clean Water Act (WOTUS), the Safe Drinking Water Act, and rules for PFAS and lead could affect your tap water, for both city and well users.

Are Microplastics Lurking in Your Drinking Water?

Microplastics are tiny broken-down plastic particles found in drinking water sources โ€” especially bottled water โ€” and across everyday life. Let's explore where they come from and what we can do to reduce our exposure.

Health Implications of Disinfection Byproducts in Drinking Water

Disinfection byproducts (DBPs) are chemicals created during the water treatment process. This article examines the types of DBPs, their potential health effects, and the role of filtration in managing them.

A Balanced Look at Fluoride in Drinking Water

Fluoride, a naturally occurring mineral, has long been debated โ€” particularly its presence in public drinking water. Proponents cite its power to prevent tooth decay, while concerns have been raised about potential health effects. Here's a balanced look at both sides.

A Brief Review of the EPA's UCMR5 Data on Drinking Water Contaminants

The Unregulated Contaminant Monitoring Rule (UCMR) is a program designed to gather data on substances suspected to be present in drinking water but not yet subject to regulation. Here's what its fifth cycle is telling us.

Is the Water You're Drinking Slowly Making You Sterile?

Some contaminants in drinking water are known endocrine-disrupting chemicals. Let's look at which ones are the most harmful and which biological systems they impact.

Well Water If you're on a private well, you're in charge of your own water โ€” about 1 in 8 US households (roughly 23 million homes) are right there with you. The catch is that EPA drinking-water rules don't apply to private wells, so whatever's in your local aquifer flows straight to your tap: things like bacteria, nitrate from nearby farms, arsenic, and hard-water minerals are the usual suspects. The upside? With a yearly test and the right point-of-use filter, you've got full control over what you and your family actually drink. ๐Ÿชฃ Disinfection Byproducts (DBPs) Here's a trade-off most people never hear about: the chlorine that keeps public water safe also reacts with natural organic matter to create disinfection byproducts, or DBPs. The two regulated families โ€” trihalomethanes and haloacetic acids โ€” have been linked at higher long-term levels to certain cancers and reproductive concerns. Disinfection itself is a good thing and isn't going anywhere; the goal at home is simply to trim how much ends up in your glass โ€” something a good activated-carbon filter does really well. ๐Ÿ’ง PFAS - Forever Chemicals You've probably heard them called "forever chemicals" โ€” PFAS are a huge family of man-made compounds that don't break down, so they build up in the environment and in us. They've turned up in drinking water near industrial sites, military bases, and carpet and textile plants, and they're surprisingly widespread. The articles here break down how PFAS are detected, how you're actually exposed, and where the rules are heading โ€” plus the part that matters most at home: getting them out. Reverse osmosis is the most reliable widely-available filter for the job. ๐Ÿงช Endocrine-Disrupting Chemicals (EDCs) Endocrine-disrupting chemicals (EDCs) are a sneaky bunch โ€” even in tiny amounts they can mimic or block the hormones your body runs on. You'll find them in more places than you'd expect: pharmaceuticals, pesticides, and plastics like BPA, phthalates, and atrazine, plus everyday items from food packaging to cosmetics and textiles. Some make their way into drinking water, too. The good news is they're filterable โ€” reverse osmosis paired with activated carbon is your most effective defense at the tap. ๐Ÿงช
