Residential Upflow Filters from Pure Water Products

All units consist of black Vortech tank with riser factory installed, upper basket, Clack in/out head, Clack bypass, and Clack 1″ threaded elbow extensions. Media can be ordered separately.  No gravel is needed. Upflow filters do not work well for many applications. Treatment of iron and sediment, for example. Upflow filters work well for chemical, chlorine/chloramine treatment of city water, or for raising the pH of acidic well water

These filters work well with standard or catalytic granular carbon and with Calcite.  See media on this page.

In most cases it is wise to put a 5-micron sediment filter before and after an upflow filter. See product WH201 on this page for an excellent sediment pre- or post-filter.

A Bad Week for Clean Water and Public Health: How President Trump’s Glyphosate Executive Order and the 2026 Farm Bill Threaten Us All

On Feb. 18, President Trump signed an executive order titled Promoting the National Defense by Ensuring an Adequate Supply of Elemental Phosphorus and Glyphosate-Based Herbicides. Using the Defense Production Act, the order declares glyphosate and elemental phosphorus “critical” to national security and U.S. agriculture.

At first glance, this may sound like a supply chain measure. But in reality, it puts chemical industry profits above public health and clean water.

Why President Trump’s Executive Order on Glyphosate is Dangerous:

Instead of addressing decades of independent research by experts linking glyphosate — a widely used herbicide — to cancer, liver damage, endocrine disruption, and other serious health effects, the executive order pushes for more production.

Glyphosate and other pesticides already pollute our water. Studies have shown these toxic chemicals are widespread in streams and rivers. Despite this, the executive order doubles down, prioritizing the chemical industry’s interests over community safety.

Even more alarming, the order grants legal immunity to chemical producers following federal directives. Communities harmed by contamination could find it even harder to hold chemical companies accountable. And, the U.S. Department of Agriculture (USDA) is now directed to prioritize chemical production even if it increases exposure risks. Waterkeeper

Bed Bugs’ Greatest Fear: Water and Wet Surfaces

Bed bugs have extremely flat bodies and small respiratory openings called spiracles on their belly sides. “If they physically contact a body of water, they’ll get stuck to its surface, blocking their respiratory openings.” Due to its strong adhesive power, water could be very dangerous from a bed bug’s perspective. So, it’s not surprising to learn that they’re extremely averse to moisture.” UC Riverside News

Study Finds Lower Levels of DBPs (by-products of chlorination) in bottled water than in tap water

A new study found that bottled water contains lower levels of disinfection byproducts (DBPs) than chloraminated tap water, averaging less than half the amount found in typical U.S. tap samples. Researchers detected DBPs—including trihalomethanes and haloacetic acids—in all 10 bottled water brands tested, though levels remained relatively low. Spring and groundwater brands tended to have fewer DBPs than purified bottled waters, making them the better choice for minimizing chemical byproducts.

States Are Resisting the Trump Administration’s Efforts to Ease PFAS Regulations Established During the Previous Administration

States are locking in stricter limits on “forever chemicals” in drinking water while the Trump administration’s stated plan to soften those rules remains stalled. EPA said it would delay and partially rescind a landmark drinking water regulation for the synthetic chemicals that had been set by the Biden administration. The plan, announced last spring in a press release, was to formally propose changes last fall and finalize them this spring. Now, the agency that has lost thousands of staff under President Donald Trump is behind schedule. EPA has encouraged states to hold off on adopting the Biden-era limits for the substances that taint the tap water of over 100 million Americans. E&ENews

Water News for January 2026

The Big News in Water Is that The Real News Isn’t Being Reported

The big news in water is that the EPA is no longer prioritizing public heath, as it was created to do, but is quickly being converted to serve the interests of big business.  The Natural Resources Defense Council has identified 66 environmental rollbacks in the first year of the second Trump presidency. Most of the news has been about program cancellation.

After a tumultuous year under the Trump administration, the Environmental Protection Agency (EPA) has adopted a new, almost unrecognizable guise – one that tears up environmental rules and cheerleads for coal, gas-guzzling cars and artificial intelligence.

When Donald Trump took power, it was widely anticipated the EPA would loosen pollution rules from sources such as cars, trucks and power plants, as part of a longstanding back and forth between administrations over how strict such standards should be. 

But in recent weeks, critics say the EPA has gone far further by in effect seeking to jettison its raison d’etre, forged since its foundation in 1970, as an environmental regulator. The EPA is poised to remove its own ability to act on the climate crisis and has, separately, unveiled a new monetary worth assigned to human lives when setting air pollution regulations. The current new value? Zero.

“The EPA was designed to protect public health and the environment and did a remarkably effective job of that,” said William Reilly, who was EPA administrator under a previous Republican president, George HW Bush.

“That record is now at risk and we will see the degradation of air quality in major cities. The administration seems to conceive the purpose of the agency as solely promoting business, which has never been the agency’s mission. That’s revolutionary – it’s not been seen before.”

A vivid illustration of this, Reilly said, was when the EPA asked businesses last year to simply email a request to be exempt from air pollution rules. “The notion you could be excused from a black letter law just by asking for it was startling to me,” he said. “I thought it was a spoof. But it did happen.”

After returning to the White House, Trump vowed to “unleash” oil and gas drilling and the burgeoning AI industry by sweeping away environmental regulations that the president says only serve a “globalist climate agenda” and a “scam” clean energy sector.

The EPA under its current administrator, Lee Zeldin, has zealously followed this lead – initiating 66 environmental rollbacks in the first year, according to a tally compiled by green group Natural Resources Defense Council (NRDC).

This list includes paring back limits on pollutants such as mercury and soot coming from cars and power plants, cancelling grants for renewables and aid for communities blighted by toxins, squashing clean water protections and deleting mentions of the climate crisis from the EPA website.

Scientists warn of alarming growth of huge mats of seaweed in the oceans

Scientists have warned of a potential “regime shift” in the oceans, as the rapid growth of huge mats of seaweed appears to be driven by global heating and excessive enrichment of waters from farming runoff and other pollutants.

Over the past two decades, seaweed blooms have expanded by a staggering 13.4% a year in the tropical Atlantic and western Pacific, with the most dramatic increases occurring after 2008, according to researchers at the University of South Florida.

With Rainfall Far Below Average, Water Scarcity in Northwestern Turkey has Reached a Critical Point

Water scarcity in northwestern Turkey has reached a critical point after the Kadıköy Dam, a key drinking water source for the town of Keşan, effectively ran dry, according to Daily Sabah.  Authorities suspended all water withdrawals after reservoir levels dropped below what is known as “dead storage,” and intensifying droughts linked to rising temperatures are pushing vital water systems to the brink. The Kadıköy Dam supplies drinking water to Keşan. The reservoir, designed to hold 56 million cubic meters of water, has dropped to below 1% capacity. Prolonged drought, extreme summer heat and increased evaporation have driven the decline. According to the Turkish government, rainfall was 26% below the long-term average last year.  Yahoo News. 

“The World Is Entering a Situation of Water Bankruptcy. Water May Soon Be More Valuable than Gold”

What is water bankruptcy?

We are using up water sources faster than they can be replenished, essentially putting us in water debt. In “many basins and aquifers, long-term water use has exceeded renewable inflows and safe depletion limits,” said a report by the United Nations. Other water sources, including rivers, lakes, wetlands, soils and glaciers, have been “damaged beyond realistic prospects of full recovery.”

Like financial bankruptcy, water bankruptcy happens gradually. We “pull a little more groundwater during dry years. We use bigger pumps and deeper wells. We transfer water from one basin to another. We drain wetlands and straighten rivers to make space for farms and cities,” said Kaveh Madani, the director of the UN University’s Institute for Water, Environment and Health and author of the report.  After that, the costs begin to pile up. “Lakes shrink year after year. Wells need to go deeper. Rivers that once flowed year-round turn seasonal. Salty water creeps into aquifers near the coast. The ground itself starts to sink.” The Week.

Forest Service Research Underlines the Importance of Forests for Drinking Water Quality

Across the United States, forests play a major role in protecting our drinking water supply. A U.S. Forest Service analysis found that 89% of public surface drinking water supplies receive at least some surface water from forested lands.

That means forests help filter the drinking water of roughly 150 million Americans. Some western cities, like Portland, Oregon, receive up to 90% of their drinking water from nearby national forests.

In other words, preserving forests helps keep our water clean and reliable. Environment America

Proprietary Water Filters vs. Standard Models

The most “standard” size in point of use drinking water filters uses 2.5″ x 9.75″ replaceable filter cartridges. Over the years the 2.5″ X 9.75″ cartridge (we call it Size 1) has dominated the industry.  Virtually all cartridge makers offer cartridges in this size. Wide use encourages a competitive market, hence lower prices, and a big variety of products to choose from.

Not all filters are made in standard size, however. Some manufacturers create unique filter styles that can have advantages and disadvantages. One advantage is convenience in the form of easy-to-replace filter elements in which the housing itself is discarded. This means easier replacement but greater cost and limited choice in replacements.

A major disadvantage of buying a water filter with proprietary replacement parts is that you are dependent upon the manufacturer to stay in business and continue to supply replacement elements. Most basic drinking water filters are durable products that will last for years, but if the product disappears from the market after a couple of years your only option is to discard the unit and replace it. This happens often. In fact, it is a sales strategy of some makers who regularly discard proprietary filtration units to force replacement with “improved” (slightly different) units.

Below, for comparison, are examples of proprietary and standard filtration units. Both models shown are “simple” undersink filters–filters that treat all the cold water at the sink and dispense the filtered water through the cold-water side of the regular sink faucet. Simple undersink units are easy to install because no extra faucet for drinking water is needed. The principles in this article also apply to regular undersink filters that need their own faucet and to undersink reverse osmosis units.

The unit pictured above is a respected proprietary unit which features regular city water treatment including fluoride removal. Although the manufacturer does not give specifics about the standard 3-filter replacement package, the expectation would be that one is a sediment cartridge, one a carbon block cartridge, and one a fluoride removal cartridge. The unit features easy-to-change disposable cartridges. Go here for more information and purchase details.

Pictured above is a Pure Water Products Standard Simple Undersink Filter. It is offered with many standard 2.5″ x 10″cartridges to select from, including several carbon block filters, several sediment cartridges, carbon block cartridges with lead removal and cyst removal built in, both coconut shell and standard carbons, fluoride and nitrate removal–in other words, a lot of treatment styles to choose from so that the final product can be tailored to the customer’s local water.

Trump Threatens Tariff to Force Water from Drought-stricken Mexico

President Donald Trump demanded that Mexico provide more water to the United States and threatened to raise tariffs by 5% on imports if the country doesn’t open the spigot before the end of the year.

Under a 1944 treaty, Mexico must send 1.75 million acre-feet of water to the United States from the Rio Grande River through a network of interconnected dams and reservoirs every five years. Water is measured in increments needed to cover an acre of land 1 foot deep.

Trump raised the prospect of tariffs in April on social media in response to a shortfall and the State Department announced Mexico committed to providing more water. USA Today.

Theory of Global Warming Formulated in Oklahoma by Gene the Bean

by Gene Franks

Sometime around 1948, when I was almost ten years old and was still known to friends and family as Gene the Bean, I put forth the theory of Global Warming.

My family home in Okemah, OK was only two lots off of the three-service-station intersection of red brick North 4th St. and the very busy black-topped Highway 62–the highway that carried all the traffic between Oklahoma City and Ft. Smith.

When I sat on the south porch of the house in summer, it was hot.

My grandfather lived nine miles north on a seldom-traveled gravel country road that ran the mile that separated Last Chance and Morse (combined population of about 75). On hot summer days when I visited my grandfather and sat on his south-facing porch, it was cool and breezy.

It did not take my nine-year-old brain long to figure out that when you’re in a place where the breeze blows through pastures, thickets  and big shady trees, a place where  there are no cars and trucks in sight, it’s a lot cooler than when you’re in a place where the breeze is blocked by houses and greasy service stations and the sun’s heat is being soaked up by red bricks and black pavement and there is a steady stream of cars and trucks with heat-belching exhaust pipes. That’s when I made my prediction that as more and more cars and trucks come on the scene, and we cut down more and more trees and thickets, and we pave more and more of the land, the warmer the world is going to get.

I formed that theory without computer models or sophisticated analytical equipment, proving that “you don’t need a weatherman to know which way the wind blows.” It was my theory, and I’m sticking with it.

WOTUS Explained

by Gene Franks

When my grandfather built a house on his farm in Oklahoma just before the Great Depression he decided to leave behind the outdoor toilet and washtubs of his family’s previous home and go with modern indoor plumbing. Indoor plumbing was not yet common in farmhouses at the time.

The new house was in the middle of a 160-acre farm and there were no nearby neighbors, so he saw no problem in simply letting the raw sewage and grey water from the home discharge from a pipe into an empty field that sloped down to a small creek. Except on the days when the wind came from the wrong direction, it was easy to forget that raw sewage was collecting just a few feet down the slope. Conveniently, rain washed everything down the hill and eventually into the creek.

My grandfather built his new house about 50 years before the 1972 Clean Water Act when the concept of WOTUS, which stands for “Waters of the United States,” came into being. He followed the prevailing logic that since the land was his, it was no one else’s business where he discharged his sewer water. In 1972 the initial understanding of what the “Waters of the United States” consists of applied mainly to navigable water so my grandfather’s pasture and the tiny creek his sewage eventually washed into were not a great concern.

In 2025, defining WOTUS has become a complicated on-going political dilemma. The scope of WOTUS changes depending on which party is running the EPA. In broad terms, those who value private property ownership over public wellbeing and water quality, most often Republicans, take the view that my grandfather was within his rights to dump his sewage and his leftover farm chemicals and the used crankcase oil from his tractor on the side of his hill and let the rain wash it into “his” little creek. The other side, the radical lefties, take the view that the “Waters of the United States” concept includes the water on a farm in Oklahoma regardless of who owns the land, that all water is part of the Waters of the United States, just as McElligott’s little pool is part of an underground stream which is part of a river which is part of the oceans.

Under President Obama, WOTUS was broadened and more restriction was placed on what could be done on private land and by private businesses. Greater restrictions were placed on private activities that had an effect on the public water supply. The current administration is now working to redefine WOTUS and thus loosen restrictions on private individuals and businesses. Most recently, the new EPA administrator is seeking to remove wetlands, an essential component of nature’s water management system, from control under WOTUS.

Redefining WOTUS according to the way the political winds blow is now expected.  Today’s rural homebuilders have accepted that they have to have an approved septic system for disposal of sewage. That’s progress. The battle today has shifted to do land developers have to be burdened by bothersome WOTUS rules about draining wetlands to build apartments.
