How drinking water is purified from pesticides, scale, lead, chlorine, viruses and much more.

Pesticides can be removed from drinking water using reverse osmosis or granular activated carbon (GAC) filters. Reverse osmosis works by forcing water through a membrane that allows water molecules to pass but blocks larger ions or molecules, such as those associated with iron, lead or pesticides. In homes, reverse osmosis systems are typically small systems (called point-of-use systems) located near the kitchen sink.

Reverse osmosis systems are cost-effective, but low-end systems may only produce a few liters of treated water each day. Significant recent improvements in membrane elements allow more expensive systems to produce 100 or more gallons per day. The taste of the water can be affected by the removal of minerals.

Granular activated carbon (GAC) filters are relatively inexpensive and simple to use. They remove pesticides and other contaminants that adhere to small particles of material such as coal or charcoal. These filters can take the form of point-of-use systems or pitchers manually filled with water. GAC filters must be replaced or regenerated periodically to maintain their effectiveness. We have a range of different residential and commercial systems that can remove pesticides.

Health effects associated with pesticides in drinking water

There are many different pesticides, each with a different level of toxicity. The health risks associated with pesticides in drinking water are related to how toxic the compound is, how much is in the water, and how much exposure a person gets to the contaminated water. In large doses, which can come from direct exposure to pesticides, they can cause health problems such as cancer, organ damage, reproductive effects, birth defects or nervous system damage. In drinking water, concentrations are usually low, but some pesticides are toxic even at very low levels.

In a study published in 2006 by the US Geological Survey, atrazine (a pesticide that is banned in the European Union but still used in the USA) was detected 90% of the time in streams in agricultural areas and 70% of the time in streams in urban areas, and it was also often found in groundwater [1]. Because groundwater can move very slowly, pesticides can sometimes first appear in drinking water wells decades after the pesticides were applied or spilled, depending on the pesticide's chemical properties and the geological conditions. Because of this, even pesticides that are no longer in use can still contaminate the water supply.

When using pesticides that can contaminate the water supply, the risk of contamination can be minimized by 1) using short-lived pesticides that break down easily, 2) using pesticides that tend to bind to soil and do not move easily, and 3) avoiding disposal of pesticides where they can contaminate water resources, such as near a well or spring or into a storm sewer.

Pesticides are chemicals used to kill or control pests such as insects, weeds, fungi, bacteria, rodents, fish or any other type of organism that poses a problem. Pesticides are often used on agricultural land, gardens and lawns. Pesticides are also used in bodies of water (for example rivers, canals or lakes) to control pests such as mosquitoes, weeds or invasive fish species.

Pesticide contamination of drinking water is very common, especially in agricultural areas. Accidental or illegal spills or dumping of pesticides can lead to drinking water contamination, and even proper application of pesticides can lead to drinking water contamination through leaching into groundwater or runoff into surface water bodies. Pesticide concentrations tend to be highest in streams adjacent to agricultural areas.

Reverse osmosis is an efficient and effective water purification technology that removes most contaminants and dissolved salts from water, making it clean and pure. It is essentially a system for demineralizing or deionizing water using a semipermeable membrane. The process gets rid of potentially harmful and toxic compounds from your drinking water and leaves the water virtually distilled.

A semipermeable membrane is a filter that allows certain particles to pass while preventing others from doing so. If you have a container of water with a high salt content and another with a low salt concentration, separated by a semipermeable membrane, the water with low salt concentration will move toward the container with high salt concentration. This is the natural osmosis process.

With reverse osmosis we try to achieve the opposite by applying pressure. The water is then pushed through the membrane to the other side. The impurities are left as a concentrate or reject stream, and the clean permeate water is obtained.

pH—simplified is a measure of the activity of hydrogen ions (H ⁺ ) present in water with a minus sign.

Why is RO water acidic?

The pH value in RO (reverse osmosis) water can, however, be a cause for concern. Water is assumed to have a pH of 7, which is neutral. But why is it that RO water has a pH between 5 and 6? Isn't that dangerous?

To answer these questions we need to try to understand what causes the pH of water to change. It is important to remember that if a solution has more H ⁺ ions, it is said to be acidic, and if it has more OH ^- ions, it is basic.

A water molecule (H ₂ O) is, as you know, composed of two parts hydrogen and one part oxygen. Self-ionization of water leads to the dissociation of a small percentage of water molecules into hydrogen ions (H ⁺ ) and hydroxide ions (OH ^- ). When the water is stripped of impurities, equal numbers of hydrogen and hydroxide ions cancel each other's influence, and the water remains neutral.

When water is forced through a semipermeable membrane using pressure, many organic and inorganic compounds do not pass through, but gases such as carbon dioxide do get to the other side. CO ₂ combines with the free OH ^- ions in the water to form acidic HCO ₃ , while H ^{+ -} ions do not find substances to interact with, as most of the impurities have been removed through the RO process.

CO ₂ + H ₂ O <--> H ⁺ + HCO ₃^-

As a result, the water has a positive balance of H ⁺ ions, which lowers its pH and makes it acidic. (Remember again, pH is a measure of H ⁺ with a minus. No more chemistry, we promise!).

The greater the amount of CO ₂ in your water, the greater the drop in pH level. However, there is no need to be alarmed, as the acidity of RO water is mild. A few specks of baking soda are enough to neutralize a glass of RO water.

Is acidic water dangerous?

If a pH test of your tap water shows that your household is receiving acidic water, it can be dangerous. Acidic water is corrosive and can interact with lead, copper, zinc and other metals in plumbing and pipes to increase the toxicity in your drinking water. These metals can be harmful to your family's health and well-being. Drinking contaminated water with low pH levels or high acidity, however, is generally safe in the short term.

Your body does a wonderful job of maintaining an almost neutral pH of 7.4 at all times. When you drink a little acidic water, it loses its acidity the moment it comes into contact with saliva in your mouth and the food in your stomach. Your stomach is a strongly acidic place with a pH of 2. Don't think that a little acidic water will have any impact on changing the pH of your stomach or will negatively affect your health in the short term. Admittedly the American population primarily consumes acidic foods and drinks, and the long-term effects of this can be harmful.

Most fruit juices are acidic by nature, and you know how some of them, those without added sugar, are good for your health. There are many other highly acidic beverages you use every day without a second thought. Did you know that soda or carbonated drinks have a pH of around 2.5, and that coffee has a pH of 4? Slightly acidic RO water pales in comparison to most beverages we consume. Average tap water in the USA also has pH levels from 6 to 8.5.

"If you have health problems or are trying to lose weight, stop consuming acidic and sugar-added drinks. It's best to balance the acidity in your diet with a pH-neutral or even slightly alkaline purified water."

If you have health issues or are trying to lose weight, stop consuming acidic and sugar-added beverages. It is best to balance the acidity in your diet with a pH-neutral or even slightly alkaline purified water. In that case, a water purifier that balances pH is a must. Because of the long-term cumulative effect, we recommend using an alkaline remineralizer cartridge on RO systems.

So why not enjoy extremely clean and pure RO water!

The right tool to access RO water

RO water gives you access to almost unsurpassed levels of purity when it comes to your drinking water. It is important to choose the right RO filter to enjoy all the benefits of clean water. If you want to combine the assurance of RO water with convenience, an under-sink reverse osmosis system makes perfect sense. And for offices, an RO-enabled filtered water cooler is a must. The best systems take advantage of the benefits and efficiency of ultrafiltration membranes and can provide nearly 100% pure and contaminant-free water.

The Thunder 4000MP RO and UF System with pump is just the system. It is fully loaded with a comprehensive 17-stage reverse osmosis process with dual ultrafiltration membranes as well as an ultraviolet cartridge to deliver absolutely pure drinking water. Particles as small as one thousandth of a micron are captured by the filter cartridges and the semipermeable membrane. The system removes more than 500 organic and inorganic contaminants from the water.

The system comes with a booster pump for low household water pressure. The compact nature of the system means it is easy to install under the kitchen sink. The system's surprising capacity and efficiency gives you access to up to 100 gallons of clean drinking water each day. A four-gallon pressure storage tank is installed with an ultraviolet cartridge to prevent microbial growth.

Reverse osmosis is a safe, proven method to ensure the water you and your family drink is free from toxic chemicals, heavy metals, pesticides as well as bacteria and viruses. The low pH of RO water is essentially harmless, and if you want to raise the pH of RO water and improve its taste, the best way to do that may be to combine an alkalizing, remineralizing and oxidation cartridge with your RO system (add it to your order with any new RO system, and we will install it).
