Lead in the water supply

Eighteen million Americans live in areas where the water quality is below the standards put forth by law. According to a new report by CNN, hardly anything is being done to correct the issue. Children affected by lead poisoning can have learning and behavioral problems, hyperactivity, slow growth, and hearing loss. Symptoms like head and stomach aches, fatigue, and low iron deficiencies are often mistaken for other illnesses. The only way to properly diagnose lead poisoning is through a blood test. According to The American Academy of Pediatrics, there are no effective medical treatments for lead poisoning and that prevention of exposure is critical. Moreover, the U.S. Council Of Environmental Quality states that the risk of developing cancer is 93% higher in people who drink or are otherwise exposed to chlorinated water. Chlorine is a potential health hazard to both children and adults.

How Lead Affects Adults

There is no safe level of lead for the human body, and unlike other metals, it has no useful biological function. Even low concentrations of lead in the water can cause a significant increase in blood lead levels, and any damage is irreversible.

How Lead Affects Children

Lead is a potent neurotoxin, and it has significant effects on childhood health and development. The Centers for Disease Control and Prevention states that lead exposure can affect nearly every system in a child's body, inhibiting the growth of both physical and mental abilities.

What are PFOS and PFOA?

PFOS and PFOA are human-made compounds that do not occur naturally in the environment. They are fluorinated compounds that repel oil and water. PFOS and PFOA are used in a variety of industrial and consumer products, such as carpet and clothing treatments and firefighting foams. PFOS and PFOA are the two PFASs that are being produced in the largest amounts within the United States. They are extremely persistent in the environment and are resistant to most chemicals and microbial conventional treatment technologies. They are known to bioaccumulate in humans and wildlife.

How do you get exposed to PFOS and PFOA?

PFOS and PFOA are readily absorbed through oral exposure. Potential ways of exposure include ingestion of food and water, use of consumer products or inhalation of particulate matter containing PFAS. PFOA and PFOS have been found in drinking water supplies, typically associated with industrial use, manufacturing locations, or disposal. The EPA has not issued a Maximum Contaminant Level (MCL) for drinking water.

What are the health effects of PFOS and PFOA?

Human Epidemiological studies found links between PFOA exposure and high cholesterol, increased liver enzymes, thyroid disorders, pregnancy-induced hypertension, decreased vaccination response, preeclampsia, and cancer. Human epidemiological research found associations between PFOS exposure and high cholesterol and adverse reproductive and developmental effects.

Soluble/Ionic lead

Invisible, odorless, and tasteless, soluble/ionic lead requires a chemical removal process to be eliminated from the water.

RKIN binders produce a chemical reaction with soluble lead, which creates an ionic bond, kinetically removing lead from the water.

Particulate lead

Granular and similar in size to tiny grains of sand, particulate lead is often a result of lead pipe corrosion and needs to be physically removed from the water.

RKIN's lead filter works at a 0.5-micron filtration level and is specifically engineered to remove lead particles from the water physically.

Eliminates 99.95% of Lead

The RKIN Whole House Lead Filter effectively removes both particulate and soluble lead from your water. When service lines that contain lead corrode, lead can enter into your water supply and contaminate your drinking water. This situation becomes more likely in areas where the water has low mineral content or high acidity, which corrodes fixtures and pipes.

Eliminates PFOA and PFOS

Our RKIN Whole House Lead Filtration system effectively removes chemicals such as, PFOA/PFOS at the entry point of the water supply of your home, business or restaurant. The chemicals are bio-permanent, are resistant to direct oxidation, and do not break down naturally in the environment or the human body. Studies suggest that exposure to the chemicals may lead to cancer.

Removes Giardia and Crypto

The RKIN Whole House Lead Filtration system removes >99.95% of Giardia & Cryptosporidium. These waterborne parasites, common in drinking and recreational waters, can cause diarrheal disease, nausea and stomach cramps. Microbial Cysts are very resistant to chlorine-based disinfectants, so they must be filtered out of the water supply.

Removes Chlorine and Chloramine

Our RKIN Whole House Lead Filtration system removes >99.95% of Chlorine & Chloramine. These disinfectants in the water, added during the municipal water treatment process, can have adverse effects on your health. The most harmful exposure is through inhalation and skin absorption of steam in a shower.

Why Use a Water Conditioner

The mineral build-up, or scale, can occur in plumbing and household appliances when water is hard. Solid deposits of calcium carbonate can form when hard water is heated. This scale can reduce the life of appliances, raise the cost of heating your water and clog pipes. Long-term movement of hard water through pipe results in scale build-up. This can gradually close up the line and lower your water pressure.

Salt-Free Onlisoft Water Softener Combo

OnliSoft is a maintenance-free media designed to prevent scale build-up by transforming hardness molecules into harmless minerals that no longer cling to household and appliance plumbing surfaces. This is accomplished without adding anything to the water, such as salt, acids, or any other chemicals.

The OnliSoft media is non-absorbent and will work for a lifetime. This means that there are no replacements or maintenance required.

The OnliSoft media naturally neutralizes hardness minerals through Seed Assisted Crystallization. This process of capturing, accumulating, and transforming the hardness minerals into inactive microscopic crystal particles occurs without introducing additional substances. These deactivated particles that are suspended in the water pass through and ultimately exit the entire household plumbing system.


Salt-Based Water Softener Combo

Soft water not only delivers greater washing power but it also reduces the amount of soap you need to use by up to 70%. In fact, the Bureau of Statistics found that between 17 and 20.8 cents of every dollar are spent on cleaning products. Soft water can reduce that bill by up to 65%. It can also eliminate extra rinse cycles and hot water. Plus, using less detergent, household cleaners, and chemicals is better for the environment.
