Understanding Arsenic in Tap Water: Risks, Health Effects, and Filtration Solutions

Arsenic is a naturally occurring element found in the Earth's crust. It contaminates drinking water supplies through natural processes and human activities such as agricultural runoff, mining, and industrial operations. Understanding the risks associated with arsenic in tap water and the available filtration solutions is crucial for maintaining public health.

Health Risks Associated with Arsenic Exposure

Skin Conditions

Chronic exposure to arsenic can lead to significant skin issues, including discoloration, lesions, and hyperkeratosis. These conditions are often the initial visible signs of arsenic poisoning and require immediate attention.

Cardiovascular Diseases

Exposure to arsenic has been linked to an increased risk of cardiovascular diseases such as hypertension, ischemic heart disease, and arteriosclerosis. These conditions can severely impact overall health and longevity.


Studies indicate a correlation between arsenic exposure and the onset of diabetes mellitus. Arsenic disrupts insulin production and glucose metabolism, leading to elevated blood sugar levels.

Neurological Effects

Arsenic can cause extensive neurological damage, resulting in cognitive deficits, memory loss, and peripheral neuropathy. These neurological impacts can significantly diminish quality of life and daily functioning.

Pulmonary Diseases

Inhaling arsenic-contaminated water vapor can lead to respiratory issues, including chronic bronchitis and lung fibrosis, posing severe risks to pulmonary health.

Developmental Issues

Exposure to arsenic during pregnancy can lead to adverse developmental effects on the fetus, such as low birth weight, developmental delays, and higher infant mortality rates.
Immune System Disorders
Immune System Disorders

Arsenic weakens the immune system, making individuals more susceptible to infections and exacerbating existing autoimmune conditions.

Cancer Risks

One of the most severe consequences of prolonged arsenic exposure is the increased risk of various cancers, including skin, lung, bladder, and kidney cancers.

Effective Methods for Arsenic Filtration from Tap Water

Reverse Osmosis (RO)

Reverse osmosis is one of the most effective methods for removing arsenic from water. This technique uses a semipermeable membrane to filter out arsenic and other contaminants. RO systems are widely available and can be installed under the sink or as whole-house systems.

Activated Alumina

Activated alumina is highly effective at removing arsenic and fluoride from water. It works by adsorbing arsenic ions onto its surface, significantly reducing their concentration in the treated water.

Ion Exchange

Ion exchange filtration involves replacing arsenic ions in the water with harmless ions, typically chloride or hydroxide. This method is effective for both arsenic (III) and arsenic (V), making it a versatile solution.


Distillation involves boiling water and condensing the steam back into liquid form, leaving contaminants like arsenic behind. Although highly effective, distillation is less practical for treating large volumes of water due to its energy and time requirements.

Adsorptive Media

Certain media, such as modified activated alumina and iron-enhanced activated carbon, can adsorb arsenic from water. These media can be incorporated into various filtration systems to enhance arsenic removal.

Testing Your Water for Arsenic

Before selecting a filtration method, it is crucial to test your water to identify contaminants present and concentrations. Water testing kits are available for home use, or you can send a sample to a certified laboratory for analysis. Understanding the specific contaminants in your water will help you choose the most effective filtration system.

Comprehensive Water Safety

While addressing arsenic contamination is essential, it is also important to consider other contaminants that affect water quality and health. Common water pollutants include lead, mercury, chloramine, and microbial pathogens. Ensure that your water filtration solution addresses all these threats to provide the highest water quality.
Brita® Alkaline Pitcher Filter

Brita® Alkaline Pitcher Filter: Transform Your Tap Water into Healthy Alkaline Water

How does the Brita® alkaline pitcher filter deliver these health benefits?

The Brita alkaline pitcher filter converts ordinary tap water into ionized, H2-rich, alkaline water through these replacement filters.

pH Enhancement and Heavy Metal Reduction

Brita alkaline pitcher filters utilize an ion exchange resin to elevate the pH of tap water to a revitalizing range between 8.5 to 9.5. This process involves increasing the concentration of calcium ions (Ca2+) and magnesium ions (Mg2+), while simultaneously reducing the presence of certain heavy metals such as lead and copper.

Filtration Technology: BPA-Free and Certified

Embedded within the 7-stage filter of the Brita alkaline pitcher filters are components approved by CE and RoHS standards. The filtration process employs activated carbon and KDF (Kinetic Degradation Fluxion), eliminating chlorine and heavy metals from the water. This ensures the removal of impurities while maintaining water purity.

Antioxidant Enhancement for Health Benefits

The Brita® alkaline pitcher filters are designed to impart antioxidant qualities to filtered water. With an advanced active carbon filter, these filters effectively reduce chlorine, dust, grains, and odors, contributing to a cleaner and healthier drinking experience.

Additionally, the inclusion of magnesium, infrared, and tourmaline ceramics further enhances the pH of the water and adds antioxidant properties, promoting overall well-being. Learn more about our alkaline replacement filter for Your Brita Pitcher
