Contaminants in Tap Water & How Filtration Systems Remove It

A woman, up close and drinking from a glass. The liquid inside the glass is clear but speckled with black bits.

Many are unaware of what might be lurking in their tap water. You could be drinking invisible contaminants ranging from harmful bacteria to heavy metals. Luckily, purifying your water can be as simple as using a filter. Below, we’ll break down the common contaminants in tap water and explain how filtration systems remove them.

Why You’re Finding Contaminants in Tap Water  

Despite the Environmental Protection Agency (EPA) and similar organizations setting federal water standards, drinking water can include a surprising range of contaminants. The EPA regulates 90 substances in drinking water, but many potential contaminants remain unexamined. Additionally, local infrastructure challenges, including aging pipes and outdated water treatment plants, can lead to contamination as water travels to your home.

You don’t escape these problems if you have a well on your property. Private water sources face similar challenges with contamination from agricultural runoff, industrial pollutants, and other environmental hazards.

Identifying Contaminants

Here’s a look at some common contaminants you may find in your water supply:

  • Lead: A toxic substance, especially for children. Corroded, outdated pipes often introduce lead into the water supply, leading to developmental issues.   
  • Nitrates: An inorganic compound that is common in agricultural areas. It seeps into the water supply from fertilizers and runoff. Consuming nitrates in excessive amounts can pose serious health risks.  
  • Bacteria and viruses: E. coli and Giardia are common pathogens that may infiltrate your water supply, especially if your water comes from untreated or poorly maintained wells.  
  • Hard water minerals: Calcium and magnesium make water “hard,” reducing the efficiency of soap and detergent while leaving behind scale in appliances.  

The above list includes some common pollutants, but there are many others that may also pose serious risks, such as pesticides and pharmaceutical residue. For instance, professionals can sometimes detect traces of prescription drugs in some water supplies. Filtration systems help eliminate these substances, making your water safer and more enjoyable to drink.

The Risks of Leaving Water Untreated

Prolonged exposure to these contaminants can have immediate and long-term consequences for your household. For instance:

  • Some scientists believe it possible that elevated lead levels can result in neurological damage in children.
  • High nitrate levels can cause a condition called methemoglobinemia or “blue baby syndrome” in infants.  
  • Pathogen-contaminated water can lead to illnesses affecting the gastrointestinal tract.  

While government agencies and local utilities work to mitigate these contaminants, external protection through a reliable water filtration system builds a stronger line of defense.

How Filtration Systems Solve the Problem  

Filtration systems actively remove harmful substances, ensuring your tap water meets high purity standards before it reaches your faucet. Advanced systems from trusted providers like Delmarva Water Solutions combine multiple layers of technology to address different impurities, delivering hassle-free, high-quality water. Here’s how these systems tackle the key contaminants mentioned earlier.

Comprehensive Sediment and Particle Filtration  

Filtration systems remove sediments, such as sand, dirt, and grit. These particles may damage your plumbing and affect the efficiency of more advanced filtration stages.  

Activated Carbon Filtration for Chemical Impurities  

Activated carbon filters absorb residual chemicals and organic compounds to neutralize the taste and odor of chlorine or chloramines. Carbon is particularly effective at trapping volatile organic compounds (VOCs), leaving your water odor-free and tasting fresh.  

Reverse Osmosis for Precision Penetration  

Reverse osmosis (RO) systems provide unparalleled filtration by forcing water through a semi-permeable membrane. This process removes up to 99% of dissolved contaminants, such as nitrates, lead, and bacteria, effectively safeguarding your water.

UV Sterilization for Bacteria and Viruses  

UV sterilization works in tandem with physical filters to neutralize harmful microorganisms. The UV light destroys pathogens at the DNA level, making them unable to reproduce or cause harm.

Water Softening Technology for Hardness Reduction  

Specialized water softeners eliminate calcium and magnesium ions, preventing scale buildup in your dishwasher or washing machine.

Benefits of Using a Water Filter

Improving your home’s water quality doesn’t just make it taste better. Consider what a properly installed filtration system can do.

Protect Your Health

Filtration eliminates harmful bacteria, heavy metals, and chemicals that might cause significant health issues. Families relying on well water are especially vulnerable to contamination without municipal oversight, making a reverse osmosis filter crucial.

Extend Appliance Lifespan

Hard water and sediment damage appliances over time, reducing their lifespan and forcing costly replacements. Water softeners and whole-house filters are an investment in your health, water supply, and equipment.

Eco-Friendly Hydration

Filtered tap water reduces reliance on single-use plastic bottles. An efficient filtration system allows you to enjoy clean and safe water while lowering your environmental footprint.

Enhanced Taste and Smell

Clean water means better-tasting coffee, tea, and even food preparation, free from the overpowering smells of chlorine or metallic residues.

Physical Improvements

Hard water can leave your skin feeling dry and irritated and your hair looking dull because of its mineral content. Softened, filtered water helps your skin and hair retain moisture, promoting a healthier, more vibrant appearance. Moreover, using purified water for cleaning and bathing reduces the chances of skin breakouts, allergies, or other sensitivities that harsh contaminants could be triggering.
