Dangers of Poor Water Quality: Contaminants, Health Risks & Water Treatment Solutions 

Reviewed by Paschal’s licensed plumbing professionals based on field experience across Arkansas, Oklahoma, Missouri, and Texas. 

Most of us assume that the water coming out of our faucet is safe. But even clear, clean-tasting water can contain harmful contaminants that affect your health, home, and plumbing. 

This guide breaks down the most common contaminants found in residential water, the potential impact on your health and home, and how to identify when it’s time to take action. Whether you’re noticing strange tastes, spotting buildup, or just curious about what’s in your water — you’re not alone in asking the right questions. 

Common Contaminants Found in Residential Water 

Lead 

Lead typically enters drinking water through corroded pipes, solder, and fixtures. Even small amounts are toxic, especially for children and pregnant women. Long-term exposure can lead to developmental delays, kidney damage, and high blood pressure. 

⚠️ Important: Lead has no taste, color, or odor — only water testing can detect it. 

Chlorine 

Many municipalities use chlorine to disinfect water; chlorine helps eliminate bacteria. However, elevated levels can cause skin and eye irritation, dry out your hair, and result in an unpleasant taste or smell. Over time, it can also contribute to harmful chemical byproducts. 

PFAS (Forever Chemicals) 

PFAS are synthetic compounds used in non-stick cookware, packaging, and industrial applications. These “forever chemicals” don’t break down naturally and are linked to cancer, hormone disruption, and immune system issues. 

Hard Water (Calcium & Magnesium) 

While not hazardous to health, hard water causes scale buildup in pipes and appliances, reducing their efficiency and lifespan. It also leaves spots on dishes, dulls laundry, and can dry out your skin and hair. 

Microbial Contaminants 

Bacteria, viruses, and parasites may enter water supplies—especially in private wells or after flooding. These organisms can cause gastrointestinal illnesses, posing greater risk to those with weakened immune systems. 

Why Poor Water Quality Matters 

You may not see or taste the problem, but over time, poor water quality can cause: 

• Chronic health issues 

• Increased plumbing repairs and maintenance 

• Reduced appliance efficiency 

• Higher utility bills 

• Damage to fixtures, clothing, and dishes 

Simply put, what’s in your water touches almost every aspect of your home and health. 

What Can You Do About It? 

The good news: You’re not powerless. The first step is understanding what’s in your water through a comprehensive water quality test conducted by licensed professionals.

Frequently Asked Questions 

How can I tell if my water is unsafe? 

Look for signs like discoloration, odor, strange taste, or buildup on fixtures. However, many contaminants are invisible—regular testing is the only way to know for sure. 

What are PFAS and why are they dangerous? 

PFAS (per- and polyfluoroalkyl substances) are man-made chemicals linked to serious health issues. They’re persistent, meaning they accumulate in the body and the environment. 

Is bottled water safer than tap? 

While bottled water is regulated, it is not always safer. The best way to ensure safe drinking water is through testing and, if needed, professional filtration systems tailored to your home.
