Understand a Home’s Water Quality Before Purchasing


Water Test

When considering purchasing a home, the quality of the water supply is a crucial factor that often goes overlooked. Ensuring the water in a potential home is safe and meets health standards is essential for the well-being of its occupants. This guide provides insights into assessing a home's water quality before making a purchase.

Why Water Quality Matters

  • Health and Safety: Contaminated water can pose significant health risks, including gastrointestinal diseases, reproductive problems, and neurological disorders.

  • Appliance Lifespan: Hard water, high in minerals, can damage appliances, reducing their efficiency and lifespan.

  • Overall Comfort and Quality of Life: Clean water contributes to better skin, hair health, and overall comfort in a home.

Assessing Water Quality

  1. Public vs. Private Supply:

  • Public Supply: Request the latest Consumer Confidence Report (CCR) from the local water supplier, detailing the water quality and any contaminants found.

  • Private Wells: Conduct a comprehensive water test for contaminants such as bacteria, nitrates, heavy metals, and other pollutants.

  1. Professional Testing:

  • Consider hiring a professional to conduct a detailed water quality test. This can provide a comprehensive analysis of the water's condition, covering aspects not included in standard tests.

  1. Home Testing Kits:

  • For a quick assessment, home testing kits are available. While not as detailed as professional tests, they can indicate the presence of common contaminants.

  1. Understanding Test Results:

  • Learn to interpret the results by comparing them to the standards set by the Environmental Protection Agency (EPA) or consulting with a professional for analysis.

Mitigation and Treatment Options

  • Filtration Systems: From whole-house filters to point-of-use options, various systems can remove contaminants, improving water quality.

  • Water Softeners: These are essential for areas with hard water, helping to protect appliances and plumbing.

  • Regular Maintenance: For homes with private wells, regular testing and maintenance are crucial to ensure ongoing water quality.


Assessing a home's water quality is a vital step in the home-buying process. It not only ensures the safety and health of the occupants but also contributes to the longevity of the home's appliances and plumbing. By understanding how to evaluate water quality and knowing the options for treatment and mitigation, buyers can make informed decisions, ensuring their future home meets their standards for clean and safe water.
