We Use a Lot of Water… What Do We Know About Its Quality?

Try to imagine what life would be like without easy access to clean water. Here are some frequently asked questions about our water systems and water quality:

Where does our water come from?

  • The United States has one of the safest and most reliable drinking water systems in the world.
  • The drinking water supplied to our homes comes from either a surface water or groundwater source.
    • Surface water collects in streams, rivers, lakes, and reservoirs as well.
    • Groundwater is water located below the ground where it eventually collects in pores and spaces within rocks and in underground aquifers.

Contaminant affecting water quality:

  • Water can be contaminated by heavy metals (like lead), chemicals (like pesticides), and pathogens (like E. coli) as well. The presence of these can lead to health issues ranging first from gastrointestinal problems and also to long-term effects like kidney damage or cancer.

How is drinking water regulated?

How do I know that the water in my home is safe to drink?

  • The EPA is responsible for making sure that public water supplies within the United States are safe.
  • In 1974, Congress passed the Safe Drinking Water Act, which sought to protect the nation’s public drinking water.
  • In Clarksville, our local water treatment plant makes numerous mandated tests daily.
    • They also provide an Annual Drinking Water Quality Report found here.

In summary, the safety of drinking water depends on its source, potential contaminants, and how it’s treated. It’s crucial to ensure water is regularly tested and then use appropriate filtration or treatment methods if there’s any doubt about its safety.
