It also protects your property against long-term damage, such as clogged or corroded pipes, appliance damage, stained fixtures, limescale buildup, etc.

Our free Fairfax County water testing service checks for key contaminants and quality issues:

• pH Level:

  We measure the acidity of your water.

• TDS:

  We measure the concentration of dissolved substances in your water.

• Turbidity:

  We evaluate the clarity of your water. Turbidity can be caused by particles, sediment, or microorganisms suspended in water.

• Chlorine:

  We check for high chlorine levels, which can cause unpleasant taste and odor.

• Copper:

  We test for copper, which can cause blue-green staining in your home and affect the flavor of your water. High levels of copper may also point to corrosive water that is damaging your plumbing.

• Iron:

  We measure the iron content in your water.

• Hard Minerals:

  We measure the concentration of minerals like calcium and magnesium.

• Nitrates:

  We test for nitrates, which are linked to serious health risks, especially for pregnant women and infants.
