H2O Lab

How long will it take for the H2O Water Quality Lab to finalize my laboratory results?

Most samples are analyzed and reported to our customers within 3 to 5 business days, however some test results may take longer.

What should I know about the hardness of my water?

Many industrial and domestic water users are concerned about the hardness of their water. Hard water requires more soap and synthetic detergents for home laundry and washing, and contributes to scaling in boilers and industrial equipment. Hardness is caused by compounds of calcium and magnesium and by a variety of other metals. Water is an excellent solvent and readily dissolves minerals it comes in contact with. As water moves through soil and rock, it dissolves very small amounts of minerals and holds them in solution. Calcium and magnesium dissolved in water are the two most common minerals that make water "hard." 

The hardness of water is referred to by three types of measurements: grains per gallon, milligrams per liter (mg/L) or parts per million (ppm). The table below is provided as a reference.y compounds of calcium and magnesium and by a variety of other metals.

The Environmental Protection Agency (EPA) establishes standards for drinking water which fall into two categories — Primary Standards and Secondary Standards. Primary Standards are based on health considerations and Secondary Standards are based on aesthetics such as taste, odor, color or corrosivity. There is no Primary or Secondary standard for water hardness. In fact, the National Research Council (National Academy of Sciences) states that hard drinking water generally contributes a small amount toward total calcium and magnesium human dietary needs (National Research Council, Drinking Water and Health, Volume 3, National Academy Press, Washington, D.C., 1980) ​

What are the requirements when selling my home regarding my private well?

Contact your loan officer, however, the buyer’s lending institution will most likely require that the well pass a water quality test prior to loan approval. Most lenders require testing for bacteria. Some may require nitrate testing.

When should I have my well tested?

You should have your well tested once each year for total coliform, nitrates and pH levels.  If you suspect other contaminants, you should test for those as well.  You should also have your well tested if:
 

  • There are known problems with well water in your area.
  • You have experienced problems near your well (flooding, land disturbances, and nearby waste disposal sites).
  • You replace or repair any part of your well system.
  • You notice a change in water quality (taste, color, odor).
