Maintaining your well


Should I have my water tested?

  Water Sample Bottle

The question of whether or not to have your water tested is a serious one that concerns the health of you and your family. Your water should be safe to drink and acceptable for all other household uses.


If you obtain drinking water from your own well, you alone are responsible for assuring that is safe. For this reason, routine testing for bacteria, nitrates, and anything else of concern, even if you do not perceive a change in your water, is highly recommended.



Even if you currently have a safe, pure water supply, annual testing can be valuable because it establishes a record of water quality. This record can be helpful in solving any future problems and in obtaining compensation if someone damages your water supply. You should also have your complete water supply system annually inspected by a certified and/or licensed water supply professional.


When to test your well water? If your drinking water comes from a well, it's important to have your well water tested for bacteria a minimum of once per year.  You should also test your water:

  • If you notice changes in water quality, including taste, odour and appearance; or
  • after major plumbing work or well repairs
  • if regular well users experience unexplained health problems that may be water related (e.g. stomach cramps, diarrhea, cold or flu like symptoms or vomiting)
  • after flooding (if flooding is common in your area you may want to retrofit your well. Contact an licensed well contractor)

 Tests results help homeowners and occupants determine if their water is safe to drink, or if further investigation of their well is needed.   



What could be wrong with my water?

Even though your water may appear to be fine, there are many possible contaminants that that you cannot taste, see or smell.  Read more....  




UV Treatment




What is UV treatment?

Typical UV disinfection systems involve the flow of water through a vessel containing a UV lamp as shown in Figure 1. As the water passes through this vessel, microorganisms are exposed to intense ultraviolet light energy which causes damage to genetic molecules (i.e. nucleic acids: DNA or RNA) needed for reproductive functions. This damage prevents the microorganism from multiplying or replicating in a human or animal host. Because the microorganism cannot multiply, no infection can occur. Disinfection of water is achieved when UV light causes microbial inactivation.

Advantages of Ultraviolet

The advantages of UV disinfection over other disinfection methods include:

  • No use of chemicals (or a reduced amount of chlorine chemical when it is combined with UV disinfection)
  • No known production of chemical by-products
  • Simple to install, operate, and maintain
  • Inline process requiring no contact tanks
  • Inexpensive to operate

 The Dynamics


Groundwater comes from an aquifer. An aquifer can cover many square miles and is composed of spaces filled with water in various layers of material beneath the ground. In one area, there may be sand or gravel deposits. In others, the shale may contain many fractures. Still others have dense rock that may have relatively few fractures. These cracks and voids fill with the water that soaks down through the ground and form a water-bearing stratum called an aquifer.


Once a well fills to its static level, the level at which water in the well is the same as that in the ground around it, no more water will come in. If no water is removed from the well, it will cease producing. If water is withdrawn from the well, more will come in. Most wells spend a majority of their lives in a non-productive state.

Two things limit the amount of water that a well can produce-time and well yield.

The water level in a well will vary depending on the rate and duration of pumping cycles. The well yield increases toward its maximum as the water level inside the well declines. The lower the level inside compared to that outside, the larger the pressure difference and the faster water will move in. The closer the level inside compared to that outside, the slower the well fill rate will be.

Low-yield wells pumped for long periods experience significant variations in water level. Pump performance in low-yield well installations varies with water level changes. Every pump has a finite amount of energy that it can spend to lift water and provide pressure. The more energy it must spend lifting water, the less is available with which to provide pressure. read more ...
