What is the well cap anyway? 

If you own a well, the water well cap is something that you must inspect regularly. Well cap is the lid on top of the Well casing that shows out above ground. Most well caps, usually aluminum or a thermoplastic, that include a vented screen. 

Why is it essential to keep it clean?

The well cap plays a vital role in keeping your family and you safe from contaminants in your water. When installing a water Well pump system, make sure to seal the sanitary cap to prevent water contamination.

Some of these contaminants include:

  • Insects
  • Pollutants in surface water
  • Bacteria, 
  • Pesticides or herbicides from nonpoint source pollution

As water flows across the ground or a road, it picks up debris and chemicals along the way. From streets come gas and oil leaking from cars along with animal litters. Farm areas come chock full of fertilizers, pesticides, or animal waste. This nonpoint source pollutant rolls along with the water until the water slows down, and the heavier contaminant stayed. If filthy water finds its way through your well, your water will potentially get contaminated by these things.

These are the reasons why the WELL CAP is significant.

Correctly put on and sealed cap keeps surface water from getting in. Moreover, it keeps insects out, which again, could sound small, but is more significant than people may think.

Litters from insects can increase the bacteria in well water. Or, as bugs get trapped in the pipes or water, they die and decompose, releasing additional toxic contaminants.

Here are tips to make sure the Well cap is properly sealed?

  1. Make sure you have a licensed water professional install the well water system, including putting the cap on and sealing it. 
  2. Check your water well cap periodically to make sure it is still intact. 
  3. Check to see that well cap hasn’t been tampered with or has been accidentally displaced.

Even though a well cap protects the water from a lot of toxic hazards, it is not the only thing used to make sure that water going into your water is safe.

A variety of sources can also contaminate groundwater, such as

  • Septic tanks leaks
  • Minerals naturally found in bedrock
  • Dangerous chemicals from underground storage tanks
  • Nearby animal operations

Some of these contaminants are not easily recognized and cannot be detected through smell or sight. It is crucial to get your Oregon water tested annually from a certified organization to ensure no unseen dangers are lurking in your water. 

Lastly, do your due diligence and make sure your entire well water system is working correctly.
