Testing for Water Well Filtration Systems

Water well filtration systems are made to suit a variety of purposes. The best system for wells differs for every home owner. Most homes will need well water sediment filters, regardless of the system you choose. A good place to start is by testing the water. For a totally unbiased opinion, choose an independent laboratory not connected with a large water company. You should test your system for sediment, the presence of iron, magnesium, calcium and hydrogen sulfide. If you suspect microorganisms or pollution, ask about further testing. You won’t be able to test your well for every known potential contaminant. This could literally mean hundreds of tests.

One of the most common complaints besides the sediment found in wells is the hardness of the water. Hardness is generally caused by the presence of magnesium or calcium. If these minerals are present in your water, you will notice scaling in your sinks and shower. You may also find it difficult to get shampoos and soaps to lather. A water softener is the typical solution for hardness. Most people use a separate drinking water filtration system such as an under sink water filter for drinking and cooking.

In addition to the sediment problem, iron is the other major concern for people with well water. Iron can be present in two forms: soluble and insoluble. Insoluble iron can be seen and causes discoloration in your appliances. Some insoluble iron may be caught in the sediment filter, but most is removed through filtration systems. Softeners, well water filters or a combination of both systems can be used, depending on the levels present of each type in your well.

You won’t need testing to detect the presence of hydrogen sulfide in your well. This gas can be recognized by the smell of rotten eggs in your water. It is caused by decaying animal and plant materials. Most sediment filters and systems that remove iron and magnesium will also remove hydrogen sulfide. When you have your well water tested, be sure to mention the smell. Since this is a gas, it won’t be detected from a small sample. By the time it reaches the lab, the gas will have dissipated.
