Water Quality

In more rural areas, most people rely on private water supplies such as wells.  It is important to test the quality of the water on a regular basis, as many contaminants that can affect your health are colorless, odorless, and tasteless. 

Basic Water quality test packages include tests for coliform bacteria, nitrates, pH, sodium, chloride, fluoride, sulphate, iron, manganese, total dissolved solids, and hardness.  Additional testing should be done based on locally known contaminants and the depth of your well.  For example, pesticides are more likely to contaminate water sources that are closer to the surface in farming communities than in less rural settings.  Generally, a reputable laboratory or testing service can assist you in selecting the best tests to perform in your area. 

Before selecting a laboratory to test your water, ask them about their qualifications, quality control program, and costs to perform the analysis.  Once the lab and test panel have been selected, the lab will send sample bottles and sampling instructions identifying tests that require special sampling and storage procedures.  For example, tests for colifom bacteria require that samples are shipped at a cool temperature, and arrive at the lab within 24 hours of being collected. 

The quality of a water source may change over time, even suddenly.  Changes can go unnoticed as the water may look, smell, and taste the same.  In light of that, your NAHIPA home inspector urges homeowners with well water to have their water quality tested on a regular basis.  This will help ensure that the water source is being properly protected from potential contamination, and that appropriate treatment is selected and operating properly. 

If the results show that a potential health hazard exists, stop using the water immediately.  This source should not be used until properly treated, and additional tests confirm that a health hazard no longer exists.
