There are two main types of well testing:
1. For the well's production, abrasives and fill, such as sand and rust.
2. For contaminates and pollution
Why should I test my well water?
Testing your private well water quality,on a regular basis, is an important part of maintaining a safe and reliable source. The test results allow you to properly address the specific problems your water supply. This will help ensure that the water source is being properly protected from potential contamination so that the appropriate treatment is selected and operating properly. It is important to test the suitability of your water quality for its intended use whether it be livestock watering or drinking water. This will assist you in making informed decisions about your water and how you use it.
Basic water potability
Well testing should include tests for coliform bacteria, nitrates, pH, sodium, chloride, fluoride, sulphate, iron, manganese, total dissolved solids, and hardness.
Coliform Bacteria - Indicate the presence of microorganisms in the water that are potentially harmful to human health.
Nitrate - Is a common contaminant found mainly in groundwater. High nitrate concentrations can be particularly dangerous for babies under six months, since nitrate interferes with the ability of blood to carry oxygen.
Ions- Ions such as sodium, chloride, sulphate, iron, and manganese can impart objectionable taste or odor to water.
Sulfate - Excessive amounts of sulfate can have a laxative effect or cause gastrointestinal irritation.
Fluoride - Fluoride is an essential micro-nutrient, but excessive amounts can cause dental problems.
Total Dissolved Solids - Represent the amount of inorganic substances (i.e. sodium, chloride, sulphate) that are dissolved in the water. High total dissolved solids (TDS) can reduce the palatability of water.
Additional Testing - Other tests may be appropriate if a particular contaminant is suspected in the water. For instance, groundwater sources are sometimes tested for arsenic, selenium, and uranium. Both surface and groundwater sources may also be tested for pesticide contamination.
