Groundwater Testing
Most of the fresh water on Earth is groundwater and can contain many components, including microorganisms, gases, inorganic and organic matter. The quality of groundwater not only affects our health, but also impacts society and the economy. Groundwater contamination can adversely affect property values, community image, economic development, and the overall quality of life for all of us. Once groundwater is contaminated, it is often difficult and costly to clean up. Groundwater must be protected from the adverse effects of agricultural and industrial contamination in order to protect the environment, preserve drinking water sources and avoid well contamination.

pH Testing
Determining pH is critical when determining the treatment needs of a groundwater source, as it affects other treatment methods such as softening or disinfection. When water is exposed to the atmosphere, it tends to absorb carbon dioxide, which reacts with the water and in turn forms carbonic acid and H+, which lowers the pH value. Therefore, it is important to measure pH immediately after sample collection to ensure the most accurate reading. pH is usually determined by an indicator or meter.
Conductivity Testing
Conductivity is a measure of a substance's ability to conduct electricity. Conductivity is usually run because it is a quick and inexpensive way to determine the ionic strength of water. Conductivity can be easily measured with a meter. Pure water tends to have a lower conductivity than water containing high levels of salt, minerals, acids or bases.
Iron Testing
Iron is another common problem in groundwater. Iron is divided into three categories: trivalent iron, divalent iron and organically bound iron. Trivalent iron precipitates easily, giving the water a reddish-brown color that eventually settles out. Organic iron combined with organic substances such as tannic acid or lignic acid will also cause the water to appear discolored. Organically bound iron is more difficult to remove. Ferrous iron is usually found in deep wells where there is a lack of oxygen. To determine the exact level, you can perform a benchtop analysis or colorimetric test for iron, or if a certified analysis is required, you can send it to a lab. There are also iron bacteria, which use iron as a food source. A good indication of iron bacteria is the slimy, reddish-brown buildup usually found behind toilet tanks. Iron bacteria can be tested using a bioactive response test (also known as a BART test).
In addition to the above, there are:
- Chemical and biological needs tests
- Bacteriological testing
- Dissolved oxygen, dissolved solids and suspended solids tests
- Sulfate testing and anion testing
- Contamination testing
- Free and total chlorine, chloride and fluoride testing
- SVOC and VOC testing
- Hydrocarbon Analysis
IMPORTANT: Sampling should be performed by personnel familiar with sampling procedures. Analysis should be performed by an accredited laboratory using appropriate analytical methods. Only a trained professional (such as a toxicologist or physician) can tell you if your water is safe to drink.
