Water Quality Testing of Groundwater


Groundwater is the water contained beneath the surface in rocks and soil, and is the water that accumulates underground in aquifers. There is over a thousand times more water in the ground than is in all the world’s rivers and lakes, according to the U.S. Geological Survey.

For millions of people in poor and developing countries, as well as in developed countries, groundwater is the most important or only source of drinking water. Groundwater also is often the most economically feasible source of drinking water.

Although groundwater quality generally is more stable the surface water quality, it is still subject to fecal contamination the poses serious health risks.

Wells and Boreholes


Water quality in wells and boreholes changes and they are potentially vulnerable to intermittent fecal contamination. Here’s how:

  • Fluctuations due to rainfall and rainfall runoff into source waters and groundwater
  • Contaminated surface water and/or groundwater enters improperly constructed well
  • Presence of animals where there are no barriers at well or borehole to protect against animal fecal contamination
  • Poor sanitary protection at the top of the borehole, no sanitary seal or well apron
  • Hand pump base doesn’t have a watertight seal where it attaches to the casing
  • Contamination at the well pump outlet (spout) from contaminated hands
  • Casing doesn’t extend far enough above the ground and surface water enters well, defective well casing and/or liner
  • Contaminated objects fall into well
  • Shallow, open wells are more susceptible to contamination
  • Intermittent septic system intrusion and/or other transient fecal source


Aquagenx Test Kits for Groundwater

E. coli + Total Coliform Kits

E. coli + Total Coliforms test kits provide either Presence/Absence or Most Probable Number (MPN) test results.

E. coli Kits

E. coli-only kits provide Colony Forming Units (CFU) test results.
