Over 43 million people in the United States use private well water as their water source. A 2004 study by the United States Geological Service (USGS) illustrates both the major aquifers of the United States from which some of these people draw their water. The study found that over 23% of wells contained at least one contaminant in excess of public health standards.
The safety of your well water cannot be taken for granted and testing well water is an excellent way to learn what’s in it. Although well water may look, smell and taste fine, it may contain contaminants that are harmful to your health.
There are two times to treat your well: the extremes of dry and wet weather. Since your well is recharged by rain testing during drought and extreme wet weather will show you the range of variability within your well.
It is possible to treat almost any well water problem with the appropriate well water purification system. However it seems like a common misconception to well owners that they can just go out and buy a well water treatment system that will solve any issue. This is simply not true. In order to treat your well correctly you must first identify the contaminants present. Then you may choose the correct well water filter or treatment to remove the contaminants present in your water. The following is a list of the physical characteristics, metals, and common well water contaminants that I test for and treat.
COLIFORM BACTERIA
Coliform Bacteria are groups of bacteria that indicate the possible presence of infectious disease organisms. It is recommended that water with coliform bacteria not be consumed until the problem is resolved. Coliform bacteria may get into the water supply through surface water run-off, especially after heavy rainfall. Fecal coliform, when accompanied by high nitrate and sulfate levels, may indicate a septic system or other fecal pollution source. Coliform bacteria present at a public water supply user’s faucet may be a result of water and sewage pipes being cross connected causing plumbing backflow. In the microbiological section of your report, columns two and three will list a “P” indicating that any presence of coliform bacteria would exceed the MCL and our detection level is a presence. An “A” for absence in column four indicates that no coliform bacteria was detected. A positive result will be noted as “P” for presence. If you have a positive result for total coliform, the sample is automatically tested for the presence or absence of E. coli. The result will be noted as “EP” or “EA” after the “P” in column four. E. coli (a subset of fecal coliform) is a type of coliform bacteria that is indicative of human and animal feces contamination. E. coli presence “EP” indicates that E. coli bacteria is present. E. coli absence “EA” indicates that the coliform bacteria present is a type other than E. coli.
