Types of Water Contaminants

Bacteria

A Well Water Survey showed that up to 60% of all Wells had unacceptable levels of total Coliforms.  This strongly suggests that disease causing organisms could be present.

A major cause of this contamination is insufficient Well maintenance.

Coliform organisms are a group of bacteria that are frequently found in the environment and are used to measure the safety of your water.  Coliform  present in your water tells you that other disease-causing organisms may also be in your water supply. 

The presence of coliform bacteria in a water sample may mean that surface water has washed contaminants into the Well.

E Coli bacteria live in the intestines of humans and warm blooded animals.

There are many different types of these bacteria.  

If any amount of E. Coli bacteria is found in a water sample, human sewage or animal feces has contaminated the water supply.

When a water sample shows the presence of bacteria, it is considered unsafe to drink until the problem is corrected. 

The bacteria could possibly pose a health risk. The water should not be used for drinking until the problem has been found and corrected. 

An alternate drinking water supply should be used.  Boiling water (rolling boil 5 minutes) that has been refrigerated will also make the water safer to drink.

Nitrates

The presence of nitrates in your Well water is likely the result of farming activities such as fertilizing or seepage from septic systems.

At certain levels  per liter of water, nitrates can hinder an infant’s blood’s ability to carry oxygen and could cause a condition known as “blue baby syndrome.” 

Herbicides & Pesticides 

Herbicides & Pesticides from both agricultural and household use may contaminate Wells if used improperly or exceedingly.

Always read and use the amount stated on the manufacturer’s label.
