Whether purchasing a home or refinancing your mortgage loan will require a disinterested third-party to collect the water sample. This provides a chain of custody that the water has been taken from the property that is being mortgaged.
The EPA levels for acceptable E. coli and Total Coliform is ZERO. Any level of these bacteria can be dangerous to your health and are not acceptable. A microanalysis can be performed by the lab to determine what type and count is present (not included in basic testing). However, disinfecting your well and water supply system is recommended if these bacteria are found regardless of the type and count (Levels).
Changes in your health or if you notice any changes in the waters appearance, taste, or smell. However, there can be contaminants within the water that can go unnoticed for a long time.
Excessive levels of nitrates can cause infantile methemoglobinemia, or “Blue Baby" Syndrome. Infants most at risk are those 6 months old and younger, or infants who are already sick and consume food that is high in nitrates, or who drink water or formula that is mixed with water that is high in nitrates.
Nitrate levels above 10 mg/L (reported as nitrogen) can cause infantile methemoglobinemia. This condition occurs when nitrate is ingested and then converted to nitrite (NO2) by stomach bacteria. The nitrite then reacts with hemoglobin in the blood to form methemoglobin. The buildup of methemoglobin reduces the ability of the blood to carry oxygen. If the level of methemoglobin becomes high enough, the baby’s skin will turn a bluish color and suffocation can occur. Untreated methemoglobinemia can be fatal, but it is reversible with prompt medical attention.
The EPA recommends testing your Well water yearly for at least bacteria. The water quality of a Well is solely the responsibility of the Well owner.
