The sobering test results indicating our well water contains high levels of lead and nitrates, as well as E. coli and coliform bacteria, raised more questions than answers.
While lead seemed the most alarming concern, nitrates were another puzzle. Generally nitrates are found in areas where high levels of chemical fertilizers are used in agriculture. They also can be present as a by-product of bacteria.
But the presence of bacteria itself was also a puzzle. Over the years we have tested for bacteria several times. All of the previous bacteria tests were negative.
