Water Analysis


Maria’s water source is municipal water from a neighboring township. She maintains records of the Water Quality reports sent to her on a yearly basis, but decides to send in a sample to a commercial analytical lab, MDS Harris, in Lincoln, Nebraska since her last report is more than eight months old. To complete the sample submission, Maria must fill out an information form and decide what tests she would like performed. She decides on “Irrigation Suitability”, and key results from these analyses are stated below. These results were faxed to her three days after submitting the sample.
