This slide presentation outlines information on an approach to solving treatment problems that involves these twelve steps: state the problem; review existing data; list assumptions related to the situation; ask detailed questions; develop initial hypothesis; get input from others; develop alternative hypotheses; collect data; review all data; compare data to hypotheses; develop solution; and, document problem and solution. The presentation then applies these steps to an actual case study on reducing NDMA concentrations at the East Bay Municipal Utility District.
