In the data set, you will also see the letter T, M, or B after the well number, indicating that the measurements were taken at the Top, Middle, or Bottom of the aquifer in the well. Thus, Mw-7B and Mw-7M are from the same well, but from the bottom and from the middLe. Also, other mea surements indicate that water tends to flow toward well mw-9 in this area Problme one Build a mathematical model to determine whether any new pol lution has begun during this time period in the area represented by the data set, I ify the new pollutants and the lo- cation anx time of their source Problme two Before the collection of any data, the question arises whether the intended type of data and model can yeild the desired assessment of the location and amount of pollutants.
