Table below shows the time and drawdown data of an observation well during an aquifer test conducted at a constant discharge of $2\mathrm{.}725\frac{m^3}{m}in.$ The observation well is located at a distance of $30\mathrm{.}48m$ from the pumped well. Determine the distance to and nature of the boundary.
