<br /> GROUND WATER MONITORING
<br /> The ground water monitoring network, shown in Figure 1, consists of 14 monitoring wells, MWl
<br /> through MW14, and an extraction well, EWI. All wells which contain enough ground water to
<br /> allow proper sample collection protocol, shall be sampled. Ground water monitoring shall D
<br /> consist of the following: D
