Response: As noted in the previous EFMC adequary response (8/92), Monitoring Well
3 waz drilled by the surface owner, A.J. Iuppa, who also holds the water right. EFMC
used this well for monitoring purposes through an agreement with Mr. Iuppa.
Ownership of the well waz, however, never transferred to EFMC. Since Mr. Iuppa
retains ownership of the well, transfer is not necessary.
Monitoring Well 4 is a shallow, hand-dug well. In [he previous adequary response (8/92)
EFMC committed to plug and cap this well in accordance with approved plans.
The two wells west of Interstate 25 were azsociated with previous residential
