aerated zone. The practical example of analysis using Eq. (7) will be shown in the next
section.
Field Test: In order to confirm the above theory, field tests with eight wells including new
ones were performed in the area shown in Fig. 2. An example of the data obtained is shown
in Table 3, illustrating a difference between C and c' even using Cl~ data. This fact suggests
the existing function of internal storage. The average value of k measured by a NaCl tracer
test was 4.8 x 1CT
1 cm/s.

DATA ANALYSIS
If the steady state is assumed, Eq. (3) is simplified as follows:
C3Q3 = C1Q1 + C2Q2,
C4Q4 = C3Q3 - Co^outL
= C3Q3 - c 0 q *
(qoutL = q*),

where C3Q3 = CJQJ+ cijQj],c 2 Q2
= CJJJQJJJ+ cjyQjy, for the stations illustrated in
Fig. 2.
In the same manner,
Q 3 = Qi + Q 2 ,
Q 4 = Qs - q*.
