Fig. 2b. Geologic profiles of Well Transects 3 and 6. Nests consist of three individual wells each. Water table depth is generally 0 to 1 m at Nest D and E wells and 1 to 3 m at Nest B and C wells. Transport across confining clay layers within the Black Creek Fm (formation) is probably minor, as evidenced by nitrate-free water collected within the Black Creek, but upward flow of deep ground water may be significant near stream beds. The riparian zone between Transects 3 and 6 is very narrow (ca. 10 m max.).
