PB2
Large scale substrate injection pilot-test in Utrecht, Holland.
The pilot-test is designed (Tauw) to test several
combinations of substrates in a discrete alternating groundwater flow system.
Using 3 well arrays, substrate is injected in the middel while
groundwater flow changes every 2- 4 weeks from direction between the outer rows
of wells (30 total). Shown here is
the groundwater flow control unit including the computer console which regulates
the system and records data such as groundwater elevation, flow rates of the 5
pumps and errors occuring in the system. All
data are transferred by modem to the offices of Geo & Hydro, Tauw and the
City Council of Utrecht.
