The clogging of recharge wells, main subjects

Artificial infiltration of (prepurified) surface
water into the subsoil (artificial groundwater re-
charge) is an important process in drinking-water
preparation in the Netherlands and elsewhere. The
research by Dutch waterworks and other concerns was
conducted and financed since 1973 under the auspi-
ces of the VEWIN* association and supervised by the
KIWA** Committee on Artificial Recharge. Speciali-
sed areas such as the recharge-wel1 research are
being investigated in greater depth by various wor-
king groups. The participants (see PREFACE) are re-
presented in the working groups and, more often
than not, at the Same time in the Committee.
