TI  - Groundwater contamination from well points -- an experience from the Norwegian 
      groundwater monitoring network.
PG  - 437-40
AB  - Until 2005 the observation wells of the Norwegian Groundwater Monitoring Network 
      in Quaternary aquifers were equipped with metal well points with brass lining. A 
      laboratory leaching test using a new well point demonstrated that the well point 
      material (galvanized iron pipe), the brass lining and the solder used to fix the 
      lining could cause substantial contamination of the collected well water with a 
      long list of chemical elements (Sn, Zn, Pb, Sb, Cd, Fe, Cu, Mn and Al), depending 
      on well capacity, contact time water/well point and pH. Because groundwater 
      chemistry is receiving increased attention in groundwater monitoring all wells 
      were equipped with high density polyethylene (HDPE) points during the years 
      2004-2005. The HDPE points did not return any values above detection in a similar 
      leaching test, with some minor values of Zn being the only exception.
