Results and discussion

Any other information on results incl. tables

The amount of Triethyl phosphate in well 8 in North Holland was registered in one GC-MS run. Triethyl phosphate was found to be considerably reduced in concentration in the water of Well 8 (70 % reduction).

Applicant's summary and conclusion

Conclusions:
After Triethyl phosphates passage through a soil containing a mixture of fine-grained dune sand, clay and peat 70 % removal of Triethyl phosphate was found in nearby groundwater.
Executive summary:

A study was conducted to measure the effects of soil of the dunes on the removal and modification of organic compounds (including Triethyl phosphate) present in water of the river Rhine during dune-infiltration as a treatment step in drinking water production. This was performed to indicate potentially harmful compounds that occur regularly in water of the river Rhine and in spite of soil passage may occur in drinking water derived from that source. The study was performed in North Holland. The soil of infiltration terrain consists of fine-grained sand mixed with clay and lens-shaped peat-layers.

The amount of Triethylphosphate had reduced by 70 % in the infiltrating water of well 8
