Treated water quality depends a lot on the quality of supplied source water, therefore BOTH PARTIES agree to technically arrange the criteria of source water quality and of treated water quality in appendix II that is attached to this CONTRACT. If the treated water quality does not fully conform to the criteria as outlined in APPENDIX II of this CONTRACT, BOTH PARTIES agree to make the necessary adjustments to reach the criteria of treated water quality that has been determined and that this is not a NEGLIGENCE by the FIRST PARlY to the SECOND PARlY.
