40. CONCLUSIONS • The CSIR-WRI Laboratory undertakes analyses of pesticides, PAHs and Petroleum Hydrocarbons from all Projects on cost recovery basis. Trace Metals can also be analysed in our laboratory. • The CSIR-WRI ECD helps in sourcing funds from various agencies in the analysis process. Donor agencies like OPCW, DANIDA, CIDA, DFID and Other Mining Companies. • ECD Laboratory trains scientist on their specialized water analysis. • The CSIR-WRI is resolved and committed to sustain the inter-laboratory calibration undertaken at both NIVA and IAEA to ensure sustainable quality assurance in our laboratories.

41. RECOMMENDATIONS • Both the Organic & Physico-Chemical Laboratory of CSIR-WRI-ECD would like to be accredited in terms of organic (Pesticides, PAHs, TPH and PCBs) Physico-Chemical analysis – we need funds for that! • National or Regional Laboratory for both Physico-Chemical and Organic Analysis should be put up at CSIR-WRI (We have the space and the land). • Further training will be needed in setting up the calibration curves for pesticides, PAHs and PCBs. Further training on the GC-MS will be needed in order to put the instrument to its maximum use.

42. Training will be needed for all new ECD staff in the laboratory on our QA/QC to ensure continuity and sustainability. • Additional Technical Staff will be needed immediately in the laboratories to help meet the demands. • We would like to recommend a notice board in the reception for the display of our publications.
