“…Van Oorschot etc got the stated the BOD, suspended solids, total nitrogen, total phosphorus, pH, escherichia coli as the hazards according to the discharge standards, and analyzed the risky source and existing preventive measures in the process of the water, grille and initial pond, aeration pool, the second pond, disinfection, and identified the CCPs by using decision tree, and aeration pool was used to illustrate the monitoring scheme of CCPs, CLs and warning limits and deviation-correcting measures, validation procedures etc. The principle of HACCP was applied in the programming of the regional recycled wastewater in Australia , besides HACCP system was applied in the quality control and risky management of the wastewater treatment plant [3]. In 2004, "Using Guide of Recycled Water Safety Plan" was issued by Queensland Environmental Protection Agency, Recycled Water Safety Plan (RWSP) should be put according to the principle of HACCP in the recycled water treatment or use projects, and the RWSP of Springfield recycled water demonstration projects was provided in the guide appendix.…”

Abstract. The Hazard Analysis and Critical Control Point (HACCP) were a systematic approach to identify and prevent hazards by constructing control system. The principles of the Hazard Analysis and Critical Control Point (HACCP) system and its application to urban water supply system were introduced. The critical limits, monitoring system and corrective actions for the CCPs were established, and improves the capability of quality control and risk management in the processes of wastewater to ensure human health and ecology.

“…Artificial recharge of aquifers is increasingly used for short‐ or long‐term underground storage [ Bouwer , 2002]. It is used to stop the decline of groundwater levels, the decrease of spring discharges and to improve the sustainability of aquifers [ Van Oorschot and French , 1996; Raju , 1998; Johnson et al , 1999; Haeffner et al , 2001; Donovan et al , 2002]. Once the technical feasibility of such a solution has been proven, its economic appropriateness has to be considered, and the cost‐benefit evaluation remains the decisive element [ Detay and Bersillon , 1996].…”

Effects of management policies, including artificial recharge, on salinization in a sloping aquifer: The Israeli Coastal Aquifer case

[1] Overexploitation of aquifers may impair groundwater quality and cause salinization, as occurs in the sloping Coastal Aquifer in Israel. The current management policy risks the future of the aquifer as the country's most important water reservoir. The paper examines a variety of policies and studies their impact on the salinization of the aquifer. Two quantitative approaches were applied: (1) a balance approach which was used to calculate the mean salinity of the aquifer water and (2) a 2-D numerical solution of the flow and transport equations in a 10 Â 15 km cell representing a portion of the aquifer. The policy alternatives include desalination of imported freshwater (180-250 ppm Cl À ), desalination of treated wastewater, and injection of the desalinated water. An increased pumping from the aquifer compensates for the injection of these waters. The results show that desalination of imported freshwater or wastewater with no injection would reduce the salinization rate of the aquifer only slightly, and that the effect would be noticeable only after a period corresponding to the retention time of the vadose zone. The alternatives that involve injection of desalinated water would stop the salinization process; the aquifer mean salinity would stabilize around the level that prevailed at the time of implementation of the injection policy. The numerical solution confirmed the conclusions of the balance approach while including the complex effect of the highsalinity boundary condition on the east and the role of thickness variations in a sloping aquifer. This approach addressed the influence of the spatial densities of pumping and of injection and showed that as the density increases, the numerical and balance solutions converge. It is shown that the numerical simulation should be used for future planning of the injection and pumping layout. Finally, calculations based on our results show that the alternatives involving injection of desalinated freshwater provide the lowest cost of improving the aquifer water salinity.
