Table A1.2 (continued) Framework element and components Activity Quality assurance for materials and chemicals applied in the same Materials and chemicals • manner as for water treatment facilities. Materials and chemicals selected to ensure that they do not introduce contaminants into the recycled water system. Element 5: Verification of recycled water quality Components: Parameters monitored in relation to human health include: Recycled water quality monitoring (specifically designed for adenovirus, Cryptosporidium, Escherichia coli • individual systems, taking into pH, heavy metals • account source of water, end uses disinfection byproducts, halogenated and non-halogenated organics, • and receiving environments) benzo(a)pyrene, herbicides and pesticides, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and volatile chlorinated hydrocarbons (VCH). Environmental performance Parameters monitored in relation to the enviroment include: SAR, chloride, chlorine disinfection residuals, nitrate and total nitrogen, available and total phosphorus. Environmental performance Application and discharge site In relation to the environment, monitoring includes the following: monitoring soils (eg SAR, nutrients, pH, conductivity) • groundwater (eg water levels, conductivity, nutrients). • Householder satisfaction is monitored by the operator of the Satisfaction of users of recycled • recycled water distribution system. Complaints are investigated, water particularly when clusters of complaints are received. u Results are provided routinely to EPA and HD. Exceedences of set Short-term evaluation of results • guideline values are reported immediately in accord with an agreed incident protocol. Human health Corrective responses Corrective responses depend on the exceedence. As a minimum, it • involves investigation of plant performance records to confirm normal operation and additional testing to both confirm the exceedence and to identify the source. Environmental performance Responses are specific to the impact, with a focus on identifying the • cause and implementing preventive measures as required. Element 6: Management of incidents and emergencies An incident notification and communication protocol incorporates: Components: • Communication emergency contact lists – Incident and emergency response criteria for defining incidents – protocols notification requirements, including timeframes – media and general communication protocols. – Element 7: Employee awareness and training Components: Employee awareness and Regulatory approval includes the requirement that the plant • involvement is operated by appropriately trained and skilled personnel.
