Health, Pt. Studies examining adult exposures to aluminum have reported mixed results for grip strength (Donald et al., 1989; Golub et al., 1992a, 1992b, 1995, 2000; Oteiza et al., 1993; Drobyshev et al., 2018). Food Chem. (2013). The HBV is based on the latest science, and in particular on rigorous studies that were not available for the calculation of previous HBVs (e.g., the WHO's HBV of 0.9 mg/L and the California EPA's HBV of 0.6 mg/L). In addition, water quality that is non-aggressive towards concrete and cement pipe types and cement mortar linings should be maintained to minimize leaching of aluminum (and calcium, etc.) EHS is doing policy development in terms of monitoring of the distribution system for aluminum and other metals. CCME (2004). (2017) recommends verifying whether adequate recovery of metals has occurred in different sample matrices by comparing digested and undigested samples. Depending on the situation, there are a variety of methods to improve the stability of these parameters, such as installation of treatment, modification of existing treatment processes, enhanced process monitoring and control (at the treatment plant and/or in the distribution system), slow and controlled introduction of new or seasonal sources, and controlled blending of dissimilar sources (Confluence Engineering, 2018). When aluminum-based coagulants are added to the water, chemical reactions occur with particles, as well as with the organic matter naturally present in the source water. Stable water chemistry conditions also minimize the risk of desorption (release) of aluminum and co-occurring health-based contaminants that can be complexed or co-precipitated on or within the legacy aluminum deposits (as well as manganese deposits or other solids). Water Supply Res. LPDWS owners will be required to do an annual sample for specific parameters including aluminum in the upcoming calendar year. Assess., 187(2): 10. Del Toral, M.A., Porter, A. and Schock, M.R. Kriewall, D., Harding, R., Maisch, E. and Schanz, L. (1996). Based on 2015 data obtained from annual reports, 15 of our 31 municipal water treatment facilities using aluminum-based coagulants will exceed an OG of 0.050 mg/L. Neurosci. Click one of the search options below to get started. This becomes a significant issue when the test dose is actually less than the baseline dose in the diet but the combined dose has not been quantified or reported. EPHO sampling of drinking water is meant to validate operational monitoring conducted by the Water System Operator (WSO) and aluminum is not currently in the list of parameters that EPHOs are to sample quarterly. Albizzati, A., More, L., Di Candia, D., Saccani, M. and Lenti, C. (2012). Cetin, I., Nalbantcilar, M.T., Tosun, K. and Nazik, A. Approaches for evaluating the relevance of multiroute exposures in establishing guideline values for drinking water contaminants. (2008). (2017b) study, the reproductive effects of low doses of aluminum chloride were investigated in male rats. J. Inorg. Considering aluminum levels in treated water, use of innovative Best Available Treatment (BAT) systems and adoption of appropriate operational controls by the WTPs in the province, the Water Security Agency believes that the new MAC for aluminum, if eventually adopted as a drinking water standard in the province, may not pose a significant compliance challenge. 96-hour LC 50 The concentration of a toxic material which will bring about the death of 50 The lowest dose at which adverse neurobehavioural effects were observed (i.e., lowest LOAEL (lowest-observed-adverse-effect level)) is 1.5 mg Al/kg bw per day, which was considered equivalent to human dietary aluminum exposure levels (Martinez et al., 2017a). Both pipe specimens were filled with water collected from a water treatment plant (aluminum concentration not reported). (2015). There is increasing recognition that distribution systems represent a complex and dynamic environment, where numerous interactions and reactions capable of impacting aluminum concentrations at consumer taps can occur.

American Public Health Association, American Water Works Association and Water Environment Federation, Washington, DC. The water samples were categorized by the supply source (ground, surface, or a combination of both), the type of water (raw, finished, or untreated distribution samples), and the type of coagulation used in the treatment process (aluminum sulfate, ferric chloride, other coagulants such as cationic polymers, or no coagulant). Environ. JECFA has since revised their PTWI to 2 mg/kg body weight per day (JECFA, 2012) based on the key study, Poirier et al. Under acidic conditions, overdosing can also increase the aluminum residual (Van Benschoten and Edzwald, 1990a). 94-101. Pernitsky, D.J. The NOAEL of 30 mg Al/kg bw per day identified by the authors is based on a dose-related decline in neuromuscular parameters (i.e., foot splay, hind- and fore-limb grip strength) as well as clinical observations, clinical biochemical changes and effects on renal pathology. These no-observed-adverse-effect levels (NOAELs) were based on decreased body weight gain and a slight but significant delay of the vaginal opening at the highest dose level in both studies. (2010) reported 90th percentile aluminum concentrations in pipe section solids that were comparable in groundwater and surface water systems, whereas maximum concentrations were 5.5 and 1.8 times higher in groundwater systems than in surface water.

(2011) study, the effects of aluminum citrate in rats were investigated in accordance with good laboratory practice (GLP) specifications and with a design based on OECD Test Guideline 426: Developmental Neurotoxicity. Available at: https://www.epa.gov/dwstandardsregulations/secondary-drinking-water-standards-guidance-nuisance-chemicals. No scientifically founded explanation could be offered for this finding. In its assessment of aluminum in drinking water, the WHO (2010) did calculate a health-based value of 0.9 mg/L (rounded) but has highlighted the importance of not exceeding the practicable levels of 0.1-0.2 mg/L to ensure optimization of the coagulation process, in order to prevent microbial contamination and minimize deposition of aluminum floc in the distribution system. Seasonal variations in other parameters (e.g., phosphate, silicate) can also impact chemical equilibrium processes. Additional guidance regarding the leaching of aluminum from cement-based materials and linings is available in U.S. EPA (2002). Potential modifying factors that could affect the bioavailability and consequent toxicity of aluminum in humans include the chemical form of aluminum, the presence of other chemical constituents from the diet and the types of complexes that aluminum forms with these dietary ligands. Based on available data, <1% of facilities will exceed the proposed MAC and approximately 10% will exceed the OG.

Compliance monitoring is determined and other protocols to validate the water safety plan are implemented (e.g., record keeping, consumer satisfaction). The vertical axis shows the aluminum concentration on a log scale in moles ranging from -8 to 0 and the horizontal axis shows pH ranging from 4 to 10. In addition, gestational and/or lactational exposure to aluminum can result in developmental effects that include decreased pup weight (often in the presence of maternal effects), delayed maturation, impaired neurobehaviour and changes to brain biochemistry. Canadian Total Diet Study. (2014). American Public Health Association, American Water Works Association and Water Environment Federation, Washington, DC. Aluminum concentrations in the source water ranged from 0.006 - 0.501 mg/L with an average of 0.101 mg/L. Note: Concentrations were calculated assuming the product is used at its maximum use level. British Columbia Ministry of Health (2017). Fenugreek seeds reduce aluminum toxicity associated with renal failure in rats. Mech. In: Proceedings of the Technology Transfer Conference, University of Calgary, Alberta, Canada. The contribution of air to the total exposure is generally negligible. The proposed operational guidance (OG) of 0.05 mg/L is recommended to be applied to locational running annual averages of monthly values for filtered water in treatment plants using aluminum-based coagulants and to all distribution systems based on a locational running annual average of quarterly values. Public health goal for aluminum in drinking water. Distribution systems as reservoirs and reactors for inorganic contaminants. In the study by Poirier et al. The SMCL is not based on levels that will affect humans or animals. Addendum to Vol. American Water Works Association, Denver, Colorado. The results indicate that aluminum is more likely to exist in surface waters than in groundwaters and that there is a 40-50 percent chance that alum coagulation increases the aluminum concentration of finished water above its original concentration in the raw water. Aluminium in drinking water: An overview P T Srinivasan 1, T Viraraghavan* and K S Subramanian2 1 Faculty of Engineering, University of Regina, Regina, Canada S4S OA2 2 Environmental Health Directorate, Health Canada, Ottawa, Ontario, Canada K1A OL2 Abstract Aluminium (Al) is one of the trace inorganic metals present in drinking water. Res. Li, G., Ding, Y., Xu, H., Jin, J. and Shi, B. Aluminum is known to foul reverse osmosis membranes (Allenby, 2004); cation exchange resins must be modified and used at an extremely low pH (Vanloot et al., 2007); lime softening may increase aluminum concentrations (Reijnen et al., 1991; Alabdula'aly, 1998; Kettunen and Keskitalo, 2000; AWWA, 2011a); and chemical oxidants, such as chlorine, are ineffective because the oxidation state of aluminum does not change (Edzwald, 2018). Monitoring of dissolved aluminum concentrations is also recommended for process control. Toxicol., 86: 154-162. Res., 20(4): 329-333. 105-140.

(2011) study is supported by the JECFA (2012) study, which used the same key study and point of departure for its calculation of the provisional tolerable weekly intake of aluminum in the diet. New Brunswick Department of Environment and Local Government (2018). Analyses for aluminum should be carried out as directed by the responsible drinking water authority in the affected jurisdiction. and Cheikh, H.B. Using the same study design, the authors also investigated the neurobehavioural effects associated with the same doses (Martinez et al., 2017a). Brandhuber, P., Craig, S., Friedman, M., Hill, A., Booth, S. and Hanson, A. Canadian Council of Ministers of the Environment, Winnipeg, Manitoba. Haught, R. and Fabris, M. (2002). and Edzwald, J.K. (1990a). However, exposure to both low aluminum doses, as well as the known neurotoxic dose, resulted in recognition memory impairment in the object recognition memory test. (1993a). These observations highlight a complication in pH-dependent strategies for controlling contaminant releases: while some contaminants are released in response to a pH decrease (e.g., lead, manganese), others are released in response to a pH increase (e.g., arsenic, copper, chromium) (Kim et al., 2011).

Acute toxicity studies of aluminium compounds: Antidotal efficacy of several chelating agents. The precipitation of aluminum in the distribution system can also result in operational issues: At high concentrations (5-6 mg/L) aluminum may cause an unpleasant taste, and at very high concentrations (100-500 mg/L) the water may feel "sticky" (Hrudey and Hrudey, 2014).

Aluminum accumulation and neurotoxicity in Swiss-Webster mice after long-term dietary exposure to aluminum and citrate. These analyzers can be used to obtain a rapid or continuous (online units only) indication of changes to aluminum concentrations, which are critical for process monitoring within a water treatment plant (Haught and Fabris, 2002). If the coagulant dose is insufficient to overcome this demand, aluminum remains in dissolved form, resulting in elevated aluminum residuals and suboptimal particle removal (Jekel and Heinzmann, 1989; Edzwald and Van Benschoten, 1990; Van Benschoten and Edzwald, 1990a; Srinivasan et al., 1999; Edzwald and Kaminski, 2009).

All water utilities should implement a risk management approach, such as the source-to-tap or water safety plan approach, to ensure water safety (CCME, 2004; WHO, 2011, 2012). It is noted that, for the timeframe studied (2012-2017), none of the available private system results were above the health based guideline of 2.9 mg/L. Ensuring safe drinking water: Learning from frontline experience with contamination. Water Supply Res. (2004), whereas aluminum ranked third out of 12 elements (manganese was fifth) in Friedman et al. Wang, N., She, Y., Zhu, Y., Zhao, H., Shao, B., Sun, H., Hu, C. and Li, Y. Res., 179(1): 91-101. 313-388. Doc. A review of the data in Table 8 indicates that a facility adding both calcium hydroxide and sodium silicate could add up to 51 μg/L of aluminum to the drinking water. Delineation between dissolved and particulate fractions in a sample is dependent on the filter type and pore size; therefore, water utilities that may have smaller particles or colloids present in the water should consider whether the standard filter size (0.4-0.45 µm pore-diameter membrane) will be suitable. Water utilities should thus aim to decrease total aluminum to <0.05 mg/L in filtered water (prior to fluoride or phosphorous addition) and further strive to achieve a target of <0.03 mg/L when temperatures are <10 °C (see Table 10).
