Explanation of Terms From Quality, Sixth Edition (Health Canada, December 2010) For more information, visit Health Canada at http://www.hc-sc.gc.ca/ewh-semt/water-eau/drink-potab/guide/index-eng.php Maximum Acceptable Concentrations (MACs) Maximum acceptable concentrations (MACs) have been established for certain substances that are known or suspected to cause adverse effects on consumption of drinking water containing the substance at that concentration. The use of drinking water for all usual domestic purposes, including personal hygiene, has been considered in the derivation of the guidelines wherever possible. However, water of higher quality may be required for some special purposes, including renal Drinking water that continually contains a substance at a level greater than its MAC will contribute significantly to consumers' exposure to the substance and may, in some instances, induce deleterious effects on health. However, shortterm excursions above the MAC do not necessarily mean that the water constitutes an undue risk to health. The amount by which, and the period for which, the MAC can be exceeded without posing a health risk must be assessed by taking into account the toxicity of the substance involved. When the MAC for a substance is exceeded, however, the minimum action required is immediate resampling. If the MAC continues to be exceeded, the local authority responsible for drinking water supplies should be consulted concerning appropriate corrective action. Interim Maximum Acceptable Concentration (IMAC) For those substances for which there are insufficient toxicological data to derive a MAC with reasonable certainty, interim values are recommended, taking into account the available health-related data, but employing a larger safety factor to compensate for the additional uncertainties involved. Interim maximum acceptable concentrations (IMACs) are also established for those substances for which estimated lifetime risks of cancer associated with the guideline (the lowest concentration in drinking water that is practicably achievable using available analytical or treatment methods) are greater than those deemed to be essentially negligible. Becuase of their nature, IMACs will be reviewed periodically as new toxicological data and new methods of quantitation and treatment become available. Aesthetic Objective (AO) Aesthetic objectives (AOs) apply to certain substances or characteristics of drinking water that can affect its acceptance by consumers or interfere with practices for supplying good-quality water. For certain parameters, both AOs and healthrelated guidelines (e.g., MACs) have been derived. Where only AOs are specified, these values are below those considered to constitute a health hazard. However, if a concentration in drinking water is well above an AO, there is a possibility of a health hazard. Practical Quantitation Limit (PQL) The practical quantitation limit (PQL) is the concentration of a substance that can be measured in a laboratory within reasonable limits of precision and accuracy. Other mg/l Milligrams of analyte per litre of water Bq/L Becquerel is the SI derived unit of radioactivity µs/cm Specific conductivity units NTU Nephelometric Turbidity Units is a measure of water cloudiness CFU Colony-Forming Units is a measure of viable bacterial and fungal members TCU True Colour Units is a measure of water purity SI International system of units (also known as the Metric System) < Actual values are less than the detection limit indicated Actual values are less than, or equal, to the detection limit indicated 3 of 19 Raw Potable Well Test Results to 2016.xlsx
