Separate values for different soil texture groups are listed. The value for coarse soils is the one that is not bracketed, whereas the value for medium and fine textured soils is given within brackets. Where there are no bracketed values, the value applies to both soil groups.

11 Water Condition, Table 3 Column E; Full Depth Generic Site Condition Standards in a Non-Potable Ground Water Condition, April 2011, Soil-Ground-Water-and-Sediment-Standards-EPA.pdf. IV Maximum Acceptable Concentration, according to: Health Canada, prepared by the Federal-Provincial-Territorial Committee on Drinking Water of the Federal-Provincial-Territorial Committee on Health and the Environment, Guidelines for Canadian Drinking Water Quality, August 2012, Archived: The Federal-Provincial-Territorial Committee on Drinking Water has established a science-based process to systematically review older guidelines and archive those that are no longer required. Guidelines are archived for parameters that are no longer found in Canadian drinking water supplies at levels that could pose a risk to human health, including pesticides that are no longer registered for use in Canada and for mixtures of contaminants that are addressed individually. None Required: Guideline value not necessary. See Guidelines for Canadian Drinking Water Quality for specific reasons for each parameter. V Canadian Council of Ministers of the Environment, Canadian Water Quality Guidelines for the Protection of Aquatic Life, December 2012, Guidelines-for-the-Protection-of-Aquatic-Life-Dec-2012.pdf. NOTE: these are long-term guidelines for the protection of freshwater aquatic life. For available short-term benchmark concentration values, please refer to the full document. VI Canadian Council of Ministers of the Environment, Canadian Water Quality Guidelines for the Protection of Agricultural Water Uses, December 2012, Water-Quality-Guidelines-for-the-Protection-of-Agriculture-Dec-2012.pdf. I = Irrigation water; L = Livestock watering; if none indicated, the value applies to both. Guideline archived or withdrawn: a water quality guideline is not recommended. Environmental exposure is predominantly via sediment, soil, and/or tissue, therefore, the reader is referred to the respective guidelines for these media. I This substance is persistent, bio-accumulative, and toxic; it should be subject to virtual elimination strategies. IX For a complete list of maximum allowable concentrations of Radionuclides, see Guidelines for Canadian Drinking Water Quality, Table 3. X Aesthetic Objective: Aesthetic effects (e.g., taste, odour) are taken into account when these play a role in determining whether consumers will consider the water drinkable. XI NRG = No Recommended Guideline XII Analysis for methyl mercury only applies when mercury (total) standard is exceeded. XIII The methylnaphthalene standards are applicable to both 1-methylnaphthalene and 2- methylnaphthalene, with the provision that if both are detected the sum of the two must not exceed the standard. XIV F1 fraction does not include BTEX; however, the proponent has the choice as to whether or not to subtract BTEX from the analytical result. XV NTU = Nephelometric Turbidity Unit.
