8 Guidelines & Objectives L18288 CONTD... PAGE 8 of 8 Sample Parameter Qualifier key listed: Qualifier Description DLDS HTC TKNI Detection Limit Raised: Dilution required due to high Dissolved Solids / Electrical Conductivity. Hardness was calculated from Total Ca and/or Mg concentrations and may be biased high (dissolved Ca/Mg results unavailable). TKN result is likely biased low due to Nitrate interference. Nitrate-N is > 10x TKN. Health Canada MAC Health Related Criteria Limits Nitrate/Nitrite-N* Criteria limit is 10 (1.0 if present as all Nitrite-N). High concentrations may contribute to blue baby syndrome in infants. Lead* A cumulative body poison, uncommon in naturally occurring hard waters. Fluoride* Present in fluoridated water supplies at 0.8 to reduce dental caries. Elevated levels causes fluorosis (mottling of teeth). Total Coliforms* Criteria is 0 CFU/100mL. Adverse health effects. E. Coli* Criteria is 0 CFU/100 ml. Certain E. Coli bacteria can be life threatening. *Health Canada Canadian Drinking Quality Guidelines (MAC limit) Aesthetic Objective Concentration Levels Alkalinity Acid neutralizing capacity. Usually a measure of carbonate and bicarbonates and calculated and reported as calcium carbonate. Balance Quality control parameter ratioing cations to anions Bicarbonate See Alkalinity. Report as the anion HCO3-1 Carbonate See Alkalinity. Reported at the anion CO3-2 Calcium See Hardness. Common major cation of water chemistry. Chloride Common major anion of water chemistry. Conductance Physical test measuring water salinity (dissolved ions or solids) Hardness Classical measure or capacity of water to precipitate soap (chiefly calcium and magnesium ions). Causes scaling tendency in water if carbonates/bicarbonates are present (if >200 ). For drinking water purposes waters with results <200 are considered acceptable, results >200 are considered poor but can be tolerated. Results >500 are unacceptable. Hydroxide See alkalinity Magnesium See hardness. Common major cation of water chemistry. Elevated levels (>5 ) may exert a cathartic or diuretic action. ph Measure of water acidity/alkalinity. Normal range is Potassium Common major cation of water chemistry. Sodium Common major cation of water chemistry. Measure of salinity (saltiness).the aesthetic objective (not related to health) for sodium in drinking water is 200. However, where sodium concentration of the drinking water exceeds 20, it is recommended that any person on a sodium restricted diet consult with his/her physician or Medical Officer of Health concerning the use of that water. Sulphate Common major anion of water chemistry. Elevated levels may exert a cathartic or diuretic action. Total Dissolved Solids A measure of water salinity. Iron Causes staining to laundry and porcelain and astringent taste. Oxidizes to red-brown precipitate on exposure to air. Manganese Elevated levels may cause staining of laundry and porcelain. Heterotrophic Plate Count Criteria is 500 cfu/ml Measure of heterotrophic bacteria present. GLOSSARY OF REPORT TERMS Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation. Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.
