SUMMARY OF RESULTS

Bacteriological Quality:

Your water did not contain any coliform including E. coli.

Health Quality:

Your water contained elevated concentrations of Lead. Concentrations for Lead exceeded the recommended limit of 0.005 mg/L (reported concentration was 105 mg/L)

Your CWQI result for health parameters is Marginal. Marginal indicates that caution must be taken to protect human health and sufficient water treatment should be conducted to raise the water quality to acceptable levels, prior to drinking. It is recommended that a water treatment specialist reviews this report card.

Aesthetic and Operational Parameters:

Your water contained elevated concentrations of Sodium, Total Dissolved Solids, Total Hardness (as CaCO3), True Colour,

Your CWQI result for aesthetic and operational parameters is Poor. Poor indicates that the water will have an undesirable taste and/ or smell.In addition, the water may negatively affect the efficiency and effectiveness of the treatment, disinfection, and distribution of the water. It is recommended that a water treatment specialist reviews this report card.


Recommendations:
  1. It is recommended that a water treatment specialist review this report card.
  2. If you have outstanding questions or concerns, you can schedule an appointment to discuss results with a My Water Quality specialist (licensed hydrogeologist) using the link below.

  1. Your raw water exceeds the drinking water objectives for 1 parameters resulting in a general health CWQI rating of 100 (Excellent).NOTE:Your raw drinking water supply is not potable due to the presence of bacteria.
  2. Your treated water exceeds the drinking water objectives for 1 parameters resulting in a general health CWQI rating of 52 (Marginal).
  3. Your treatment system does not appear to be effective. It is recommended that your have your water treatment system inspected.

Health parameters of concern

Parameter Description Health Effects
LeadLead is a naturally occurring element. However, naturally occurring lead is rarely found dissolved in drinking water sources. The main source of lead in drinking water is through corrosion of plumbing materials with lead or brass components, such as in some pipes, solder, faucets, fittings, and older galvanized well liners. Health basis of MAC: Reduced intelligence in children measured as decreases in IQ is the most sensitive and well established health effect of lead exposure. There is no known safe exposure level to lead. Other: Possible effects include behavioral effects in children. Reduced cognition, increased blood pressure, and renal dysfunction in adults are also possible. Classified as probably carcinogenic to humans

Aesthetic/Operational Parameters of Concern

Parameter Description Treatment Options
SodiumSodium is a common element in the natural environment and is often found in food and drinking water. In drinking water, sodium can occur naturally or be the result of road salt application, water treatment chemicals or ion-exchange water-softening units. At concentrations greater than 200 mg/L the water will have a strong salty taste.Distilation, Reverse Osmosis
Total Dissolved SolidsNaturally occurring; sewage, urban and agricultural runoff, industrial wastewater. TDS above a concentration of 500 mg/L can effect taste and result in excessive scaling in water pipes, water heaters, boilers and appliances.Reverse Osmosis
Total Hardness (as CaCO3)The operational guideline for hardness in drinking water is set at between 80 and 100 mg/L as calcium carbonate. Hardness is caused by dissolved calcium and magnesium, and is expressed as the equivalent quantity of calcium carbonate. On heating, hard water has a tendency to form scale deposits and can form excessive scum with regular soaps. However, certain detergents are largely unaffected by hardness. Conversely, soft water may result in accelerated corrosion of water pipes. Hardness levels between 80 and 100 mg/L as calcium carbonate (CaCO3) are considered to provide an acceptable balance between corrosion and incrustation. Water supplies with a hardness greater than 200 mg/L are considered poor but tolerable. Hardness in excess of 500 mg/L in drinking water is unacceptable for most domestic purposes. Water Softener, Distilation
True ColourThe aesthetic objective for colour in drinking water is 5 TCU (True Colour Units). Water can have a faint yellow/brown colour which is often caused by organic materials created by the decay of vegetation. Sometimes colour may be contributed to by iron and manganese compounds produced by processes occurring in natural sediments or in aquifers. The presence of organic materials is the main cause of disinfection by-products when water is treated with chlorine. Water Softener
