InnServices prepares annual reports of its performance, operations, and maintenance. These reports are submitted to the InnServices Board of Directors and publicly posted in accordance with the Safe Drinking Water Act, 2002.
Water Hardness is primarily caused by the presence of calcium and magnesium in the water and is reported as CaCO3 mg/L. Water that is hard requires more soap to create a lather, and leads to scaling of appliances and water pipes. Hardness is an aesthetic issue and is not considered a public health concern.
InnServices has tested its four drinking water systems for hardness, here are the latest results:
|Drinking Water System||Hardness as CaCo3 mg/L||Grains per Gallon||Hardness Level|
|Innisfil Lake Simcoe|
(Lakeshore & Cookstown Areas)
|Innisfil Heights||189||11.05||Very Hard|
Sodium in Drinking Water
Sodium 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. The human body needs sodium in order to maintain blood pressure, control fluid levels and for normal nerve and muscle function.
Public drinking water systems under the Safe Drinking Water Act are required to sample for sodium on a regular basis. If the result is over Maximum Allowable Concentration (MAC), it is reported to both the Ministry of Environment, Conservation & Parks (MECP) as well as the Simcoe Muskoka District Health Unit (SMDHU).
Innisfil’s water systems were recently tested for sodium in November of 2021. Here are the results:
|System||1st Sample - Sodium (mg/L)||2nd Sample - Sodium (mg/L)|
|Innisfil Lake Simcoe||30.8||33.4|
|Churchill Wells #1 & #2||22.3||21.8|
|Churchill Well #3||53.3||60.1|
*Maximum Allowable Concentration = 20 mg/L
*Aesthetic Objective/Operational Guideline = 200 mg/L
Sodium in drinking water is not a health concern for most people but may be for someone with specific health issues that require them to be on a sodium-restricted diet. For more information on sodium in drinking water, visit the Simcoe Muskoka District Health Unit's website.
