Water Quality

The aquifer we draw water from supplies an excellent source of safe, reliable drinking water. The 15 operating wells have varied chemical composition due to the length of time the water has been in the aquifer and the varying minerals the water has been in contact with. Ground water is normally more mineralized than surface water. Mineralization in ground water is very common and has both positive and negative qualities.

Mineralized water that meets the Canadian Drinking Water Guidelines is thought to be healthier and a supplier of needed minerals in the body. Heart organizations suggest that mineralized water is healthier than non-mineralized water. The minerals also add to the taste and in many cases are preferred (although taste is a very personal preference).

Some of the negative aspects of mineralized water are considered “aesthetic” in nature and are not considered to have negative health components. Ground water usually contains higher levels of hardness, iron, calcium and manganese. These four specific components are in Rutland water in varying amounts depending on the wells on-line. During summer months when the irrigation demands are high, the water has higher concentrations of these minerals present because higher mineralized wells are on-line to meet the demand.

How Are You Affected By Mineralized Water

Staining of dishes, bathroom and kitchen surfaces, silverware, house siding, cars etc. These are common complaints about mineralized water. The spotting and staining is increased by the presence of chlorine which is an oxidant that makes the minerals precipitate out of solution. Heat and evaporation can also cause the minerals to come out of the solution. Again, it must be stressed that these minerals are natural and are not injurious to your health in the quantities contained in Rutland water.

Well Depth

Water levels in the wells are measured every two weeks, as shown in the picture. The average well depth is 191 feet (58.2m), with the deepest well in the district being 348 feet (106m).

Water Quality Testing/Monitoring Program

RWD monitors 24 hours/day for Cl2 Free and pH through our SCADA (Supervisory Control and Data Acquisition) system from 2 locations within the district.

Total Coliform / E.coli testing is conducted on a rotation schedule of 2 per week, more added if situation warrants it.

Every Tuesday:

Six samples are tested for Cl2 free, Cl2 total, pH & Turbidity (short test) (plus 2 from the Total Coliform / E.coli list) Depending on the rotation list; we could be collecting up to 8 samples on that day.


Two types of testing are performed on Fridays, (short test) and (full parameter test).
Friday short test -- RWD Standard Sample Site List
Samples taken are tested for Cl2 free, Cl2 total, pH & Turbidity.

Friday full parameter test (every second Friday) RWD Regular Sample Site List
Like every Friday samples are tested for Cl2 free, Cl2 total, pH & Turbidity. With the addition of testing for Hardness as CACO3, Iron, Nitrate, Nitrite, Manganese.

An estimated 392 tests are performed in any given month. This does not include testing that is requested by our customers or during our annual mainline-flushing program.
