Oshawa Water Profile (What Homeowners Should Know)
Oshawa is a prominent city located in Southern Ontario. Most of its drinking water is sourced from Lake Ontario, which is considered surface water. Before the water reaches your home, it undergoes extensive processing at large water treatment plants operated by the Region of Durham.
The water in Oshawa naturally contains minerals such as calcium and magnesium, classifying it as moderately hard. Because of these minerals, residents might observe scale buildup on faucets, kettles, or other household appliances, and soap may not lather as easily as it would with soft water. The Total Dissolved Solids (TDS) level in Oshawa typically ranges between 150 and 200 mg/L, which is well within the safe limits for high-quality drinking water.
The Region of Durham strictly monitors the supply, performing constant testing and treatment to ensure the water meets all Ontario drinking water standards. While seasonal changes or weather shifts can occasionally cause slight variations in taste or odor, the water remains completely safe for consumption.
To further improve taste, reduce mineral hardness, and protect their plumbing systems, some residents opt to install home filtration systems, such as under-sink RO units or whole-house water softeners.

Common water problems in Oshawa
Hard water
Oshawa’s water hardness typically ranges from 7.3–10.2 gpg (about 125–175 mg/L as calcium carbonate). This means the water is moderately hard and can cause scale buildup in plumbing and appliances, as well as spots on dishes and glassware, but it is safe to drink and use.
PFAS
Oshawa’s drinking water, supplied from Lake Ontario, is regularly monitored by the Region of Durham to ensure PFAS levels remain within Ontario regulatory guidelines. PFAS are synthetic “forever chemicals” that can enter water from industrial and household sources and do not break down easily.
Total dissolved solids
TDS measures the total amount of dissolved minerals and salts in water. In Oshawa, TDS levels are typically around 150–200 mg/L, which is lower than many groundwater systems and usually results in a mild, neutral taste. The water is safe to drink, though moderate TDS can still cause light scaling and slightly reduce soap efficiency.
What Oshawa & GTA Homeowners Are Saying About Their Oaks Water System
5-star Google reviews
Read All Reviews On Google (opens in a new tab)I recently came across Oaks wellness water when I was looking for a whole home system for my new home I purchased in Oakville. The team was super educational and helped me find the right system for my home. I ended up going with the pure Haven system that removes all the chlorine contaminants and softens my water along with a point of use reverse osmosis, drinking water system that remineralize the water.
The team was very supportive and helpful. I highly recommend if you’re looking for a water softener installation in Oakville and throughout the GTA.
Thanks to Joeseph and Rob for all their support and help!
Steven Mahabir Just had the VitaSource RO system installed in my place in Mississauga and honestly couldnt be happier. The water tastes so much cleaner, my coffee actually tastes diffrent now (in a good way lol). It’s like getting FIJI water at home!
The install team was really professional and quick. Youssef especially was very good to deal with.
I was a little hesitant at first about the price but the warranty and the 30 day guarantee made it feel like a safe investment. You can really tell the diffrence vs the pitcher filter I was using before…
Highly recommend Oaks if youre in the GTA and looking to upgrade your water setup. Will update after a few months but so far im really impressed with the whole experience.
Hisham Al Hadi We recently had the Oaks Wellness Water whole home water softener system installed, and I couldn’t be happier with the service and quality. The team was professional, punctual, and explained everything clearly from start to finish.
What really stood out is the modern single-tank design - all the other companies tried to sell us bulky two-tank systems, but Oaks’ technology does it all in one. Plus, it comes with a 20-year unlimited warranty, which gave us total peace of mind.
If you’re looking for a reliable whole home water softener in the GTA, Oaks Wellness Water is the best choice for performance, design, and long-term value.
Mohamed I had the pleasure of working with the Oaks water team. They installed a whole home water softener in my home and I was very happy with their service. They also installed a reverse osmosis water, filtration system in my kitchen tap. They were honest and worked very quickly. I highly recommend using them for water softener installation in the GTA
