Please rate this spring




This is a well know water source in the Hamilton / Ancaster area. This area is covered with many naturally occurring small springs, this artesian well goes down to 120 meters / 394 feet from the surface to achieve better volume. This aquifer originates from the water table near the Georgian Bay area.

    Based on the lab analysis posted in the pictures, I would be concerned about the following:

    1. Arsenic was 0.021ppm which is 21X the 0.001ppm level for drinking water standards
    2. Barium was 0.08ppm which is 40X the 0.002ppm level for drinking water standards
    3. Turbidity of 1.71 NTU is 17X the 0.1 NTU drinking water standards

    • Mo Rosati says:

      A link to the Ontario Drinking Water Standards has been posted in ‘more info’. This is where I got the following numbers, which are all below the Ontario Drinking Water Standards:

      1. Arsenic was 0.021 mg/L …0.025 mg/L = level for drinking water standards
      2. Barium was 0.08 mg/L … 1 mg/L = level for drinking water standards
      3. Turbidity of 1.71 NTU … 5 NTU = level for drinking water standards

    This depends on the source for your standards,
    the ontario drinking water standards ODWS are posted in the picture as well:

    and all of these elements are below the drinking water maximum… so i'm not sure where you are getting your standards from

    Question to Mo Rosati:

    Please email me at I would like to know the answer to this question- Is it safe to use the sulpher spring water in ancaster ontario ( not the drinking tap one but the other stinky one ) for my bath on going, and at what RATIO? Currently, I fill the tub up with just hot water letting it sit half hour to burn off the chlorine, then I light a candle and pour in the high concentration of the sulpher water into the tub of about 12 liters. Please help.

      Hi Venessa ( I just sent this reply to your e-mail but I thought I would post it here for others to see as well )

      Yes, it’s perfectly safe to use the water at 820 Sulphur Springs Road for bathing purposes, it’s the best way to get that highly mineralized water into your body & bypass your taste buds & your intestinal system. I do not actually use ANY ratio of tap water at all, I gather enough of this water to bath in all by its self ( about 60 to 80 liters of it ) then let it sit at room temperature to warm up or if it’s hot out, I’ll let it sit in the sun for about 4 hours & it will heat up to 98 degrees Fahrenheit. When the Sulphur Springs Spa hotel was in business, they would just heat the sulphur water & use it all on it’s own ( without diluting it ) & provide sulphur baths to the hotel visitors.

      The method you’re describing below should still be beneficial to some degree but I imagine the effects would be very subtle because of the ratio of heated tap water to sulphur water. I do realize that it’s a lot of work to gather enough of this sulphur water to fill a bath & getting it warm enough to bath in is even more difficult but I’m always thinking of ways to make it easier. Now if you had a specific part of your body that needed to be treated ( for example a hand, foot, elbow, knee etc . ) than it would be easy to heat up 4 – 10 liters of sulphur water & than just soak that part of your body in the water for as long as you needed. A friend of mine came up with a great idea, she was planning on bringing a kiddie pool directly to the sulphur spring, filling it up with water & just jump in, it would be freezing though!

      Anyway, I hope this info helped – please feel free to contact me anytime.

      Mo Rosati –

    can you drink this water and still be healthy even though it hasa pH of 8.14

    The water test results are posted on site. The results on Sept.13, 2011 as posted:
    Alkalinity: 157 mg/L
    Floride: 0.28 mg/L
    Calcium: 32.1 mg/L
    Conductivity: 489 omhos/cm
    Sulphate: 25.4 mg/L

    If your looking for a specific ingrediant, and the amount contained in the water, post and I will respond..

    I was going to us this source to supply water for my cooler at home but after reading of the elevated arsenic levels, I am hesitant.  World Health Organization recommended max. concentration of As in drinking water is 10ppb (0.010mg/L) so measurements of 21ppb are certainly of concern….

    Just took a TDS reading of the Ancaster spring water and got a reading of 201. Also a new sign was posted at the spring when I went today saying that the most recent test results found slightly elevated levels of sodium in the water and that people with hypertension should consult their physician before drinking.

    There has not been any information posted about this spring since 2012. I would like to post some up to date information about this spring that people might find useful.

    This spring is tested every 6 months by the Hamilton Conservation Authority. The testing began in 1999 and still continues today. The most recent test was done in February of 2016.

    The water has a prominent “egg” smell and taste. I assume it’s due to the sulphate. Whether or not you appreciate the smell/taste, it is worth noting that it dissipates completely within 1 week of storage. I think this would happen even faster if you left the tops off your containers.

    The water is very silky; meaning it has a very low mineral taste. It does not feel like work to swallow. It is very pleasant tasting once the sulphate dissipates.

    When heating this water to make tea, it does not change the flavour of your tea. The other spring I was going to previously had about twice the mineral content of this one and I found that all of my teas tasted off.

    The spring itself is very beautiful. The area is clean and rustic and the people who visit are friendly and talkative.

    It takes me approximately 1 hour 30 minutes (one way) to get to this spring and I have to rest my containers for about a week before using this water. However, I find these two minor inconveniences worth the fact that this is the only spring I am currently aware of that is tested by a conservation authority periodically. This makes me feel comfortable about consuming the water without any risk of getting ill.

    I highly recommend this spring to those wanting to try spring water for the first time in a safe manner or those who, like myself, are regular spring goers and want to find a clean tasting, but tested source.

    Stay away from this well. I used to get my water from the effingham spring until recently when the people who lived in that area blocked me from leaving and said they were getting the city to cap the well, this was 2 months ago.

    I assumed I could use ancaster as a back up, I Was wrong. I have checked the PH level 3 times now, at home and directly at the source, it is sitting at 5.8-6 and the reading from the city of Hamilton is showing fluoride in the water. Someone has clearly tampered with the flow further back underground. My body PH has always been 7-7.25 and now its at 6.5 after drinking this water for 6-8 weeks.

    You have been warned.

    The HCA is voting on closing our spring please join us on June 22nd at 7pm at the Cooetown Community centre to discuss this spring, how it used and its future. Find out more at and please sign our petition

  13. Vanessa says:

    This spring is set for closure due to the government changing the legal limit of arsenic.

    The water has always been within the limits until the change. If you want to support the spring staying open please sign the petition and attend the meetings if you are able. I believe in the right to choose spring water–and for free. Many people have been getting their water here for years. Some people for more than 20 years. The government is forcing us into consumerism and controlling our resources. Is this what you want?

  14. Andrew says:

    I visited about a week ago. The well is now gated with swipe card access. One sign explains why:
    “On January 1, 2018 the maximum legal limit for arsenic in drinking water wells established by the Ontario Ministry of Environment and Climate Change, will be 0.010mg/L.
    The concentration of arsenic in the water at the Ancaster Well has always been below the existing legal limit of 0.025mg/L over the past 5 years, but it will fail to meet the new standard.

    If you want to continue to harvest the water, you can find info about how to obtain a swipe card at:
