Renfrew County and District Health Unit public health inspectors inspect recreational water facilities (pools, spas, splash pads, and wading pools) that are open to the public to make sure they comply with the Ontario Public Pools Regulation 565/90.

Public Health inspectors check these facilities for:
• Water chemistry
• Daily testing records
• System maintenance
• Safety equipment
• Supervision requirements
• Pool operator training
• Signs and markings

To view recent pool and spa inspections, go to the inspection disclosure website.

Please note, beach water testing for the 2023 summer swimming season has now ended. 

One of the jobs for Ontario Health Units is to prevent or reduce illness and injury related to recreational water use. This includes inspecting and testing the water at public beaches during the swimming season.

The water is tested for E. coli bacteria. The presence of E. coli indicates recent sewage contamination. This can be caused by bathers, birds, animals, surface water runoff, sewage spills, private sewage disposal systems and pleasure boats.

Swimming in water with high levels of bacteria can cause skin rashes, eye, ear, nose and throat infections, and intestinal or stomach sickness if the water is swallowed.

If the test results show that there is too much E. coli in the water, a sign is put up. The sign states that the Medical Officer of Health advises people not to swim in the water because of high levels of bacteria. The sign is removed when further tests show that the water is safe for swimming again.

Sometimes a sign is posted at the beach to warn swimmers about other conditions like algae blooms, chemical contamination, or physical dangers.

Beaches owned and operated by municipalities are tested. Other beaches with public access may also be tested if the Medical Officer of Health believes that the beach is popular with swimmers and using the water may result in illness.

Preventing Contamination of Your Well

If you get your drinking water from a private well, have your water tested for bacteria at least three times per year. Testing times should be spread out over the year, for example during or immediately after a spring melt, in mid-summer and in the late fall.

Your well can be contaminated by:

• Openings in the well seal
• Improperly installed well casing
• Well casing not deep enough
• Well casing not sealed
• A source of contamination not related to well construction.
• Improper grading around the well casing.

Take care of your well by ensuring that:

• Sanitary seal or well cap is securely in place and water-tight
• Well cap is at least 40 cm above the ground
• Joints, cracks and connections in the well casing are sealed
• Surface drainage near the well is directed away from the well casing
• Surface water does not pond near the well
• Changes in the quantity and quality of water are investigated immediately

Unused wells should be properly abandoned to prevent pollution of ground water and address any safety hazards. The hiring of a well contractor qualified to seal wells is strongly recommended.

Disinfecting Your Well

If your water test shows that bacteria were in the sample, your well may need to be disinfected (shocked). If you are unsure what the test result means, ask a Public Health Inspector: 613-732-3629 extension 505 or 1-800-267-1097 extension 505.

You can disinfect your well by adding the following amounts of regular chlorinated household bleach (5.25 % chlorine concentration). Do no use lemon-scented or other types of bleach.

• Dug wells one meter (three feet) in width: Add one litre (one quart) of household bleach for every 1.5 metres (five feet) of water depth.
• Drilled wells 15 cm (six inches) in width: Add five ounces (142 ml) of household bleach for every 7.5 metres (25 feet) of water depth.
• Well points 5cm (two inches) in diameter: Add 85 ml (three ounces) of household bleach for every 3 metres(10 feet) of depth.
• If you don’t know how deep the water is in the well, use the well depth to estimate how much bleach to add.

For detailed instructions on how to disinfect your well, see the Disinfection Instruction Sheet.

After disinfecting your well, boil the water for at least one minute before using until you receive good test results. Sometimes you may have to disinfect your well a couple of times in order to kill all the bacteria in the well water.

Emergency Treatment of Contaminated Drinking Water

If you are disinfecting your well it is because the water has been found to be unsafe. Until the disinfection is finished, you can make the water safe by:

• Boiling it for one minute, OR adding eight drops (1.25 ml or ¼ teaspoon) of chlorinated household bleach (not lemon-scented or fabric safe) per 4.5 litres (one gallon) of water. Mix it well and allow to stand for 15 minutes. (This treatment will not kill parasites).
• Chill boiled or treated water until used.

Please contact a Public Health Inspector:  613-732-3629 extension 505 or 1-800-267-1097 extension 505 if you are not sure what type of chlorine solution to use.

Best Management Practices for Water Wells

Green Communities Canada – Well Aware Program

Caring for your Water Well After a Flood

Water wells can become polluted by flooding. Sometimes bad water has a nasty taste, odour, or cloudiness. Other times it tastes, smells and looks the same as clean water.

During a flood, dirty water may get directly into the water table through the well itself, through an old well or some other opening in the ground nearby. In this way it bypasses the natural purifying action of the earth.

Water wells may not be affected by floods. However, homeowners are urged to test all wells in the flooded area for bacteria.

Until tests show the water to be drinkable, all water for drinking should be boiled. Bringing water to a rolling boil for one minute will kill most germs. For more information see Boil water advisory frequently asked questions.

If you think or are told that your well water is unsafe because of chemicals, then boiling will make the problem worse. Instead, use another source of water such as store bought bottled water.

Call the Health Unit at 613-732-3629 extension 505 or 1-800-267-1097 extension 505 for further information about how to disinfect a well.

For more information, visit Best Management Practices for Water Wells, Well Aware or The Walkerton Clean Water Centre.

Renfrew County and District Health Unit provides water testing services for residents who have private drinking water systems.

The best times to sample your private drinking water source are during the spring runoff, during the dry and hot summer, and in the middle of winter. RCDHU offices in Renfrew and Pembroke are the most reliable locations to pick up water sample bottles.

If you get your drinking water from a well, you should have it tested for bacteria at least three times per year. Testing times should be spread out over the year, for example during or just after a spring melt, in mid-summer and in the fall. In addition to regular testing, well water should be tested:

• after any work to pumps or plumbing
• if the well has not been used for several weeks
• if there has been flooding in the area, or
• if there has been a change in water colour or odour

Water testing is free. Sample bottles can be picked up at Health Unit offices. Sample bottles can also be picked up at all municipal offices in Renfrew County and District.

Instructions for taking the sample come with the water sample bottles. Follow the instructions carefully and write all of the information requested on the sample form.

Take the sample as close as possible to the time you will be dropping it off for testing. If you are not dropping off your sample right away, keep it in the fridge or a cooler.

Dropping off your water sample

There are five locations where you can drop off your water sample. (You can also pick up sample bottles.) Note: Around long weekends and statutory holidays, please check with the Health Unit for possible changes to the schedules below.

Interpreting your water test results

Public Health Inspectors are here to help you understand what your water results mean and how to fix any problems with your drinking water. Call the Health Unit at 613-732-3629 extension 505 or 1-800-267-1097 extension 505.

Do not rely on the test results of only one water sample. We recommend you take three samples taken one to three weeks apart to make sure your drinking water is safe to drink.

If you want to check for chemicals in your well water, you need to contact a lab or a water treatment company. Call the Health Unit for more information.

Public Health Ontario – Water Testing

Blue-green algae are microscopic plants that live in water. Under certain conditions they can rapidly increase in numbers to form a large mass called a bloom.

Blue-green algae blooms have occurred on water bodies in Renfrew County and District. The Health Unit advises people to be on the lookout for algae blooms. If you suspect a blue-green algae bloom, assume toxins are present and call the Ministry of the Environment and Climate Change Spills Action Centre at 1-800-268-6060.

The following are precautions to take during a blue-green algae bloom:

• Avoid using the water for drinking, bathing, or showering and do not allow children, pets or livestock to drink or swim in the water.
• Do not boil the water because this may release more toxins into the water.
• Avoid cooking with the water because food may absorb toxins from the water during cooking.
• Be careful when eating fish caught in water where blue‐green algae blooms occur. Do not eat the liver, kidneys, and other organs of fish caught in this water.
• Do not treat the water with a disinfectant like bleach. This may break open algae cells and release toxins into the water.
• Do not rely on water jug filtration systems as they do not protect against the toxins.
• On lakes and rivers where blue‐green algae blooms are confirmed, people who use the surface water for their private drinking water supply should consider an alternate, protected source of water.

For more information see the Government of Ontario’s Blue-Green Algae page, or view the following blue-green algae fact sheets:

Blue-Green Algae Fact Sheet

Blue-Green Algae and Safe Drinking Water

Public Health Inspectors enforce Ontario Regulation 319/08, under the Health Protection and Promotion Act, by conducting on-site risk assessments and inspections of all Small Drinking Water Systems (SDWS) to protect the quality of drinking water and ensure safe water is provided to the public at all times.

What is a Small Drinking Water System?

Any premises or business that offers drinking water to the public from a non-municipal system (i.e. a well, cistern, lake) may be a SDWS.

Some examples include:

• Seasonal mobile home or RV park, campgrounds, or resorts with 6 or more connections
• Restaurants on private water systems
• Hotels, motels and bed and breakfast accommodations
• Recreational and athletic facilities
• Places of worship
• Places where service clubs and fraternal organizations meet
• Any place where the general public has access to a drinking water fountain or shower

If you are an owner/operator of a SDWS, please visit RCDHU’s For Professionals – Small Drinking Water Systems page for more information and resources.

Inspections

Call 613-732-3629 extension 505 with any questions about SDWS inspections or to report a complaint.

To view recent SDWS inspections as well as any adverse water quality incidents (AWQI), please visit Inspection Disclosures.

Inspection reports are also available through the Municipal Freedom of Information and Protection of Privacy Act. Contact Renfrew County and District Health Unit for more information.
