Drinking Water Frequently Asked QuestionsPublicQ1. Who are drinking water officers, and what can they do to protect my water? Drinking Water Officers in the Health Authorities provide surveillance and monitoring of drinking water systems which may affect the public's health. They also administer and enforce the Drinking Water Protection Act, the Drinking Water Protection Regulation and the Health Act and intervene when necessary to minimize health and safety hazards. Q2. Who is responsible for making sure my water is safe? The ultimate responsibility for the provision of safe drinking water supplies lies with your drinking water supplier. They are responsible for complying with the requirements of the Drinking Water Protection Act and Regulation and, in particular, for ensuring that water quality is monitored, and treated if necessary, and for notifying the public when there is a potential or actual problem with drinking water. If you have concerns about your water supply and do not know your water supplier, contact your Drinking Water Health Authority Contact who can provide you with some assistance. Q3. My community water system is under a boil water advisory, and I have a home filter system. Do I still need to boil my water? You may still need to boil your water depending on the particular circumstances of your water supply. Consult with your Drinking Water Health Authority contact or your Drinking Water Officer (if you are aware of who he/she might be) to determine if your existing filtration system will suffice in addressing the potential health hazard. Q4. Not all authorities are consistent in their approach on requirements. Why not? The Drinking Water Protection Act (DWPA) is outcome-based legislation which lends itself to the adoption of different approaches to achieve required outcomes. The Drinking Water Officers’ Guide outlines some principles and provides guidance to the Drinking Water Officers (DWO’s) in the application of the DWPA, however, the decisions of DWOs cannot be prescribed in advance, and must be responsive to the situation before them. Q5. How do Drinking Water Officers decide to require a boil water advisory? Drinking Water Officers require suppliers to notify or advise their customers to boil their drinking water, or take other precautions to safeguard themselves, based on a number of factors. Triggers for public advisories can include:
Q6. My water tastes a little odd, should I be concerned about the safety of my water? A change in water quality such as taste, odour, or cloudiness, can be caused by many things, and could indicate a potential problem. Notify your Water Supplier and your local Drinking Water Health Authority contact about any changes in your water quality. Q7. I have concerns about my drinking water quality, who do I contact to address my concerns? If you have concerns about your drinking water quality you should discuss these concerns with your water supplier and/or with your Drinking Water Health Authority contact. Your water supplier is responsible for providing customers with information on water quality results from testing on your drinking water supply. Q8. I am interested in finding out the results of drinking water quality tests that were performed on my drinking water. Can I obtain these test results and how do I go about obtaining them? Water Suppliers must make this information public in an annual report. Ask your water supplier for this information. If you do not know who supplies your drinking water, contact your local Drinking Water Health Authority contact. Q9. My water is on a Boil Water Advisory, when will I be able to drink the water again without boiling it? Your Drinking Water Officer will advise the water supplier when he/she is satisfied, through appropriate testing or other safeguards, that the water is safe to drink without boiling it. It is the responsibility of the water supplier to inform all users when the advisory is lifted. Q10. My water has been on a boil water advisory for a long while, why doesn’t government do anything about it? Water supply systems may remain on a boil water advisory for an extended period of time as a result of there being a substantial concern with the treatment equipment or distribution infrastructure of the water supply system. Infrastructure changes are usually quite costly and require lengthy planning before they can become operationalized. The Health Authorities use progressive enforcement to ensure compliance with the Drinking Water Protection Act and the requirement for the provision of potable drinking water. Part of this progressive enforcement involves requiring planning information from the water supplier which demonstrates, using critical timeframes, that infrastructure and treatment upgrades are being addressed responsibly. Q11. Why isn’t the water supplier required to have a cross connection control program? A water supplier can be required to have a cross-connection control program if so directed by a Drinking Water Officer, or as part of a system assessment and response plan. Q12. Are the Ministry of Environment source water quality guidelines legally enforceable? Guidelines set by the Ministry of Environment for source water quality are guidelines which are not required by legislation and are therefore not enforceable. The intent behind the water quality guidelines are to outline source water quality objectives for water sources used for a variety of purposes of which drinking water is one such use. Q13. Besides microbiological analyses, how often does a water supplier have to do chemical analyses for their water system? This depends on many factors, such as the source of the water, history of the water system, etc. Testing requirements are determined on a case by case basis by the Drinking Water Officer, in consultation with the drinking water supplier. Depending on the nature of the source water, specific chemicals will be tested.
