From an article by Randy Christensen and Elaine MacDonald, Nov/Dec 2015, On the Level, Water Canada. Canadian water guidelines are weaker than those in other jurisdictions. Although having an apparent abundance of fresh water, Canada has considerable quality and quantity concerns. These concerns suggest too little is being done to protect the health and well being of Canadians. Our federal and provincial governments determine the level of allowable contamination in drinking water, known as the Guidelines for Canadian Drinking Water Quality
The authors did a study (Waterproof Standards 2014), in which they found Canadian guidelines are weaker than those in the USA,the EU,and Australia…and are at risk of becoming weaker. There is also evidence that Canada has no standards for some substances, where others do. Of great concern is the Federal Provincial Territorial Committee on Drinking Water (CWD) has proposed doubling the allowable level for chromium. Cr-III is an essential nutrient…but Cr-VI is a known human carcinogen and is considered extremely toxic. Cr-VI is the contamination activist Erin Brockovitch exposed, as portrayed by Julie Roberts in the movie. The CWD’s proposal will put us out of step with our international peers and the World Health Organization (WHO).
Herbicide 2-4-D has also been detected frequently in surface water across Canada, and is associated with damage to the nervous system, liver and kidneys…and is considered a possible human carcinogen. Other countries have a standard 1.5 to 3 times stronger than the Canadian standard. Canada has no limit for Styrene, another possible human carcinogen, while the USA, Australia, and the WHO have set limits.
Precedent for better protection of Canada’s drinking water exists. We can do better , but our governments must must find the will to defend public health and protect Canada’s drinking water.
Making pharmaceuticals that degrade before they can contaminate drinking water.
In recent years, researchers have realized that many products, including pharmaceuticals, have ended up where they’re not supposed to be — in our drinking water. But now scientists have developed a way to make drugs that break down into harmless compounds before they contaminate our taps. 
Their report appears in ACS’ journal
Environmental Science & Technology.
The researchers chose to work with a commonly used drug called propranolol — a beta blocker prescribed to treat high blood pressure and to prevent heart problems. It is very stable and has been found in sewage. They made a small molecular change in its structure that didn’t affect its beta blocking activity but allowed it to break down more easily than the 
original form. Further studies are needed, but initial testing showed that the altered drug and its byproducts are likely not toxic. The researchers suggest that a similar approach could be used to re-design other classes of drugs and chemicals to make them more environmentally friendly, too. 
A wide range of active ingredients originating from pesticides, shampoos, lotions, cosmetics, disinfectants and drugs get washed into sewage systems or rivers and streams, ending up in our tap water. 
Scientists don’t have a complete picture yet of what effects these substances have on wildlife and human health, but they are a major concern. Researchers have detected them in low levels in streams and rivers across the United States and in other countries. To address the specific problem of medications in the environment, Klaus Kümmerer and colleagues made tweaks to pharmaceuticals so they degrade after they’ve passed through both the body and sewage treatment systems, which aren’t capable of scrubbing wastewater of all contaminants.
