Water softeners are among the products used by some Canadian businesses to reduce water consumption, and a CBC News investigation has found some water purifiers are using the same devices to kill bacteria and toxins in the environment.

Water purifiers use a water supply that’s often polluted with harmful chemicals and other contaminants, but the water in the system is not treated.

Some of the devices are made of a plastic, glass, ceramic or steel, and they contain bacteria and other harmful substances that could make the water less safe to drink.CBC News found some manufacturers are using these same devices on products made by other companies, such as the Canadian Pest Control Association (CPCA).CBC News spoke to more than 100 companies about the products they use.

Products used in water purification include water softeners, water purifier units and disinfectant.CPA says the technology has been around for decades, but it’s been around long enough that it’s no longer regulated.

In some cases, CPCA has been told to stop using the technology because of safety concerns, but CPCA says it’s not stopping the use.

“The products that we’ve seen on the market are not tested, they’re not approved for use,” CPCA spokesperson Andrew McLeod said.

“If we were to say that these products are safe for human consumption, we would be breaking the law.”CPCA says there’s been a lot of concern about the devices for a long time.

In 2014, the company published a statement that said, “The technology used in the use of water softening systems and water purifying devices is not tested to ensure that the equipment complies with health and safety standards.”

“As a result, there is no guarantee that the products are properly tested, or that they are safe.”

The company said, however, that CPCA is not responsible for any products sold by the companies they are dealing with.CBC contacted several companies that have products made with the same technology.

CPCA’s McLeod told CBC News that they have not been told by CPCA to stop making these products.

The CPCA also told CBC that many of the products in question are sold by other manufacturers, and the company did not respond to a request for comment.CBC also contacted the U.S. Environmental Protection Agency and the Canadian Food Inspection Agency.

Neither agency responded to CBC’s requests for comment, or would say whether the products would be tested.

In Canada, the Environmental Protection Act states that any product that uses the same process for the purification of water as one used in an environment does not require approval from the Canadian Environmental Protection Authority.

CPAC also said that it has a strict policy that products made from these materials are to be used only in environments that are safe to consume and that CPAC is not going to sell any product made from those materials.CBC’s investigation uncovered several other products made using these devices.

The devices can remove some contaminants from the water, but some of them contain toxic chemicals.CBC is also investigating the use and safety of the water softner unit in some of the cases that we’re investigating.

In those cases, we’ve spoken with people who say they have seen their water softners get contaminated.

The CBC News series on the water purging devices will be aired Sunday on CBC Radio’s Power & Politics, at 7:30 p.m.

ET and 10 p.am.
