Texas poised to pour billions into water infrastructure

Texas poised to pour billions into water infrastructure

Climate change has brought higher temperatures in Texas that has accelerated reservoir evaporation and created arid conditions. That has reduced water volumes flowing into rivers and streams. State data indicates reservoir storage was only about 67 per cent of capacity last October from a year earlier. The 30 million people living in Texas cannot survive without water. The state’s rapid economic and population growth has put strain on existing water infrastructure. Even before taking that growth into account, time has taken its toll on water infrastructure, particularly in rural areas. About 132 billion gallons of water were lost in 2021 through breaks, leakage and other causes, according to data submitted by public water suppliers to the Texas Water Development Board (TWDB). Old leaky pipes not only waste water but can increase health risks due to contaminants like arsenic.

Health Canada downplayed scientific concerns about risks of toxic pesticide that causes birth defects

Health Canada downplayed scientific concerns about risks of toxic pesticide that causes birth defects

Canada's pesticide regulator repeatedly ignored red flags raised by its own scientists about the health risks posed by the pesticide chlorpyrifos, stalling a review of the pesticide for close to 20 years, documents obtained by the environmental group Ecojustice reveal. All the while, health concerns raised here at home and worldwide about the pesticide were never publicly shared. Commonly used on crops like wheat, in greenhouses and to kill mosquitoes, chlorpyrifos harms the nervous system and can cause brain defects in children. People are typically exposed by consuming contaminated food residue or water. Canadian farmers used on average 360,000 kilograms of the pesticide each year between 2008 and 2016, and a 2017 federal Canadian health survey found traces of chlorpyrifos on 99 per cent of foods sampled.

Northwestern Health Unit warns of blue-green algae in Kenora area

Northwestern Health Unit warns of blue-green algae in Kenora area

The Northwestern Health Unit (NWHU) is warning of blue-green algae blooms in the Kenora area. Blooms have been reported in the northern sections of Lake of the Woods, as well as in the Winnipeg River and Muriel Lake, the NWHU said. The Muriel Lake bloom is being tested, but the NWHU said water samples will not be taken from Lake of the Woods or the Winnipeg River at this time.

Blue-green algae confirmed in Shelter Bay on Lower Shebandowan Lake

Blue-green algae confirmed in Shelter Bay on Lower Shebandowan Lake

The Thunder Bay District Health Unit is warning people to avoid the water at Shelter Bay on Lower Shebandowan Lake after tests confirmed the presence of blue-green algae. The health unit said some blue-green algae blooms produce toxins that pose health risks to people and animals, and the water at Shelter Bay should be avoided while the bloom is present, and for about two weeks after it dissipates.

It's not just the smoke — as climate change prompts more wildfires, hidden health risks emerge

It's not just the smoke — as climate change prompts more wildfires, hidden health risks emerge

And though the risks from smoke are among the biggest worries, there are also less-obvious health concerns such as the impact on mental health and clean water to consider. The particles that waft into the air affect more than just physical health. Those particles also land on trees, plants, buildings and end up in water. Ash, sediment and minerals not only flow into streams and rivers, but also downstream into lakes and reservoirs, potentially affecting drinking water and contributing to algal blooms. The good news is that in Canada the water purification systems are able to filter them out for the most part. But the added strain on the system means that it may cost more to handle the higher level of contaminants.

Indigenous TikToker uses platform to call out mass contamination of Yellowknife's toxic Giant Mine

Indigenous TikToker uses platform to call out mass contamination of Yellowknife's toxic Giant Mine

An Indigenous filmmaker is using TikTok to raise awareness about the toxic mess left behind at Giant Mine in Yellowknife, N.W.T., and the health risks it poses to the surrounding community. Morgan Tsetta, a Yellowknives Dene First Nation photographer and filmmaker working in Vancouver, has been posting videos about the mine in an effort to pressure the federal government for an apology and compensation.

Tottenham’s water shows little improvement after installation of aeration system

Tottenham’s water shows little improvement after installation of aeration system

The aeration system that had the potential to significantly reduce the level of trihalomethanes (THMs) in Tottenham’s drinking water is struggling to make much of a difference. The Town of New Tecumseth hired engineering consultant R.V. Anderson Associates Limited to conduct a year-long review of the effectiveness of the $800,000 aeration system activated at the Mill Street reservoir in October 2019. The report concluded that the annual running average level of THMs declined 10 per cent compared to prior sample data from 2019. The report also found the variability of THM levels has been reduced by six to 10 per cent within the distribution system.

Lack of funding for piped water on First Nations in Sask. means some on reserves can’t drink from their taps

Lack of funding for piped water on First Nations in Sask. means some on reserves can’t drink from their taps

Rebecca Zagozewski, executive director with the Saskatchewan First Nations Water Association, says cisterns can pose health risks to those who rely on them. She says the structures can have cracked lids, which allows all sorts of debris to get into them — including rats, mice, drowned puppies and garbage — and they’re often not cleaned properly. On top of that, she says the Saskatchewan First Nations Water Association is concerned that there is no certification program for water truck drivers. The group wants to create such a program where drivers would have to be trained in how to keep the water safe and be held accountable if things go wrong. “Because right now there’s no accountability,” she says.

City of Calgary cancels annual mail-outs, testing for lead in water due to COVID-19

City of Calgary cancels annual mail-outs, testing for lead in water due to COVID-19

She was surprised to find out her home had a public lead service line (LSL) delivering water from the city’s water mains — especially because she was pregnant while living there. “I freaked out,” Cohen says. “I called the city immediately, and I think they actually told me that they weren’t even sure if they could check our pipes, because I think it was the end of their cycle.”

Liberal MPs call on Ottawa to tackle ‘national public health crisis’ of lead in drinking water

Liberal MPs call on Ottawa to tackle ‘national public health crisis’ of lead in drinking water

A group of federal Liberal MPs are asking their government to invest up to $400 million to combat the “health crisis” of lead-contaminated drinking water which was exposed in communities across the country by a national investigation by 10 media outlets, including Global News and the Toronto Star. An open letter written by Hamilton MP Bob Bratina says the government “can and must” direct a portion of infrastructure spending designed to revitalize the post-COVID-19 economy into the “national public health crisis we face in the form of lead-contaminated drinking water.”
