In the United States it is estimated that only 10% of plastic bottles are recycled. Meanwhile the bottled water industry has grown into an $8 billion dollar behemoth by selling us something we already have access to, drinking water.
You might think that this would have caused some public uproar by now, after all, the evidence points to a bit of foul play on the part of many companies that sell bottled water. Bottled water has become the wolf in sheep’s clothing purporting itself to be a helpful part of a healthy lifestyle. Pepsi famously created this 60 second add spot to promote their Aquafina brand in which drinking bottled water fills an entire bar with physical health and good feelings. Read More
I wanted to take a look at point of use drinking water filters. A standard filter housing is compatible with hundreds of 10 inch replacement filter cartridges so you have a lot of options on what to use.
Carbon based filters rely on activated carbon to remove impurities from water. Activated carbon filters attract dissolved chemicals causing them to stick to the carbon surface as the water passes through the filter. This is often referred to as the adsorption process and effectively removes chlorine, particles and volatile organic chemicals (VOCs).
So when it comes to drinking water you should definitely use a carbon based filter cartridge to remove chlorine and other chemical contaminants. Read More
Let’s start by setting aside a couple of myths about the fluoride being added to your drinking water.
1. It is not part of a vast government conspiracy to control the human population.
2. It will not prevent cavities from forming by itself (sorry kids, you still have to brush your teeth)
So what does it do and why did they start adding fluoride to our drinking water? The simple answer is that a government health review of fluoridated water shows that it helps reduce tooth decay by as much as 60%. Dentists used fluoride treatments to help fight cavities, but that only worked for the people who could afford regular dentist visits. Read More
It has already happened in parts of the country and more water utilities may switch over to a new chemical treatment for drinking water. Chloramine has been used as a disinfectant since the 1930s, but many water utilities still primarily use chlorine treatments. The San Francisco Public Utility Commission recently made the switch in part because chloramine is considered to be more stable than chlorine for water treatment.
One of the drawbacks of the switch is that chlorine can be boiled out of water and will dissipate on standing, but chloramine will not dissipate in water. Water treated with chloramine should not be used for kidney dialysis machines or for fish tanks unless it is treated with a water filter first. Read More
A water quality study done in Sonoma County, CA by UC Berkeley showed that the elderly tend to be less tolerant to contaminants in drinking water. Sonoma County was targeted by the study because it meets all the Federal standards for water quality. Basically the water is “safe” to drink by government standards.
The study shows that the older residents were 12% more likely to experience more severe gastrointestinal illnesses. While 12% may not seem like much it is statistically significant because it lies outside the range of normal deviation. So while Federal standards are “safe” for most users, there is still a risk to people with weaker immune systems because trace levels of contaminants remain in drinking water. Read More
Congress has given the EPA a mandate to perform a full investigation of the practice of using ground water mixed with chemicals to release oil or natural gas, known as fracking, from drill sites.
The main concern with this process is its possible chemical contamination of ground water and the problem of proper disposal of waste-water. The EPA will be focusing their study only on the effect fracking has on drinking water and expects to have a plan in place by March 7-8 of this year.
Though there has yet to be a conclusive study that shows fracking has contaminated drinking water there have been more than 1,000 reports of contamination where drilling is the suspected culprit. Read More
You can imagine my surprise when I found out that the chlorine that is used to disinfect many swimming pools and most public water supplies can cause an unsafe level of chlorine inhalation. I suffered from asthma symptoms for years growing up and in the summer time spent hours at the neighborhood pool.
Exposure to chlorine is not in itself that dangerous, but if you already suffer form allergies or asthma it certainly can aggravate your symptoms. Studies are also being conducted that indicate that prolonged exposure to chlorine can lead to an increased risk of developing asthma in children. One of the primary sources of chlorine exposure actually comes from showering as most water utilities use chlorine to disinfect water to remove harmful bacteria. Read More
This should not come as a surprise as more and more chemicals being studied by researchers have been found to have potentially harmful effects on humans. For information from the EPA press release click here.
Some of the latest contaminants targeted for regulation are perchlorates, a chemical that is produced naturally and increased from man made interference, and can effect hormone levels in pregnant mothers. Studies have shown that perchlorates can interfere with the thyroid gland and this is the main reason it is being regulated.
The EPA has decided to address 15 others contaminants at the same time, they usually only tackle 1 chemical at a time, in an attempt to make it more cost effective to enact regulations for safer drinking water. Read More
