We drink, bathe, cook, and clean with it. But how much do we really know about the water that flows out of our faucets? Some regions fare better than others when it comes to contaminants, but lead, bacteria, and nitrates can still make their way into water supplies . And recent debates on the potential negative impact of hydraulic fracturing (one way of mining oil and gas trapped deep underground) have brought even more attention to what’s reaching our water supply. So before drinking up, let’s take a closer look at what’s on tap.
Troubled Waters? — The Need-to-Know
Tap water comes from one of two sources: surface water (including reservoirs, rivers, and lakes) or groundwater (from artesian and deep wells). But before it hits our thirsty lips, most H2O undergoes an important disinfection process, destroying most harmful organisms like bacteria and parasites .
But chlorination won’t kill off every bad guy, and some disease-carrying germs can still pollute surface water — and ultimately tap water — through the stool of infected animals or people (ick, we know). Lead and copper can also crash the party via corroded pipes, mostly in homes built before 1970, when copper pipes and lead joints were deemed acceptable. Other less-than-ideal findings: nitrates and other chemicals from fertilizer and pesticide runoff, arsenic (via erosion, orchard runoff, and industrial waste) and evenrocket fuel . And then there’s the alphabet soup of chlorination byproducts — some of the most controversial and potentially harmful contaminants of them all . And while the possible effects of hydraulic fracturing (aka fracking) on drinking water has certainly stirred up debate, we need to stay vigilent!
Still sounds scarier than a Freddie Krueger flick? Luckily, the EPA has established Maximum Contaminant Levels (MCLs) for public water sources, making the chances of catching a water-related illness relatively slim . And with 91 contaminants regulated by theSafe Drinking Water Act, unwanted intruders are capped at concentrations generally safe enough for the average healthy individual.
Tips for Tap — Your Action Plan
While the quality of H2O will vary between homes, there are a few ways to start sipping more soundly. First, contact the local Public Water Supply for a Consumer Confidence Report, and ask about further testing options if data is limited. And in the meantime, consider trying these simple tips to reduce lead (one of the most dangerous but preventable toxins) in drinking water:
- Run It. When a particular faucet hasn’t been used for six hours or more, “flush” the cold water pipes by running the water until it becomes as cold as it will get.
- Drink Cold. For drinking, cooking, and preparing baby formula, always reach for the cold water tap. Hot water is likely to contain higher levels of lead.
- Re-Strain. Routinely clean and replace faucet strainers, which can accumulate debris, metals, and other sediment.
- Take a Sniff. Smell rotten eggs, chemicals, or an earthy or metallic-type odor? Consult this troubleshooting resource — or contact the local public water department if the problem isn’t described there.
THE BEST OPTION?
- Go Filtered. Pregnant women, children under the age of 6, and those with weak immune systems should opt for filtered water to keep harmful contaminants away. This includes getting a whole house filtration system. Even an under the sink option is better than nothing because we need to keep our families safe!
- REMEMBER, IF YOU DONT HAVE FILTERCON, YOU…MAY BE THE FILTER.
