Is the water flowing through your home or office as “pure” as you think? Don’t be so sure.
For thousands of homeowners across Irvine, Ca., and surrounding areas, the reality of what’s in their tap water is shocking- and it’s hiding in plain sight.
If you’re one of the many who believes that your tap water’s crystal clarity means it’s safe to drink, you could be in for an unpleasant surprise.
Recent findings have shown that harmful chemicals and contaminants often slip right through standard filters, and the consequences may be affecting your health and home every day.
If you’re not taking additional measures, you could be missing out on the full picture of what’s flowing through your pipes.
It’s easy to assume that clear, odorless water is clean. But a closer look often reveals chemicals, minerals, and even bacteria that can take a toll on your health over time.
From chlorine used in water treatment to naturally occurring contaminants like lead and arsenic, the list of invisible toxins can be unsettling. And as research advances, more of these hidden dangers come to light- many of which aren’t caught by basic household filters or municipal water treatment.
Water experts at McCowin Water have seen it all. In hundreds of homes throughout Orange County, our team has discovered shocking results, uncovering contaminants that homeowners had no idea were lurking in their water.
With over 500 5-star reviews, our free in-home water analysis is opening eyes and giving families a fresh look at what they’re drinking, bathing in, and cooking with every day.
So, what does this mean for you? It means that without this analysis, you may be unknowingly compromising your home’s water quality-and your health
