Easy Solutions To Test Your Home’s Tap Water For Contaminants

0

Here’s something you might find unsettling: Our local water companies in the United States are required to meet strict water quality standards put out by the Environmental Protection Agency (EPA). Yet studies by various health and environmental groups have found that we still have a high volume and broad variety of pollutants in our drinking water.

How is this possible? The reasons are infuriating.

For starters, not all water companies comply with the EPA requirements. Perhaps it’s cheaper to just pay the fines than to install the necessary equipment? Or perhaps it just takes too much time to fix everything? Your guess is as good as mine.

The EPA also doesn’t test for, or regulate, every possible contaminant that ends up in our water supply. With countless new chemicals introduced to manufacturing every year, I imagine this would be a somewhat impossible task.

However, there are known toxins (perchlorates, were an example) that seemingly do not make it onto the EPA’s test list until they are pressured to do so by the National Resource Defense Council (NRDC) or other health or environmental group.

In addition, it was found that not all water safety tests are done properly and/or are not reported to the EPA as they should be. Sheesh!

Protecting ourselves

If we can’t rely on our local water suppliers and governments to ensure we have clean drinking water, then we have to take steps to protect our families and ourselves. Thankfully there are several ways to purify our water, each covering a variety of pollutants.

The hard part is knowing which contaminants you face and then matching them to the right purification system, all at a price you can afford.

To find out what’s in your water, you might start with reading the most recent annual report put out by your local water company. These reports are typically included with your water bill once per year, or you can find the report on their website.

Personally, I find some aspects of the report difficult to interpret; however, it’s still worth a read. Here’s an example of the Consumer Confidence Report from my district, to give you an idea (see pages 5 through 8).

Testing the water

There are essentially 3 options when it comes to testing your water.

  1. Hire a professional
  2. Buy a few DIY kits
  3. Get professional lab testing, using DIY kits

The blended solution of professional lab tests, using a DIY kit will make the most sense for most folks from both a practical and cost standpoint. Still, let’s take a quick look at each.

1. Hire a Professional

To avoid having to do all the research and testing on your own, you might call an experienced water tester in your area. The EPA offers an easy to use database to find a certified water testing facility near you. Or you can simply Google “test my water”+ your city or zip code to find testing facilities nearby.

Either way, an experienced professional that is already familiar with your city should know what questions to ask, in order to determine the type(s) of tests to run. And they should know what typically affects homes in your area (for both public and private water systems), which will further help to inform their (and your) choice of tests.

That said, professional testing can be expensive. And, since the bread and butter for these companies tend to be large industrial customers, they don’t always give lower-paying individuals the attention or thoughtful answers they need.

Some companies do offer free testing. However, be aware that these tests are often a vehicle to sell their treatment plans, which means there may be some conflict of interest.

2. DIY water testing kits

If you want to run a preliminary test yourself to see whether professional testing is warranted, or for some quick peace of mind, you’ll find tons of affordable kits on Amazon or at your local hardware store.

There are a few things to be aware of if you go this route. First, different kits test for different things, so you will likely need to buy more than one kit to cover your bases. Plus, you’ll need to know what is commonly found in your area, so you know which tests to choose in the first place.

Finally, the kits are intended to give general results, so they rarely have the specifics you need in order to remedy the issues you find. For example, the kit may tell you that you have heavy metals in your water, but not tell you which ones. More detailed results would require the more expensive professional testing.

3. Professional lab testing with a DIY kit

This third option sits somewhere in between professional testing and DIY kits. I found a pretty cool company, called Tap Score, that was founded a few years ago by a smarty pants grad student from the University of California, Berkeley.

Tap Score is an affordable service for easy home water testing and analysis. It’s more expensive than the individual kits you’d buy on Amazon, but not prohibitively so. And the reporting and recommendations you get from Tap Score are as detailed as what you’d get from a professional tester, but far easier to read and understand.

Here’s how it works.

They send you a simple kit with a few vials. You fill the vials with your city tap water or well water, and then pop the vials back in the mail, using the packaging and postage included in the kit. The whole process takes all of 2 minutes.

About 10 days later, they send you an easy-to-read report about your water and any local environmental water hazards, along with an objective* recommendation on purification systems to help your specific water issues.

* I say “objective” because Tap Score does not sell (or partner with) water treatment solutions. They are 100% focused on testing, so there is zero conflict of interest.

What contaminants might you find in your water?

The type of pollutants you find in your water will depend on a number of factors including, but not limited to…

  • Whether you live near a manufacturing plant, sewage treatment plant, mining operations, gas and oil production facilities, factory farms, nuclear facilities, or other industrial sites
  • Whether you get your water from the city or from a well
  • The type and age of the pipes and plumbing fixtures in your home

In addition to the above, storm runoff, leaky septic systems, people flushing unused medications or recreational drugs down the toilet — this and more can contaminate your water.

While you can often smell and taste contaminants in your drinking water, you can’t always tell which contaminants they are. Plus many contaminants – lead and arsenic, for example – do not have a detectable smell or taste, so you may not realize they are there.

Common pollutants that make their way into our drinking water, even after being processed by the local water company may include:

  • Lead – from your home’s pipes and plumbing fixtures
  • Arsenic – naturally occurring from arsenic-rich rocks and soil, volcanic activity, and forest fires; and human activity from manufacturing, mining, improper disposal of paints, etc.
  • Farming chemicals – fertilizers/nitrates, pesticides, herbicides, etc
  • Pharmaceuticals – antibiotics, antidepressants, anti-anxiety meds, painkillers, hormones
  • Perchlorates – these are widespread, dangerous, and, until recently, not regulated by the EPA
  • PFAS (perfluoroalkyl) – chemical compounds used to make non-stick cookware, paper and packing products, firefighting foam, carpets, leather, and water-repellent textiles
  • Pathogens – viruses, bacteria, and parasites in a water supply that hasn’t been properly treated
  • Cleaners – Ammonia, chlorine, and by-products of the local water chlorination process
  • Fluoride – added ‘for our dental health’. (We can debate whether or not fluoride is a contaminant some other time.)
  • Radioactive materials – from oil and gas production and/or naturally occurring
