Well, Tony, you raise a very good point. We can only say that we would HOPE municipalities used reputable third party testing agencies (which we believe they must) to perform the required testing. At some point SOMEone in the equation must have the values required to tell the truth if problems exist with a city’s water.

Assuming you can trust the water report…

Let’s say that the water reports we receive each year do tell the truth and all the reports say our water meets or exceeds Federal, State and Local guidelines for water quality — and we believe the reports accurate and factual. Does that mean we all have safe, clean drinking water coming out of our faucets?

Not by a long shot, unfortunately. Our tap water may have left the water treatment plant in perfect condition but before it reaches our homes it must travel through many miles of mixed composition plumbing (i.e. PVC, copper, cast iron, etc.) that may have gotten installed well before health regulations outlawed the use of heavy metals like lead in the solder used to connect pipes.

This means the crystal clear water produced by the water treatment plants could have picked up some unwanted drinking water contaminants along the way even though the political folks who wrote the annual drinking water quality reports told the truth, the whole truth, and nothing but the truth.

Does this mean everyone needs a water filter?

While water filter manufacturers would LOVE for everyone to run out and purchase a water filter for their home, not everyone really does need a water filter. In fact, the vast majority of people on public water systems do NOT need water filters and have them merely for aesthetic reasons (i.e. removal of chlorine taste, removal of chlorine odor, etc.).

So… Should YOU have a water filter in your home? You will not know until you test your water — and of home drinking water test kits range from basic (4-in-1 City Water Check tests for pH, total alkalinity, total hardness, and total chlorine) to slightly more advanced (SenSafe Water Quality Test Kit tests for 14 water quality parameters).

Which water test kit will work best for you?

We have found that most people who draw their water from a municipal source typically can get by with total hardness testing, metals testing, pH testing, alkalinity testing, total chlorine testing, and/or coliform bacteria testing.

This does NOT mean, however, that some municipal water quality situations will not require more advanced testing for VOC’s and other drinking water contaminants.

Already know what you want to filter out of your water?

Next step: Determine which type of filter will work best for your application and where you want to install it (i.e. countertop, undercounter, whole house, on the shower head, on the faucet, etc.). Each location has benefits, but understand that each also has drawbacks.

So, before you plunk down you hard earned cash on a water filter for your home, school or office, make sure the type of filter you choose will do what you want it to do!

In both cases, and so many more, we would suggest getting a test kit such as the Water Quality Test Kit made by SenSafe or the City Water Test Kit made by WaterSafe… and doing some preliminary testing of their own.

In most cases people complaining about city water will have problems caused by contaminants such as dissolved metals (i.e. lead, iron, copper, etc.), chlorine content (free and/or total), total hardness (calcium and/or manganese), and/or rotten egg smells caused by dissolved hydrogen sulfide.

If you get unusual or questionable results, definitely seek the services of a certified water testing laboratory; preferably one not affiliated with a water filter system distributor.

What about bacteria?

We also get asked quite often about the likelihood of harmful bacteria showing up in tap water. Despite the efficiency of modern water treatment facilities and the exemplary track records most have when it comes to the quality of the water they produce, one must always remember two things:

1) Accidental machinery malfunctions can occur.

2) City water travels through lots and lots of piping before it gets to your tap… meaning it passes over thousands of joints where leaks in the pipes could allow the introduction of dangerous bacteria.

If you suspect for any reason that your water supply may contain bacteria, although home drinking water test kits work well as screening methods, times like this call for the services of a certified water testing lab.

You local health department can suggest a water testing laboratory in your area or you can use a mail order laboratory such as National Testing Labs.

While the Iowa Department of Natural Resources says they do not believe any dangerous water safety issues avoided detection, the fact that a city employee responsible for testing the city’s public drinking water supply on a regular basis purchased only enough supplies for 100 tests — despite claiming to have performed 3,889 water tests between January 2006 and July 2009 — would make just about anyone curious.

A former Edgewood city employee has been sentenced to probation after he admitted that he failed to test the town’s water supply and submitted false reports to the Iowa Department of Natural Resources.

…

Harris, 43, pleaded guilty in April to one count of making false statements in a matter within the jurisdiction of the Environmental Protection Agency.

In the plea agreement, Harris admitted he sent false monthly reports to the DNR from February 2008 and July 2009. He falsely claimed testing for fluoride, chlorine and manganese. DNR tests showed less chlorine in the water than the 1.5 milligrams per liter required by state law to kill bacteria.

The review found lower-than-acceptable levels of fluoride, which reduces tooth decay, and manganese oxide, which helps remove cancer-causing radium from the water. Residents in the eastern Iowa town were not exposed to any short- or long-term health risks, a DNR officer said.

The DNR originally alleged that Harris claimed to have done 3,889 water tests between January 2006 and July 2009, but bought enough material for only 100 tests. Harris resigned in August 2009.

The investigation began after some residents complained about declining water quality. ( source )

OK, now having read that, does the statement, “DNR tests showed less chlorine in the water than the 1.5 milligrams per liter required by state law to kill bacteria.” make you feel… safe?

How about “The investigation began after some residents complained about declining water quality.” Does that give you any sense of security?

Can individuals test their city/town/tap water?

Of course they can! While only certified water testing laboratories can give the absolute last word on the safety and potability of drinking water, at-home drinking water test kits from companies like SenSafe and WaterSafe allow the average homeowner to test critical water parameters on their own, whenever they want, and for little money.

What water parameters should homeowners test?

Given the number of possible drinking water contaminants, the average homeowner would find it difficult (and expensive!) to test for them all… but as a general rule, if typically makes sense for people on city/town/tap water to test for water parameters such as:

• free chlorine residual
• total chlorine residual
• lead in water
• copper in water
• iron in water
• total hardness
• bacteria in water
• hydrogen sulfide

Should homeowners with city water test for other things? That all depends on where their water company gets its water. As an example, if the water comes from a well, other potentially harmful water contaminants such as pesticides and arsenic could find their way into the water supply and an ill-equipped water treatment facility may not have the proper technology installed to remove them.

As always, though, if you have serious reason to suspect that your tap water has ‘issues’, seek advice from certified water quality experts. Home water test kits serve as great field tests, but the final word regarding a water supply’s potability should come from a certified water testing laboratory.
