Well Water Testing in Michigan — Quick, Easy & Affordable

Water Testing Blog — Wed, 09 May 2012 13:03:55 +0000

We absolutely love finding out that local health officials and water quality experts in areas have banded together to provide low-cost testing to local residents. Today’s water testing good news came to us from Michigan where residents of Antrim, Charlevoix, Emmet, and Otsego counties can take advantage of two different testing packages for nominal fees.

Is your well water safe?

It may look crystal clear, but don’t let that fool you; contaminants could be lurking.

The only way to know for sure if your home’s drinking water is safe is to have it tested.

The U.S. Environmental Protection Agency recommends having well water tested every year, and the best time to do so is now, in the spring after a few rainy days.

“Unlike public water systems, there are no water quality monitoring requirements for private wells, and many never get tested,” said Scott Kendzierski, director of environmental health services for the Health Department of Northwest Michigan. “It is up to well owners to make sure their drinking water is safe for consumption. Fortunately, it’s easy, quick and inexpensive to test drinking water.”

The local health department offers two types of well water testing kits for a nominal fee. Both kits are available the department’s offices in Antrim, Charlevoix, Emmet and Otsego counties. The kit, which tests for the presence of E. coli and other bacteria, costs $16; and the kit that tests for fluoride, chloride, hardness, iron, sodium, sulfates and nitrites is $18. These are small prices to pay to assure your family’s drinking water is safe. ( source )

So, for less than $40 residents of Antrim, Charlevoix, Emmet, and Otsego counties in Michgan can have their water tested for coliform bacteria (including E. Coli), fluoride, chloride, hardness, iron, sodium, sulfates, and nitrites. We consider THAT a really great deal!

OK, but what about everyone else?

If you live close to those counties but not actually in any of them, the article concludes by saying, “For more information about well water testing, visit www.nwhealth.org or call your local health department office.” — and we could not have said it any better than that.

Looking for test kits for home use?

Although all of us at Water Testing Blog highly suggest that private well owners get their water tested annually by a certified water testing laboratory such as National Testing Laboratories (see what they test for) or one recommended by your local Health Department, if you would like to test your own well or ground water we can definitely point you in the right direction.

The Water Testing Blog Store carries a variety of useful test kits for home water testing. Below you will find some of the more popular kits we carry:

Water Softener for Mobile Car Wash

Water Testing Blog — Tue, 10 Apr 2012 17:52:16 +0000

We get all sorts of interesting questions and today’s question involves a man’s interesting starting a mobile car washing business for car dealerships and softening the water he would use in his operation before using it.

“I want to start a mobile car wash for car dealer and i thought if i used a water softer i could cut the time by not drying them .with a softer it would not leave spots would that be a true statement or ? thank you .”

Saltless Water Softener
with 4 Stages of Filtration

Believe it or not, ‘Rob’ posed a rather interesting question: Will removing all, or most, of water hardness eliminate water spots and possibly prevent him from needing to dry the vehicles her washes?

We suspect not since water softeners will usually only reduce/remove calcium and magnesium levels in water… and water may contain other items that could wind up as ‘spots’ on a car not dried in a traditional manner.

Additionally, we believe some spots seen in recently washed cars may have resulted from ingredients in the soaps, detergents, cleaners, etc. contained in the car wash concentrate added to the water.

Oh, and let us not forget that airborne dust, pollen, etc. could very easily land on a recently washed car and find itself attached to the surface as the water droplet it landed in evaporates.

So, while softer water could certainly reduce the harshness of the appearance of water spots, we do not believe it will totally eliminate the need for drying vehicles after washings.

Have you looked into the different types of car cleaner concentrates available on the market these days? We seem to recall hearing about several that claim to leave fewer water spots than other brands. We don’t recall the exact brands, but the ones below seemed to have good reputations.

Water Softener That Does Not Use Salt?

Water Testing Blog — Wed, 04 Jan 2012 01:42:15 +0000

Today’s inquiry came to us from ‘Mike L’ who asked about ways to soften his water without having to use a salt-based softening system.

I live in a small twin (3 bed/1.5 bath) that I lease. When we moved in, we noticed the water was particularly hard (10 GPG) and it was causing dry skin after showers and other issues. We don’t use a lot of water and we don’t have much space (1,300 sq. ft.). I also don’t much prefer the saltiness of “softened” water. My landlord gave me the OK to install a simple filtration system. I’m looking for something cheap, compact and simple. I don’t need 0gpg either, if I can lower down to a 3-4 GPG I would be happy.

Seems simple right? I was thinking maybe a 400GPD RO system but they all come with faucets which makes me think they may not be usable to throw in-line on the water system.

Do you know of anything (under $1,000) I can do to clean up my water and make it just a little softer?

Good news, Mike! Recent developments in the water softener industry include water softeners that do not use salt as the primary treating agent. Reasons for the salt-free water softeners range from States like California putting a ban on them for environmental reasons to people (like yourself) simply not enjoying the taste and/or texture of the water produced by salt-based water softeners.

Eagle A1000AS Anti-Scale Saltless Water Conditioner

To the left you will see an example of a water softener that uses a special filtration media to remove calcium and magnesium from source water instead of salt. The unit also comes equipped with a sediment filter, solid carbon block filter for VOC’s (volatile organic compounds) and an Ultrafiltration Filter good for removing particles as small as .01 microns.

Mike, you mentioned reverse osmosis as a possible option and based upon what you said you wanted from the water treatment system, we don’t think that will work out as well as you’d like, though we do agree that reverse osmosis water filter do an excellent job of filtering water.

Reverse osmosis units do not connect up as inline filters as neatly and tidily as it sounds like you’d prefer. They require drains for ‘waste water’ that gets rejected by the membranes and flushed out during backwashing. Also, reverse osmosis water filters require power which means running a power line to the unit.

The Eagle A1000AS Anti-Scale Saltless Water Conditioner uses no power, requires no drain, uses no salt or environmentally harmful chemicals, and supposedly will help to remove existing calcium and magnesium deposits already clogging water lines.

Moral of the story?

Mike, we suggest having your water tested by a certified laboratory in your area or having a mail order service such as National Testing Laboratories perform a thorough analysis of your water. From the sounds of things, your faucets could possibly have more than just calcium and/or magnesium coming out of them and you will not know for sure until you test.

How Can I Check to See if My Water Filter is Working?

Water Testing Blog — Sun, 02 Oct 2011 13:33:38 +0000

Anyone that has taken the initiative to install a water filter or water purification device/system in their home deserves a bit of praise… and those that continue to take an interest in the quality of their water after installing a water treatment system deserve even MORE for their efforts.

As an example, ‘J. Mampilly’ from India installed a system and now seeks to determine if he has installed the correct unit. He asked,

I would like to know about how i can confirm the effectiveness of my water purifier. Labs in India that can certify and throw light on the camparative quality of water before and after using a water purifier. Thank You

Unfortunately we do not have familiarity with water testing laboratories in India and cannot directly assist with this situation. We can suggest, however, that you contact your local health department and ask them for a list of certified water testing laboratories in your area.

Coliform Bacteria Test Kit

Before…

In order to know what type of filter or what filtering capabilities you should purchase, invest (yes, we said invest) in a thorough water analysis performed by a qualified water testing laboratory. Here, again, we suggest contacting your local board of health and asking them, for a list of certified drinking water testing labs. Alternatively, or if no labs exist in your immediate vicinity, you can use the services of accredited water testing companies such as National Testing Labs.

No matter what, though, always have your water tested BEFORE deciding on a water treatment system. Oh, and one more thing: Don’t think for one second that a salesperson doing an in-home water test has the same water testing tools or qualifications as a reputable water testing laboratory. Remember: 99% of all salespeople attempt to sell things and not accurately analyze a situation — especially if accurately diagnosing a situation could cost them a sale!

Simple Test Kit for
Total Dissolved Solids

And after!

As ‘J. Mampilly’ has done, we should ALL take an interest in comparing the quality of water that comes out of our water filter systems. Only then will we know if the money we invested in (not spent on!) a quality drinking water filter system performs as expected.

Testing water quality beforehand gives us not only an idea of what we need to filter out of our water, but also a checklist of water quality parameters to monitor post-filtration. Should follow up water testing reveal that these ‘issues’ did not get corrected or suddenly show up months after the installation of a water system, perhaps the water filter has stopped working or never really worked properly in the first place and needs service of some sort.

And in conclusion…

Many people go through life ‘deaf, dumb and blind’ when it comes to the quality of their water — until an (initially) unexplainable health problem pops into their life. Then, and unfortunately sometimes too late, those same people get very interested in the quality of their water and want to punish or otherwise penalize others for allowing them to consume tainted, polluted and/or contaminated drinking water.

Although we feel much sympathy for the victims of poor quality drinking water, most of us here in the United States have the ability to at least once every great while perform basic testing for critical water quality parameters such as heavy metals (i.e. lead, mercury, copper, iron, etc.), coliform bacteria, pesticides (i.e. atrazine and simazine), chlorine levels (free and/or total), total hardness, total dissolved solids, and many others.

Many times the contaminants in a water supply will have no taste, carry no odor and not appear before the naked eye. Only testing will alert you to their presence.

Electronic Pool Testing Meter

Water Testing Blog — Fri, 20 May 2011 14:06:17 +0000

As usual the warmer weather (in most of the US) has brought out the folks who have questions about pool water and how best to take care of it. Today’s question comes from ‘ActionLassie007′ who asked,

eXact Micro 7+
Pool Testing Meter

“Do they make meters for pool testing that regular people can afford? Last yr our poolguy had a meter and I asked him how much it cost. He told me one thousand and some change. He lie to me so I would not go get one and he loses a customer?”

Wow. Interesting situation, right? Personally we’d have fired the guy for telling an outlandish lie. Yeah, sure, SOME equipment used to test pool water MAY cost upwards of a thousand dollars or more, but would the average pool maintenance person REALLY spend that kind of money? We doubt it.

We suggest, Lassie, that you take a look at the eXact Micro 7+ Pool Water Testing Meter… which costs well under a thousand dollars, by the way.

Readers’ Choice Award Winner

Combining the reliability and repeatability of a photometer w/ the dependability of proven chemistry methods such as DPD (for chlorine testing) and phenol red (for pH testing), the eXact Micro 7+ Pool Testing Meter puts the power of accurate water testing into the hands of the people who need it most: pool owners.

A definite advantage offered by this particular pool meter: Versatility. The pool testing meter tests for 7 critical pool water parameters directly and with the use of a conversion chart and correct reagentstrip it can test for a number of other water parameters, as well.

What comes in pool water test kit?

In the basic kit you will find everything you need to test for free chlorine, total chlorine, pH, calcium hardness, total alkalinity, dissolved copper, and cyanuric acid.

Chesapeake Bay Getting Better, But Still Far From Good

Water Testing Blog — Fri, 31 Dec 2010 13:03:17 +0000

Usually we report about water conditions in a region getting worse but today we proudly announce that we recently stumbled across some news about improved water quality in a region. It feels good to deliver good news every once in a while, ya’ know?

So anyways, an independent environmental monitoring group in the Chesapeake Bay area (Chesapeake Bay Foundation) announced that results of recent water quality testing indicate definite improvements in the bay’s overall condition.

With its crab population rebounding and water quality slightly better, the Chesapeake Bay is showing signs of improvement, the region’s leading environmental group says, but the estuary remains seriously impaired and needs a strict pollution “diet” to ensure its restoration.

The Annapolis-based Chesapeake Bay Foundation upped the estuary’s overall health score by three points in its latest “state of the bay” report, while warning that it remains in critical condition, barely above a failing grade.

“That the bay is getting better is a huge development, but sadly not the whole story,” William C. Baker, the foundation’s president, said in a release accompanying the report. “Dead zones, fish kills and water contact advisories are constant reminders of how far we still must go.” ( source )

Got a body of water in your area that you’d like to keep an eye on? The Chesapeake Bay Foundation probably uses quite a few advanced tools such as multi-parameter meters to measure a wide range of critical water parameters but in all honesty, sometimes using simple tools such as a TDS Meter or Eco-Check, a very popular product which tests for nitrates, nitrites, hardness, total alkalinity, and pH all with a single dip of a test strip and typically costs less than $14.00 for a bottle of 25 tests.

Drastic changes in basic water quality parameters sometimes serve as warning signs that other, more serious water quality problems exist.

Dangerous Levels of Lead Found in School’s Brass Valves

Water Testing Blog — Fri, 26 Nov 2010 13:03:11 +0000

Since we started this blog articles about ‘new’ dangers posed by lead in water have come up from time to time… and we have posted articles about them as soon as we became aware of them. Does that make us sensationalists or couriers of messages and news intended to make people cognizant of potential dangers posed by the possibility of lead in their drinking water?

WaterSafe Lead in Water Test Kit

SenSafe Water Metals Test Kit

Manganese in Water Test Kit

You will have to answer that question for yourself, and while you ponder that query, please also take a moment to think about the possibility that any number of manufacturing errors could possibly result in the improper distribution of lead in brass fittings — as alleged by researchers investigating alarmingly high levels of lead found in water produced by water fountains after technicians took several steps to make them lead-free.

Hidden elements in drinking-water lines can shed large amounts of lead, a toxic heavy metal. And it’s quite legal, even if it does skirt the intent of federal regulations.

University researchers, who uncovered this problem the hard way, have published a case study on the offending hardware in the November issue of the journal of the American Water Works Association.

Lead adds ductility to brass, making it easier to bend or machine into desired shapes. To limit the risk of lead poisoning, U.S. law prohibits new brass plumbing parts in drinking water lines from containing more than 8 percent lead by weight. Yet two shut-off valves containing only about 6.5 percent lead leached toxic amounts of the metal into drinking fountains at the University of North Carolina.

What happened: During manufacturing, the lead did not uniformly distribute throughout the brass, but ended up preferentially settling at or near the surface. As a result, the outside of affected valves—the side visible when looking at a water line (see photo)—slightly exceeded the lead limit. That shouldn’t have posed a health problem, since this surface doesn’t touch water. However, the valves’ interior surface, which does, contained at least 18 percent lead by weight. ( source )

After reading that, and seeing how careful steps taken by knowledgeable people failed to get rid of all the lead in the plumbing of water fountains on a college campus, would you still think us alarmists by giving the topic a few minutes of publicity?

What levels of lead in water pose a danger?

The United States Environmental Protection Agency has ruled that public water systems may not contain more than 15 ppb of dissolved lead and that any system found to have that amount or greater in the water it distributes must take immediate steps to remedy the situation.

Total Hardness
Water Test Kit

While that sounds like a great plan, the fact remains that pretty much all lead found coming out of faucets in people’s homes entered the water at some point after the water left the water treatment facility. Old water service lines, fittings in people’s homes, and older solder used to join pipes all could contribute lead (and other metals) to the water they come in contact with — especially if the water has aggressive tendencies.

Aggressive tendencies? Water can have a bad attitude and start fights? Well, no, but throwing water on someone in a bar or dance club will put them in a bad mood and possibly start a fight.

When we say water has aggressive tendencies, we mean it has low total hardness and/or a low pH; both of which would make the water want to pull elements (metals and other things) out of any surfaces it comes in contact with.

And in conclusion…

Enough evidence exists out there pointing to the fact that dissolved metals in water have a probability of causing health problems that we do not know WHY anyone would not want to test their drinking water (note: tap water and well water can both can contain dangerous concentrations of dissolved metals) for the presence of metals periodically.

Should You Test Your Water If You Have City/Municipal Water?

Water Testing Blog — Thu, 18 Nov 2010 13:03:46 +0000

We get asked this a LOT. Quite a few people write in ask things like, “I have city water, but it tastes funny. Should we test it?” or “The water in my town tastes different on different days. Is that a problem?”

All-in-One Water Test Kit

Water Quality Test Kit

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 All in One 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.

Water Filter Pitchers and Temperature

Water Testing Blog — Thu, 14 Oct 2010 13:03:20 +0000

Everyone loves the taste of fresh, clean filtered drinking water, but not everyone likes their water ice cold or as cold as it gets when stored in a refrigerator. How do we know this? Simple: Martha wrote in and asked,

I’m thinking of getting a water filter pitcher. Must it be kept in the refrigerator in order for the filter to work? I prefer room temp. water.

Thanks, Martha

Hot Water Filter Housings

We knew that hot water posed a problem for certain types of filters and filter housings — hence the need for special hot water filters & housings — and we knew that frozen water would not work all that well, either (obviously!), but as for whether or not a filter would perform all that much differently at room temperature versus the temperature of a refrigerator, we never gave that a whole lot of thought.

Crystal Quest Pitcher Filter

Until now.

Our quick research has determined that water filter pitchers ought to work just as well at room temperature as they would in a refrigerator. We do, however, suspect that one could possibly need to replace the filters more frequently since warmer temperatures in the filter would make an excellent breeding ground for bacteria. We suspect that water pitcher filters that use certain blends of KDF Media may prove more resistant to bacterial growth than filters that do not use KDF Media.

The Crystal Quest Pitcher Water Filter does something that similar products made by other leading water pitcher filter manufacturers do not. It uses a total of FIVE stages of filtration.

Crystal Quest Pitcher
Replacement Filter

A one micron sediment pre-filter takes out dirt, rust, sediment and any other large particles.
In filter stages 2 & 3… Blends of KDF55 and KDF85 resin media reduce dissolved metals (i.e. iron, mercury, copper, nickel, chromium) and harmful bacteria. As we mentioned before, KDF resin media also has properties which help to prevent the growth of bacteria in the filter.
In the fourth stage of filtration a bed of ion exchange resin further reduces heavy metals including lead, copper and aluminum. This stage also reduces water hardness (calcium and magnesium).
The fifth stage of filtration contains granulated activated carbon (GAC) reduces chlorine (99.9%), bad taste and odors. It also reduces pesticides and chemicals that science has linked to increased cancer risks in humans (i.e. VOC’s, benzene, TTHMs and toxaphene).
