For those who would like a definition of pH and an explanation of why testing for pH matters, take a look at one of our previous blog entries: “Testing for pH Levels and Why pH Matters“.

Since we have not, as of yet, posted a blog entry specifically about alkalinity, we figure we will take care of that matter right now by including a basic definition of alkalinity in this blog entry:

In a nutshell, alkalinity refers to water’s ability to resist sudden changes to its pH and to measure alkalinity we measure the amount of CaCO₃ in the water. In nature CaCO₃ typically comes from rocks and soil that water passes over in its travels.

Pool and spa owners will add CaCO₃, sometimes referred to as “Alkalinity Increaser, to counteract the basic (high pH) nature of liquid chlorine and/or the acidic (low pH) nature of most chlorine tablets and sticks.

Since pH and alkalinity have such a close relationship, and it would make sense to measure one if you planned to measure the other, the makers of the WaterWorks brand of water quality test strips created the pH and Total Alkalinity Test Strip which measures both water quality parameters simultaneously and gives accurate, repeatable results in under 30 seconds.

Directions:

1. Dip 1 test strip into a water sample for 10 seconds, then remove.
2. Immediately match pH color, then match alkalinity test pad color.

Detection Levels:

• pH: 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0
• Total Alkalinity: 0, 80, 120, 180, 240, 360 ppm (mg/L)

We recently learned of another vendor, WaterFilters.Net, that offers drinking water water test kits on their web site.

A while back we posted an article about the extent of mercury contamination in freshwater streams and rivers in the United States and in that article we told you how fish from ALL 291 bodies of water tested came up positive for mercury. Therefore an article which recently appeared on the Denver Post web site about smallmouth bass in the Juniata Reservoir coming up positive for mercury contamination did not surprise us.

How certain government officials proposed to DEAL with the problem, however, DID shock us.

GRAND JUNCTION — A reservoir that provides drinking water for Grand Junction is closed for fishing because smallmouth bass there have tested positive for mercury contamination.

Steve Gunderson, director of the Colorado Department of Public Health and Environment’s water- quality division, says the mercury levels in Juniata Reservoir are extremely low, but mercury accumulates in fish. He says state health officials are meeting with city officials about keeping the reservoir off a list of bodies of water that don’t meet water- quality standards, if they can get rid of all contaminated fish or isolate the reservoir. ( source )

Sounds to use like the officials seem more concerned about keeping this body of water off the ‘contaminated list’ than they do about the actual underlying problem: Mercury in the water!

Granted the article only gave a brief overview of the situation at Juniata Reservoir, but we really find it strange that the proposed method of ’solving’ the problem involves removing (killing) all the smallmouth bass… and/or keeping those fish from migrating to another body of water.

No matter how you look at it, once again it seems that certain government bodies care more about regional revenue from tourism, revenue from sport fishing, and revenue in general than they do about finding the underlying cause of all the problems… and this means, to some extent, that the general public must keep a vigilant eye on issues involving contamination of lakes, rivers, ponds, streams, and any other bodies of water because government agencies have their own agendas which may or may not include keeping toxic materials out of the water.

Testing for Metals in Water

A quick and efficient way of testing for the presence of metals in your water involves the use of a water testing product such as the SenSafe Water Metals Check which provides users with semi-quantitative water metals levels in under three minutes.

SenSafe Water Metals Check requires no iodine indicator solution, no meter, and no specialized training. Just dip the strip for 20 seconds, wait two minutes, and match color on the end of the strip to the color chart provided on the bottle.

Metals detected by SenSafe Water Metals Check include, but are not limited to, copper, cobalt, zinc, cadmium, and nickel.

SenSafe Water Metals Check has a low detection limit of 10ppb (parts per billion), much lower than any comparable product on the market.

What About Testing for Mercury in Water?

Simple test kits exist for testing mercury levels in drinking water as well. SenSafe manufactures two different Mercury in Water Test Kits and both, like SenSafe Water Metals Check, require no meter or special training to use and yield results in a matter of minutes.

Over the past 2 years we have mentioned test strips for commonly tested water parameters such as chlorine, pH, water hardness, bacteria, and heavy metals on a regular basis. Recently someone asked us if we knew of test strips for other, less commonly tested water parameters.

Without knowing exactly WHICH unusual water parameters to look for we just started searching for odd water contaminants and came up with the following:

Tony from California asked…

My wife and I just bought a home and although the real estate agent showed us all sorts of confusing paperwork that supposedly proved our tap water passed all sorts of tests we still have our doubts. We want to do some testing ourselves. What are the most commonly tested water parameters? Thank you.

We will answer that question in two ways: 1) We will ask a water testing and filtration dealership; 2) We will look at this site’s history and see what pages people have loaded most often this month.

IsoPure Water replied to our inquiry by listing the top three selling water test strips: SenSafe Free Chlorine, WaterWorks Total Hardness and SenSafe Total Chlorine.

With regard to the most popular postings on Water Testing Blog, in the month of January 2010 more people looked at these blog entries than any others:

• Hardness: Grains per Gallon vs. Parts per Million
• Testing Chlorine Levels: Drinking Water vs. Pool Water
• Your Baby Needs Safe, Clean Drinking Water
• Free Chlorine, Combined Chlorine and Total Chlorine
• Acceptable TDS Meter Readings Do Not Guarantee Safe Drinking Water

Nitrate: In inorganic chemistry, a nitrate is a salt of nitric acid with an ion composed of one nitrogen and three oxygen atoms (NO₃). In organic chemistry the esters of nitric acid and various alcohols are called nitrates. Nitrogen trioxide is an alternative name for nitrate. ( source )

Nitrite: The nitrite ion is NO₂. The anion is bent, being isoelectronic with ozone. More generally, a nitrite compound is either a salt or an ester of nitrous acid. ( source )

WaterWorks™ Nitrate / Nitrite (as Nitrogen) test strips make in-home and field testing for nitrates and nitrites in water a fast, easy process. This product requires no tablets, powders, or counting of drops… making it well-suited for on-site well testing or the occasional testing of drinking water at home.

Each WaterWorks™ Nitrate / Nitrite test strip performs (1) one nitrate test and (1) one nitrate test.

* Dip strip into sample for a period of two seconds
* Remove strip and wait one minute
* Compare developed colors on test pads to color charts on bottle label

Each bottle of WaterWorks™ Nitrate / Nitrite test strips comes with a total of (50) fifty nitrite tests and (50) nitrate tests.

Detection Ranges:

Total Nitrate (NO3): 0, 0.5, 2, 5, 10, 20, 50 ppm (mg/L).

Total Nitrite (NO2): 0.15, 0.3, 1, 1.5, 3, 10 ppm (mg/L)

We recently learned that Filter Water, an online distributor of drinking water quality improvement and water testing products, has expanded the number of SenSafe Test Kits to include Ida’s Iron, a dual range test strip that can detect ferrous iron levels as low as 0.005 ppm and as high as 50 ppm in under a minute.

Ida’s Iron specifically reacts with (ferrous) dissolved iron (in the +2 state) without interference from other heavy metals such as copper, silver, mercury, lead or chromium.

For applications where fast, accurate field testing for low levels of Fe+2 matters, Ida’s Iron provides a solid solution and allows you to say, “goodbye” to time-consuming wet-chemical kits that may require specialized training or equipment.

Features of Ida’s Iron include low detection range, easy testing procedures, test times under one minute, no need for glassware, and low test reagent concentrations.

Below you will see a sample of the Ida’s Iron color chart and label:

Label & Color Chart for Ida’s Iron

Ida’s Iron Check Water Test Specifications:

• Sensitivity: 0, 0.005, 0.01, 0.03, 0.06, 0.1, 0.3, 1.0, 2.0, 5.0, 10, 20, 50 ppm (mg/L)
• Test time: 45 seconds
• 25 test strips in a package

Note: To test for total iron, you will want to use a test kit such as the Visual Iron Test Kit which detects both ferrous iron and ferric iron.

Every once in a while we get a request for information related to testing pond water and aquarium water. Today we bring news of a product, AquariaTest™ Ammonia, that makes testing the ammonia levels in pond and aquarium water very easy.

Ammonia Aquarium and Pond test strips provide a water quality testing alternative to older testing methods which required the use of chemicals in liquid, powder, and/or tablet form. Ammonia AquariaTest™ also shortens testing times and makes it easy for anyone, novice or expert, to test the ammonia levels in their water.

As an added feature, the AquariaTest™ Ammonia will also work in salt (or brackish) water^*.

How to test for ammonia in fresh water:

• Using supplied pipette, fill one of the supplied vials half full (3 ml) with water.
• Cap vial and shake for 30 seconds
• Remove cap and dip one test strip for 30 seconds with back and forth motion
• Remove the strip and match to the closest color on a chart

AquariaTest™ Ammonia Test Specifics:

• Ammonia Detection Range: 0, 0.2, 1.0, 2.0, 5.0
• Test Time: 1 minute
• Tests per Kit: 25 test strips

^* — Instructions for testing ammonia levels in brackish and salt water included in the test kit.

Although we cannot and will not ever say whether we prefer the WaterSafe brand of home water testing kits or the SenSafe brand of home water testing kits, we can tell you that we have used both extensively over the years and gotten excellent field testing results pretty much every time.

Having said all that, it pleases us to announce the launch of a brand new web site: WaterSafe-Test-Kits.Com. There you will find product details on all of WaterSafe’s most popular water testing kits. You can also access the product pages on the site using the links below!
