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)

Most of us take for granted that we will have safe, clean tap water coming out of our faucets and think nothing of the dangers presented by not filtering and/or purifying our water prior to use.

• Cryptosporidium, a gastrointestinal parasite, contaminated the municipal drinking water of Milwaukee, Wisconsin in 1993 and caused one hundred deaths. ( source )

• A deadly strain of e.coli bacteria found its way into the municipal water supply of Walkerton, Canada in 2000 causing hundreds of residents ill and eventually taking the lives of seven people. ( source )

It sounds shocking that such horrible water quality tragedies could happen in modern times given the frequency of municipal water testing, but two very important facts stand out if you take the time to think about the way in which municipal water systems operate:

1. Municipal water systems test for a set number of water quality parameters and sometimes rare, unusual, and often not-tested-for water vermin like Cryptosporidium can easily slip past even the most stringent water testing programs. Example: Milwaukee, WI in 1993.

2. Municipal water systems test water at the point of distribution, not use. This means the water leaves water treatment facilities fully tested and approved for consumption… but keep in mind that the water must travel through many miles of piping and plumbing with literally thousands of joints and welds where harmful contaminants could find their way into the water if only one of those places has cracked or otherwise become deficient.

So as you can see, even the best water treatment plants in the world with the best records for drinking water quality cannot issue a 100% guarantee that your tap water will contain no unwanted contaminants. Once water leaves their grounds its quality can change for innumerable reasons and in innumerable ways… so ultimate responsibility for making sure you have safe, clean tap water falls on… your shoulders.

Installing the correct point-of-use water filtration and/or purification system (i.e. countertop, undersink, whole house, shower, etc.) can negate pretty much all the possible risks associated with water contamination between the distribution point and your favorite glass.

Take the time to learn about the different point-of-use water treatment options you have available and, of course, don’t forget to test your drinking water periodically, even after installing a filtration/purification system, to make sure it continues to function properly!

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.

We recently read that the Federal Government has decided to investigate the severity and cause elevated nitrate and bacteria levels in well water out in the State of Washington.

From the sounds of things, the situation has gone on for quite some time… and residents in rural Lower Yakima Valley may have had elevated nitrate and bacteria for quite some time now w/o anyone really looking into where the contaminants came from.

Stories like this one ought to make EVERY private well owner seriously consider having their water tested by a certified water testing laboratory and performing routine checks themselves with at-home well water test kits — because the responsibility for the safety of private well water rests solely with well owners.

YAKIMA, Wash. — An effort to address polluted groundwater consumed by many rural Lower Yakima Valley residents was formally launched Thursday as local, state and federal officials pledged to tackle a stubborn problem that’s been decades in the making.

“It’s going to be a big challenge. It’s a difficult problem,” said Tom Tebb, regional director for the state Department of Ecology in Yakima.

“But it matters because we have people drinking water contaminated by nitrate and bacteria and at unsafe levels in some cases,” Tebb said at a news conference to announce the effort.

Five agencies released the final version of a report on groundwater quality that is a wide-ranging compilation of historical data about the contamination, health effects, regulatory responsibilities and recommendations for action.

…

Of some 30,000 private wells in the Lower Valley, 20 percent have elevated levels of nitrate and bacteria.

This week, federal regulators began their own testing program on 150 wells to try and determine the source of the nitrates and bacteria.

To make sure the samples are tested in a timely fashion, a mobile laboratory has been driven to Yakima from Manchester, Wash., on the Kitsap Peninsula, home of the regional lab for the U.S. Environmental Protection Agency.

Two microbiologists will test for coliform bacteria, fecal coliform and e. coli and conduct “microbial source tracking” to determine if the bacteria are human or ruminant. Cattle are ruminants, and manure from dairy and feedlots is one suspected source of both nitrate and bacterial contamination.

Another round of testing in April will help the agency determine the link between elevated levels of nitrate and sources of nitrate, which can come from manure, chemical fertilizer or septic systems.

If the test results allow regulators to identify obvious sources of pollution, enforcement action could follow, said Tom Eaton, director of the Washington operations office of the EPA in Seattle.

Results are expected sometime this summer. ( source )

If you own a private well and do not have your water tested on a regular basis you run the risk of exposure to an almost limitless number of contaminants that can get into the aquifer at any time and for a number of reasons. Natural disasters, changes in weather patterns, heavy demand from other well owners, etc. can all affect the quality of the water in your well.

Water Tests by a Certified Drinking Water Testing Lab

Short of having the Environmental Protection Agency come out and test your well and/or water, no better option exists than to have your water tested by a certified drinking water testing laboratory like National Testing Laboratories which offers three levels of testing:

Basic Test Kit — Tests for 27 Common Drinking Water Contaminants: Aluminum, Arsenic, Barium, Cadmium, Calcium, Chromium, Copper, Iron, Lead, Magnesium, Manganese, Mercury, Nickel, Selenium, Silver, Sodium, Zinc, Alkalinity, Chloride, Fluoride, Nitrate as N, Nitrite as N, Sulfate, Hardness, pH (Standard Units), Total Dissolved Solids, and Turbidity (Turbidity Units).

Most Popular Test Kit — Tests for 83 Drinking Water Contaminants: Bacteria (presence/absence for coliform and E.coli), (19) heavy metals and minerals, (6) other inorganic chemicals, (5) physical characteristics, (4) trihalomethanes and (47) volatile organic chemicals.

Most Popular + Pesticides — Tests for 83 Drinking Water Contaminants: Bacteria (presence/absence for coliform and E.coli), (19) heavy metals and minerals, (6) other inorganic chemicals, (5) physical characteristics, (4) trihalomethanes and (47) volatile organic chemicals plus an additional 20 tests for pesticides, herbicides and PCB’s.

Since we posted one type of 20″ Big Blue Water Filter, we may as well continue with another type of 20-inch Big Blue filter. This time we have a list of replacement sediment filters from Liquatec, Aqua-Pure and Pentek that will fit into most standard 20″ Big Blue Filter Housings.

Last Summer the Department of Natural Resources in Missouri allegedly delayed releasing the results of bacteria testing in Lake of the Ozarks to keep from having to shut down beaches and other popular waterfront vacation spots during a highly profitable time for the region. Needless to say that when news leaked out that some of the water test results indicated the presence of potentially harmful bacteria, people got upset — and the blame game began.

Two Missouri senators filed legislation on Thursday seeking to strip water quality testing authority away from the state Department of Natural Resources and give it to the Department of Health and Senior Services.

Sens. Brad Lager, R-Savannah, and Kurt Schaefer, R-Columbia, filed the bills the same day that Lager’s office released a draft Senate committee report on DNR’s decision to delay the release of water quality tests that showed high levels of bacteria at the Lake of the Ozarks last summer.

“I don’t have confidence that the department won’t mess it up again in the future,” said Lager, who headed the committee investigating the incident. “And the Department of Health and Senior Services is responsible for public health and safety.” ( source )

The more we hear about this situation, the more things that jump out at us and the more questions we have. As an example, why do people think that taking the water testing responsibilities away from one politically influenced group and handing it to another politically influenced group will make a difference?

Politics and profit run hand-in-hand and no matter WHO does the testing, when the choice between forcing business owners (local voters) to take a sizable loss in revenue or allowing (non-local) people to swim and spend money even though a slight chance exists that they may get sick from a little bacteria, well…. Which do YOU think people whose jobs depend upon political agendas will choose?

Doesn’t seem to matter WHICH agency you choose, the answer will always come out the same: Get that money.

So, in lieu of having incorruptible third party testing done, which would cost too much money and put a lot of people in government agencies out of work, the public must fend for itself if it wants to know the truth about water quality.

Personal Test Kits for Bacteria

• Coliform & E. Coli in Water Test Kit — Test kit confirms the presence/absence of coliform bacteria and, with a fluorescent light source, the presence/absence of E. Coli. Good for Drinking water applications.

• Coliform Bacteria in Water Test Kit — Test kit confirms the presence/absence of coliform bacteria in a water sample w/in 48 hours. Good for drinking water applications
