Feds Testing Lower Valley Wells for Bacteria and Nitrates

Water Testing BlogBacteria, Coliform, Environmental, Ground Water, Home Water Testing, Nitrate, Nitrite, Water Quality Testing, Water Testing, Well Water

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

National Testing Labs

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.

Question: How Does a Reverse Osmosis Filter Work?

Water Testing BlogArsenic, Arsenic in Water, Copper, Iron, Lead, Metals, Nitrate, Nitrite, Reverse Osmosis, TDS, Water Filter, Water Testing

SusanB wrote us recently to ask a question that many people people have probably asked after reading some of the postings here on the Water Testing Blog, but never bothered to ask anyone at the Water Testing Blog

Your site and many others talk about ‘reverse osmosis‘ water treatment systems all the time but never really explain how they work. Are they just some sort of fancy carbon filter or something? I really want to know because I need to do something about my bad water and if they’re no different, except in price, than a simple carbon filter then I won’t waste my money on one. Can you explain the difference? IS there a difference? Thanks!

Actually, SusanB, we have posted information on Reverse Osmosis Water Filters in the past that addresses most of the questions you asked… :)

And now, after re-reading our own posts we have decided that we really ought to locate and re-post a more user-friendly definition and explanation of reverse osmosis water filtration.

There are a range of water filtration systems available to today’s consumer to meet the different challenges of raising water quality. Often, a simple activated carbon filter does the trick, but many people have more complicated water problems, and find that they need more complex water filtration systems because of this. A reverse osmosis water filtration system will, in many cases, solve these more advanced problems.

Reverse osmosis (RO) water filtration is a multi-step water filtering process which works slowly but is extremely effective. Reverse osmosis systems are generally used to treat cooking and drinking water supplies. It’s often used in industry but works very well in the home. Reverse osmosis uses the principles of osmosis (in which material passes slowly through a membrane and is concentrated and purified in the process) to produce very clean water.

The first step is that a simple sediment filter is installed and all water to be used passes through it; the filter catches large particles of materials such as rust or calcium carbonate (a compound which is not at all harmful but which isn’t desirable in your drinking and cooking water – it’s commonly used as an antacid). Sometimes a second filter of a similar design, but more fine, is used after the initial filtering. An activated carbon filter traps organic chemicals, and then the RO filter, which is a very fine membrane, is used. It may be helpful to think of all these filters as being similar to sieves with differently-sized holes. Basically, the process of reverse osmosis water filtration would be akin to draining cooked food through a series of increasingly-fine sieves, rather than just emptying the pot into a basic perforated colander. Reverse osmosis water filtration systems, being more complex and increasingly sensitive, can trap far more contaminants than just one simple carbon filter. Some RO systems will, even after the water has passed through the RO membrane, use yet another carbon filter or, alternatively, an ultra-violet lamp, to purify the water even further. The result of all of this filtering is extremely high quality water.

Reverse osmosis is not the most efficient of all water filtration systems, and some have expressed concern about the fact that it takes approximately four gallons of processed water to result in one gallon of clear water. However, its effectiveness makes it a preferred water filtration method for many. Some describe it as “ultrafiltration,” which gives a sense of how powerful RO is. RO results in very pure water. The Water Quality Association says that RO filter systems produce water purity levels as high as 95 percent, which is extraordinary.

The fact remains that reverse osmosis water purification systems remove an astounding range of contaminants from your water. Arsenic, barium, cadmium, chromium (hexavalent), chromium (trivalent), copper, lead, nitrate, nitrite, radium 226/228, selenium, iron and TDS are all removed from your water with an RO system.

A reverse osmosis water filtering system is obviously more complicated than a simple carbon-filter water pitcher, but the benefits of its complex design are also obvious. For those who are concerned not merely with the aesthetics of their water – taste – but have more concrete problems with water quality, an RO water filter may be the best solution to your problem.

Well, SusanB, and everyone else reading this, we hope the information above helped you to understand a little bit more about the ways in which reverse osmosis water filters operate and the benefits they offer. Below you will find links to three popular reverse osmosis water filters units available from WaterFilters.Net.

Simple Test for Nitrates and Nitrites in Water

Water Testing BlogNitrate, Nitrite, Test Strip, Testing Devices, Water Quality Testing, Water Test Kit, Well 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 )

Nitrate/Nitrite Test Strips

Testing Water in Ponds, Lakes, Rivers, Streams, Etc.

Water Testing BlogBacteria, Environmental, Nitrate, Nitrite, Water Quality Testing, Water Testing

Ever wonder about the quality of the water in the stream running on the edge of your property where the kids play? How about the water in the pond or lake where you go swimming in the Summer?

If you have not, then you probably don’t know that those bodies of water can sometimes contain high levels of nitrates, nitrites, bacteria, and other natural ‘things’ which can, in the right concentrations, cause illness in animals and humans.

  • Health officials closely monitor water conditions at public beaches for a reason: High levels of the aforementioned naturally occurring compounds, and others, can make swimmers ill.

  • Pond owners monitor the conditions of the water in their ponds for a reason: Too much of the aforementioned naturally occurring compounds makes the water in their ponds toxic to fish… and it costs money to replace fish.

  • Environmentalists pay close attention to nitrate, nitrite and bacteria levels in surface water for a reason: Too much or too little of any may signal the growth or lack of growth of plant and animal-life critical to the ecosystem.

So whether you want to take a dip in the lake, wade out into the river, play in the stream, or raise healthy coy in your pond, chances are you will want to keep tabs on water quality.

Poultry Waste Pollutes the Lake?

Water Testing BlogEnvironmental, Nitrate, Nitrite

In an earlier posting we discussed possible water quality problems caused by runoff from farms raising cows and from fields where farmers spread large amounts of cow manure as fertilizer. This time we bring news of watershed region in Oklahoma allegedly harmed by runoff from a different kind of farm: Chicken farms.

Excessive amounts of nutrients, primarily from runoff from fields where poultry waste has been used as fertilizer, have caused excessive aquatic vegetation, much of it algae, to become a problem in Lake Tenkiller, said Shanon Phillips, director of the Water Quality Division for the Oklahoma Conservation Commission.

Phillips is the first of a long list of scientists who are expected to testify for the state in Oklahoma’s poultry industry pollution lawsuit.

The state claims that 11 poultry companies are legally responsible for the handling and disposal of poultry waste — also known as litter — that the state says has damaged portions of the Illinois River watershed in Oklahoma. ( source )

Now who would have thought chickens (and their waste) could make such a big mess and cause such a problem? At this point the answer to that question really does not matter. The lawyers, judges, government, and big corporations figuring out what to DO about the situation does matter, though.

How does this article about chicken waste affecting a lake affect drinking water and why did we bother writing about the topic? Simple: More people need to take a closer look at the events and things that could impact their water supply.

If more people took it upon themselves to test their drinking water and make their findings public when problems arose perhaps government officials and big corporations would have to take action about situations like excess nitrate, nitrates and bacteria entering the environment before entire ecosystems collapsed or required substantial amounts of time and effort to remediate.

Water Testing Basics for Aquariums

Water Testing BlogAmmonia, Aquarium, Chlorine Testing, Environmental, Hardness, Home Water Test Kits, Nitrate, Nitrite, Total Chlorine, Water Quality Testing, Water Test Kit, Water Testing, pH

Several people have asked why we have not talked about water… in aquariums. No particular reason, really, other than not enough people had asked for that sort of information — until now.

Many people have the wrong idea about how much maintenance and testing a healthy aquarium requires. Notice we said, “healthy.”

An UNhealthy aquarium requires next to no maintenance. Simply add water to the tank, throw in some fish, wait for fish to die, scoop up dead fish, re-stock tank with live fish, and repeat the last two steps until common sense kicks in.

Eventually people catch on to the fact that an aquarium needs more attention than just adding fish and dumping in food once in a while. It takes some people longer than others to figure that out, true, but we can discuss that topic another time. For right now let’s stick to the topic at-hand: Testing Aquarium Water so that your fish don’t keep going belly up.


API Test Kit for Ammonia, Nitrate & Nitrite


Liquid Test Kit for Ammonia, Nitrate & Nitrite


Liquid Test Kit for General Hardness & Carbonate Hardness


Test Kit for Monitoring Copper in Water


Test Kit for Monitoring Iron in Water


Test Kit for Monitoring Phosphates in Water

As you can see from the above test kits, you will have to test for a number different water parameters if you want to keep your fish healthy, happy and alive. Thankfully most aquarium test kits these days come with easy-to-follow instructions and the average person can complete the testing in just a few minutes.

Which water parameters matter most? Hard to say, but many pond and aquarium experts agree that a person ought to keep a close eye on the following water quality parameters if they hope to have clean, healthy water for their fish to live in:

  • Ammonia Levels — As disgusting as it sounds to us, fish live in their own waste products, one of which is ammonia. Excessive amounts of ammonia result in respiratory problems for fish and if left untreated the fish will eventually stop breathing and die.
  • Chlorine/Chloramines Levels — Extremely toxic to fish and pretty much all aquatic life even in small amounts. When adding fresh water to an aquarium, always make sure to test for and remove any and all traces of chlorine and chloramines.
  • Nitrite Levels — When ammonia breaks down it forms nitrites, another very toxic compound which can cause respiratory distress in, and eventually the death of, fish.
  • pH Levels — It ought to come as no surprise that fish don’t want to swim around in extremely acidic or basic water any more than you would want someone pouring hydrochloric acid or concentrated lye onto your skin. One thing to remember, though, about pH: Not all fish prefer the exact same pH so when choosing your fish, read up on their preferred water conditions — or risk killing some of your fish slowly and painfully.

eXact Micro 7+ Water Testing Meter

No one in their right mind would argue that testing water for drinking, use in a pool, watering crops, etc. has to happen. One might, however, argue that using test strips and liquid test kits which require the user to match colors can lead to approximations and assumptions regarding critical water parameters such as pH, chlorine/bromine/sanitizer levels, alkalinity, total hardness, heavy metals, etc.

We all know what assumptions can lead to: Making an a## out of you and me.

No one wants to get sick from dirty or polluted water so when accuracy matters most, you may want to put down the test strips and liquid test kits and opt for a verstile water testing meter such as the eXact Micro 7+ which tests for NINE critical water parameters using direct read measurements and an additional TWENTY-SEVEN other important water parameters with the use of a conversion chart.
