Our ongoing series Life of a Sample explores what happens behind the scenes at WETLAB. If you missed part one, check it out here!
The next step for a sample at WETLAB is sample preparation. This process takes one day, and involves several different processes and people. During the first step, all samples undergo the same log-in and review procedure, and sample prep is where the tests begin to diverge dependent on which analyses are required. Some samples, including many soil tests, require the compositing of several different samples into one representative batch. For many tests, different filtered and unfiltered aliquots are needed; these pieces are split up into different bottles and preserved as needed. Once properly split, the samples are released to the lab.
Before the samples reach the lab, laboratory scientists clean and prep the necessary equipment, and lab technicians prepare batches of samples based on the tests logged in during step one. Some tests are ready to preform immediately, and those move on to step three. For others, extractions are needed. This includes TCLP (toxic characteristic leaching procedure), cyanide extraction, MWMP (meteoric water mobility procedure), and humidity cells. Some of these extractions take more than one day, like humidity cells, which can continue for a few months up to several years. Ensuring proper preparations are preformed allows the rest of the analysis to run smoothly. After the filtering and extractions are completed, it’s time for step three: distillation and digestion.
The EPA revised the Total Coliform Rule (TCR) in 2013, but these changes need to be implemented soon. By April 1, 2016, all compliant public water systems will have to implement the revised TCR requirements. At WETLAB, we take a great interest in the new regulatory measures that affect our clients, and we decided to take a closer look at what the Revised Total Coliform Rule entails.
According to the EPA, the RTCR is intended to “protect public health by ensuring the integrity of the drinking water distribution system and monitoring for the presence of microbial contamination.” Which essentially means that the RTCR confirms what the TCR has already established since 1989, and then expands upon the initial rule. The RTCR requires that all public water systems (PWS) show that they meet the legal limit for E. coli through expanded required monitoring. The rule also goes on to specify what the actual frequency and timing of the required microbial testing is; which is based on the populations served by the PWS, the type of PWS, and what type of source water the PWS uses.
To find the exact requirements of the new rule, we highly suggest visiting the EPA’s page on the RTCR here. These changes do not have to be implemented until April 1, 2016, but it is crucial to have an accurate understanding of the new rule.
At WETLAB, we strive to provide our clients with the most accurate and up-to-date information available. If you have any questions, about this rule or any other, please call us at (775) 355-0202.
Effluent water could soon become part of your normal drinking water in Northern Nevada. According to KTVN, reclaimed water is around 30% cheaper than potable water, but the problem is that waste water is not drinkable yet. Yet is the key word here, because regulations that define how much the water will need to be treated are working their way through the Nevada state legislature, and lawmakers are hoping to see them adopted by the 2017 session.
As everyone knows, Northern Nevada is suffering a severe drought. Having another way to reuse water will have a great, positive environmental impact on our already low waterways. Effluent water is already being used in some ways, mostly to irrigate parks and golf courses, but more could be put back into eventual use by the proposed measure. The process involves injecting semi-treated water directly into the ground, so that it will later make its way back into our pipes. This will ease the strain that is currently put on the Truckee River, which will in turn help with our ecosystem.
Effluent water is defined as waste-water, whether treated or not, that flows out from an industrial treatment plant or sewer. Secondary effluent is that same water that has been treated, but not to the point of purity. Obviously, the main difference between potable and effluent water is the cleanliness of the water, and its fitness for human consumption.
WETLAB preforms several tests on effluent water for many different clients, including public and private companies. Some of these tests are Biochemical Oxygen Demand (BOD), which tests how much oxygen demand the effluent water has, and Total Suspended Solids (TSS), which tests the amount of suspended solids within an aqueous sample. Several other tests are often performed in tandem on effluent water samples, including Total Nitrogen, Nitrate + Nitrite, Ammonia, Total Phosphorous, and Fecal Coliform. These tests all provide a detailed profile of what exactly is contained in an effluent sample, and allow proprietors to know how to best treat their water.
Singapore and Texas have already implemented effluent-to-drinking-water purification systems, with positive results. To read more about this program in Nevada, and to see an interesting news report on it, click here.
The Environmental Protection Agency (EPA), in conjunction with the U.S. Army Corps of Engineers, recently finalized the Clean Water Rule. This rule is aimed at protecting our nation’s water resources from pollution and human ruin, especially the smaller streams and wetlands.
This rule is an attempt to make a difference in larger waterways by cleaning the smaller upstream streams and wetlands that feed them.
There is no expanded authority with the instatement of the Clean Water Rule, because the EPA already has the authority to impose these regulations based on the authority granted in the Clean Water Act.
Some farmers and property owners have expressed concern about regulations regarding smaller streams, but environmental groups laud the new rule as long overdue.
WETLAB continues to test water for EPA compliance. See how we can help you comply with the new regulations by calling us at (775) 355-0202, or emailing us at info@wetlaboratory.com

The Environmental Protection Agency (EPA) awarded $15 million to the State of Nevada this month, aimed at improving pollution control and drinking water infrastructure, things we think are of the utmost importance here at Wetlab.
The funding goes to the Nevada Division of Environmental Protection (NDEP), broken down into a $6.5 million grant for the Clean Water State Revolving Fund, according to an article found on waterworld.com, and $8.5 million for the Drinking Water State Revolving Fund.
The grants are just the latest in more than $320 million in EPA funding awarded over the last 24 years, according to Jared Blumenfeld, the EPA’s regional administrator.
“Without this investment and creative financing at the federal level, many communities would not be able to provide for Nevadans’ basic needs for clean, safe drinking water and proper wastewater treatment,” Blumenfeld said.
In the past, according to the article, EPA money has funded new well construction aimed at decreasing arsenic levels in Tonopah, as well as advanced wastewater treatment in Clark County to reduce bacteria and chemicals making their way into Lake Mead.
Other water quality projects from the NDEP have ranged from non-point source pollution control, watershed protection and restoration, water efficiency improvements, wastewater reclamation, and other wastewater treatment projects on the Clean Water State SRF side, as well as drinking water infrastructure on the Drinking Water SRF side.
Water Supply News
On the supply side of our state’s water news, southern Nevada looks like it’s going to get some reprieve from dry conditions thanks to a wet fall on the Rocky Mountains’ west slope, according to mynews3.com.
The Colorado River Commission reported rainfall in some areas of up to 50 percent above normal for the month of September, which will help the more-than-half-empty Lake Mead, the primary water supply for Las Vegas.
Lake Mead is at 1,104 feet, anything below 1,075 is considered a shortage.
First Lady Michelle Obama has been advocating for people to drink more water in an effort to improve health.
If you’re a fan of WETLAB on Facebook, you’ll know that’s something we whole-heartedly agree with.
According to an Associated Press report, Obama launched the campaign earlier this month in Watertown, Wisc., saying drinking more water is the “single best thing Americans could do to improve their health.”
“Water is so basic, and because it is so plentiful, sometimes we just forget about it amid all the ads we watch on television and all the messages we receive every day about what to eat and drink,” she said in the article.
Mrs. Obama spoke about seeing improvements in her two daughters’ health after deciding to drink more water, but was careful not to attack the soft drink industry, according to the article, because she said healthy changes won’t happen without buy-in from the food industry.
In fact, this campaign is backed by the American Beverage Association, which represents makers of soda, sports drinks and energy drinks, according to the article, but many of those companies also make bottled water.
This is where some environmental groups take issue.
“We applaud the first lady’s initiative to encourage people to choose water over sugary beverages, but we do have concerns that this partnership is working in conjunction with the bottled water industry and with that instead she were encouraging people to choose the much more affordable, more regulated option of tap water,” said Emily Wurth, water program director for Food and Water Watch in the article.
The issues are two-fold: the waste created by disposable water bottles (about ¼ of plastic water bottles are recycled according to Wurth) and tap water is held to higher quality standards than bottled water, which often comes from municipal water systems anyway, making the premium price questionable, according to the article.
Local Water News
In northern Nevada Water news, winter forecasts are starting to turn up, offering interesting predictions into Sierra snow pack and our subsequent water supply. The Farmers’ Almanac is calling for a cool winter with near-normal precipitation, which would be an improvement over the last two years. But the National Climate Prediction Center is having a tough-time nailing down a prediction, reporting “equal chance of being below normal or above normal for snowfall for the western states.” Only time will tell, but we’re keeping our fingers crossed.
In this blog, we spend much of our time talking about water quality testing news, science and politics that we find interesting; but with this month’s blog, we decided to do something a little different.
Here at WETLAB we care about maintaining and improving water quality, above and beyond our roll in monitoring it. When we came across some tips for average citizens to help from www.cleanwateraction.org, we thought it was a great fit.
First is some news that’s been getting quite a bit of attention in the last few years: Don’t flush medicines, pharmaceuticals or personal care products down the toilet or down the drain. That includes anything from over-the-counter drugs to cosmetics and even sun screen or vitamins. They can all impact both the environment and our drinking water down the road.

Don’t use antibacterial soaps when you don’t need to. These products often contain chemicals that harm aquatic life, and can lead to antibiotic resistant germs.
Don’t put motor oil, detergents, fertilizers, pesticides or anything but water down storm drains. And speaking of motor oil, fix any drips or leaks on your car or truck so it doesn’t wash into the water supply with the rain.
Try to use natural gardening products over pesticides or chemical fertilizers. The same goes for inside the home–stay away from toxic household products in cleaning and home care.
Pick up after your pets! Their waste contains bacteria that can end up in the water supply when it’s washed down the storm drain.
Pave less of your property. The more water runs across pavement instead of seeping down into the soil, the greater chance it has to pick up pollutants, pick up speed and cause flooding or erosion.
These are just a few tips we thought were worth sharing. Please add your ideas by commenting on this post or on our Facebook page.
For most people, a drink of water is like eating or sleeping. It’s just something we do to stay alive.
The Western Environmental Testing Laboratory’s work is one of the reasons people rarely think about the water they drink. The Sparks-based lab handles wastewater and drinking water testing for private companies, research firms and municipalities to ensure its safety.
The company in December opened a Las Vegas branch at 3230 Polaris Ave., to better accommodate its 10 local clients. Utility Services owner Hollie Daines is a recent addition to WETLab’s client roster. Her company is distribution operator for 45 local small public water systems, ranging from homeowners associations to resorts. WETLab analyzes the water samples Utility Services collects from the systems each month.

WETLAB – Western Environmental Testing Laboratory takes a closer look at Water Quality Around The World.
We spend a lot of time looking into water quality here in Northern Nevada. A lot of time. So when we came across a Gallup poll on water quality around the world, we took a step back, to take a broader look.
Gallup surveyed residents in 145 countries around the world, asking, “In the city or area where you live, are you satisfied or dissatisfied with the quality of water?”
The highest satisfaction levels, measured by percent satisfied, were not surprisingly in the United States, Canada, western and northern Europe, according to the poll.
While the USA had 87 percent of respondents say they were satisfied – the same as Canada and Ireland – Both the United Kingdom and the Netherlands ranked higher at 91 and 92 percent respectively. Denmark, Norway and Sweden all took the top mark at 94 percent.
The other end of the spectrum, also not surprisingly unfortunately, where sub-Saharan African countries. At the bottom of the survey results was Chad, with only 21 percent of respondents were satisfied with water quality. Also on the low end were Nigeria and Ethiopia, both at 29 percent, Liberia, at 30 percent and Tanzania, at 35 percent.
It wasn’t all bad in sub-Saharan Africa – with Malawi, South Africa and Namibia at 79, 81 and 82 percent respectively.
Former Soviet Bloc countries also showed strong dissatisfaction, with Ukraine at 26 percent, Russia at 30 percent and Kazakhstan at 49 percent.
The rest of Asia runs from a low of 35 percent in Lebanon and 43 percent in Cambodia to 98 percent in Singapore. In the world’s largest population centers, China and India, satisfaction rated 75 percent and 68 percent respectively.
In the western hemisphere, Latin America and the Caribbean ranged widely Gallup said this water-rich area was prone to exploitation and contamination.
In the Caribbean, Haiti was at 44 percent, and the polling was done before the devastating earthquake of 2010. But nearby Jamaica responded much more positively, at 89 percent.
Guyana, a small country on the northern edge of South America, responded at 54 percent satisfied, while Uruguay to the south ranked at 91 percent. Mexico fell somewhere in the middle at 70 percent.
