Rams Without Borders chose to use On-Target® Chlorine Tests for their philanthropic work in Las Cribas, El Salvador. The On-Target® tests were used to ensure the solar powered chlorination system the engineers had installed was working properly for the village. On-Target® tests are portable, fast, accurate, and easy-to-use making them the ideal tool for water testing. Our team would like to thank Rams Without Borders for the awesome work that they are doing!

Any true fan of Moscow Mules will argue that the drink needs to be served in a copper mug. But just how much of the copper from that special mug leaches into the drink? And how much copper is dangerous for a person to consume? The Access Sensor Technologies’ team did some digging, and this is what we found out.
First, why is the Moscow Mule drink served in a copper mug? We won’t go into detail here, but a good description of the history of the drink and why it is served in a copper mug can be found at this link, https://bit.ly/2PHn4q9.
Next, how much copper is safe for us to consume? Well, like for every chemical, the dose makes the poison. Copper is actually a necessary component for multiple enzymes in the human body. The Recommended Dietary Allowance (RDA) for adults is around 1.0 – 1.5 mg per day https://bit.ly/2ziNxjy, and is less for infants. The EPA has an action level for drinking water at 1.3 mg/L, also reported as 1.3 parts-per-million, or ppm for short https://bit.ly/2udAnml.
So are Moscow Mules unhealthy from a dissolved copper standpoint? The answer depends on who you ask. There have been recent news articles claiming that Moscow Mules could contain toxic levels of copper https://wapo.st/2TuiXvJ, and news articles that report claims of Moscow Mules being dangerous are just “chemophobic fear-mongering” https://bit.ly/2A8ClW9. It is true that acidic beverages in contact with solid metallic copper do start to dissolve the metal into solution, and it is true that the components of a Moscow Mule would make the drink acidic, so being inquisitive chemists, we had to investigate!
Our sample was the residual fluid (~1 mL) in a Moscow Mule mug that had been sitting in the mug overnight for approximately 9 hours. The sample had a pH of 5 – 6 due to the acidic ingredients that go into making a Moscow Mule. We added 150 µL of the sample fluid to an On-Target® copper testing card. The results were… 55 ppm copper!
What are the conclusions? A drink containing 55 ppm of copper would be dangerous to drink in large quantities, however, the initial sample volume was only ~1 mL which would equate to a total of ~0.05 mg of copper which is still well below the RDA value for copper. Moscow Mules are an acidic drink that will begin to dissolve copper into solution if contained in a copper mug. The results of our On-Target® copper test confirmed this, but does this make Moscow Mules unsafe to drink? Our answer is probably not. Unless you have a sensitivity to copper, or are an infant, you can probably continue to enjoy Moscow Mules in moderation. We do however strongly recommend not storing food or drinks in copper containers over long periods of time, as the dissolved copper concentration would likely continue to increase. Remember, our sample was taken after the remainder of the drink had been sitting at room temperature over many hours. The concentration of dissolved copper in a freshly made Moscow Mule is likely much lower, although we are looking for volunteers who are fans of the drink to test this for us! Thanks to one our biggest fans for submitting the Moscow Mule sample and thank you for reading!
Facts about Cadmium:
1) Cadmium is naturally occurring and can be found in small quantities in the Earth’s crust.
2) The most common uses for cadmium include batteries and electroplating, but cadmium is also used in some solar panels, televisions, pigments, and nuclear reactors.
3) Cadmium is highly toxic to humans and animals.

The future of air sampling networks
Access Sensor Technologies (AST) worked with the National Oceanic and Atmospheric Administration (NOAA) to deploy a network of Air Sampling Stations in Fort Collins, CO. The goal of this project was to address existing challenges with low-cost (<$200) aerosol sensors that operate on the principle of light-scattering nephelometry. These low-cost sensors, which have become widespread over the past decade, need a reference monitor because the data quality provided by these sensors is often unknown and time-variant. Current reference monitors, known as Federal Equivalence Monitors (FEM), are bulky and expensive. The goal is be able to use our less expensive and portable Ultrasonic Personal Air Sampler (UPAS) as a reference monitor in low cost sensor networks. To test our UPAS against the gold standard FEMs, we designed and built self-powered outdoor aerosol sampling boxes that integrate our UPAS with low-cost light scattering devices. We deployed an array of these boxes throughout Fort Collins, and several of the boxes were installed next to FEMs. Throughout the six-week deployment we collected over 500 filter samples and logged nearly 15,000 hours of light scattering aerosol data. Following data analysis, we will know if the UPAS can be used as a versatile, less expensive, calibration tool within a low-cost sensor network. Thanks to NOAA, Colorado State University, and the City of Fort Collins for helping with this project!
tap water testing
Old house? New house? The concentration of metals and other contaminants present in your home’s plumbing can change over time. Just because a house is brand new doesn’t necessarily mean the water coming from the tap is safer. Often new houses with copper plumbing can have higher concentrations of dissolved copper in the tap water since it takes time for a protective coating to form on the inside of new pipes. Older houses can also have metals from various sources present in the tap water as the plumbing begins to degrade over long periods of time. Tap water collected from an old house in Loveland, Colorado be seen in the bottle to the left. This water was collected from a rarely used basement tap in a house that is sixty years old. The water has a brown tint because it had been sitting in pipe for an extended period. Access Sensor Technologies’ On-Target® Water Testing Kits revealed that this discolored tap water had concentrations of 1 ppm copper and almost 10 ppm zinc. This test is a good reminder to test your tap water for metals if it is discolored or has an off-taste. Thanks to Julie and David for sharing their On-Target® water testing results!

On-Target water testing in Peru
This summer, Hana O-Hagan, a student at Creighton University, traveled to Villa El Salvador, Peruto test water quality at various locations in the community. Access Sensor Technologiesdonated On-Target® Water Testing Kitsto Creighton so that Hana would have a portable, easy-to-use test she could use at the sampling location. Hana used On-Target® Water Testing Kitsto analyze water that was used for cooking, drinking, and cleaning at 23 locations in the village. Hana was investigating to see if any of these water sources were contaminated with toxic metals. Back in the United States, Hana will use atomic absorption spectroscopy on the same water samples to see how laboratory data compares to the On-Target® results from the sampling locations. Our team at Access Sensor Technologies would like to offer a huge thanks to Hana, Dr. Erin Gross, and Creighton University for the amazing work they do in Peru, and for allowing us to be involved with such a great project! We will provide an update on the exciting work that Hana is finishing up soon! Some images from Hana’s trip can be seen below.
Access Sensor Technologies is working with the National Oceanic and Atmospheric Administration (NOAA) to deploy a network of Air Sampling Stations in Fort Collins, CO. Through this project, we aim to test and validate a calibration solution for low cost light scattering sensors that have been making way into aerosols research and citizen science.
Happy Halloween from the Team at Access Sensor Technologies! Let us brew up something magical to simplify your sampling! Contact us today to learn how we can help make your sampling needs less spooky!
