When it comes to drinking water safety, many new innovations are focused on emerging contaminants. One new testing method, however, focuses on something that has plagued drinking water for ages — contamination by fecal matter. Water Quality Products Managing Editor Kate Cline recently spoke with Vladislav V. Yakovlev, developer of the technology, about the new testing method and its potential benefits.
Kate Cline: Briefly describe the new detection method procedure.
A new method for detecting fecal matter in water
With drinking water becoming scarcer due to drought in highly populated areas and drinking water sources becoming more polluted, both individual homeowners and businesses are becoming aware of the need for drinking water conservation. This brings to mind the old saying, “reduce, reuse, recycle.”
Integrating water conservation strategies into water management
S465 Series probes were designed as an alternative to Acu-Trol pH and ORP probes for swimming pool control, industrial, municipal and potable water applications. Constructed of polyphenylene sulfide, the probes offer improved chemical resistance. The sensor technology delivers accurate measurement over a range of 0 to 14 pH or -1,000 to 1,000 mV for ORP.
Legionella occurs naturally in the environment and is most commonly found in water. These bacteria thrive in warmer environments, so they are often found in hot tubs, hot water tanks, cooling towers, larger plumbing systems and decorative fountains.
Proper testing & maintenance help prevent deadly Legionella outbreaks
The eXact iDip handheld photometer uses the patented iDip4 reagent delivery method, a quick, safe and easy procedure for analysis. The methodology limits source of errors in results and provides smooth, precise reagent dispersion into samples without leaving suspended solids in the sample vial. The photometer provides wireless connectivity with Apple mobile devices. Data are transferred between the two devices when paired with the photometer using Bluetooth Smart wireless technology.
The Sievers M9 total organic carbon (TOC) analyzer measures TOC in a broad range of samples, from ultrapure water to process water. The analyzer can measure conductivity in grab sample or auto sampler modes, and produces TOC results in two minutes. The analyzer is offered in three versions—portable, online or laboratory—and is available worldwide, meeting all relevant global regulatory requirements.
The SAM-1 Smart Aqua Meter turns smartphones and tablets into pH, ORP or conductivity and temperature meters. Connect the meter and smart sensor into the audio jack of a smartphone or tablet and it is ready to take accurate readings. The sensor type and calibration data are auto-recognized. Easily record reading details such as time, date and GPS coordinates with location names and comments. Measure samples in the lab, field or plant, and share readings instantly via e-mail.
At only 18 sq in., the vario TOC Cube analyzer handles a wide range of samples, from ultrapure water to sludge. With large-diameter sample tubes — 0.8 mm — it easily handles somewhat turbid samples. The automatic liquid carousel can be swapped with a fully automatic solids carousel for samples with larger particles. An ash crucible protects the catalyst tube from plugging, allowing up to 3,000 samples to be analyzed without a reagent change.
The YSI Pro1030 handheld meter measures pH or ORP, plus temperature, conductivity, specific conductance, salinity and TDS. It has user-replaceable pH and ORP sensors, cables and a convenient calibration. Its ruggedness is backed up by military-spec connectors, IP67 waterproof and rubber over-molded case, and 1-meter drop tests. A four-electrode conductivity cell is built into the cable and requires minimal maintenance.
Before doing any testing, the best thing you can do is talk with your customer. Find out as much as you can about their water source, usage, aesthetic issues and family concerns. All of these factors will play into what you may test the water for in order to fully treat it. The source of the water will give you clues as to which contaminants may be present. For example, groundwater typically contains more minerals than surface water.
