The Coliform/E. coli Indicator bacteria test kit (Code 4-3616-UV) includes five tubes, each with a nutrient tablet. The five tubes are each inoculated with 10 mL of sample water and incubated for 24 to 48 hours, depending on the ambient temperature. A change in the color due to acid production and the formation of gas bubbles in the reconstituted gel indicates the presence of coliforms.
Glyphosate is an herbicide that is regulated under the Safe Drinking Water Act. It is an ingredient in Roundup, a widely used herbicide, as well as more than 700 other products for sale in the United States.
The initiative is in response to an Aug. 5 mine waste spill into the Animas River
In response to the Aug. 5, 2015, spill of mine waste into the Animas River, the New Mexico Environment Department (NMED) and the U.S. Environmental Protection Agency (EPA) are partnering to test private domestic water supply wells located in the Animas River valley in New Mexico. Testing will identify metals that are of concern in relation to the spill, and other parameters that help in understanding the general quality of well water.
Monitoring water quality is essential for sustaining healthy ecosystems, ensuring public safety and managing water resources. Various characteristics such as pH, turbidity and dissolved oxygen can be measured to establish an overall profile of water quality and assess the viability of water for a particular use.
Processes & procedures for evaluating dissolved oxygen in water
The Smart Brew Kit and Smart Brew Advanced Kit are handheld smart photometer systems for measuring a craft brewer’s water quality. Using the eXact iDip Smart Photometer System, the kits integrate two-way wireless communication with a smartphone. The kits measure calcium and magnesium hardness, chloride, pH, sodium, sulfate, total alkalinity and total hardness. The Advanced Kit includes the VisionPlus digital pH meter.
This biopolymer test kit is designed to be used on site and provides real-time, accurate results in minutes. Every minute counts in sensitive storm water runoff situations, and waiting for results could lead to detrimental environmental impact at a job site. The new test kit is economical ($4 per test) and includes materials for up to 100 field tests.
This new family of portable meters is designed to measure pH, ORP, ion concentration with an ISE, conductivity and dissolved oxygen. The new meters—HI98190, HI98191, HI98192 and HI98193—feature a large backlit graphic LCD that is easily viewed under any lighting condition. An intuitive interface allows for a simplified user experience. All meters have dedicated keys for routine functions including calibration, setup, GLP and recall of logged data, which can be transferred to a PC with the built-in micro USB.
FCL Series sensors use amperometric measurement technology to provide accurate monitoring of free chlorine in process applications. The sensors are compliant with U.S. EPA method 334.0 for measuring drinking water. Models are available to cover 0- to 2-ppm, 0- to 5-ppm and 0- to 10-ppm ranges. The sensors’ membrane design features a mesh reinforcement clamp for stability and durability. The integral 4-20 mA isolated signal output is enhanced to eliminate ground loop errors, reduce noise and block high-voltage transient surges.
Water treatment can be a complex problem to solve, depending on which contaminants may be present and the desired water quality. There are a variety of contaminants that can make water unsafe to drink, such as microorganisms, inorganic metals and other inorganic compounds, organic chemicals and radiologicals. The presence of certain contaminants like calcium, magnesium and iron may not affect the safety of the water, but can make it unpleasant to drink and more difficult to clean with.
Water quality testing can be a critical part of a company’s process. Whether it is a screening method for different water quality parameters, part of a process that requires the addition or subtraction of chemicals, or even compliance monitoring for consumables and effluents, water quality testing is a major part of the quality control process.
