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.
AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.

Wagtech water quality testing kits allow all levels of users to test for organisms, analyze key physical characteristics such as turbidity and conductivity, and measure specific chemical parameters such as pH, chlorine and ammonia, using simple, accurate procedures. Testing protocols conform to World Health Organization guidelines for assessment of potable water, and kits are chosen based on testing needs. All equipment is packed in IP67-rated carry cases with energy-efficient battery-operated instruments for use anywhere.
This multi-parameter test strip for drinking water tests free chlorine, total chlorine, pH, hardness, nitrate and nitrite with a single dip in less than 45 seconds. The strip, order code 2933-G, is appropriate for both municipal and well water applications. Each vial contains 25 test strips and is packaged in LaMotte’s exclusive flip-top vial with integrated desiccant liner and waterproof full-color chart on the label.
Isaac Plains is an open-cut coal mine in northern Queensland, Australia, that operates under an environmental authority. One of the environmental monitoring requirements that must be met is water monitoring. This includes monitoring potable water, mine-affected water, natural creek flows, water releases, groundwater and the receiving environment.
Onsite testing technology helps mine meet water monitoring requirements
The SenSafe Water Metals Check test is a quick, accurate, inexpensive way to determine toxic metal levels in tap water. This patented test strip develops red in the presence of toxic metals above 10 ppb in only two minutes. It detects toxic +2 valence metals found in tap water. Because of its detection sensitivity, it confirms the need for water filtration or remediation. The test can be purchased for $19.99 for 50 tests or $5.99 for six tests with instructions and a color chart.

The titration and ion chromatography system offers complete automation for testing properties and ions in drinking, ground, surface and wastewater. It minimizes operator time and simplifies sample analyses. The system combines the determination of up to 20 parameters from a single sample into an automated workflow. It determines conductivity, pH and alkalinity, and also can provide results for total hardness, ion balance and carbonate hardness.
