A Growing Focus on Groundwater

In recent days, groundwater has been gaining attention. Increased hydraulic fracturing operations have caused controversy over potential methane gas contamination. Reports indicate that groundwater aquifers, especially in the drought-prone southwestern U.S., are being depleted more quickly than they can be recharged. Surveys, like the one recently released by the U.S. Geological Survey (USGS), reveal that contaminants such as arsenic are widespread in the nation’s water wells.

Better Quality Assurance Through ORP

There are many forces driving water treatment and quality assurance practices: efficacy, reliability, health and safety, cost, practicability, aesthetics and government regulations from government agencies such as the U.S. Environmental Protection Agency. Though effective, there are alternatives to the traditional testing methods prescribed for characterizing and monitoring water quality, saving time and money.

Emergency Preparedness

As I write this, the U.S. is in the wake of two natural disasters: the earthquake that rocked the East Coast on Aug. 23 and Hurricane Irene, which spun its way from the Carolinas to Canada just a few days later.

ITS introduces the eXact Chlorine Plus, a handheld photometer that offers faster, safer, easier and more precise water testing. The meter is ideal for oxidizer testing and provides direct read capabilities for combined chlorine, free chlorine, total chlorine, hydrogen peroxide low range, high-range free chlorine and glycine. Percent transmission allows for testing of additional parameters.

Arsenic & Activated Carbon

In 1986, California voters approved an initiative to address growing concerns about exposure to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known Proposition (Prop) 65. The act requires the state to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 800 chemicals since it was first published in 1987.

A New Choice in Beverage Testing

The beverage industry’s traditional water testing methods are effective for scientific and safety purposes but can be time and labor intensive as well. Most labs testing bottled water or process water have relied on agar-based methods for decades. Recently, a more efficient method was found with the “go-to” bacteria-testing application, which food-processing companies have relied on for the last quarter-century.

The Ultrameter III 9P titration kit features fast, one-touch measurements for conductivity, resistivity, TDS, ORP, free chlorine, pH and temperature and in-cell alkalinity, hardness and LSI titrations. Alkalinity, hardness, pH and temperature values can be manipulated in the LSI calculator to predict the effect of changes on water balance.

Water Quality: A Selling Point

Private wells are largely unregulated, and the task of ensuring safety is usually left up to the homeowner. A handful of states have regulations requiring a water test on a private well when the property is sold or a new well is drilled. While not every state has regulations, there may be testing requirements at the county or township level for real estate transactions or certificates of occupancy.
