Approximately 30 million Americans get their drinking water from private household wells. Protection of private wells does not fall under the U.S. Environmental Protection Agency’s (EPA) Safe Drinking Water Act, so well owners must take it upon themselves to ensure their water quality. To keep water clean and pure and the well operating at peak performance, regular water testing is an important maintenance tool.
Selecting the right combination of tests for water wells
The TRM-1 is a wide-range TDS monitor, able to measure 0 to 10,000 ppm with three different sensors. It is ideal for water filtration/purification systems that require three sensing points, such as RO/DI systems. Each sensor is ¼ in. in diameter. The monitor comes with three ¼-in. quick-connect T-fittings. It is battery powered, has automatic shutoff, automatic temperature compensation and an accuracy of ±2% (of the reading).
Analytical Measurements manufactures probes for use with pH and ORP instrumentation, as well as resistance temperature detectors for use with automatic temperature compensating controllers/recorders. All probes work with many instrument manufacturers, as long as a BNC-type connection is used. The company offers standard industrial probes, as well as higher temperature/pressure, flat surface, spear type and cyanide probes.
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 SA1100 scanning analyzer provides portable drinking water testing for lead and copper. The lightweight, waterproof analyzer is capable of field or laboratory analysis. Tests are conducted with disposable sensors, with results in less than three minutes. Up to 500 results can be stored with time and date information. Data can be downloaded to PC or tablet devices for logging and tracking. Tests are guided with onscreen prompts on the LCD monitor.
The Prizma water analyzer and controller features automatic calibration and provides real-time online reports. The system is suited for use in private swimming pools and spas, ensuring sanitation and clear water. It works by applying electro-optic capabilities to accurately analyze test pads that automatically monitor water quality at regular intervals. A continuous indicator strip is run across a series of individual test sections, each providing analysis for a different chemical.
The field-ready DR 900 handheld colorimeter allows quick and easy access to testing methods. It can test 90 of the most commonly tested water parameters. Ruggedly constructed, waterproof, dustproof, drop tested and shock resistant, it is reliable even in harsh and challenging field conditions. The instrument has a backlit display option for use in low-light areas with the push of a button. It can store data from up to 500 tests, and comes with a USB port for easy data transfer.
Analytical Measurements offers buffers for calibrating analytical pH and ORP instruments in solution or powder form. Solutions for pH are available in pints (500 mL) for pH 3 to 12 or powder salts sold in packets. Solutions for ORP are available in pint bottles for 200 and 600 mV.
The MultiLab IDS line of laboratory instruments and smart sensors includes one-, two- and three-channel instruments that each measure up to three para-meters at a time, as well as smart digital probes for optical-based BOD5, pH, ORP and conductivity measurement. The line has easy-to-use and -calibrate menu-driven operation and improved data integrity and security.
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.
