The Analytical Side to Compliance with Drinking Water Regulations
Two new U.S. Federal regulations went into effect in 2009 that directly impact drinking water utilities that use chemical disinfection. Specifically, the Ground Water Rule (1) and the EPA Method 334.0 are now in place with the purpose of improving the quality of drinking water.
This paper summarizes the key elements of the new regulations and describes how they affect utilities’ daily operations, plus it will provide a comparison of available technologies for monitoring and calibration ... |

What You Don’t Know About Snow: The USDA’s SNOTEL Network is Playing a Critical Role in Protecting Water Resources in the Western United States
There are many complex political, social, environmental, and scientific challenges surrounding water resources in the western United States. Water is scarce and does not occur when and where people need it the most. According to the US Geological Survey (USGS), about 80 percent of fresh water used in the western United States is appropriated for irrigation. Over the past 150 years, society has diverted streams, built wells and created reservoirs to better distribute water to where it is needed the ... |

Ultrasonic Algae Control LG Sound
LG Sound, controlling algae in Irrigation reservoirs
Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown.
The LG Sonic® uses the newest ultrasound techniques to inhibit the growth of algae and prevent the growth of unwanted fungi in your water reservoirs. The LG Sonic® products are very easy to install. The transducer and float are being placed inside the water reservoir. The units can be turned on by connecting them to the power supply (electrical or solar).
