Changes in legislation, combined with improved and lower cost sampling instrumentation, have encouraged consultants, researchers, and government agencies to obtain higher quality groundwater samples. No-purge, also known as passive or grab sampling, is one method that is gaining acceptance by many regulatory agencies for obtaining representative groundwater samples. The ITRC (Interstate Technology… Continue Reading »
Estimating aquifer properties, such as hydraulic conductivity (K) and permeability is an essential part of site characterization and creating accurate conceptual site models during site investigations. The data gained through aquifer characterizations help to plan further monitoring programs and remediation efforts. Packer Tests are a great way to obtain these aquifer characteristics… Continue Reading »
The Canadian Rocky Mountain Parks are designated as UNESCO World Heritage Sites for their “exceptional natural beauty”. The seven parks – Banff, Jasper, Kootenay, Yoho, Mount Robson, Mount Assiniboine, and Hamber – are known for their scenic mountain peaks, meadows, canyons, caves, hot springs, and glaciers. Their pristine alpine lakes also draw millions of visitors to the parks each year. But as we hear so often… Continue Reading »
It is widely understood that to properly and sustainably manage the world’s groundwater resources, collecting data on its quantity and quality is essential. Efficient, cost-effective options for accessing, storing, and sharing the data are needed to balance out the increased demand. Telemetry is one data retrieval method that is used extensively in environmental applications… Continue Reading »
Just 200 km north of Cape Town, South Africa, you’ll find a unique area that boasts a wide range of landscapes – from rugged mountains to lush river valleys. Groundwater feeds this region. Recently, demand on the high-quality resource has increased. There are over 50 relatively high-yielding groundwater abstraction wells used by the rural community. Continue Reading »
Over 90 per cent of historical coastal wetlands in South Central California have been lost due to development. One such area is the former upper arms of the Devereux Slough, located just northwest of the University of California, Santa Barbara (UCSB) main campus. In the 1960s, the wetland was filled to create a golf course… Continue Reading »
Double Valve Pumps can provide high quality, representative groundwater samples. However, to get the best quality samples from your pump, it is critical to understand how the Double Valve Pump works and how to operate it properly. Double Valve Pump Operating Principles: When a Double Valve Pump is submerged, hydrostatic pressure… Continue Reading »
Lithuanian speleologists (cavers) are using Solinst Leveloggers to collect water level data from some of the deepest caves on Earth! Between 2008 and 2012, cavers completed four expeditions to the Krubera Cave—the world’s deepest. During an expedition in 2008, two Leveloggers were deployed more than 1700 metres… Continue Reading »
According to the Canadian Disaster Database, “disaster floods” are occurring more often, and in general, the US National Climate Assessment reports that heavy rainfall events are on the rise worldwide. With flood events and destructive downpours intensifying—much of which can be attributed to climate change—the need for more detailed flood data is growing. More accurate… Continue Reading »
When used together, the Solinst 3001 Levelogger and 101D Water Level DrawDown Meter provide a solution for measuring drawdown accurately. Continue Reading »
