Saldanha in the Western Cape of South Africa is a small port town on the northern shore of Saldanha Bay. The bay is a naturally sheltered harbour, making it ideal for exporting iron ore on massive ships. It serves the region’s base metal mines and a heavy minerals smelter, and is also the location of… Continue Reading »
Download Technical Bulletin 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 »
Solinst Double Valve Pumps Download Technical Bulletin 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,… Continue Reading »
Low Flow Sampling Since 1996, low flow sampling has become an increasingly approved method for obtaining high quality groundwater samples. Through the work of Puls and Barcelona, the US EPA released standard operating procedures for low flow sampling (EPA/540/S-95/504). Following such guidelines ensures the collection of samples that are representative of actual in-situ conditions. Low… Continue Reading »
