5 Key Features to Look for in a Multiparameter Sonde

Before multiparameter sondes, water monitoring professionals carried a number of single sensor meters, colorimeter kits and a secchi disk to the field.  Water quality data was manually gathered, archived and managed. Sondes have became a preferred technique; both for spot-checking, profile applications and unattended continuous recorders. Until recently, the thrust of sonde innovation centered on…

Solar Power for Flow Monitoring without AC. No Power No Problem.

Solar power arrangements for flow monitoring systems can be an effective remedy for remote locations where power is often unavailable, or too time consuming / expensive to run. Several models of flow meters, auto samplers and water quality analyzers come in models that can operate on 12 or 24 VDC. A solar power system mainly…

Water Quality Monitoring With Remote Data Access

The need for remote data access for water quality monitoring stations is on the rise. Not only is there a significant cost involved in sending personnel into the field but there are also safety concerns in working in, over, and near the water. In addition, staff shortages can result in “stretching” out the time between…

Real-Time Monitoring of Water and DNAPL Levels Using Level TROLL 500 Instruments

In-Situ, Inc. Technical Note October 2011 A dense non-aqueous phase liquid, or DNAPL, is a substance that is denser than water and only slightly soluble. Because of these properties, DNAPLs introduced into the environment generally sink below the water table and may migrate down through an aquifer. This can pose risks to the environment and…

Real Time Water Quality Monitoring on Rivers

Long term water quality monitoring on rivers can be an arduous chore; and very expensive.  The cost of sending teammates into the field continues to skyrocket, especially when it is over water; not to mention the inherent safety concerns. All this for what amounts to a ‘snap-shot’ of water quality at the time of measurement…
