Access to a clean, reliable water source is necessary to sustain population growth and promote economic development. Currently, about 3 billion people, approximately 1/2 of the world’s population, depend on groundwater supplies as their source of drinking water,...

Applications & Capabilities groundwater In order for the global community to maintain its population growth, we need sustainable management of our groundwater resources. YSI is committed to providing cost-effective monitoring and sampling solutions to help groundwater professionals meet this challenge. Our technologies offer real advantages that result in real savings. Whether you require a handheld instrument for spot sampling down well or in a ow cell, a level instrument for aquifer tests, or an instrument for long-term monitoring with optional real time data acquisition, partnering with YSI...

Level measurements provide the fundamental source of knowledge for highly dynamic groundwater systems. Hydrologic stresses on these systems affect recharge rates, specic capacity and transmissivity. Long-term water level measurements provide data to evaluate, develop, design, implement, and accurately monitor the effectiveness of groundwater use and management decisions. The human population currently withdraws approximately 1,000 km3 of groundwater annually.

Down-well sampling Parameters Dissolved Oxygen (polarographic, galvanic, optical), pH, ORP, conductivity, salinity, temperature, total dissolved solids, turbidity, ammonium, nitrate, chloride Single, dual and multiparameter handheld sampling Sampling Single Parameter Sampling Professional Plus* offers many measurement possibilities including single-parameter options for conductivity, salinity (60530), DO (60520), ISEs (60510) and temperature. Pro20 is a basic handheld for DO and temperature. ProODO® measures DO using optical technology. Pro Plus Dual Parameter Sampling Professional Plus* offers...

Quickly and conveniently capturing water quality data through spot sampling can provide immediate knowledge of the condition of local groundwater parameters. Long-term monitoring provides a broad understanding of monitoring well conditions during all phases of ground water uctuations. Plume delineation and pollutant transport are best understood through longterm data analysis. Comprehensive data on groundwater resources and pollution trends are not readily available at the global level. Monitoring Parameters Dissolved oxygen (polarographic, optical), pH, ORP, conductivity, salinity, temperature,...

collection of data must be truly representative of the site conditions. The use of low-ow purging and its methodology provides the least disturbance possible to meet this goal. The overall goal of any groundwater monitoring program is to collect unaltered water samples to provide the highest quality data possible. In order to achieve this objective, the The United States uses 83.2 billion gallons per day of fresh ground water from approximately 15.9 million water wells.
