Our solutions illustrated

Groundwater Sampling

Groundwater sampling methods are determined by borehole diameter, depth to water, required flow rate, sampling objectives and the parameters being analysed. Flux Enviro are proud to provide a comprehensive of sampling instruments for no-purge sampling, low-flow sampling, well purging and higher-volume groundwater abstraction.

For low-flow sampling, pumps can be combined with multiparameter instrumentation and flow cells enabling live monitoring of groundwater conditions and to demonstrate well stabilisation prior to sampling. YSI ProDSS, YSI ProQuatro and EXO sondes are available with flow cell arrangements.

Groundwater Quality Monitoring

High quality water quality instrumentation is core business at Flux Enviro. We supply an extensive range of instrumentation to assess water quality in the field and to supplement laboratory analysis. For periodic 'spot' measurements and low flow groundwater sampling consider the YSI ProQuatro and ProDSS instruments. For longer term deployments offering continuous monitoring consider the YSI EXO multiparameter sondes with the option of remote data to your mobile device or PC using our telemetry range.

Common field parameters for low-flow groundwater sampling include;

• pH

• Conductivity (derived; specific conductance, salinity, total dissolved solids (TDS), resistivity)

• Dissolved oxygen

• Oxygen redox potential (ORP)

• Temperature

• Turbidity (derived; total suspended solids)

• Others - ammonium, ammonia, nitrate, chloride

Groundwater Level Monitoring

Assessment of groundwater level is key for all hydrogeological studies. Our range includes solutions for manual water level measurements, continuous logging and remote data;

• Manual water level meters

• Pressure transducers and data loggers

• Vented and absolute pressure sensors

• Borehole and piezometer installations

• Remote groundwater telemetry

Installation and materials

To compliment our groundwater range, Flux Enviro offer installation materials including narrow diameter well screen, bentonite and well caps. Furthermore, our team offer comprehensive piezometer installation services for shallow installations using handheld window sampling and sacrificial cone methods. For large scale projects, larger diameter well screen or drilling works please reach out and we'll refer you to our recommended providers.

Conductivity Monitoring

Conductivity provides a useful and often underutilised indicator of changes in groundwater chemistry and flow. For example groundwater conductivity profiles with a borehole serve to inform groundwater ingress, flow rates and well construction. Similarly, in-situ conductivity measurement may be used to determine groundwater flow rate, hydraulic conductivity, resistivity via dilution or tracer tests.

We can provide equipment for:

• Conductivity, temperature and water level logging

• Conductivity profiling - CT2X or LTC meter

• Manual field measurements

• Remote conductivity monitoring

Pumping Tests & Aquifer Investigations

Monitor groundwater response during pumping, abstraction and aquifer investigations.

Equipment can include:

• Manual water level meters

• Pressure transducers and data loggers

• Flow measurement

• Barometric pressure loggers

• Conductivity and water quality instrumentation

Remote Monitoring

Assessing groundwater parameters via a single or periodic sampling campaign offers useful insight however to truly understand seasonal, climatic, operational or other relationships continuous datasets are necessary. Combining our extensive range of sensors with telemetry instrumentation offers groundwater data from the field directly to your mobile device offering;

• Enhanced data availability

• Improved data acquisition

• Automated alarms and notifications

• Multiparameter and multi location sensor networks

• Substantially reduced operational expenditure

See our 'Quarry and Mining' page for further information on remote data systems. Same solutions and approach can of course be applied to other groundwater and hydrogeological monitoring applications.
