Long-Term Monitoring & Resource Management

Long-Term Ground Water Monitoring Develop historical data on ground water aquiers to determine waterinuences and usages or residential planning, water rate billing, contamination plume direction, ground water/suracewater interaction, seasonal water demand, and other related issues. One or more monitoring wells are equipped with

vented water level instruments. Each well will typically be measured or base-line water levels and temperature. The mostcommon log type used is linear, typically at 15-minute intervals or longer.

Lake and Reservoir Monitoring Track water levels over extended periods o time to determine yearly demand andsupply. Water level instrumentation is normally placed in a slotted PVC pipe or stilling well and vented to atmosphere. Themost common log types used are linear and event.

Flood and Storm Surge Monitoring Gather data on ood events and their environmental impact. Instrumentsare placed in a stream, oodplain or area o interest and secured to prevent loss in a ood event. Absolute or non-vented

instrumentation is oten used due to concerns o ooding. Absolute pressure sensor data must be post corrected orbarometric changes or accurate level data. The most common log types used are linear and event.

Storm Water Monitoring Collect data on amount and rate o storm water runo to assess recharge rate into groundwater aquiers and to monitor the impact o ground water/surace water interaction. Vented or gauged instruments are

mounted in outall basins, storm sewers or ground water wells near recharge area. The most common log types used are

linear and event.

Estuary Level and Tide Monitoring Gather and report tidal changes and water level elevations in coastal areas.Instruments are mounted on fxed structures in PVC pipe or stilling wells and vented to atmosphere. The most common

log type used is linear average. For maximum accuracy, tide gauge systems should compensate or water density.Wetlands Monitoring Monitor long-term health and viability o coastal or inland marshes and wetlands. Vented ornon-vented instruments are placed in a slotted and screened PVC pipe. Absolute pressure sensor data must be post

corrected or barometric changes or accurate level data. The most common log types used are linear and event.

River and Stream Gauging Determine and track water level over extended periods o time and track impact odischarge, rainall and runo. The level instrumentation is usually placed in a slotted PVC pipe or stilling well with a vented

cable. The most common log types used are linear and event.

River Crest Stage Gauging Determine and track high water levels or ood crest o streams and rivers. Absoluteinstrumentation is secured to a fxed structure, such as a bridge piling. Absolute pressure sensor data must be postcorrected or barometric changes or accurate level data. The most common log types used are linear and event.

Aquier Characterization (Slug and Pumping Tests)

Slug Test Estimate hydraulic conductivity (K) in minutes as opposed to hours or a pump test. This methodrequires the depression or elevation o static water in a well, and the measurement o time it takes to

equilibrate. This is done by inserting a slug into the well causing the water level to rise or by removing a slugcausing the water level to all. Time is measured until the level returns to its original static position. The most

common log types used are logarithmic or ast linear.

Pumping Test (step) A well is pumped at dierent rates or short periods o time, and the aquiersresponse or drawdown is measured in a monitoring well to determine well efciency and fnal pump rate or aconstant rate pump test. The most common log types used are logarithmic in the pumping well and ast linea

in the monitoring well.

Pumping Test (constant rate) Also known as a yield test, a constant rate pump test is typicallyperormed ater a step test. Pump tests deliver a more accurate hydraulic conductivity value (K) compared

to slug tests. The pumping well is pumped at a constant rate or 24+ hours, and level data is collected inmonitoring wells to determine the storage coefcient (S), radius o inuence and other hydrologic parameters

The most common log types used are logarithmic or step linear.

Specialty Applications

Dewatering Monitor the removal o water when pumping a riverbed, constructionsite, mine, quarry or water well. Vented or non-vented instruments are placed in the

appropriate areas to monitor the water level. The most common log type usedis linear.

Dual-Phase Extraction Monitor ground water levels in a sealed well duringremediation o contaminated soil. The most common log type used is linear.

Landfll Monitoring Determine the highest measured ground water level andrainall/recharge relationships. Landfll design engineers and regulatory agencies

use this data to determine landfll expansion easibility and design requirements.

The most common log types used are linear and event.

Municipal and Process Monitoring Monitor water levels in an establishedwater system by attaching the logging instrument directly to a SCADA or PLCsystem. The most common log type used is linear. Level TROLL instruments

(300, 500, 700) eature Modbus (RS485), SDI-12 and 4-20mA outputs and canbe connected directly to a telemetry, SCADA or PLC system without any

special adaptors.

Gauged sensors eliminate the eect o varying atmospheric pressure on the

measurement and the need or post-logging data compensation. Gaugedsystems are the most accurate.

Absolute sensors will work or all applications, provided that a barometric record is

kept and data is post corrected.

All In-SituLevel TROLL instruments are calibrated over the ull pressure

and temperature range o the instrument. Many other loggers on the market arecalibrated at only 1 or 2 points.

LevelTROLLMeasurement Types

Absolute (Non-Vented) vs. Gauged (Vented)

Defnition and Background

Absolute(non-vented) sensors respond to atmospheric pressure and pressurehead o water above the sensor. Its measurements are read in psia (pounds

per square inch absolute) relative to zero pressure. PSIA sensorsmust be

compensated or atmospheric pressure using a Baro TROLL

.Gauged(vented) sensors allows atmospheric pressure to be applied to the back

o the pressure sensor, canceling out the eect o external atmospheric pressureuctuations. Measurements are in psig (pounds per square inch gauged) relative to

atmospheric pressure. PSIG sensorsmust be deployed on vented cable

with desiccant.

Accuracy Considerations: Total Cumulative Error

Logging TypesLinearMeasurements are logged at a fxed interval o 1 minute or more; commonly used in long-termmonitoring applications. (Log with any Level TROLL instrument.)

Linear AverageEach logged measurement is the average o several ast measurement; used orapplications such as tide gauging. (Level TROLL 700 only.)

Step LinearMeasurements are sampled and recorded on a user-defned schedule which may includemultiple steps, each with a unique linear measurement interval and duration; most commonly used inpumping yield tests or high-capacity wells where the pumping rate remains constant. (Level TROLL 700 only.)

EventOne parameter is checked or an event, and data is logged at a user-defned baseline rate in non-eventconditions and at an increased user-defned rate when the event is occurring; used to catch events that are notpredictable without logging unnecessary data, such as storm events. (Log with any Level TROLL instrument.)

True LogarithmicMeasurements are logged on a logarithmically decaying schedule and gradually geturther apart until they become linear; most commonly used in rapid drawdown pump, purging and slug tests.(Level TROLL 700 only.)

Fast LinearMeasurements are logged at a fxed interval o 1 minute or less. The linear sample interval is veryast and the duration o the log is short. Alternatively used in rapid drawdown pump, purging and slug tests. (Log

with any Level TROLL instrument.)

Sotware Utilities

In addition to depth and pressure, water level measurements can be expressed inseveral ways. In-Situ oers multiple choices when setting a water level reerence.

1. Depth to Water Records the distance rom the top o a well casing or otherreerence point down to the water surace. Logged readings increase as the waterlevel decreases (i.e., as the water surace gets arther away rom the reerencepoint). This reerence point measurement is commonly used to monitor drawdownin ground water wells.

2. Elevation Relates the sensor measurements to mean sea level (MSL) or anyother datum you choose. Logged readings increase as the water level increases.Elevation reerences are commonly used in surace water monitoring.

3. Gauge Height Reports water level readings relative to a sta gauge. Useulor river and stream gauging.
