Solinst 401 Waterloo

Applications

Obtain groundwater samples, hydraulic head measurements and permeability measurements from many discretely isolated zones in a single borehole

In a Waterloo System the casing is sealed off at multiple levels using packers and a base plug. This creates a string of different screening intervals with fixed ports at precise monitoring zones which allow water in at that point but no where else along the length of well casing. A tube is attached to each port which individually connects that zone to the surface. The tubing acts as a miniature well (piezometer) into which the formation water enters via the port and equilibrates at its static level. With this system, at any given time at the surface manifold, one can have access to as many as 24 zones down the monitoring well.

Solinst 403 CMT

Applications

Identify vertical as well as horizontal contaminant distribution with transect monitoring

This multilevel system is reliable, easy to install and inexpensive. The CMT Multilevel System makes the accurate monitoring of contaminant plumes much more affordable. It provides detailed vertical as well as horizontal data. Monitoring zones are set where needed and the single tube design allows reliable seals between zones. It provides site assessors with a better understanding of three-dimensional groundwater flow and the distribution of contaminants in the subsurface. Remediation strategies can then be targeted more precisely, focusing efforts in the most effective manner. Two systems are available. The 1.7” (43 mm) OD polyethylene tubing, segmented into seven channels, allows groundwater monitoring at up to 7 depth-discrete zones. The 3-Channel System uses the same material and construction, but it is only 1.1” (28 mm) in diameter. This narrow tube was developed for smaller diameter installations, especially direct push where the annulus for seal placement is narrow.

Datasheet

Solinst 404 WaTerra Pump

The WaTerra Pump an inertial pump consisting of a riser tube with a one-way valve at the foot and a surface pumping mechanism. The valve allows water to enter the tubing as it is pushed downwards, and retains the water when the tube is pulled upwards again. The inertia of the water itself provides the force to carry it up to the surface whenever the tube is being pumped up and down. The water travels in a continuous column, with little disturbance, thus retaining volatiles. The pump can be combined with the WaTerra Hydrolift II or WaTerra PowerPack PP1 for mechanical operation.

Datasheet

Solinst 407 Bladder Pump

The Integra Bladder Pump is a bottom filling bladder pump suitable for both low-flow and regular-flow sampling. Two lines are attached to the top of the pump, one for “air in”, and another for “sample out”. In its relaxed state, water enters the pump from the bottom through the intake filter and fills the bladder inside. In its drive state, compressed gas flows into the pumps and applies pressure laterally to the bladder causing it to depress. A check-ball valve at the bottom closes forcing the water up the pump and out the “sample out” line and the cycle starts again.

The bladder ensures there is no contact between the air and the sample and is available in disposable LDPE or reusable PTFE. The Integra can lift from 150 m and is available in 25 m and 42 mm diameter stainless steel, or 42 mm diameter PVC. It is also easily convertible to a Double Valve Pump

Datasheet

Solinst 408 Double Valve Pump

The Double Valve Pump (DVP) is a pneumatic pump suitable for low-flow sampling, non-vertical applications and leachate/product pumping. Unlike a bladder pump where the water fills the pump and is then pushed out, in the DVP the system is “open” so the water rises through the pump and up the sample and air lines until it equilibrates at the static level. Compressed gas is pushed down the “air in” line which forces the water back down that line closing a check-ball valve at the bottom of the pump and up the “sample out” line. When the pressure is released, the water refills the pump and the “air in” line, while an upper check-ball valve prevents water in the “sample out” line falling back down. The DVP can be operated such that with a short enough drive time and a low enough applied pressure, compressed gas will never enter the pump body and thus high quality samples for VOC analysis can be taken.

Datasheet

Solinst 410 Peristaltic Pump

The peristaltic pump is a reversible pump that can be used for vacuum pumping or for delivering liquids or gases. Silicone tubing runs through the U-shaped pump mechanism where it is clenched shut at 2 points by plastic rollers holding a volume of air between them. The rollers push the air in the direction dictated by the controller creating a negative pressure behind them and a positive pressure in front. By the time the 2^nd roller has lost contact with the tubing, the 1^st roller has already clenched the tubing off at the start of the next cycle creating a greater negative pressure on one side and greater positive pressure on the other.

As a vacuum pump, the lift is dictated by the surrounding air pressure. At sea level it can lift approximately 10 m, the lift decreases proportionally to height above sea level.

Datasheet

Solinst 425 Discrete Interval Sampler

Applications

Sampling from below LNAPL layers and Sampling of LNAPL and DNAPL

Interval sampling in lakes, rivers and wells

Sampling at points of inflow to a well

The Discrete Interval Sampler is a stainless steel chamber attached to a reel via a length of LDPE tubing. The reel has a pressure attachment for pressurising and venting the chamber. Pressure is applied using a high-pressure hand pump.

The chamber is pressurised initially which forces a check-ball valve at the bottom downwards, preventing water from entering. When the sampler is at the desired depth, the attachment on the reel can be switched to the vent the internal pressure allowing the chamber to be filled by the hydrostatic pressure around it. At the top of the chamber there is a polypropylene check-ball that floats and closes the valve when water fills the chamber preventing sample from coming in contact with the tubing. This provides a high quality VOC sample as organic compounds will not be lost via adsorption onto the LDPE tubing.

Datasheet

Solinst 429 Point Source Bailer

Point source sampling can be used to profile an open borehole or screened well, to collect samples from distinct levels or points of inflow. There is negligible disturbance as can be caused by pumping and purging. Mixing of the sample with water from different levels in the well is minimized. Purging and disposal of purged water can be avoided, because sampling directly from a specific depth collects the water that has just flowed into the well at that depth.

Datasheet

Solinst 601 PVC Standpipe Piezometer

Applications

Water level monitoring, Permeability measurements

Slope stability investigations

The Solinst Model 601 Standpipe Piezometer is designed to be placed within a drilled hole to provide a filtered inlet point. The pointed PVC tip is also suitable for pushing into very loose sands at the base of a borehole, a stream, or into very loose tailings pond sediments. The 601 is excellent for metals sampling, as it is composed of a preformed Vyon tube set inside a perforated PVC piezometer tip. The Model 601 is well suited for water level monitoring, permeability measurements, construction control, de-watering drainage operations, and slope stability investigations. The 601 tip connects to the surface with 3/4” ID PVC riser pipe using slip-fit couplings. Reducer couplings can also be used to connect to other sizes of riser pipe or casing. The standard 601 Piezometer tip lengths available are: 6”, 1 ft, 2 ft and 3 ft (15 cm, 30 cm, 60 cm and 90 cm).

Applications

Isolating discrete zones for:

Water sampling

Hydraulic conductivity testing

Datalogging with a Levelogger

Reducing well development time

Injection of tracers, amendments or other materials

These simple inexpensive packers inflate with a hand pump and are available in 1.8" and 3.7" (46 mm and 94 mm) diameters. Primarily for use in 2" and 4" (50 mm and 100 mm) monitoring wells, they can also be used in smooth boreholes and wells with 1.9 - 5" (48 - 127 mm) internal diameters. Typical inflation pressures for the 1.8" (46 mm) packers are from 20 - 40 psi (140 - 345 kPa) above hydrostatic pressure, and from 20 - 30 psi (140 - 205 kPa) for the 3.7" (94 mm) packers. The Packers utilize a gland of black carbon reinforced rubber (BCR) on a Sch 80 PVC body. They are lowered on flexible low density polyethylene (LDPE) tubing or a rigid PVC drop pipe. If a rigid drop tube is not required for your application, it is recommended to attach a safety line to the eyebolt provided, such as the Solinst Model 103 Tag Line. The inflation line of 1/8" (3 mm) low density polyethylene (LDPE) is easily attached using the nylon compression fittings on each packer.

Datasheet

Silex Selective Passive Skimmer

Applications

Removal of LNAPL

The skimmer is placed at the oil/water interface. A hydrophobic membrane allows LNAPL into the reservoir and rejects water. As the reservoir fills, it sinks into the water. When the reservoir is full a stainless steel suspension cable prevents the skimmer from sinking into the water. Remove the skimmer, empty and reinstall. The Selective Passive does not require an outside source of power or compressed gas to operate.

Datasheet

Silex SPP-3 Combo

Applications

Removal of LNAPL where water level fluctuation is an issue. The SPP-3 Combo can allow for a fluctuation in water level of up to 600 mm.

The SPP-3 Combo is combination of a total fluids pump with a SPG Skimmer (specific gravity skimmer) mounted at the top of the pump. The pump is deployed near the surface of the water at the oil/water interface. The skimmer system then sits in the product layer and the pump is filled with product via plastic float. The float has a lower density than water and a higher density than NAPL so it sits right at the interface. The float sits on a rail 600 mm long with a hose running to the pump. This allows for fluctuations in the water table of up to 600 mm. This design also means that once all of the product has been removed, the pump stops automatically. The pump operates in the same manner as the SPP3/TLC.

Datasheet

Silex High Flow Bladder Pump SPP-CM

Applications

Removal of DNAPL

The SPP-CM is a bottom-filling bladder pump. When deployed, DNAPL enters the pump via a check ball valve at the bottom and fills a Teflon bladder within. Compressed gas is applied to the pump which squeezes the bladder, closing off the check ball valve at the bottom and forcing the DNAPL out the discharge line at the top of the pump. Fill & discharge time and gas pressure are regulated by a controller at the surface. The unit also comes as a top-loading pump for LNAPL recovery.

Datasheet
