The equipment that Waterra provides is suitable for a wide variety of applications that go well beyond purging and sampling monitoring wells. A range of these applications and special situations and the equipment suitable for use in them are listed below.

bailing

In some situations sampling pumps may not be suitable for purging or sampling some wells. These situations could arise as a result of budget limitations, site logistics or even monitoring well characteristics. ...more

capping wells

Monitoring wells should always be capped in order to prevent foreign material from contaminating the well. Often the simplest method used to cap monitoring wells is to place a blind end cap over the open end of the well. These caps, however, do not provide any security for the monitoring well. ...more

collapsed wells

Piezometers or wells that have lost their original diameter as a result of collapse or obstruction by other equipment can continue to be sampled with the Waterra Inertial Pump. ...more

conventional sampling

Waterra currently offers three devices that can be used to collect samples of groundwater: the Waterra Inertial Pump, Waterra Disposable Bailers and the Waterra 12 Volt Submersible Pump. These products offer different features that cover most sampling needs in a broad range of sampling environments. ...more

drive point sampling

In the last few years, the popularity of establishing piezometers using drive point technology has increased substantially. ...more

hydrocarbon detection & measurement
(LNAPL, DNAPL)

Unfortunately there are many sites where the groundwater is contaminated with hydrocarbon products. Some of these products are lighter than water (floaters) and some of them are heavier than water (sinkers). ...more

metals sampling

Many jurisdictions specify that groundwater samples that are collected for the purpose of determining metal content must be passed through a filter having a 0.45 micron pore size. The philosophy is to remove suspended particulate matter that may contain or carry metals. ...more

purging

Purging, in the groundwater context, is the removal of volumes of well water. One may want to purge to remove the stagnant standing water from the well. ...more

surging

Surging is the process of creating a larger than usual flow through a screened interval usually with the goal of cleaning out smaller particulate matter or biological matter from the filter pack and/or adjacent formation. ...more

VOC sampling

It is a frequent requirement of groundwater monitoring programs to sample for the presence of volatile organic compounds (VOC) in groundwater. This can be a complicated procedure because these compounds are by definition volatile. ...more

water level detection

When groundwater investigators go to the field, one of the first things that they do is to remove the well cap from the well and then look down the well. Mostly what they see is black nothingness and even if they could see the water level, they still would not know the depth below grade of the water table. ...more

well development

Well development is an important part of monitoring well procedures and is usually required in order to acquire a quality sample and adequately determine formation parameters such as permeability. ...more

well sediment removal

It is very common to come across wells that are filling up with sediment. The sediment may be derived from the sides of the well (especially if it is an open well), or it may be derived from. ...more
