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

with waterra wellcaps

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...more

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

with waterra pumps & bailers

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

In the last few years, the popularity of establishing piezometers using drive point technology has increased substantially. The concept is to drive a hard point into the ground to establish a shallow piezometer. ....more

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). Naturally the presence of these products is not a good thing and it is of keen interest to establish their presence and if so how much product is present.

with the waterra inline disposable 0.45 micron filters

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 philosphy is to remove suspended particulate matter that may contain or carry metals. ...more

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 and allow fresh formation water to fill the well prior to sampling. Numerous clients report that they purge the equivalent of three well volumes prior to sampling, but protocols vary. ...more

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

with the waterra inertial pump and VOC sampling kit

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, and through the sampling process these compounds may escape from the water. ...more

with the waterra water level sensors

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 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

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 a permeable formation that carries material into the well, or it may be surface derived material that ends up in the well in any number of ways. ...more
