Well water (groundwater) is water that is used for public supply, individual household use, irrigation, aquaculture and agriculture and mining, among other smaller things. Roughly 37% of the water used for county and city water departments to supply households and businesses is groundwater. Groundwater provides drinking water to approximately 90% of the rural population and 42% for irrigation in the United States. Groundwater is exposed to a number of potential volatile organic compounds (VOC’s). For example, a gas station, construction site or farm that uses chemicals can allow volatile organic compounds (VOC’s) to seep into the ground and contaminate groundwater. Furthermore, sometimes wells are placed in sites that were once used to hold septic tanks or the like, and still house a number of different bacteria.
Manufacturing, Cleaning, Special Cleaning and Production Procedure.
Products Included: All SingleSample polyethylene and PTFE products
Conventional, reusable PTFE bailers are hand machined out of solid rod and block stock in a machine shop environment which potentially exposes them to volatile compounds. The result is a product that, from its initial manufacture, requires decontamination.
SingleSample PTFE and polyethylene disposable bailers are produced under entirely different conditions. The top piece, bottom valve and removal device are injection molded and all tubing is extruded. (These processes all take place off-site from the assembly facility.) Since PTFE and polyethylene are naturally slick, there are no lubricants of any kind used in any of these processes.
Polyethylene Material Specifications.
The resin in all Single-Sample polyethylene products is natural, virgin, high-density polyethylene. No regrinds are accepted and the same material is used consistently from run to run. The polyethylene used in SingleSample products contains no plasticizers or additives.
Once the parts are molded or extruded, they are packaged and shipped directly to the assembly facility. Immediately prior to assembly, all parts and tubing are washed in LiquinoxTM Detergent and individually rinsed with DI water. This is a precautionary step taken to remove any traces of compounds that may have found their way onto the tube through touch-transfer or other means in the manufacturing phase of production.
After the wash and rinse step, all parts and tubing are allowed to air dry in a controlled room. After drying, these parts are assembled and individually inserted into polyethylene bags. These are 2 mil. thickness bags that do not require or contain any plasticizers.
After bagging, bailers are packed in natural corrugated boxes that are assembled using exterior tape only to eliminate glues containing volatiles that are sometimes used in corrugated boxes.
Special Cleaning Procedures.
The following special cleaning procedure is available for SingleSample bailers. This cleaning procedure supplements the regular manufacturing and cleaning procedure and all steps not outlined here remain unchanged.
Under this procedure, all components are:
- Washed thoroughly with Liquinox laboratory detergent.
- Rinsed with DI water.
- Rinsed with 10% Nitric Acid solution.
- Rinsed thoroughly with DI water.
- Rinsed with Isopropanol.
- Dried in closed room.
