Aqua Bailers, Inc.

Aqua Bailers, Inc.

In September 1994, Aqua Bailers, Inc. began producing and distributing a variety of groundwater bailers to clients worldwide. Environmental specialists, well drillers, and others with groundwater sampling needs were drawn to the company because of high quality control standards and excellent customer service. The 1.5” by 12”, 36” and 48” poly bailer in both weighted and non-weighted style were an immediate success, but it was clear that innovation would drive the growing business. Since then, the product line has been expanded to include ½“ and ¾“ mini bailers to fulfill smaller well sampling needs and a 3.5” Biggie Bailer to quickly sample larger wells. Groundwater bailers are now available in a variety of lengths and materials including HDPE (Poly), clear PVC, and FEP (Teflon).

Year Founded:


In addition to manufacturing disposable bailers, we offer a wide variety of permanent bailers, gloves, cordage, anionic detergents (used for manual and ultrasonic cleaning), and groundwater sampling accessories.

Superior quality and service since 1994.

The greatest innovation came in 2005 with the creation of the SinkFast Bailer, which combined the benefits of a clear PVC bailer with the cost savings of HDPE (Poly). Since then, it has stood out as the fastest-sinking single-weighted bailer on the market with excellent sample integrity. It is constructed of 100% virgin material and backed by the trusted reputation of Aqua Bailers.

In addition to the extensive line of bailer products, Aqua Bailers also stocks groundwater sampling accessories, such as filters, gloves, cordage, cleaning supplies and Rite in the Rain writing supplies. Aqua Bailers has continued to offer its clients superior products and customer service, allowing it to become one of the top bailer manufacturers in the world. By entering new markets, innovating new products, and maintaining the highest standards of quality and customer satisfaction, Aqua Bailers continues to gain global market share and build strong client relationships.

Environmental Quality Standards. Since environmental consultants use bailers to obtain water samples that are representative of an area’s ground water, it is crucial that the bailers used in the field are free of any potential contaminants and held to the strictest quality standards possible.

While it is up to regulatory agencies, environmental organizations and field technicians to establish and follow protocol for the retrieval of ground water samples, it is Aqua Bailers’ obligation to manufacture a bailer that meets or exceeds standards for durability, reliability and most importantly, sample integrity.

Vendor Selection. The manufacturers of Aqua Bailers’ components (e.g., parts, tubes, balls, etc.) are as vital to a quality bailer as the cleaning and assembly processes followed by Aqua Bailers. Any variation in the size of a part (as little as a thousandth of an inch) can result in a leaky bailer, causing delays or compromised samples. Therefore, Aqua Bailers’ vendors are held to the strictest manufacturing specifications possible.

Material Selection. The selection of bailer component materials has a great impact on sample integrity as well as ease of use in the field. Aqua Bailers’ components are only manufactured with approved, 100% virgin materials, such as FEP, HDPE and PVC.

Cleaning/Drying/Assembling/Packaging. Proper and thorough cleaning of bailer components prior to assembly is critical to manufacturing a quality bailer; that’s why personnel wear powder-free nitrile gloves at each stage of the assembly process. All bailer components are cleaned pre-assembly with laboratory-grade, phosphate-free detergent and given a final rinse with de-ionized water before drying. The cleaning, drying and assembly processes are performed in three separate pressure-positive rooms to minimize the possibility of airborne contaminants. After assembly, each bailer is individually sealed within 3 mm polyethylene bags prior to boxing. Every case of bailers and slow-emptying devices (a.k.a., VOC Tips) is labeled with a 6-character quality code. This code allows Aqua Bailers to trace a manufactured product back to the actual day of production to ensure correction of any component quality issues that may arise. 

Testing. Aqua Bailers’ product standards are defined by superior field performance and superior sample integrity. Superior field performance is tested via destructive examination (DE) and non-destructive examination (NDE). Prior to packaging, assembled bailers are randomly and periodically tested to ensure they can withstand rigorous field use. Environmental consultants charged with the responsibility of analyzing ground water for contaminant levels as (minimal as parts per billion) need assurance that the equipment they use will not affect the sample. Optimizing sample integrity requires periodic independent laboratory testing of randomly selected assembled, pre-packaged bailers. Since each sampling event may be unique, no one laboratory test covers every consultant’s individual requirements. For example, Test Method 8260B is appropriate when testing for trace levels of volatile organic compounds, but does not include metals. Aqua Bailers periodically tests its bailers to ensure a below-detection-limit (BDL) result for a wide range of analytes including, but not limited to, all RCRA Priority I Pollutants. Contact Aqua Bailers directly for specific third-party test results.

Products are not to be returned, nor will they be received, without express permission from Aqua Bailers prior to returning. Contact the office for details on returning defective products.
