This guide should be used in addition to field manuals and instructions appropriate to the chosen sampling device (i.e., HydraSleeve, SpeedBag or Super/Skinny Sleeve and W3 HybridSleeve). Find the appropriate field manual and instructions on the HydraSleeve website at http:// www.hydrasleeve.com.

(McAlary and Barker, 1987). The HydraSleeve can collect samples from wells of any depth, and it can be used for single- event sampling or long-term groundwater monitoring programs. Because of its thin cross section and flexible construction, it can be used in narrow, constricted or damaged wells where rigid sampling devices may not fit. -

Standard Operating Procedure: Sampling Groundwater with the HydraSleeve (patents: 6,481,300; 6,837,120) As with all groundwater sampling devices, HydraSleeves should not be used to collect groundwater samples from wells in which separate (non-aqueous) phase hydrocarbons (i.e., gasoline, diesel fuel or jet fuel) are present because of the possibility of incorporating some of the separate-phase hydrocarbon into the sample. -

0.75” OD and are available in a variety of sizes. An optional top weight may be attached to the top of the HydraSleeve to carry it to depth and to compress it at the bottom of the well (not shown in Figure 1);... -
Page 6: Selecting The Hydrasleeve Size To Meet Site-Specific Sampling Objectives
Selecting the HydraSleeve Size to Meet Site-Specific Sampling Objectives It is important to understand that each HydraSleeve is able to collect a finite volume of sample because, after the HydraSleeve is deployed, you only get one chance to collect an undisturbed sample. -

• The position of the well screen in the well • The total depth of the well The inside diameter of the well is used to determine the appropriate HydraSleeve diameter for use in the well. The other information is used to determine the proper placement of the... -

HydraSleeve be placed in the well so that the bottom weight rests on the bottom of the well and the top of the HydraSleeve is as close to the bottom of the well screen as possible. - Page 9 Figure 3. Incorrect placement of HydraSleeve. This example illustrates one of many types of HydraSleeve placements. More complex placements are discussed in a later section. NOTE: Using smaller diameter HydraSleeves (2-inch) in larger diameter wells (4-inch) causes a slower fill rate.

Note: Alternatively, if spring clips are not being utilized, attach the tether to one (NOT both) of the holes at the top of the Hydrasleeve by tying a knot in the tether. 5. Fold the flaps with the two holes at the bottom of the HydraSleeve together to align the holes and slide the weight clip through the holes. - Page 11 • Situation: The HydraSleeve is deployed for the first time or for only one time in a well The basic HydraSleeve is very thin in cross section and displaces very little water (<100 ml) during deployment so, unlike most other sampling devices, it does not...

HydraSleeve to a very short (approximately 6” to 24”) length, depending on the length and volume of the sampler. This allows the HydraSleeve to fill in a water column only 3’ to 10’ in height (again) depending on the sampler size. Note the SuperSleeves accomplish the same thing but provide greater sample volume at a lower per sample cost. - Page 14 Standard Operating Procedure: Sampling Groundwater with the HydraSleeve (patents: 6,481,300; 6,837,120) Multiple Sampler Deployment Multiple sampler deployment in a single well screen can accomplish two purposes: 1. It can collect additional sample volume to satisfy site or laboratory-specific sample volume requirements.
- Page 15 Standard Operating Procedure: Sampling Groundwater with the HydraSleeve (patents: 6,481,300; 6,837,120) If there is a need for only 2 samplers, they can be installed as follows. The first sampler can be attached to the tether as described above, a second attached to the bottom of the first using your desired length of tether between the two and the weight attached to the bottom of the second sampler (figure 6).

The recovered HydraSleeve and the sample discharge tubing should be disposed as per the solid waste management plan for the site. To prepare for the next sampling event, a new HydraSleeve can be deployed in the well (as described previously) and left in the well until the next sampling event, at which time it can be recovered. -
