APPENDIX B<br />

finished wells shall also be equipped with a lock and shall be protected from the entry of<br />

surface fluids into the well. Protective posts shall not be required on flush-finished wells.<br />

Continuously log soil cuttings throughout the drilling operation in accordance with SOP<br />

B1.1, Borehole and Sample Logging. Document the findings on the soil boring log sheet.<br />

After completion of the well a well alignment test to verify plumbness and integrity of well is<br />

recommended. The recommended method to test well plumbness and alignment is as<br />

follows:<br />

― A 10-ft long section of pipe, ½ inch less in diameter than the inner diameter of the well<br />

riser pipe, shall be run through the entire length of the well to check the alignment. The<br />

result of such test shall be recorded on the Daily Quality Control Reports (DQCRs) and<br />

the installation diagram. The pipe section shall be decontaminated with steam prior to the<br />

test. Adequate precautions shall be taken to prevent cross-contamination of wells with<br />

cable or rope used to conduct the test.<br />

― The pipe must pass freely for the entire depth of the well.<br />

Well construction diagrams will be submitted to the client for approval. These forms will at a minimum<br />

include the following information:<br />

Project and site names, well number and the total depth of the well.<br />

Depth of any grouting or sealing, the amount of cement and/or bentonite used, and the total<br />

depth of the boring.<br />

Depth and type of well casing.<br />

Static water level upon completion of the well and after well development.<br />

Installation date or dates, and name of the driller and the geologist installing the well. Each<br />

installation diagram will be signed by the preparer.<br />

All pertinent construction details of the monitoring wells, such as depth to and description of<br />

all backfill materials installed (such as gravel pack, bentonite, and grout); gradation of gravel<br />

pack; length, location, diameter, slot size, material and manufacturer of well screen(s);<br />

position of centralizers; and location of any blank pipe installed in the well.<br />

Description of surface completion, including protective steel casing, protective pipes, and<br />

concrete surface seal.<br />

A description of any difficulties encountered during well installation.<br />

Survey coordinates and the elevation of top of ground and top of well riser.<br />

A brief stratigraphic log will be presented on the well installation diagram showing depths to<br />

and descriptions of major lithologic changes encountered in the boring.<br />
