In this ISSUE T he September issue of Water Well Journal focuses on heavy equipment and features WWJ 's annual heavy equipment directory. The "2016 Heavy Equipment Directory" found on page 31 features product details and contact information for industry manufacturers of drilling rigs, water trucks/rig tenders, pump hoists/service trucks, and backhoes/trenchers. It is a one- stop shop for you when it's time to make that next important purchase for your company. Freelance writer Jennifer Strawn covers disposing of drilling spoils in a feature story titled "A Solid Choice" on page 19. Disposing of spoils can get tough on occasion, and when that is the case, solidification may be an option ideal for the job. There are different options when it comes to disposing of drilling spoils, including hauling liquid waste, centrifuge dewatering, land/farming applications, and solidification. Strawn points out no one option is best and the right choice may depend on the job. She adds solidification is one to consider when regulations or size of the job hinder the other options and goes over how to solidify spoils from a drilling job. In the latest installment of Drawing from the Well, columnist Gary Shawver, MGWC, discusses why grouting is vital to ensure safe drinking water for users of well systems in the column titled "Grouting Isn't 'Just Grouting'" on page 46. Shawver maintains one can drill the straightest hole, put in the best casing to the proper depth, use a good screen and gravel pack, etc., but if they don't do a good grout job, they haven't really provided anything for their customer. His column then goes over cement- and bentonite-based grouts, their characteristics, and their advantages for use in certain settings. Shawver points out both have their place and his firm uses both, depending on the job site setting. WWJ Senior Editor Mike Price talks with Kevin Christensen, president of Palmer Bit Co. in Williston, North Dakota, in a Water Well Journal Q&A on page 22. The Q&A centers on a topic which hasn't been covered in recent memory—the cost savings of retipping drill bits and how to tell when to send them in for repair. Christensen estimates close to 40% of his business is the retipping of drill bits. He believes it should be higher if contractors were more focused on the upkeep of their bits. When it comes to bit mainte- nance, Christensen says contractors weigh the time spent tripping out of a borehole against saving bit costs. In the sidebar article David Henrich, CWD/PI, CVCLD, vice president of Bergerson-Caswell Inc. in Maple Plain, Minnesota, discusses the cost savings his company finds using refurbished bits as opposed to new ones. Columnist Jerome Spear, CSP, CIH, covers the important topic of exposure to noise in this month's Safety Matters on page 48. In the column titled "Controlling Noise" he points out there is no cure for noise-induced hearing loss and noise can have both hearing and non-hearing-related health effects. Therefore, he writes, preventing excessive exposure to noise is the only way to preserve your hearing. He examines in detail the three ways to reduce and control workers' exposure to noise. Engineering controls are modifications or replacement of equipment and modifications of the noise source. Administrative controls involve changes in the work schedule or operations that reduce workers being exposed to noise. Personal protective equipment is the use of hearing protectors to reduce the level of noise such as earplugs and earmuffs.
