In this ISSUE T he July issue of Water Well Journal focuses on heavy equipment and features WWJ's annual heavy equipment directory. The "2015 Heavy Equipment Directory" found on page 30 features product details and contact information for industry manufacturers of drilling rigs, water trucks/rig tenders, pump hoists/service trucks, mud recycling systems, and compres- sors. It is a one-stop shop for you when it's time to make that next important pur- chase for your company. Freelance writer Jennifer Strawn begins a two-part series on how to make sure corrosion doesn't cut into the life of your heavy equipment with the feature article, "Combating Corrosion" on page 20. This first installment covers pitting and uni- form corrosion, while part two in August will detail crevice and galvanic corrosion. Strawn explains how both types of corrosion can eat away at your drill rigs and trucks, what manufacturers are doing to prevent it, and how you can slow the pro- gression of corrosion as well. She stresses the importance of staying on top of corrosion control by pointing out losing equipment to rust when key parts are still operational is a problem that eats away at your bottom line. Senior Editor Mike Price provides tips on choosing the right drill bit for your job in the feature article on page 26 titled "Choosing the Right Drill Bit." Price speaks with water well contractors who weigh in with their personal experi- ence selecting and working with their drill bits. One contractor from Indiana gives his checklist when selecting his drill bit for his area's geologic formation and lists practical maintenance reminders for the bits. A couple of drill bit manufacturers also share their experience working with contractors and offer advice to water well contractors. As one manufacturer states, "The key is to drill faster at a lower cost per foot," which doesn't always mean choosing the most expensive or the least expensive drill bit. This month's installment of Safety Matters is authored by Gary Ganson, CIH, CSP, and warns prosecutions are up against companies whose negligence leads to fatalities in the workplace. Titled "Criminal Charges Filed" and beginning on page 40, Ganson writes the Occupational Safety and Health Administration had only eight fatality cases result- ing in felony prosecution of management and owners in its first 30 years. However, over the past 10 years there has been an increase in the number of prosecuted cases as well as state laws enacted that can levy criminal charges against owners and management staff. Ganson goes over how penalties have been significantly strengthened, recent prosecutions, as well as well as ways to focus on preventing accidents that can lead to fatalities. Engineering Your Business columnist Ed Butts, PE, CPI, begins a three-part se- ries this month titled "What You Should Really Know About Pumps." Beginning on page 42, the first part focuses on the practical components of a pumping system. Butts states having command of the practical components of a pump can help you troubleshoot systems. He goes over classes of pumps, determining horsepower, reading pump curves, understand- ing suction problems, and working with affinity laws. In explaining the different components, he provides samples which help illustrate the terms and technology. The second installment of the series will appear in the August issue and discuss diagnostic characteristics of drivers, most notably the electric motors used to actu- ally operate the pumps. The final installment in September will provide an overview on the controls and ancillary devices used as an interface between the operating environment, namely water, and the pump and motors used to deliver the water.
