In this ISSUE T he April issue of Water Well Journal focuses on water quality and water treat- ment with multiple feature stories on the subjects designed to help you when you head to the job site. Authors Christopher Johnson, PG, CHg, and Michael Schnieders, PG, PH-GW, have combined on the feature story "Well Development Is Efficiency Develop- ment," which begins on page 23. They point out well development is not a second- ary issue, but rather a key element that sets the stage for the well, defining whether it will be a problem child or an asset. They state the process is really developing efficiency and involves all the steps necessary to increase the well's efficiency to acceptable standards. Johnson and Schnieders explain the consequences of improper or inadequate development are a well system producing less water or one using far more energy than an efficient system. They then explain how to effectively develop a well. Senior Editor Mike Price begins a three-part series on major U.S. aquifers in the cover story "Aquifers in the United States" on page 17. Part one focuses on the Floridan aquifer system, which underlies the entire state of Florida as well as southern portions of Alabama, Georgia, and South Carolina. It covers 100,000 square miles and is the largest aquifer in the southeastern United States. Price covers challenges faced drilling in the artesian aquifer, water quality of the aquifer, the water well permitting process, a water initiative, and the state's efforts in aquifer storage and recovery. In the accompanying sidebar article, the National Ground Water Association points to managed aquifer recharge, also known as aquifer storage and recovery, as an important infrastructure tool to cope with expected water shortages. Columnist Ed Butts, PE, CPI, wraps up a two-part series on flowmeters in his monthly installment of Engineering Your Business on page 36. In "Flow Measure- ment Techniques," he details electronic methods of reading flow after having cov- ered mechanical flowmeters in the March WWJ. Butts goes over the different measurements that can be recorded by electronic flowmeters, the most common types of meters and their strengths and weaknesses, and how to choose the proper meter for your job. He ends on a note that recent technological improvements can mean that meters ideal for an application years ago may not be the right choice anymore. The article includes a table with pertinent information on a variety of electronic flowmeters. Freelance writer Lana Straub covers a drilling method not used by many water well contractors, but one that can prove ideal for some jobs in the feature story "Angled Wells" on page 29. In a roundtable discussion, she talks about the niche topic with four groundwater professionals: two contractors who use the method from time to time, as well as a geologist and a professor. They all explain the technique, offer details on when drilling at an angle or horizontally can help provide hard-to-reach water to a source, and tips on how to do so. The monthly column Safety Matters warns of the dangers workers face overhead in "Safety Around Power Lines" on page 33. Author Jerome E. Spear, CSP, CIH, begins the column by stating the most common cause of fatalities on cranes or other high-reaching equip- ment is contact with overhead power lines, as electrocutions account for one-third of crane-related fatalities. Spear then explains the Occupational Safety and Health Adminis- tration's Final Rule for Cranes and Derricks in Construction, ways to assess the hazards at a job site, how to keep a crew at a distance or even eliminate the hazard, and what to do if a power line is hit on the job.
