In this ISSUE T he February issue of Water Well Journal focuses on ground source heat pumps and contains two feature articles and a column on the subject. The first feature article is designed to aid geothermal system installers in figuring out what system is best for their customers. Authored by Jeff Persons, CGD, the ar- ticle is the first in a two-part series and is titled "Open Loop Geothermal System Survey." It begins on page 15. Persons goes over items every system designer must do and then provides a sur- vey of questions that must be answered to ensure the best system will be installed for its owner. Among his tips are reviewing well logs, going over the construction of the well and the formation it was drilled in, and reviewing the water quality. The questions he asks in his survey are related to water quality. Among them are: Is there a water softener? Is there a filter canister before the water softener? Are there any spent filters available for viewing? Freelance writer Jennifer Strawn authors the feature article titled "Don't Lose Your Shirt" on page 19. It states what many contractors working in geothermal already know—that when bidding on a job it is easy to have a competitor swoop in with a bid significantly lower than yours. She cautions in the race to get jobs it can be easy to overlook costly details, lead- ing you to lose money. She then goes over five mistakes you don't want to make when you're getting ready to bid a job. Not doing your homework and ignoring hidden costs are among the mistakes she cites. She provides details and talks to contractors from around the country about each. The latest installment of the Engineering Your Business column also covers geo- thermal. Columnist Ed Butts, PE, CPI, begins a two-part series with an article titled "Geothermal Supply and Recovery System Using a Groundwater Source" on page 36. The two articles will detail a project Butts' company worked on. The project involved a community with a variety of housing types where ground- water could be the sole water supply for a parallel configuration of water-to-air heat pumps in each individual residence and large facilities, such as a greenhouse and community center, for heating and cooling purposes, as well as retaining the groundwater for irrigation and potentially for potable water supply. This article goes over the planning of the job and the investiga- tion of the existing water supply. The investigation included video surveys of an existing well on the property, determination of the well's physical characteristics, aquifer analysis, and water quality testing. A feature story by Tom Moffitt details a project recap where contractors had to use environmentally responsible drilling practices because they were in a threatened species habitat area. In "When a Tortoise Needs More Than a Shell for Protec- tion" on page 26, Moffitt tells the story of AZCA Drilling & Pump Inc., which had a job in southeastern California for a solar energy provider where it had to drill carefully as it was in the home of desert tortoises. Drilling in a threatened species habitat in a California Desert Conservation Area administered by the federal Bureau of Land Management meant heavy restrictions on AZCA's site access and drilling techniques. Senior Editor Mike Price recaps the 2014 NGWA ® Groundwater Expo and Annual Meeting, which was back in Las Vegas and took place December 9-12. The 66th NGWA Expo drew a total attendance of 5245 and spanned all sectors of the groundwater industry—water well contractors, manufacturers, suppliers, and scientists and engi- neers. In "What a Return" on page 30, Price details how the Expo achieved its strongest show since 2008, speaking with attendees, exhibitors, and NGWA staff about the groundwater industry's largest event.
