Fall Prep

Fall and Winter
Equipment Preparation

As Daylight Savings Time ends, there is no time to lose in getting your field work done. Fourth quarter monitoring and sampling can turn out to be some of the most challenging sampling events of the year. With shorter periods of daylight, there is also a potential for cooling and freezing temperatures as the seasons change and the end of the year draws near. It is very challenging to take water level measurements using the headlights of truck to see the water level meter tape while it’s snowing or raining. Here are some helpful tips we’ve learned over the years from working through some of our seasonal troubleshooting calls.

Some equipment is susceptible to damage when the temperatures approach freezing. Water quality instruments, pumps and Instruments that include pH probes, turbidity standards, reference solutions and water as a storage medium can be irreparably damaged from freezing. This damage can occur if this equipment is riding in the back of a truck during transit, or if stored in your locked vehicle overnight. Damaged equipment, whether owned by your company or on rent, could result in lost billable time and productivity in addition to repair or replacement costs because of the freeze damage. Always store equipment indoors when possible. Securing a ground floor room at your favorite hotel can make a world of difference in mobilizing in the morning.

Winter groundwater sampling

Equipment Limitations:
It’s also important to keep in mind that many manufacturer’s recommendations for proper use of their equipment draw the functionality line at or just above freezing temperatures. This includes using PIDs during drilling or tank excavations for screening soils. Sometimes just taking a PID from a warm running vehicle to a cold job site can cause humidity to fog the PID lamp and generate erroneous or unreliable readings. It may be better to bring the sample to the equipment instead of the other way around. Keeping the PID at a consistent temperature may help keep the project moving along.



Equipment Servicing:
As holidays approach, consider taking advantage of scheduled down-time and send your equipment to Geotech for service, calibration or repair. Geotech services and repairs all of the equipment we sell. Geotech is also a warranty service center for YSI water quality equipment. Take advantage of the time between projects or sampling events and have your equipment fully functional, tested and ready to go! Turnaround times for most service is about a week after the equipment is received, or you can schedule to have the service or repair performed even faster. Our technicians are the best in the industry and our goal is to maintain your equipment to be the most reliable! We document and track everything we service so you can have the confidence the work was performed right. We include calibration certificates with the instruments we service so you have a record of equipment performance. Whether it’s a readiness check, warranty service or a factory cleaning and calibration service, contact your Geotech Account Manager for information on scheduling service today!

Try Before You Buy:
Geotech offers many ways to lower the cost of buying equipment. We offer one of the most generous “Try-Before-You-Buy” programs available. If you are interested in purchasing a new instrument or technology, many of the items we offer in our rental fleet qualify for this program, where up to half of the rental rate is applied toward up to half of the purchase price of the same equipment. Geotech also offers many pieces of equipment at “Pre-Owned” prices. As a manufacturer, we maintain the equipment we make and sell at the highest level possible in our rental fleet. Sometimes we offer this used rental equipment for sale. Please check with your Geotech Account Manager for available equipment.

Seasonal Tip:
Sometimes the simplest of equipment can help make this time of year more comfortable while working outdoors. Thermal glove liners are inexpensive, disposable and fit beneath your latex or nitrile gloves. Cold water and frozen fingers make for a miserable sampling event. Geotech is a provider of all your consumable field equipment needs, including gloves, glove liners, "Rite in the Rain"® field books, copy paper and pens, calibration standards for air and water quality equipment, tubing, filters, bailers, bailer string and more! We have nine regional service centers to serve you which in most cases are only one to two days shipping away.

Let Geotech help you plan ahead! We pride ourselves on looking out for our clients to help manage your equipment service and calibrations, at the best value. We have locations to serve you in Colorado, Texas, Northern and Southern California, Washington, Vermont, Florida, Michigan and North Carolina. In-store training is always no-charge to our clients, so let us help ensure the success of your field sampling event. And if you are passing through Denver, stop by for a tour of our world-class ISO certified, Lean Manufacturing facility.

Geotech October 2014 Photo Competition Winner

Carissa Watanabe, an environmental scientist for BergerABAM, is collecting groundwater samples from a monitoring well for the Mukilteo Multimodal Project located off the Puget Sound. Water samples are pumped from the well using a Geotech geopump™ peristaltic pump. A Geotech ET Water Level Meter is being used to record the depth of the water in the well.
The Geotech equipment came from our new Kirkland, WA Service Center.
