GHD Saves Valuable Time by Using ALS Compass for Field Sampling Projects
Posted 04 November 2019
The ClientGHD is one of the world’s leading professional services companies operating in the global market sectors of water, energy and resources, environment, property and buildings, and transportation. They provide engineering, architecture, environmental, construction and advisory services to private and public sector clients.
The ChallengeTo help their clients, GHD was looking for a way to reduce time-consuming tasks such as labelling, double checking, and putting on hold large amounts of samples for a drilling investigation program. These tasks had the potential to result in mistakes and impact the quality of results for their clients.
The SolutionAfter GHD expressed interest in trialling ALS Compass for their field sampling, a two-hour training session was set up between ALS and GHD to explain how to use the app. The first time GHD used the app in the field, it was for an existing program that had few modifications on the original quotes. “It took a few times to have the project set up correctly in the app, however the time spent prior to the field deployment was quickly offset by the time saved on the field as we sampled more than 180 soil samples and 50 groundwater samples.”
GHD found the bar code scanner in ALS Compass to be a highlight of the app, as well as the ability to quickly tag potential risks (such as high HC concentration, potential asbestos, etc.) for ALS laboratory workers who handle the samples.
“ALS Compass is a fantastic tool to reach a paperless target in the field. After using the app, it is hard to go back to the old days of labelling bottles.”

The ResultsALS Compass was able to provide the time-saving features and quality assurance that GHD was looking for in a field sampling app. For complex monitoring projects, it proved valuable to have an automatic notification sent to the Project Manager, so they could review the COC prior to the lab processing the samples. “By reducing the amount of time spent on labelling/managing the samples and producing the COC, we can maintain our focus on safety while on-site and have better communication with contractors (if present) and follow the SAP and QA/QC requirements.”
With the possibility to create new sample locations in the field, GHD was able to sample additional locations from a drain, at the client’s request, during a quarterly GME at a landfill. “It took us less than five minutes to add the location in ALS Compass, assign the analysis suite and with the GPS feature, we could quickly update the location in our figure and database.”
During a project for further delineation of a LNAPL plume contamination, GHD had to drill 10 monitoring wells to a target depth of 15 meters. In addition to the investigation of hydrocarbon contamination at the site, PFAS contamination was looked at in the upper layer of the site. With a limited budget for the analysis of certain concerning pollutants, a large number of samples had to be put on hold while making sure various depths for each contaminant were covered. “With ALS Compass, we quickly covered the fill and upper layers for the PFAS investigation for the different BH while focusing on the saturated zone for the hydrocarbon contamination. Due to the remote aspect of the site, we were able to quickly get the samples ready in the eskies prior to the courier deadlines.”
