Priddis has been monitoring wildlife around Adams Lake since the Spring of 2012. Priddis conducted a field water quality assessment in May of 2015. The investigation found no water quality issues. Priddis plans to conduct a vegetative health assessment in the near future.
Priddis has been working in the Northwest Territories for over 10 years managing the Mackenzie Delta Spill Response Corporation (MDSRC). For three of those years we also worked on the remediation and reclamation of drilling waste sumps and provided environmental support to an exploration drilling company.
The sites we were responsible for were in areas surrounding Norman Wells, Inuvik, the Mackenzie Delta, and in the environmentally protected Kendall Island Bird Sanctuary. The sites were accessible by helicopter only and required detailed logistical planning to ensure equipment, supplies, and personnel were efficiently expedited and utilized to control costs and manage time.
We have developed many relationships with local community members, businesses, and government which enable us to effectively plan and execute projects in the NWT. Through these and other strategic partnerships, Priddis was able to develop plans that saw reductions in soil contamination, an increase in plant growth, retardation of soil erosion, and monitoring for sump stability.
We are registered with the WCSS, are a Shipper of Record, and have a Permit to Practice in the NWT. All of these things combined gives our clients the comfort in knowing that they are getting quality work that is done safely and with the due diligence of companies working in the south.
Assessment and Reclamation of abandoned wellsite near Hanna, AB:
A well was drilled near Hanna in the 1990s. The production facilities included a flare pit, dehydration facilities and tanks. There was evidence of a former spill. The drilling waste met the current drilling waste guidelines; a Phase II ESA was conducted on the suspected former production and spill areas. The Phase II ESA found elevated levels of selenium in some onsite samples, compared to the controls and the applicable guidelines. However, based on the literature review, the selenium exceedance was consistent with naturally-occurring coal bed formations. In addition, the wellsite had been seeded to invasive species during reclamation. The invasive species was mapped and selectively removed over time. A Non-Routine Reclamation Certificate was submitted and approved.
Reclamation of drilling waste disposal site near Edmonton, AB:
A well was drilled and abandoned near Edmonton. The gel chemical drilling waste was disposed of via Landspray-While-Drilling. A Phase I ESA was conducted, and a Phase II ESA was not required. The site passed the Detailed Site Assessment and a Reclamation Certificate was received. An Alberta Environment (AENV) Audit was conducted, which found three onsite boreholes with elevated electrical conductivity (EC) when compared to the applicable guidelines. As a result of the findings, the Reclamation Certificate was cancelled. The Operator was notified and follow-up action was required. A Phase II ESA was conducted, which included a significant number of control samples and resampling the three Audit boreholes of concern. The soil chemistry indicated that elevated EC values were likely naturally occurring. The soil was heterogeneous onsite and offsite. A meeting with AENV director to discuss the investigation resulted in the Reclamation Certificate being reinstated.
