Project Description: This research will help address growing concerns over the use of sumps as a disposal option for drilling waste in the Inuvialuit Settlement Region and is a first step in evaluating the environmental conditions at historic sump sites. The specific objectives of this research include: 1) conducting an inventory of all known specified drilling sump locations within the ISR (including location, last known operator, spud and sump closure date, identification of orphan locations, well description); 2) develop a protocol based on site assessment and risk ranking process; and 3) conduct site assessments using the protocol at company specific sites.

A three-member team, including two technical staff and one wildlife monitor (hired locally) will access each site via Inuvik using an A-star helicopter (hired locally). Field methods for site assessment include: airphotos of the general sites and site features (any ponding, vegetation stress, general terrain); collection of a site description including any debris on site, gravel pads, vegetation growth, wellhead, description of slumping or subsidence; vegetation assessment; soil samples collected with hand equipment (1 or 2 background samples per site and other areas with visible surface impact); water samples from any area with ponding / pooling (estimated maximum of 4 water samples / site); collection of geographical reference and EM surveys using portable conductivity meters.

As per work conducted in 2004, a 200 word non technical summary will be provided to the Aurora Research Institute (ARI) by June 2006. In addition, copies of all final reports will be forwarded to the ARI.
The study will be conducted at Northing Easting
