| Preliminary
Findings: (From Inititation) |
| Site: |
XYZ Enterprises, Allsorts Industrial
Park. |
| Current land uses: |
Currently used as an industrial storage
facility with around 60% of the site in bare soil, 20% with a gravel chip
surface cover, and 20% of the site with a concrete slab/building cover. |
| Historic land uses: |
Based on the Certificate of Title and aerial
photos, the land was originally pasture, and then developed by a sawmilling
company as a timber processing yard. Building consents indicate that the
site underwent upgrades. The date of timber treatment plant installation is
uncertain but possibly from the early 1970s. The use of boron is uncertain
but use of PCP is unlikely as a nearby site owned by the same company
apparently undertook this task (see records for STU Ltd). A diesel-fired
boiler is used and there appears to be an underground diesel storage tank at
the site. Unconfirmed reports of waste dumping on the bank of the
river. |
| Potential contaminants: |
Copper, chromium, arsenic, boron, diesel. |
| Potential pathways: |
Based on regional council information,
groundwater beneath the site is shallow at 2 m. Groundwater is overlain
with a 2-m-thick confining layer. Groundwater contamination is considered
unlikely but information is not available for this site specifically. The
ABC River is located on the eastern corner of the site and the site slopes
towards this corner. |
| Potential receptors: |
Downstream river biota, downstream river users,
down-gradient groundwater users, riparian biota, wetland biota. |
