Province / Territory:  Newfoundland & Labrador
Funding Source:  Federal and Provincial
Year of Collection:  1987

Survey Type:  Regional Lake & Stream Survey
# Lake sites:  176

The infill stream and lake survey for eastern Labrador (parts of NTS 13J and 13O) was conducted during the summer of 1987.

This report presents analytical and statistical data for 20 elements in stream and lake sediments from 309 sample sites, collected at an average density of one sample per 3 to 5 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
