Lab Facilities
Updated: 14 December 2015
Delta Environmental Consulting has a well equipped private laboratory containing spectrophotometric, gravimetric and respirometric equipment for water and soil testing, differential interference contrast photomicroscopy for phytoplankton and zooplankton studies, stereoscopy for aquatic macroinvertebrate, entomological and flora studies, as well as a range of microbiological (bacterial and fungal) collection and incubation equipment for testing microbial water and microbial air quality. We do not offer ICP-OES, MS or AAS methods.
We are set up to test for the parameters most often required in our consulting clients' projects.This enables us to provide extremely rapid turnaround and is economical for our clients. As part of large projects we are happy to discuss undertaking other analyses not described here that are within the capacity of our equipment.
WE NO LONGER OFFER SOIL & WATER TESTING SERVICES TO THE GENERAL PUBLIC.
The prices and analyses listed below are provided to inform clients who are looking at ongoing projects with us of the cost component of any analytical services that we may perform as part of the consulting or research project. Starred * items may only be availalbe if a minimum number of samples can be guaranteed, or in the case of bacterial media, may have a lead time to obtain fresh media.
