Selenium Fish Tissue Sampling

Selenium Fish Tissue Sampling

Many NPDES Permits now contain a Selenium Fish Tissue sampling trigger for collection of fish and application of EPA Method 200.8. This method identifies the amount of Selenium accumulated in the tissue of certain fish species. Biological Systems Consultants’ selenium fish sampling team is equipped to take on all of your fish survey needs. Our staff is fully permitted and qualified to conduct Selenium Fish Surveys. If you have any questions about your Section 402 NPDES permit conditions or compliance  or have been requested to collect selenium fish tissue samples on your project for any reason Contact us or request a quote today.

This methodology is outlined in the Methods for the Collection of Selenium Residue in Fish Tissue Used to Determine KPDES Permit Compliance SOP manual published by the Commonwealth of Kentucky Energy and Environment Cabinet, Department for Environmental Protection, Division of Water (KDOW, 2014).

Bioassessments & Benthic Macroinvertebrates

Waterfall / Step Pool / Stream Assessments

Bioassessments & Benthic Macroinvertebrates collections were conducted this week and we had to share some photos from the field during the macroinvertebrate surveys in Harlan County, Kentucky. The above average rainfall in May 2016 revealed breathtaking waterfalls in this watershed.
