Part of the abandoned mine site cleanup process requires benthic macroinvertebrate enumeration to assess potential impacts from former mining activities. This process requires a high-quality laboratory with extensive experience in identifying species in various Pacific Northwest montane stream ecosystems. Aquatic Biology Associates, Inc. has provided us with the requisite high-quality service at reasonable prices. Mr. Wisseman is exceptionally knowledgeable and always provides personal attention to assist us with site-specific abandoned mine cleanup options. Thank you, Mr. Wisseman. I look forward to working with ABA on future mine cleanup projects.
