Correction: Environmental engineering list

The Environmental Engineering/Science Consulting Firms list, which appeared in the June 30 issue of SBj, was in error due to misinterpretation of the list questionnaire. Gerken Environmental Enterprises has eight professional staff, making it No. 8 on the lsit. Environmental Works Inc., with 29 professionals, is now ranked No. 1, and subsequent companies move up one place in the ranking. Professional staff is measured by the number of staff who qualify as |quot|engineers, chemists, geologists, hydrologists, etc.|quot|
