For several years there has been wide
concern among our member-professionals all over HRM with respect to the
long term impacts of STPs (sewage/wastewater treatment plants). The
probable impact of an STP on a freshwater lake can be quite
significant, especially during the summer months when the lakes do not
flush appreciably.
While the design of an STP is the domain of a professional engineer, the professional who has the credibility in the scientific evaluation is a limnologist.
Inserted below is a 12-page published paper of a leading limnologist, Joe Kerekes PhD, Scientist-Emeritus with Environment Canada Atlantic, Dartmouth. Dr. Kerekes was also one of the leading scientists who headed the international OECD (Organization for Economic Co-Operation & Development) peer consensus standards-development.
In this published paper, Dr. Kerekes carries out an intensive scientific analysis of the impact of a proposed secondary-level package STP prior to its installation at a development site which drains into Freshwater Lake, Cape Breton Highlands National Park. He warns against secondary treatment as that would result in the Freshwater Lake becoming `Mesotrophic’, its management objective being `Oligotrophy’!!
