Water Quality

Select scientific modelling and chemical/biological limnology are part of our miscellaneous archives

The bathymetric map; the basic morphological data; the location map; the Nova Scotia lake hypolimnion project; the paleolimnology of lakes in the HRM

 Maynard Lake was used as a drinking water supply long ago; Thank you Mr. Kenneth Manuel.

But in the case of Maynard Lake, there is good news as follows:-

Through the combined efforts spearheaded by ourselves with strong public support and with several Government agencies partnering with us, we herewith announce significant improvement in several indicators inclusive of the summer-2004 E.coli counts, sublittoral zoobenthos, lake phycology, and other parameters.

In addition, an experimental project carried out several years ago by the DFO at Bell and Maynard Lakes concluded that the control brook trout fingerlings survived well in Maynard Lake while the survival rate was poor at Bell Lake.

 It is cautioned though that the low E.coli counts may not be sustainable unless citizens do their part in not feeding ducks.

The original history from early-to-mid-1900s when Maynard Lake was used as a drinking water supply. Thank you Mr. Kenneth Manuel for the info:-

Bacterial Source Tracking and related events, 2002 to 2004

Bacterial Source Tracking (BST) of the lead indicators, Bacteroides Prevotella species, the first ever BST carried out in all of the Province:

• BST results from the world-class expert, Prof. Kate Field PhD
  • High recommendations from independant international regulators on Prof. Field's methodology

• Encouragement from the Hon. David Morse, Minister, Nova Scotia Dept. of Environment & Labour (NSEL)

• ....... with salutations to John Sheppard PEng, Manager of the EMS Dept. of the HRM; to the former Deputy Minister of NS Dept. of Environment & Labour, Ron L'Esperance; and to the former HRM Councillor of the area, John Cunningham
• Under the supervision of Renee Roberge PEng of the EMS Dept. of HRM, extensive TV inspection of the trunk storm systems, and smoke testing were carried out. No sanitary laterals were connected to the storm systems draining into Maynard Lake.  It was very encouraging news and thank you HRM!
  
  
• Intervention of Craig Campbell PEng of the EMS Dept., HRM; June 18, 2002

• Maynard Lake Subcommittee for an experimental project- this committee has now disbanded due to total lack of cooperations from the Community Grants Program

• Our request for the Regional Council's support to name Maynard Lake Park/Beach as the Cunningham Park/Beach; September 07, 2004

World class Bacterial Source Tracking (BST) of the lead indicators, Bacteroides Prevotella species

BST results:

Essentially, the following report from the "The" world-class expert, Prof. Kate Field PhD of the Oregon State University on the BST based on the common anaerobic Bacteroides Prevotella species concludes that 50% of the filters were positive for one or both human markers; none of the filters were positive for the dog marker; and that all the 17 filters were positive for the non-specific fecal marker. It further states that in the obvious absence of farm animal impact, the most likely source is waterfowl since the non-specific fecal marker readily detects waterfowl fecal contamination.

For a background literature and associated synopsis on BST, see the report prepared by Applied Limnologist, Shalom M. Mandaville.

High recommendations from independant regulators on Prof. Field's methodology

Maynard Lake Subcommittee for an experimental project- this committee has now disbanded due to total lack of cooperation from the Community Grants Program although it was Renee Roberge PEng of the EMS Department who asked us to utilize scallop shells, alas!

One of the technologies applied, notwithstanding the varying E.coli sources, was the experimental methodology implemented in a class project elsewhere in year 2002 by Trottier, Beaton-Johnson, and Fares which has received acclaim from Director General, George Iwama PhD (pers. comm. April 17, 2003), and from Laura Brown PhD (pers. comm. May 09, 2003) of The National Research Council of Canada (NRCC), Halifax.

In addition, we have also been carrying out several educational programs for public stewardship.
