Addendum No. 2 Environmental Study Report Problem Identification Statement

2.6 Summary • Revised Problem Identification Statement

By way of this addendum, the original Problem Identification Statement of the original ESR has been reviewed as per the previous sections. For the most part, this addendum echos the original Problem Identification Statement. However, the requests received for Part 2 Orders expressed a number of concerns with the original Problem Identification Statement, as follows:

a) Questions and concerns were raised regarding the original 1995 water sampling program and as the water sampling program has not been repeated, a valid and current database is not available.

b) The Part 2 Order Registrants wished to stress that outside of the core area of Sauble Beach, the number of samples that contained adverse water quality for microbiological parameters was relatively low. Their analysis of the data would indicate that in the non-core area, potentially only 4% of water samples indicated microbiological contamination.

We conclude by indicating that there are many areas throughout Sauble Beach (and Hepworth) where lots are undersized for private wells and septic systems. In the case of Sauble Beach, microbiological water quality is relatively good considering the abundance of small lots, high utilization of the shallow aquifer during the summer period and the reliance, to a large degree, on shallow sand point wells with minimal protective overburden.

This addendum report concurs that lack of a database since 1995 and 1996 makes it difficult to determine if problems are getting better or worse in the core and non-core areas of Sauble Beach. Long-term water sampling programs from 1969, 1975 and 1980 (Table 2.3 on page 2-6 of Appendix A) would indicate that current raw water supplies may not be worse than what they were in these earlier years.

One factor that has not been carefully evaluated is the long-term trend in Sauble Beach for permanent occupancy versus temporary seasonal occupancy. If there is a long-term trend toward permanent occupancy of homes and cottages in Sauble Beach (with conversion of dwellings from seasonal to year-round residences as part of this process), there would be a reasonable expectation that the impacts on the shallow groundwater would worsen in terms of quality degradation.

This addendum proposes a wastewater collection and treatment system for only the core area of Sauble Beach. Similarly, this addendum proposes a water system for the same area, as a second priority, if sufficient funds are available. Similarly, no municipal water or sewage system is proposed at this time for Hepworth, in part due to lack of community support in Hepworth.

The Problem Identification statement with this Addendum is relatively unchanged for the Sauble Beach and Hepworth settings compared to the original ESR. Water supplies from sand point wells in Sauble Beach appear to be at risk from undersized lots (leading to minimal separation distances between sand points and septic systems) and the fact that the sand geology offers no significant overburden protection of the shallow groundwater supply. In addition to the microbiological risk that septic systems in Sauble Beach may pose, the aesthetic and non-aesthetic quality of the water is also relatively poor, and many home owners/cottagers utilize bottled water or in-home conditioning or treatment systems at this time.

For Hepworth, the quality of the drilled wells is also relatively poor, and there is minimal overburden protection of such wells. In many cases, there is likely inadequate separation distance between septic systems and private water supplies, and as noted in this Problem Identification statement, the age of many septic systems in Hepworth (and Sauble Beach) is fairly old and will continue to age.

Notwithstanding the above, the relatively seasonal nature of the current Sauble Beach community would appear to indicate that municipal servicing for the core area only at this time is desirable. However vigilance of the non-serviced areas must be practised over time, and the municipality is encouraged to conduct regular water quality surveys (every 5 years would be recommended). Also, a mandatory septic tank pump out bylaw to minimize the risk of septic pollution of private water supplies should be considered. The same protocol would also be recommended for Hepworth, as long as Hepworth remains without communal water and sewage systems.
