Thesis to discuss:
With no natural streams supplying the lake and the watershed small, the predomin-ate hydraulic flow into the lake is from septic systems high in Phosphorus (P).
There are 800+ septic (Non-Point Source (NPS)) systems in the Candlewood Shores area contributing nutrients to the ground water. A high % of P discharges makes it to the lake.
- Estimate that using average P discharge per household.
- The approximate volume of the lake should be known.
- The lake level and flow out of the lake should be known.
- With this calculate the residence time and level of P by season.
- (Some P disappears in insoluble form in the bottom.)
Question: Does the ground attenuate most of the P? Or is the ground saturated with P, limiting the ability of the area to absorb P? Thus P into NPS systems is equal to P into the lake in this decade.
Objective: Gain insight into controversy. Are septic systems in high population areas surrounding Candlewood Lake contributing to the nutrient load? If so, at what level?
Proposed Approach: Set a plan to
- Test soil P levels near and away from NPS water drainages.
- Where septic systems are present, determine P gradient in soil to lake.
- Attempt to discover if there is a P gradient in the lake.
