Case Study

Chloride Reduction Study – Honey Lake

Pollutant loading calculations supported by hydrological analyses were used to estimate and reduce chloride pollutant loading into Honey Lake, a valuable recreational lake with a 1,296 acre watershed area. Engineering Services included Chloride Loading Calculations, GIS Mapping, and a Narrative Report. Prior to the Study, chloride levels were increasing at a rate of 8% per year. Based on monitoring, chloride levels were potentially toxic to juvenile fish, algae, and terrestrial plants. Sources of chloride were identified, and prescribed recommendations were provided to reduce chloride loading into the lake. State-of-the-art road de-icing practices were incorporated into the findings and recommendations. Cost estimates for modifications to the Township de-icing strategy were prepared.
