Nutrient Mitigation

Reduce the phosphorus and nitrogen that fuel algae blooms, and keep them out for the long term.

Assessing nutrient levels and sources

Identifying nutrient sources

Effective nutrient management begins with a comprehensive water quality assessment to determine the levels of phosphorus, nitrogen, and other contributing factors. Through water sampling, sediment analysis, and watershed evaluations, we identify the main nutrient sources and quantify the load stored in the sediments.

Internal loading happens when nutrients stored in lake sediments are released back into the water, common in older or nutrient rich lakes where decades of organic buildup create a constant source of phosphorus and nitrogen.

External loading comes from wastewater, fertilizer runoff, stormwater, and organic debris from surrounding land. Managing these sources limits future buildup.

Nutrient reduction strategies

Reducing internal and external loading

One of the most affordable and effective ways to reduce internal loading is phosphorus inactivation, a treatment that uses products such as lanthanum modified bentonite clay, iron and calcium to bind phosphorus in the water and sediment so less is left to feed algae.

Where organic buildup is the main driver, our biological muck treatment digests organic muck and leaves sand behind, restoring depth and clarity. It works without aeration. We also use floating islands as natural nutrient filters.

Long term monitoring

Tracking nutrient trends over time

Nutrient management takes ongoing monitoring and adaptive strategies. Seasonal water quality testing tracks nutrient levels so the plan can be adjusted before problems return. By addressing the root causes of nutrient pollution, we build healthier, more resilient waterbodies and reduce the need for frequent algae and weed treatments, saving time and money.
