Stop the Algae Monster! Excessive Nutrients are Harmful

Leaf litter accounts for 56% of phosphorous in urban stormwater.

The amount of phosphorous in the avg. year of lawn clippings can produce 100 lbs of algae.

1 lb of fertilizer over-application can equate to 34.2 lbs. of excess algae growth in waterways.

100,000+ miles of rivers and streams are polluted with excess nutrients.

Excess nutrients in our waters promote algae growth and can be harmful to pets and humans.

This also leaves an unpleasant odor as it often results in the death of aquatic life.
