There are several common forms of nitrogen including nitrite, nitrate, and ammonia. Nitrate is a form of nitrogen easily absorbed and used by plants and is a byproduct of the oxidation of ammonia. Phosphate usually occurs in low concentrations in water and plant growth in fresh water is limited by the amount of phosphate present in the water.       

On-site Systems – An individual system for treating wastewater, commonly called a septic system.

Open Space and Recreation Plan – A short and/or long term plan compiled by a community identifying current open space and parklands with a blue print for future acquisitions, changes and enhancements based on an assessment of community needs, habitat and sensitive resources.
