How are nutrients in water created?

Water can often contain nitrogen or phosphorous (nutrients) which create algae to grow and removes oxygen.

Some republicans in my state house and senate are trying to prohibit regulations of nutrients. I was wondering what businesses this would affect and how the nutrients are created.

    The nitrogen and phosphorous that get into the water come largely from fertilizers that are carried into rivers, lakes, streams, etc via stormwater runoff. As you said in your question, this can cause abnormal algae growth, oxygen deficiencies, and other impacts to bodies of water and the habitat they provide.

    Many municipalities (on the city/county level) have requirements in their Code or Zoning Ordinances that require certain types and quantities of landscaping and green areas on sites that are developed. Plants have a great ability to remove many of these potentially harmful nutrients from the stormwater as it is absorbed by their roots. This prevents it from entering the water table as well. They also have ways to quantify the amount of pollutant removal that a stormwater management method can accomplish per site.

    Regulating the use of fertilizers and certain specific nutrients, as well as requiring proposed developments to incorporate stormwater management methods that reduce pollutant loads simply puts more restrictions on development than some of these representatives want to abide by. This will affect any new development--whether it's a residential subdivision or commercial use. They may want to prohibit these regulations because they think it will stifle growth and development. In economic times like these, many localities want to welcome as much new development as they can in order to generate tax revenue.

    Regulating these nutrients will also have a huge effect on the agriculture industry!
