Land use measures
Measures on land use that influence the groundwater quality 
in short and long term


Land measures or land use control activities
are to reduce the input of pollution into groundwater resources
and to develop planning and regulatory mechanisms to control
activities on the land that could contaminate an aquifer.
Land use regulations, land acquisition, and education
programs can play a key role in protecting groundwater.
Examples of land use control activities include the following:

- Land use plans which take into account groundwater vulnerability;

- Zoning ordinance and site plan review standards related
to aboveground secondary containment, interior floor
drains, and other topics;
- Purchase of land and/or conservation easements to provide
a wellhead protection buffer around municipal wellfields;
- Public education through public meetings, school-based
classroom programs, library displays, cable television
videos, public information flyers, and municipal newsletters.

Classical measures to decrease the input mainly of diffuse
pollution are reforestation of areas and conversion of
farmland to grazing land. Here and in new woodlands the nitrogen
index falls markedly in comparison to farmland.
