The current (2019) predicted groundwater quality layer for nitrates and phosphates was made by spatial interpolation of the current (2019) predicted groundwater 95th percentile nitrate and phosphate concentration for each of the scoped in sites. These values were estimates made using one of these statistical approaches based on the amount of data available, and range of years this data was across: - Weibull for the 2017-2019 data; a bootstrapped Theil – Sen using a 1.16 adjustment of the mean concentration for all data; a uniform value based on a 1.16 adjustment of the mean concentration of all data. The future (2031) predicted groundwater quality layer for nitrates and phosphates was made by spatial interpolation of the future (2031) predicted groundwater 95th percentile nitrate and phosphate concentration for each of the scoped in sites. These values were estimates made using one of these statistical approaches based on the amount of data available, and range of years this data was across: - Weibull for the 2017-2019 data followed by a bootstrapped Theil – Sen for all data; a bootstrapped Theil – Sen using a 1.16 adjustment of the mean concentration for all data; a uniform value based on a 1.16 adjustment of the mean concentration of all data.
