Abstract
Groundwater is a crucial natural resource in the state of Florida. since it supports to environmental, social, and economic aspects of the country. Groundwater will not be contaminated easily but it is difficult to restore once it is contaminated. Since its extensive usage in agricultural activities in the state of Florida, groundwater has degraded in recent years, resulting in many direct and indirect impacts, particularly nitrogen content in the form of nitrates using Geographical Information System (GIS) technology, the researchers investigated the effects of groundwater on Nitrogen (NO3) content in the study area by creating a spatial distribution of NO3 contamination, which was then analyzed using GIS, Kriging Interpolation, and the DRASTIC model to determine the susceptibility of groundwater to NO3 contamination. The final result depicts the model’s performance as vulnerability groups, which are based on natural breaks showing places that are more susceptible to nitrogen pollution. The map highlighted that the south zone of Florida was more vulnerable to nitrogen contamination, necessitating more careful wastewater disposal system planning.
Highlights
IntroductionThe importance of water in human life and culture cannot be overstated. Both groundwater and surface water play important roles in economic, social, health, recreational, and cultural activities, as well as in environmental and ecosystem preservation (Abdul Bari et al 2015, Tirkey et al 2013, Anornu et al 2012)
The main aim of this project is to create a thematic map for Florida that portrays the areas most susceptible to nitrogen pollution
The various layers were generated based on the above section using the databases listed in data sources and the Soil data viewer tool
Summary
The importance of water in human life and culture cannot be overstated. Both groundwater and surface water play important roles in economic, social, health, recreational, and cultural activities, as well as in environmental and ecosystem preservation (Abdul Bari et al 2015, Tirkey et al 2013, Anornu et al 2012). The most critical water resource on the planet is groundwater (Abdul Bari & Jamuna 2020) It is the sole source of water for drinking, agriculture, and industrial uses in many arid and semi-arid areas around the world (Tesoriero et al 1998). Several studies have used different approaches to determine the susceptibility of groundwater to nitrate pollution and other contaminants These techniques can be classified as follows: Overlay and Index Methods, Process-Based Methods, and Statistical Methods (Tesoriero et al 1998, Thirumalaivasan & Venugopal 2003), out of which the DRASTIC model, which comes under the Overlay and Index group, is one of the most commonly used groundwater vulnerability mapping methods. The ultimate goal of this research work is to use GIS-based modeling to create a model that can identify areas that are most susceptible to nitrogen pollution
