Groundwater is found in the pores and cracks of underground sand, gravel, and rock deposits. The formation through which it slowly flows is called an aquifer. The top of the water-saturated zone is the water table, and water percolating down to it is called recharge. Nitrates can get into drinking water from many sources, but poor management practices can cause pesticide contamination. Pesticides can get into groundwater through agricultural, industrial, and homeowner uses as well as spills and improper disposal.
Contaminated water is difficult and expensive to manage once it becomes dispersed underground.
