Groundwater Contamination
INTRODUCTION In the southern United States, chemicals are an integral part of the management of bare-root nurseries. The rationale for using chemicals is based on economics as they can reduce hand labor, improve the use of valuable seed, and increase seedling performance. The cost of all chemicals associated with loblolly pine seedling production averages less than 0.2 cent per seedling. The co...

متن کاملThe Property Value Impacts of Groundwater Contamination:
There are few studies examining the impacts of groundwater quality on residential property values. Using a unique dataset of groundwater well tests, we link residential transactions to home-specific contamination levels and undertake a hedonic analysis of homes in Lake County, Florida; where groundwater pollution concerns stem primarily from agricultural runoff. We find that testing and contami...
متن کاملContamination and restoration of groundwater aquifers.
Humans are exposed to chemicals in contaminated groundwaters that are used as sources of drinking water. Chemicals contaminate groundwater resources as a result of waste disposal methods for toxic chemicals, overuse of agricultural chemicals, and leakage of chemicals into the subsurface from buried tanks used to hold fluid chemicals and fuels. In the process, both the solid portions of the subs...
متن کاملArsenic contamination of groundwater: a Bangladesh survey
A series of surveys has been conducted in two rural communities of northeastern Bangladesh where a nationwide contamination of groundwater by geologically originated arsenic has been reported. The arsenic concentrations of the tubewell water (twAs), which has been used for drinking and cooking, varied considerably within the small geographical area, as did the urinary arsenic concentrations (uA...
