ABSTRACT • Aim : The purpose of this study is to make a research on the effects of chemical wastes on groundwater and identify effects on human and the environment. • In this study , chemicals wastes in groundwater, pollution and possible solution methods are investigated and presented.

RESEARCH PROGRESS • CHEMICAL THREATS ON GROUNWATER AND THEIR EFFECTS • Natural Chemical Wastes • Synthetic Chemical Wastes • Industrial Chemical Wastes • Agricultural Chemical Wastes

NATURAL CHEMICAL WASTES Groundwater Minerals • Sodium , Calcium, Potasium, Chloride, Bicarbonate, sulfate Undrinkable • İf the mineral exceed 1.000 mg / liter Dangerous Minerals • Biological Organisms such as bacteria , protozoans , viruses Causes waterborne diseases

SYNTHETIC CHEMICAL WASTES Factory waste , domestic sewage , storage tanks produces synthetic Chemicals • hydrocarbon • complex polymers • gasoline and oil how is it mixing to the ground? • landfills • rain waters http://www.enviroblog.org/2008/10/whither-plastics-and-whither-humanity.html • improper drain

INDUSTRIAL CHEMICAL WASTES Mines, factories, refineries and electronics makers produces heavy metals • copper • lead • mercury • Man-made chlorinated solvents(trichloroethylene and perchloroethylene) Air pollution by industy • toxic gasses : nitrogen dioxide or sulfur dioxide seep into the ground http://wihresourcegroup.wordpress.com/2009/10

AGRICULTURAL CHEMICAL WASTES Industrial farming man-made agricultural chemicals herbicides, pesticides and antibiotics. • These wastes, with high levels of nitrogen, phosphorus and pathogens, can contaminate the local aquifer.

GROUNDWATER MANAGEMENT ‘’Protection of groundwater sources is becoming a more widespread global concern by the recent European Commission directive which focuses on preventing rather than cleaning up pollution’’(EC 2003).

Trends in groundwater use in USA billion (gal/day vs year) Groundwater is the water which is in underground surface together with rock formation Surface water is the water wh ich is in rivers, lakes, oceans Water Science for Schools(2000) http://ga.water.usgs.gov/edu/earthgwusetrend.html

CLEANING UP CONTAMINATED GROUNDWATER • Groundwater tends to move very slowly and with little turbulence, dilution, or mixing , so once contaminants reach groundwater and they form a concentrated plumethat flows along with groundwater.

CLEANING UP METHODS • Containing the contaminants to prevent them from migrating from their source; • Removing the contaminants from the aquifer; • Remediating the aquifer by either inactivating or detoxifying the contaminants while they are still in the aquifer; • Treating the groundwater at its point of use; and • Leaving the use of the aquifer and finding an alternative source of water.

REMOVAL METHODS Pump-and-treat method Air Sparging System

BIOREMEDIATION • Bioremediationis a treatment method which uses naturally accurring microorganisms to get rid of some contaminationsinto less toxic or non-toxic substances. • By adding nutrients or oxygen, this process can be recoveredand used to effectively clean up a contaminated aquifer. Advantages • Environmently friendly • Minimal disturbance • Comparatively inexpensive

TREATMENT Depending on the complexity of the aquifer and the types of contamination, some groundwater cannot be restored to a safe drinking quality. Under these circumstances, the only way to regain use of the aquifer is to treat the water at its point of use.

CONCLUSION • The study has stated that the types of chemicals on groundwater contamination. Then, how these chemicals affets on groundwater was shown.The substantial solutionsof groundwater contamination was investigated . The study has also shown that water rcycling was simple andessential solution to prevent groundwater pollution.

WATER RECYCLING IS ESSENTIAL !
