*The ground soaks up water into its open spaces like a sponge.

* There, water is stored in underground geological water systems called aquifers.

* Groundwater does not occur as underground lakes or streams.


What Contaminates Ground Water?

* Household chemicals and cleaning products

* Excess nitrogen fertilizers, including manure and lawn fertilizers

* Industrial solvents and automotive fuels and chemicals

* Chemical spills from highway or railroad accidents, or spills from business or manufacturing sites

* Improperly applied pesticides or pesticide spills

* Above-ground storage tanks with petroleum products or chemicals

* Improperly installed or old domestic wells

* Poorly maintained septic systems

* Waste disposal sites or dumps

Arsenic In My Drinking Water?

*Arsenic is a semi-metal element in the periodic table. It is odorless and tasteless.

*Because it occurs naturally in the environment and as a by-product of some agricultural and industrial activities, it can enter drinking water through the ground or as runoff into surface water sources.

* Water is a universal solvent and suspends the arsenic in it easily.

Nitrates: One of most common contaminates...

* Can indicate the presence of bacteria or pesticides

* Nitrates in groundwater originates primarily from fertilizers, septic systems, and manure
