HOW IS GROUNDWATER CONTAMINATED?
Septic Systems: Septic tanks that are above groundwater aquifers may fail to break down contaminants due to: • Improper construction, design or location • Too many septic systems in one area • Inadequate maintenance (Septic tanks should be pumped periodically to prevent overloading) • Toxic materials being released in the septic system by pouring paints, solvents and other potential contaminants down the drain or toilet. These may compromise the life of microbial organisms that break down contaminants. • Storm drains: The drains you find on streets are called “storm drains.” Water from rainfall and snow can wash contaminants off the surfaces of streets and sidewalks. These substances may be so harsh that normal microbial degradation cannot occur before reaching groundwater supplies below. • Household Actions: Simple acts around the house can affect the quality of our drinking water. Harsh chemicals that are poured down the drain, down the toilet, or on the ground can contaminate. In ad
