Water Testing Kit Water Temperature Dissolved oxygen Total solids (conductivity) Water Clarity Salinity – (freshwater.5 ppt., sea water 35 ppt.)

Water Testing pH – (acidic or basic) neutral to basic, east Texas 5.5 > 9.0 or < 5.0 Can affect organisms’ life cycle Rocks, soils, & minerals in a watershed Act as buffering material to keep pH levels stable

Water Quality How can human activity contribute to the pollution of ground water?

Water Quality How can human activity contribute to the pollution of ground water? Improper animal waste run-off Dumping of chemical from factories Rain washing motor oil from leaky cars (parking lots) Run off – fertilizer, pesticides, herbicides Garbage dumps

Sediments affect water clarity of surface water Decreases the passage of light through water

Landfill Pollutants in a landfill can slowly seep through the ground and contaminate groundwater

Runoff from Development Fertilizer Pesticides Herbicides Oil – leaky cars Animal waste Litter Covering over the Earth with pavement and or concrete reduces groundwater recharge zones

Land Development

Industrial wastes

Oil and gasoline

Agricultural wastes
