Groundwater Hydrology

Karis Heidebrecht

Page 14: Unit 8  Global Water Resources

Definition of Groundwater HydrologyThe study of the occurrence, circulation, distribution, and properties of any liquid water residing beneath the surface of the earth.

Page 15: Unit 8  Global Water Resources

Groundwater Hydrology● focuses on the distribution and movement of

water beneath the earth's surface.● is important for use in water supply and

irrigation.● helps farmers, rural homeowners, industrial

water supply leaders, well drillers and others learn about the development, occurrence, and conservation of groundwater.

Lead is a material plumbers use when

making water service lines

Page 48: Unit 8  Global Water Resources

The study found that women living in communities in which many homes had more than 10 micrograms of lead per liter of drinking water were more likely to have a child with neuraltube defects. Overall, the risk of such birth defects increased 25% for every 10% increase in lead level.

Congress enacted the Reduction of Lead in Drinking Water Act on January 4, 2011

To amend Section 1417 of the Safe Drinking Water Act (SDWA) regarding the use and introduction into commerce of lead pipes, plumbing fittings or fixtures, solder and flux.

The Act established a prospective effective date of January 4, 2014, which provided a three year timeframe for affected parties to transition to the new requirements.

What is this so-called “Stormwater?”

Definition~ Surface water in abnormal quantity resulting from heavy falls of rain or snow.

Page 53: Unit 8  Global Water Resources

Are they connected to Storm Drains?

YES! Storm Drains collect all of the fresh water after storms!

No... not always.....

“As the runoff flows over the land or impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality if the runoff is discharged untreated”. (U.S.E.P.A, 2012)

Page 56: Unit 8  Global Water Resources

How can it become clean?➔ The National Pollutant Discharge Elimination System (NPDES) Stormwater

Program regulates stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities, and industrial activities.

➔ This permitting mechanism is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters such as streams, rivers, lakes or coastal waters.
