TASK 2 COUNTY ACTION PLANS Create action plans

TASK 2: COUNTY ACTION PLANS • Create action plans to solve 4 problems in Greenville County. • • 1. High nitrate levels in drinking water aquifer 2. Surface Water eutrophication 3. Spring Flooding in the town 4. Invasive Species ( Silver jumping carp ) need to be kept out of the lake

TASK 2: Problem #1 High Nitrate Levels in city well water

High Nitrate Levels in Drinking Water … data from the U. S. Geologic Service

EPA's drinking water regulations for nitrate • 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur. • The maximum safe level for nitrate is 10 mg / L or 10 ppm. • EPA has set this level of protection based on the best available science to prevent potential health problems.

Nitrate's health effects? NO 3 • Infants below six months who drink water containing too much could become seriously ill and, if untreated, may die. • Symptoms include shortness of breath and blue baby syndrome. ( lack of oxygen in blood )

TASK 2: Problem 2: SURFACE WATER QUALITY: The green River and Dragonfly Lake are undergoing mild eutrophication. Too many nutrients are reaching the lake … causing algae blooms

TASK 2: Problem 3. Spring Flooding

We need to know the Foodplain of a River before deciding where to build !

Will you allow homes to be built in the Floodplain?

TASK 2: PROBLEM 4: INVASIVE SPECIES: Silver carp ( top ) Bighead Carp ( bottom )

Invaders: Silver Carp jump in response to boat motors

G ill Rakers of invasive Bighead Carp Bony for catching aquatic insects

Silver Carp Gill Rakers. Fused and Sponge-like for filtering plankton

Invasive Species: Northern Snakehead

Snakehead can “walk” and survive up to 3 days out of water.

Young snakehead could be sold as a minnow Don’t dump minnows!
