Lake Katharine History
This person built Lake Katharine in the early 20th century for recreational boating and swimming.
Who is Katharine Smith Reynolds?
This microbiological contaminant is found in human and animal intestines and can pose health risks in Lake Katharine.
What is E. Coli?
This type of bacteria serves as an indicator for potential pathogenic contamination in water.
What is a coliform bacteria?
This natural filtration method involves installing plants to remove contaminants from water.
What is biofilters (AKA wetland plants)?
This media was the best at removing E. Coli and lead from water samples.
What is sand?
This environmental issue caused sediment buildup and bank erosion in Lake Katharine.
What is erosion?
This toxic chemical contaminant can cause cognitive issues in children and high blood pressure in adults.
What is lead?
This instrument was used to measure turbidity levels in NTU.
What is a turbidity meter?
To prevent further erosion and sediment buildup, this type of barrier or reforestation method can be used.
What is a erosion control?
This media performed the worst in removing E. Coli from the lake.
What is GAC?
The contamination of Lake Katharine is a concern due to this type of infrastructure running through it.
What is a sewage pipeline?
The cloudiness of water caused by runoff, microorganisms, and organic material is measured as this.
What is turbidity?
The Quanti-Tray system used this type of light to indicate the presence of E. Coli.
What is UV light?
This practice involves creating physical barriers or planting vegetation to reduce the impact of water runoff and erosion.
What is erosion control?
This media had the highest efficiency in improving turbidity.
What is GAC?
This artificial lake is approximately this many acres in size.
What is 16 acres?
The lack of this type of aquatic organism in Lake Katharine may indicate lead contamination affecting reproduction.
What are fish?
This protocol was followed to test for lead concentration in water samples.
What is the Hach 850 protocol?
The law was used to compute the hydraulic capacity of the proposed filtration design.
What is Darcy's Law?
This media had little to not effect on water sample health.
What is gravel?
Due to pollution and sediment buildup, Lake Katharine has transitioned into this type of ecosystem.
What is a wetland?
Fecal contamination from this semi-aquatic rodent is a risk factor in the lake.
What is a beaver?
This device was used to determine lead concentration levels in mL/L.
What is a spectrophotometer?
The proposed filtration design measures this length and width.
What is a 2.5m by 2.5m?
The filtration design was validated because its hydraulic capacity exceeded this many gallons per day.
What is 32,000 gallons per day?
