About the Data

Water Quality Parameter

Explanation

E. Coli type of fecal coliform bacteria that comes from human and animal waste - the EPA water quality standard for E. coli bacteria is 394 colony forming units per 100 mL.
Nitrates runoff from fertilizer use, leaching from septic tanks, and erosion of natural deposits- can cause oxygen depletion
Phosphorus/Phosphates excess can cause depletion of dissolved oxygen and death and decay of vegetative and aquatic life
Turbidity measure of the cloudiness of water
pH measure of the acidic or alkaline nature of a solution - measures of 6-9 are acceptable levels
Dissolved Oxygen measure of the gaseous oxygen in solution - should be less than 110%

Data related to all of the water quality parameters listed below was not collected at all sites or in all years.
