Escherichia coli (commonly abbreviated E. coli)-a Gram-negative, facultative anaerobic, rod-shapedbacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms).A level of 235 or over is considered unsafe to swim.
Alkalinity- the name given to the quantitative capacity of water to neutralize an acid. Measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfall or wastewater. The Guadalupe River has a high Alkalinity due to the lime stone formations it flows through. o-60 mg/L is soft, 61-180 mg/L hard, 181+ mg/L very hard.In some areas of Texas readings of 1000 to 2846 are common.
pH- a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline.Drinking water has to maintain a pH between 7.5 to 8
NTU- is a measure of turbidity.Turbidity-the cloudiness or haziness of a fluid caused by individual particles (suspended solids) that are generally invisible to the naked eye, similar to smoke in air.Drinking water has to be below .3
Dissolved Oxygen (DO)- is the amount of oxygen available in the water. If more oxygen is consumed than is produced, dissolved oxygen declines and some sensitive animals may move away, or die. DO levels fluctuate seasonally and over a 24 hour period. DO levels vary with water temperature and altitude. Cold water holds more oxygen than warm water.When DO levels fall below 3-5 mg/L, fish and other aquatic organisms may have difficulty successfully reproducing, feeding and surviving. Aquatic animals are most vulnerable to lower DO levels in the early morning on hot summer days when streams flows are low, water temperatures are high and aquatic plants have not been producing oxygen since sunset. The amount of oxygen consumed by microorganisms is increased in areas with woody debris: dead plants and animals, animal manure, effluents from waste water treatment plants, feed lots, failing septic tanks and urban storm runoff.
