PURPOSES OF
OF WATER
WATER QUALITY
QUALITY TESTING
TESTING
• To determine impacts due to human activities (e.g.,
residential or industrial development, agricultural use)
• To determine impacts due to transbasin diversion systems
and possible related erosion
• To obtain baseline information to determine possible future
impacts due to coal bed methane development
