The document contains photos and information about water quality and pollution issues affecting the Catawba River watershed region. Over the past 20 years, non-point source pollution has increased by over 55% due to changes in land cover from development. Some of the specific water quality issues called out are excess nutrients causing eutrophication, low dissolved oxygen, acid rain, mercury, and fecal coliform bacteria from improper sewage treatment. Development increases the amount of polluted runoff entering waterways, carrying sediments, bacteria, metals, pesticides, fertilizers and petroleum.
