    1. Mitigation of Pollution in Nursery Runoff J.N. Kabashima, Darren Haver, Jay Gan, and L. Wu

    2. Mitigating Pollutants in Nursery Runoff Water Proactive Participate in the process Get involved individually and as part of an industry group or association. Have data before you need it. Help develop solutions and regulations. Identify and seek sources of information and expertise. Reactive Try to figure out how to comply with regulations and or litigation.

    3. Mitigating Pollutants in Nursery Runoff Water Conduct a Self-Assessment Runoff and NPS Self-Assessment http://cesandiego.ucdavis.edu/Clean%5FWater/ Identify Management options Management Options for NPS Pollution http://ucce.ucdavis.edu/files/filelibrary/2017/10391.pdf Document Efforts Water Quality Record Keeping http://ucce.ucdavis.edu/files/filelibrary/2017/8453.PDF
