Developed by: Svendsen Updated: U1-m1a-s17 Nonpoint source pollution: What is it? ehpnet1.niehs.nih.gov/docs/1994/ 102-9/focusnonpoint.JPG

Developed by: Svendsen Updated: U1-m1a-s18 NPS pollution: Characteristics  Occurs over extensive areas  Enters receiving water in a diffuse manner  Carried by water over land or through soil profile to receiving water  Difficult to trace to point of origin  Magnitude related to climatic events

Developed by: Svendsen Updated: U1-m1a-s19 NPS pollution: Sources of pollutants

Developed by: Svendsen Updated: U1-m1a-s20 NPS pollution: Impact from leading stressors

Developed by: Svendsen Updated: U1-m1a-s21 NPS pollution: Urban storm water  From streets, yards, buildings, and construction sites  Grease, salts, animal wastes, nutrients, sediments, lead, others akedata/lawnfertilizer/ studydesign.htm

Developed by: Svendsen Updated: U1-m1a-s22 NPS pollution  Agricultural  Nutrients, sediment, pesticides, herbicides p/Graphics4/$file/spraying.gif

Developed by: Svendsen Updated: U1-m1a-s23 NPS pollution  Forestry / Logging  Sediments  Pesticides logged es/connie200x150.jpg

Developed by: Svendsen Updated: U1-m1a-s24 NPS pollution  Mining  Sediments  Drainage waters with low pH  Heavy metals and other hazardous mineral

Developed by: Svendsen Updated: U1-m1a-s29 How Do We Know if We Are Successful?

Developed by: Svendsen Updated: U1-m1a-s30 Monitoring and Assesment

Developed by: Svendsen Updated: U1-m1a-s31 Beneficial uses:  Water quality for the beneficial uses can be degraded by human actions or natural events  The US Environmental Protection Agency is a major federal agency responsible for monitoring and assessing water quality

Developed by: Svendsen Updated: U1-m1a-s32 Beneficial uses: Monitoring program questions  What is the overall quality of waters in the State?  To what extent is water quality changing over time?  What are the problem areas and areas needing protection?  The State must identify impaired waters.  The State should also identify waters that are currently of high quality and should be protected from degradation  What level of protection is needed?  How effective are clean water projects and programs?

Developed by: Svendsen Updated: U1-m1a-s33 Beneficial uses: Five levels of water use 1. Fully supporting overall use  All designated beneficial uses are fully supported 2. Threatened overall use  One or more designated beneficial uses are threatened and the remaining uses are fully supported 3. Partially supporting overall use  One or more designated beneficial uses are partially supported and the remaining uses are fully supported

Developed by: Svendsen Updated: U1-m1a-s34 Beneficial uses: Five levels of water use 4. Not supporting overall use  One or more designated beneficial uses are not supported 5. Not attainable  The State has performed a use-attainability study and documented that use support of one or more designated beneficial uses is not achievable due to natural conditions or human activity that cannot be reversed without imposing widespread economic and social impacts

Developed by: Svendsen Updated: U1-m1a-s35 Water quality degradation: River use support

Developed by: Svendsen Updated: U1-m1a-s36 Water quality: Assessments problems  Not all bodies of water are assessed  Only a small percentage per year  Supposedly all within a 5 to 10 year window

Developed by: Svendsen Updated: U1-m1a-s37 Water quality: Assessments problems  Intermittent and small tributaries are either not assessed or are very infrequently measured  States tend to focus on known problems  Random surveys are rare  States have varying standards  Concentration on 2 of 6 use supports  Fish advisories not included

Developed by: Svendsen Updated: U1-m1a-s38 What would You Assess?  What data would you want?

Developed by: Svendsen Updated: U1-m1a-s39 Can You Put Your Data in Categories?

Developed by: Svendsen Updated: U1-m1a-s40 Proposed Categories  Physical  Chemical  Biological

Developed by: Svendsen Updated: U1-m1a-s41 Are These Independent Variables?  How might they relate…if they do?

Developed by: Svendsen Updated: U1-m1a-s42 Building Your Stream Model  Emphasize Relationships  Visualize Your Stream  The memory map

Developed by: Svendsen Updated: U1-m1a-s43  Four dimensions:  Longitudinal  Lateral  Vertical  Time Lotic systems The four dimensions of a lotic system

Developed by: Svendsen Updated: U1-m1a-s44  The shape, size and content of a river are constantly changing, forming a close and mutual interdependence between the river and the land it traverses. Variation in time and space
