21	Considerations collected 2,368 samples since 1988 1,052 samples since 2002 will have five years data in 2006 district-wide information (forest) could begin trend analysis (trees) by sub-unit by individual well compare well trends within sub-unit need consistent sampling population if well not running go to next? ... return until running? sampling cost considerations
22	Considerations Does water quality correspond to water yield? quality changes v. depletion areas Manage by quality as well as quantity? priority areas of concern? e.g., map nitrate levels v. nitrate trends Help target technical assistance? other resources? other agencies?
