Watershed Watch Analyses
currently included in the URIWW program:
depth transparency) is determined weekly by program
volunteers using a Secchi disk and a view tube.
These easy to perform measurements can be used
to assess seasonal and/or long term trends in lake
water clarity and indicate the same trends in terms
of water quality and eutrophication.
is determined from samples which are collected,
processed and frozen biweekly by program volunteers.
These processed samples are analyzed for chlorophyll
content in URI Watershed Watch analytical laboratories.
These measurements can be used to assess nutrient
enrichment and eutrophication. They complement
the Secchi depth information.
determined biweekly by program volunteers using
field kits. The analysis is performed on water
samples collected from a depth of 1 meter above
the bottom of the lake or river. These measurements
can be used as an indicator of eutrophication and
the overall health of an aquatic ecosystem.
measured weekly at the surface, and biweekly at
depth by volunteers using thermometers.
and pH are
analyzed in the URI Watershed Watch laboratories
from water collection event samples. They are used
to monitor the acidification status of water bodies.
- Nutrients (total
and dissolved phosphorus,
ammonia, total and nitrate-nitrogen)
are analyzed in the URI Watershed Watch laboratories
from tri-season water collection samples. These parameters
are used to assess the water bodies degree of nutrient
enrichment, or eutrophication. These measurements complement
the Secchi depth and chlorophyll content measurements.
- Bacteria (enterococci
and fecal coliform in marine water) are analyzed in the
Watch laboratories from water samples collected in sterile
bottles. These analyses screen for suitability for recreational
water uses including shellfishing, and may indicate sewage
Quality Analyses performed by URI Watershed Watch primarily
provide information on:
The URI Watershed Watch program
incorporates procedures and protocols recommended and
approved by national organizations to ensure that monitoring
results accurately reflect the conditions of the sampled
water bodies. Results from laboratory staff and volunteers
are regularly checked against known standards and quality
control samples. State-of-the-art research grade instruments
are generally used, permitting high resolution and excellent
detection limits. Specific methods of analyses and limits
of detection are available upon request.
