HPIM1221.JPGDuffield Associates is experienced in the use of the Nutrient Loading Assessment Protocol for estimating pre- and post-development pollutant contributions from non-point sources to determine whether TMDL reduction targets have been met.  Duffield Associates personnel have been trained by Watershed Assessment staff and have worked with those staff in holding training sessions for state and local land use planners, county land use staff and members of the private development community.  We have also worked directly for clients in using the protocol to assess the impacts from a number of development projects.
