water quality modelling

[SavariaEnviro]

Hello,

Is there a computer program/model that can model chemical dilution and flow of a site?

I have a site with an industry that treats and stores wood in piles on their lot. In the past there has been monitoring on chemicals (chromated copper arsenate, creosote, PCP, and Alkaline copper quaternary) which are leached from the piles of treated wood to which I have the data as well precipitation for the specific periods. with this information, I am looking to model the concentration of the chemicals at the outflow of the site, is there a computer program out there that is able to do this, I was thinking HEC-RAS, has anyone out there used HEC-RAS for something similar?

Check out the EPA Storm Water Management Model (SWMM) and the Soil and Water Assessment Tool (SWAT); both are hydrological models with added capabilities to simulate nutrient and pollutant transport.

Out of the mire...a spectacle of perfection. #TheLotusConstruct

Thanks cadsync,
I will look into these models, however, i`m already familiar with using the steady flow analysis in HEC-RAS so if I could stick with HEC-RAS it would be great. therefor, my question becomes: does the water quality feature in HEC-RAS deal only with nutrients or can external chemicals be added?
