As part of the larger Housatonic River Project (see Remediation Solutions section for more information), Bluestone staff have directed and performed extensive biological studies for inclusion into the ecological risk assessment including the following:
Our Team has also been involved with innovative statistical approaches for assessing ecological risk, including Monte Carlo analysis, probability bounds analysis and geostatistical analysis (e.g., Thiessen polygons, inverse distance weighting, and nearest neighbor analysis) to determine exposure concentrations.
