MACROINVERTEBRATES
Results from DEP DWM’s 1998 benthic macroinvertebrate studies in the Nashua River Basin are presented in Appendix C Biological Assessment of Streams in the Nashua River Watershed From 1998 Data, author: Robert Nuzzo.

PERIPHYTON and PHYTOPLANKTON
Results from DEP DWM’s 1998 periphyton and phytoplankton sampling are presented in Appendix D of this report as a technical memorandum by Joan Beskenis entitled Nashua River 1998 Chlorophyll a, Phytoplankton and Periphyton Sampling.
FISH TOXICS
Fishes from Snows Millpond and Lake Whalom were analyzed for toxic contaminants in 1998 as part of a survey of the Nashua River Watershed. Results (MA DEP 1998b) are presented in Table B8. The goal of the sampling effort was to screen resident fishes for PCBs, organochlorine pesticides, and selected metals (As, Cd, Hg, Pb, and Se).
Table B8. 1998 DEP DWM fish toxics monitoring data for Snows Millpond, Fitchburg/Westminster and Lake Whalom, Lunenburg. Results (mg/kg wet wt.) are from composite samples of fillets with skin off.

Snows Millpond was sampled using gill nets and rod and reel on 2 October 1998. At Lake Whalom, electrofishing was conducted on 30 September 1998 and trotlines were set overnight and picked up on 1 October 1998. Where possible, fish selected for analysis (Table B8) represented species and sizes desired by the angling public for consumption, as well as from different feeding guilds (i.e., top level predator, invertivore, omnivore).
As detailed in Table B8 three species of fish, largemouth bass (Micropterus salmoides), yellow bullhead (Ameiurus natalis) and white sucker (Catostomus commersoni) were collected from Snows Millpond, and four species, largemouth bass, yellow perch (Perca flavescens), bluegill (Lepomis macrochirus), and yellow bullhead (Ameiurus natalis) were collected from Lake Whalom. Composite samples of each species were analyzed for metals (As, Cd, Pb, Hg and Se), PCBs, and organochlorine pesticides.
Table B8 lists species, length, and weight data for the individual fish as well as the analytical results. Cadmium, lead, and arsenic were below method detection limits (MDLs) in the edible fillets of all samples analyzed. Selenium was detected in all samples analyzed ranging from 0.24 to 0.47 mg/kg wet weight. Mercury in edible fillets ranged between 0.04 and 0.33 mg/kg wet weight at Snows Millpond and between 0.10 and 0.25 mg/kg wet weight at Lake Whalom.
Based on the results of the mercury analysis in fish tissue from these two waterbodies, (using a trigger level of 0.5 mg/kg wet weight Hg) DPH has determined that mercury does not pose a significant risk in either of these waters.
PCBs and pesticides were below detection in all samples analyzed.
LAKES
Lake synoptic survey results (MA DEP 1998c) are presented in Table B10
