Peckenham et al. In 1999 and 2000, 44 stream sites at Acadia National Park were sampled for major ion chemistry and total mercury concentrations. The project was designed to determine whether mercury concentrations were related to watershed conditions in part determined by the fire of 1947, and streams were sampled under high and low flow conditions to determine whether relative discharge affected mercury. The project also provided a wealth of baseline mercury data for the Park and general water chemistry for sites that had been sampled in the early 1980s. Acadia Surface Waters - Baseline Data and Assessment
Kahl et al. During 1982-1984, aquatic chemistries of 18 lakes and ponds and 23 headwater streams in Acadia National Park were studied. The information from this study provided an assessment of potential impacts of acid deposition at Acadia, and an excellent baseline data set for sites that are revisited frequently for other research projects today.

Episodic Acidification at Acadia
Heath et al. Several streams in the Upper Hadlock Pond watershed were gauged and monitored in 1988-1989 for a study that estimated mass balances for the watershed, and determined mechanisms of episodic acidification for Acadia. Sea-salt effect acidification was implicated in several of the high discharge events. This work eventually led to the establishment of the paired watersheds at Acadia. References:

Acadia Lakes In 1995 and 1998, X lakes at Acadia National Park were sampled for major chemistry. The sampling complemented work done in 1982-1984 by Kahl et al., and provided the post-Clean Air Act Amendments status for the lakes sampled during the period of high acid rain, the early 1980s.
