Acidity status of surface waters in massachusetts

, : Acidity status of surface waters in massachusetts. Water Air & Soil Pollution 63(3-4): 237-251

The Massachusetts Acid Rain Monitoring project surveyed 80.5% of the state's 5294 named water bodies between 1983 and 1985. PH and acid neutralizing capacity (ANC) were measured monthly the first 14 mo and semi-annually afterwards. Sample collection and analysis were performed by volunteers. The majority of surface waters in Massachusetts [USA] were found to be sensitive to possible long term acidification, with 63% exhibiting ANC less than 200 .mu.eq L-1 and 22% with ANC less than 40 .mu.eq L-1. Seasonal patterns in ANC were observed, the median ANC being 384 .mu.eq L-1 in summer/fall and 134 .mu.eq L-1 in winter/spring. Geographical differences were also found across the state: the streams and lakes with lowest pH and ANC were located in the southeastern and north-central parts of the state, while the most alkaline surface waters were found in the western-most part of the state, which is the only area of the state with significant limestone deposits.
