Water Quality

No water no life. No blue, no green.
— Sylvia Earle

LSPA is dedicated to water quality and has been since its founding in 1898, when the leading issues were sawdust and trash in the lake and the level of the lake water. In the 1950’s LSPA collected water samples and tested for E. coli to ensure that Lake Sunapee met the New Hampshire Class A (drinking water quality) standards.

In the 1980s LSPA established water sampling protocols that continue today:

  • LSPA volunteer water quality monitors take regular water samples from Lake Sunapee at cove sites and tributary streams.
  • LSPA staff take routine in-lake measurements at four deep basin sites in Lake Sunapee.
  • All water samples are analyzed in LSPA’s Water Quality Laboratory at Colby-Sawyer College.

The LSPA Lab at Colby-Sawyer College also processes water samples for about twenty five area lakes as part of the statewide Volunteer Lake Assessment Program (VLAP). The NH Department of Environmental Services provides an annual water quality report based on its analysis of the VLAP data.
