High Sediment Levels at Town Pond
Nutrient Remediation Case Study

Location and Acreage:
Barnstable, MA | 120-Acres

Project Timeframe: 
2015

Project Managers:
Dominic Meringolo, Senior Environmental Engineer and Regional Leader

Key Staff:
Matt Salem, Permit Coordinator and GIS Specialist
Ed Taube, Mechanical Specialist II

Site Description:
This 120-acre pond was previously treated with alum in 1995, which provided nearly 20 years of successful control. In 2013 and 2014, conditions started to deteriorate again and based on the success with alum at other ponds in Barnstable, the Town quickly set up funding to treat the lake again.

Scope of Work:
Alum Treatment

Project Description:
SOLitude worked with Water Resource Services to conduct monitoring and treatment of this pond in June of 2015.  The lake responded well to the treatment.  It is believed that phosphorus from deeper in the sediments migrated upwards since the treatment in 2015, which resulted in the deterioration. Additional sediment samples were collected in 2015 to further assess this phenomenon.
