May 2011: Nashua River not too clean

The rivers we monitor didn’t rate a good grade this month for cleanliness. Out of the 40 sites monitored in May, 20 did not meet the state standard for swimming or boating. This is likely due to erosion and runoff from rains in the previous week and possibly from overflows from the wastewater treatment plants.

On a really good note, after some pipe sampling we did in Fitchburg, the city tracked down a large leak that was getting to the river and is in the process of fixing. They snaked a video down the pipes to find it, good work DPW!

Thanks to Suzanna Black and our High School intern Valerie for doing a windshield survey of Sucker Brook in Pepperell to investigate some high bacteria counts. This data combined with our monthly monitoring will help understand what could be causing the spikes.
