Cape Cod Times: State Proposes new limits on toxic PFAS chemicals

Tougher standards would apply to drinking water, contaminated site cleanups.

Wicked Local: APCC: Herring counts show mixed results

An analysis by the Association to Preserve Cape Cod of the 2019 volunteer spring herring counts show the results to be a mixed bag containing both good and bad news.

My Title 5 septic system is working fine. What’s the problem?

Answer:  Title 5 septic systems are designed to protect public health by removing solids and bacteria from sewage. The design does not remove nitrogen and phosphorus, which are the nutrients that are causing poor water quality in our ponds and embayments.

Solids are collected in the septic tank and the remaining liquid flows into the leaching field which soaks into the ground, ultimately reaching groundwater. This liquid contains high concentrations of dissolved nitrogen and some phosphorus, among other things put down the drain.

The nitrogen and phosphorus-rich liquid percolates down through soil to the groundwater that flows into our ponds and embayments. On Cape Cod, septic systems are the major source of excess nutrients contributing to poor water quality, followed by fertilizers and stormwater runoff.

Cape Cod Times: Toxic algae bloom in Mashpee spreading to Santuit River

A section of the Santuit River that zigzags behind houses in a wooded area in Mashpee has turned bright green, causing an uproar among residents.

“I think at the end of the day, it’s going to take a public uprising about water quality, whether it’s Santuit (Pond)or other places as well, to create the political will necessary for towns to take the hard steps needed to solve these problems,” said Andrew Gottlieb, a Mashpee selectman who is also executive director of the Association to Preserve Cape Cod.

Cyanobacteria Blooms in Santuit Pond

Santuit Pond

Isn’t this a beautiful drone shot of the fall colors looking down onto Santuit Pond in Masphee? But take a closer look! A cyanobacteria bloom clouds the water and has been making the water murky for several weeks.

Santuit Pond

While cyanobacteria are a part of a pond ecosystem, these thick blooms that can appear as pea soup, snotty scum and look like someone spilled blue-green paint on the surface of the water signify a problem. Certain cyanobacteria always indicate toxic conditions and pose health problems for wildlife, pets and people.

Santuit Pond

Avoid contact and certainly don’t let your dog swim here. If your dog does come in contact with the pond scum, wash thoroughly with clean water and call your vet immediately if your dog experiences vomiting, drooling, or other illness. Town of Mashpee has posted a cyanobacteria advisory.

Santuit Pond

We saw several blooms this past summer because warm temperatures also help stimulate growth. Daily temperatures in October were mostly all above average, so apparently we’re not out of the woods yet and it’s November!
