New testing for July will be done starting this week to see if the levels are moving in areas of Lake Hopatcong.
Promising Update on Phoslock Treatment in Landing:
In June to prevent HABs in New Jersey’s largest lake, a clay-based nutrient inactivating technology called Phoslock as applied in the southern end of the lake called Landing Channel occurred in June. The results have been promising with a decline in both phosphorus and algae. They will continue to monitor the area monthly.
More Biochar Installations Scheduled:
The first Biochar installations that started early in July will be continued this month, with the following areas targeted (Duck Pond in Roxbury, Memorial Pond in Mount Arlington and in two MTDs in Jefferson Township.
Ashley Cove targeted for GreenClean & Phoslock Treatment:
Starting this month, the Ashley Cove area will undergo a GreenClean treatment to remove the Mat Algae to get the area ready for the Phoslock Treatment.
Additionally, two Aeration projects and the floating wetlands is still awaiting pre-payment from the DEP. Princeton Hydro also conducted water samples where the weed harvester flipped as several of the Hopatcong Police Officers that attempted the rescue felt sick afterward.
