Water Quality

Between May and September, L.P.P.O.A contracts with Garden State Laboratories for weekly chemical and bacterial sampling and analysis, as required by New Jersey Department of Health Recreational Bathing Regulations (N.J.A.C. 8:26). The laboratory takes two weekly samples from all bathing areas. The results are reported weekly to L.P.P.O.A Management and Parsippany Township Health & Safety department.

Water Treatment

Between the months of May and September, Aquatic Technologies, Inc. performs regular monitoring and treatment of the lake, every 10 days. A pre-season treatment is done in early May. The lake is treated with Sonar, which is a systemic herbicide. This is a slow release approach which kills the rooted nuisance vegetation that is specific to our lake.  All of the services are conducted by licensed and trained aquatic biologists who use lake management techniques which improve the aesthetics, natural resources, water quality, and ecological balance of Lake Parsippany.


The L.P.P.O.A is committed to recycling and the benefits it will bring to future generations. Please ensure all empty bottles and cans are placed into the recycling bins that are situated throughout the beach area.

How You Can Help

Your everyday activities can affect water quality. Help reduce the amount of pollution that flows into our waterways by following the tips below.

  • Pick up after your pet. Properly dispose of pet waste into the trash or toilet. 

Animal waste contains coliform bacteria, which is harmful to our health and, when washed into swimming waters, can result in beach closings. 

Carry a plastic bag to pick up the waste when you walk your pet. Nuisance laws prohibit you from allowing your pet's waste to remain on private or public land. 

  • Reduce pesticide use, especially products like weed and feed. Using a lake-friendly, phosphorus-free lawn fertilizer will help protect the Lake and will not compromise your lawn’s appearance.

The three numbers in fertilizer bags show the N-P-K nutrient analysis. The middle number is the phosphate (phosphorus) content. A "zero" in the middle means it is phosphorus-free. 

  • Please Do Not feed the waterfowl.  It's the Law!

A lone goose can produce up to 1.5 pounds of droppings each day, and this influx of fecal matter can contribute to the spread of water-borne disease and harmful algal blooms. 

Feeding the waterfowl can be dangerous to the birds and hazardous to the township's ecology. Maximum fine $1000.00. ORD.#95.5
