Water Quality

Weekly Water Sample Results


In accordance with NH RSA 485-A, Class B waters, those acceptable for fishing, swimming and other recreational purposes, shall not have greater than an average of 88 Escherichia coli (E-coli) per 100 milliliters of water.

When water sample results are greater than an average of 88 E-coli per 100 milliliters, the Manchester Health Department may close the area to swimming until the levels are acceptable. We have listed the current E-coli per 100 milliliter reading below the image of the Natural Bathing location.

Introduction 

The Division permits over 60 indoor and outdoor pools and spas annually. Each indoor pool and spa is inspected twice a year. Each outdoor pool is inspected upon opening each spring and at least once more during the summer season.  To help prevent such occurrences the Division hosts a Pool and Spa Operator’s educational course twice a year. Our Environmental Health Specialists are all Certified Pool Operators (CPO), the National Standard for the industry.

From our understanding of disease transmission, it is well known that contacting or ingesting contaminated water has been linked to diarrheal illnesses as well as ear, skin and other infections. In an effort to prevent disease, indoor pools and spas are inspected at least twice per year; outdoor pools are inspected prior to opening for the season then twice per season, and natural bathing areas once a month during the open season. If significant issues are found upon inspection the facility may be closed "on the spot".

The focus of these inspections is upon water quality and bather safety. In addition, weekly water samples are taken at natural bathing areas across the City. Bodies of water such as Crystal Lake, the Piscataquog and Merrimack Rivers and Long Pond are monitored to ensure that pathogenic bacteria do not pose a hazard to swimmers. The Division continues to work with other City, State and Federal agencies in the protection of these natural resources.

The Manchester Health Department inspects swimming and bathing facilities to determine compliance with rules promulgated by the NH Department of Environmental Services under authority of Chapter 485-A of the NH Revised Statues Annotated. Copies of the "New Hampshire Public Bathing Facility Rules" (Ws-1100)
are on file at the Manchester Health Department or are available from the NH Department of Environmental Services, 6 Hazen Drive, Concord, NH 03301 or go to NH Public Bathing Facility Rules for a copy.

An application to operate a public bathing place must be made prior to opening the bathing area and should be made on a form provided for this purpose. A facsimile of the application is provided it can be found in the forms section below.

Inspections are recorded on an inspection report of which a copy is left with the operator. If facilities are found to pose an immediate risk to the public, then the Environmental Health Specialist will order the owner or operator to close the facilities until such time as a reinspection finds conditions satisfactory.
