PLAN OF DEVELOPMENT
According to the 2001 Brookfield Plan of Conservation and Development “Brookfield needs a coordinated overall public water supply system since the current system in Brookfield is poorly configured to meet community needs. The key water supply issue is the lack of an overall water system in the community and the dispersed nature of water supply providers. Water quality is also a continuing issue.”

BROOKFIELD, CT
WATER SUPPLY AQUIFERS
Each of the ten municipal plans of conservation and development has policies towards aquifers and water supply watersheds. Brookfield's and the other nine have been copied and placed into one regional file to facilitate comparisons.

An early regional leader in protecting groundwater, by late 1977 Brookfield had completed a report entitled "Natural Resource Considerations for Land Use Planning and Zoning, General Purpose Zone, Brookfield, CT." A 1980 Town commissioned report on the Gallows Hill aquifer followed.

Regional research in 1980 for Brookfield focused in the northern, or Gallows Hill Aquifer. At first protection was accomplished by adding regulatory text to each separate zoning district.

Then in 1987 the protection zone boundary created by HVCEO for the Gallows Hill Aquifer and an additional boundary created by Brookfield for the southern or Still River Middle Aquifer were made part of the local regulations.

1) Still River Middle Aquifer: The Still River Middle Aquifer, occupying much of central Brookfield. Entering from Danbury to the south, it extends northerly along the north flowing Still River and ends after crossing Silvermine Road. This resource includes an area of 1260 acres of saturated thickness of ten feet or greater.

2) Gallows Hill Aquifer: Then continuing northerly up the Still River Valley, beginning near the confluence of Limekiln Brook with the Still River, the Gallows Hill Aquifer is found. It continues north and crosses the municipal boundary into neighboring New Milford.

3) Pond Brook Aquifer: In the southeast corner of Brookfield is an arm of the Pond Brook Aquifer. This extends along the railroad right of way into Newtown where the remainder of the aquifer is located. This resource includes an area of 500 acres of saturated thickness of ten feet or greater.

WATER SUPPLY WATERSHED
1) Candlewood Lake Watershed: Water resource planning in Brookfield should make note of the fact that the Candlewood Lake Watershed may be a future water supply source for Danbury..

The reason is that if it is ever used by Danbury for water supply purposes (and possibly then thru Danbury to Brookfield or other towns), then the extreme western portions of the Town draining to Candlewood Lake will be regulated by CT DEP and CT DPH as a water supply watershed.

CONNECTIONS TO DANBURY
Water Main Connections to Danbury: As shown in this 2006 study, there are potential interconnections for Southern Brookfield and also to reach New Milford thru Brookfield.

CT DEP CLASSIFICATION
OF STREAMS IN BROOKFIELD
The Connecticut Department of Environmental Protection (CT DEP) has developed water quality standards in conjunction with the principles of the federal Clean Water Act.

As a result each stream or water body in the Region has two classifications, one for existing use, and one for ultimate future use, written in a existing/future format such as "B/A" or "A/AA". The highest standards are reserved of existing and potential water supply areas, which are AA.

The DEP seeks to bring every water body in the State to a minimum classification of "B" or better, which would not be suitable for human consumption without treatment, but could be suitable for recreational use, fish and wildlife habitat, agricultural and industrial supply, and other legitimate uses.

There is a non degradation policy such that stream now AA or A cannot be reduced to B to allow discharges from industries or treatment plants. The classification system and application to Brookfield is summarized below:

Class AA: Designated uses are existing or proposed drinking water supply, fish and wildlife habitat, some recreational use, agricultural and industrial supply. Discharges severely restricted.

Class A: Designated uses is potential drinking water supply; fish and wildlife habitat; recreational use; agricultural and industrial supply and other legitimate uses including navigation. Discharges severely restricted. No reclassification of A or AA allowed down to B.

Class B: Designated uses are varied and include discharges from industrial and municipal wastewater treatment facilities providing Best Available Treatment and Best Management Practices are applied. All water bodies must eventually reach the minimum standards of the B classification.

Classes C and D: Indicates unacceptable quality, the goal is Class B or Class A and DEP will issue orders to require improvement.

1. Candlewood Lake due to wastewater pumped up from the Housatonic River: B/B.

2. Housatonic River forming eastern boundary of Brookfield (as Lake Lillinonah): D/B. The severe D rating is due to PCB contaminated bottom sediments.

3. Still River from Danbury Line north to the New Milford Line: C/B.

4. All other streams in Brookfield such as Dingle Brook, Hop Brook, Merwin Brook, Limekiln Brook, etc: A/A.
