6~SSACHUSETFS—1990  249attributable to fewer construction starts
a decrease in highway construction projects. 
 In 1990, more than 100 companies mined construction sand and gravel in 13
counties. Leading counties, in order of output, were Middlesex, Worcester,
and Norfolk. The material was used mainly for concrete aggregate, fill, and
road base and coverings. 
 Boston Sand & Gravel Co. was awarded a 10-year contract by the Massachusetts
Water Resources Authority to supply the concrete for the massive $5 billion
Boston Harbor Project. The provisions in the $87.8 million contract state
that Boston Sand & Gravel will transport by barge all raw materials
a Deer Island central mixing facility it will build. The contract also required
that the company have access to, or own, an onshore location to load barges
and store materials. The Boston Harbor Project includes building the second
largest primary and secondary wastewater treatment facility in the Nation--an
almost 6-mile-long, 1 1 -foot-diameter, crossharbor tunnel to transport sewage
from Nut Island to Deer Island and a 9.5-mile, 24-foot-diameter ocean discharge
tunnel to carry treated wastewater from Deer Island to deep-ocean waters.
 Industrial.—Industrial sand was mined by one company in Plymouth
primarily for use in molding and core and in sandblasting. 
 Stone.—Stone production is surveyed by the U.S. Bureau of Mines
oddnumbered years only; data for evennumbered years are based on annual company
estimates. This chapter contains estimates for 1988 and 1990 and actual data
for 1989. 
 Crt~.t~d.—Crushed stone was the State's leading mineral commodity,
accounting for almost 43 % of the State's total value. Estimated stone production
in 1990 was 23 % lower than that in 1989. The 1990 estimated output of ).2
million tons was also 47 % lower than he alltime high output of 17.5 million
ons produced in 1988. Traprock (basalt) 
accounted for the majority of the stone produced, followed by granite and
limestone. Major uses included road base and concrete aggregates. 
 Dimension.—Massachusetts ranked eighth of the 34 States that reported
dimension stone production. Dimension granite, used primarily for curbing,
was quarried by six companies in Berkshire, Middlesex, and Plymouth Counties.
Dimension marble was quarried by one company in Berkshire County and sold
as rough blocks. 
 Vernziculile (&foliateO.—W. R. Grace & Co. exfoliated
vermiculite at its Easthampton plant in Hampshire County. Major uses were
for insulation and fireproofing.
